Lenses / Re: Why no lenses like 35-135mm anymore?
« on: June 16, 2013, 06:40:23 PM »
Yes, I could see a 35-135mm f/2.8 as being a very useful lens for some situations (eg street photography, candids at camps, events, etc)

There is the Tokina AF 50-135mm f/2.8 AT-X Pro DX - some reviews of it in different mounts at - and it does well, particularly at the wide end across the frame, and tele end centre is great, just a bit soft in the corners wide open. But just 1 stop down the corners improve substantially.

There are also 3 versions of the Sigma 50-150mm, two of which are tested at  (they vII they appeared to have a very decentred copy).  But the vI Sigma 50-150mm ƒ/2.8 EX DC OS HSM APO they tested is amazingly sharp across the frame at all focal lengths, even wide open.

To me I know I would find a 35-150mm f/2.8 image stabilised lens 'ideal' for many of my purposes - that is, that focal length on an APS-C (Canon 7D).  For FF I'd want to use a 70-200mm f/2.8 though.

Here's hoping!!! I have a 70-300mm L - which is what I use for my wildlife / bird photography (as I don't need fast glass for that)... and my walkaround is my Canon 15-85mm. A moderate fast (that is f/2.8) 35-150mm would be great for people photography or subject isolation.... so yes, it would also fill a niche for me.

At times I use my Canon 100mm f/2.8 USM macro for subject isolation (ie - not macro) - which does well in that too- but just at 100mm obviously!

Welcome to CR forums.

I agree that f/2.8 is very handy for night time photography.... and so the Canon 16-35mm L would be a good consideration. Not tack sharp wide open, but still reasonably sharp - but you might need the f/2.8.  Do you need wider than the 24mm? And do you have the 24-70mm v1 or v2?

Other options - yes the Canon 14mm L or one of the TSE lens. Or Canon 17-40mm which is very good stopped down.  I don't do much astrophotography, so my criteria are different (I do more daylight landscape photography UWA).

Your Sigma 8-16mm won't work on a FF. For what it's worth, I've seen a lot (!) of very good images with a crop sensor (APS-C) using many UWAs - eg Sigma 8-16mm, Sigma 10-20mm, Tokina 11-16 (f/2.8!), Tokina 12-24mm and Canon's 10-22mm.  We're really spoiled for choice!

Then, on the other hand, perhaps you want to consider a telezoom- eg 70-200mm f/2.8 II or the 70-300mm L (which I have).  I also take quite a lot of landscape shots with these (eg zooming into mountains, along coastlines, even forests, etc).

Pricewatch Deals / Re: Sigma 18-35 f/1.8 DC Available for Preorder
« on: June 14, 2013, 12:30:19 PM »
I congratulate Sigma for designing and producing this ground-breaking lens. A f/1.8 zoom for DSLR (admittedly limited to APS-C sensored camera bodies - but still it's an impressive design).

And... according to SLRgear - who have just tested this lens, it performs very well! Read their 'rave review' here:    8)

As this lens doesn't suit my style of photography - I don't expect to purchase it (even though the price is very reasonable). However I do think many people will be happy to buy the lens at the price of $799 USD.

Well done Sigma... looking forward to more quality technology in the future.  ;)


I am curious to know what people that photograph other things would do too! Thats why I said that.

But if you want to know, I like to photograph people working, not rich people, people from deep Brazil, where I live now. In the farms for example.

(I'm talking about $2000 in US prices, of course).

Firstly, I echo's comment - to be thankful (that many people would love to have a 5DmkII and $2000 available to them - and I'm sure you know that from Brazil too).

I do quite a lot of 'people in an environment' style photography - eg recovery / therapy camps for adults and children, church events, some casual sports, etc - though I wouldn't say this is my 'preferred' photographic genre, nor even an area I have most of my skill in.

The lens that I find is the most useful on my Canon 7D for most of my 'people shots' is the very good Canon EF-S 15-85mm. That lens covers equivalent of 24-136mm in FF format. I have also used and owned a good copy of the Canon EF 28-135mm, and the EF-S Canon 18-55mm.

So while it depends on the type of environment you would photograph people (as you said, on farms) - eg mainly outdoor, in large expanses, or up close, detailed work, etc - for FF I would want something of the focal range of the Canon EF 24-105mm L - which gives you both the possibility of context (eg wide angle) and some telephoto (at 105mm). With FF one has more potential for thinner depth of field, even with an f/4 - that can produce some shallow depth of field and have decent bokeh. ;)

Next I would get the 70-200mm f/4 L IS - which would give you some creative potential for more telephoto. And having IS is invaluable here (especially @ f/4). I think if you shopped around and were careful, you could buy both the 24-105mm L and 70-200 f/4 L IS new for about $2000 US.  If new wasn't a possibility - I'd get one (or both) of them refurbed from Canon.

While I own and prefer the Canon 70-300mm L over the 70-200mm f/4 IS - this 70-300mm L is more expensive -and perhaps there are fewer 'deals' going on it too. The 70-300mm L really shines on my 7D, and I've used that for people photography too, it has great sharpness and exceptionally good bokeh for a relatively slow telezoom.

So, in summary if you can - perhaps get the 24-105mm L IS and the 70-200mm L f/4 IS.  Good to great image quality from both lenses, relatively light (eg transportable, etc) - and both have USM and IS - which are really helpful features to have.   And after using these 2 lenses for some time, you may have saved some money and will find out if you need an other lens, eg a fast prime, and at what focal length, or maybe an ultra-wide angle (for that 'special UWA effect').  I doubt that I'd want to get a prime unless you have some time and experience in shooting the style of photography that you're talking about.  :)

Hope my input helps.

Ankorwatt... I really like the photos you have shared here... and am glad to read that you realise the Canon 200-400 would be able to take even higher quality images.

Lenses / Re: 400 2.8 vs 200-400 4.0 1.4
« on: June 13, 2013, 11:45:05 PM »
I'd love to have the new EF Canon 200-400mm f/4 1.4x USM IS lens.... and yes, I'd also have that over the 400mm f/2.8.  The flexibility to have from 200mm (@ f/4) to 500mm (@ f/5.6) on tap is something I would love, particularly for wildlife (animals and birds). Most of my shooting is in good light - a blessing of being in Australia where there is plenty of light often. But even in darker situations, a capable photographer could make this lens sing!

No doubt the 400mm f/2.8 has the advantage in some situations (ie where you are perfectly positioned to fill the frame / compose at 400mm - and in darker light). That's not the style of photography for everyone. I can see many people really loving this lens and buying it (admittedly probably mostly pro's or enthusiasts with higher disposable incomes).

Even above the reviews that will no doubt start to trickle out over the interweb, I look forward to seeing some great quality PHOTOS from this lens too!   8)



Reviews / Re: Problems with Canon 7D
« on: June 13, 2013, 11:40:34 PM »
It's a shame far too many people are 'experts' at the 'limitations' of their photography gear (especially cameras & lenses) - and make so much more effort pixel peeping, reviewing, comparing, etc - rather than actually just getting out and taking, enjoying and sharing: PHOTOS!  :o

I have a Canon 7D. It was my 2nd DSLR (after buying the Canon 350D in 2005).  I had a number of digital point and shoot (P&S) cameras for the 8 years prior, and used film before that. 1 week ago (Friday evening 7 June 2013) using my Canon 7D with Canon 15-85mm lens - I took about 50 photos for a friend's 40th birthday party. Most of the photos were with the camera's 'pop up flash'.  The party was a 1920's themed evening with friends and relatives in a cocktail bar near the beach. It's winter here, in Australia- so it was already dark - and quite mild (not swimming temperature).

Were the photos the best (eg given I didn't use my external flash)? No. Are the photos worthy of National Geographic or some quality glamour / fashion magazine? No. Am I particularly skilled in this genre of photography? No.  However did my friend appreciate me taking the time and effort to take my camera along and spend about an hour of the evening with the camera around my neck - and taking these photos for her? Absolutely!  She thanked me many times, as did many of the other guests and friends who have seen the photos on an online album I uploaded them to.

The photos my 7D captured that evening are noticeably superior to the photos others took with their smart phones or P&S cameras of that evening. Part of that I attribute to my photography skills being higher than the average person, and also the capabilities of my gear (and that I know how to use them).  ;)

So while the OP might have a gripe about several aspects of the Canon 7D... I love my camera - and use it, and my 5 lenses in all sorts of situations (from landscape to wildlife to macro to event photography to casual sports to architecture to travel to people / portraits).

The 7D outclassed other APS-C cameras when it came out. It's no worse now than when it was released 4 years ago. I'm still very happy with it - particularly the AF, FPS and build quality. Sure I'd like lower noise, etc. But for what it is - a capable photographer can get many wonderful photos from the Canon 7D.  Hey, I even have many photos from my other cameras - Canon 350D and even P&S cameras - that people admire  (and yes, I do have friends who are concerned about quality of photos!)

Please go out: use and enjoy your camera, lenses and whatever other gear!   :)


EOS Bodies / Re: A Big Megapixel Discussion
« on: June 13, 2013, 02:52:13 AM »
Either 34.56mp (4800x7200) or 56.62mp (6144x9216; extra credit for seeing why I chose the latter numbers).



So it's the same pixel density as a 1.6 crop sensor with three horizontal pixels per output horizontal pixel in full HD video mode.

Fascinating.  That was not what I was looking at at all.

I was thinking 256 pixels per mm (vice 200 pixels per mm for the 7200).  I like your answer better.  Well done.

I figured it was just that the first one was 34560000 pixels, which is a cool number.  :D

+1  :)

I look forward to high number of mega-pickles if they are sharp per pixel - and don't impact DR and noise too much - coz that's good for cropping!  ;)

I think some of us (and this is not an indictment) are getting hung up in F/1.4 vs. F/2.  It's just one stop.  The other improvements -- general overall sharpness, internal focusing, IS, much much faster focusing, better build -- would have me buy this lens at F/2 or F/1.4. 

I know I am in the minority here, but I'd gladly give up one stop for all those improvements.

As for 50Lv2, agree.  It doesn't even stack up to the current F/1.4 in the corners.  For 3-4x the price, it should everything the cheaper one does and more.

In part I do agree with you - personally my needs and style of photography means that I'm not so hung up on the maximum aperture issue (ie between f/1.4 - f/2). However I wouldn't want anything slower than f/2 - though I do understand there are people who need f/1.4 (rather than f/2).  :)

Particularly if there the lens comes with IS - f/2 would work great for certain applications.  And having a robust focus (STM as a minimum, or true ring USM as my preference) - ie fast, accurate, consistent.

More importantly, I want the next Canon 50mm lens - to have great IQ (sharp, contrasty, smooth bokeh, low CAs, little vignetting) when it's wide open.  ;)

Then if anything the lens' IQ should 'improve from there' in the range f/wide-open till f/5.6. I doubt I'll use such a lens at smaller apertures than f/5.6.

The new EF Canon 35mm f/2 IS USM looks attractive... just I use the 50mm focus length more than I use 35mm.  I'd be prepared to spend up to $1000 AUD for a lens that fits the bill. I'm looking forward to what might be around the corner....  8)


Lenses / Re: Aperture Sweet Spot
« on: June 10, 2013, 08:43:13 PM »
There are so many variables here - by lenses (both primes and zoom)... as has already been written, it's impossible to make one statement about 'aperture sweet spot' in terms of image quality (IQ).

A few examples (and comparisons) from my person experience with various lenses:

1) Canon EF 28-135mm f/3.5-5.6 IS USM. My copy was 'decent' (but not fabulous) wide open across the zoom range, but noticeably sharper and had more contrast 1 stop down. I've since sold the lens (as I bought the Canon EF-S 15-85mm f/3.5-5.6 IS USM which is superior and has better IQ across the zoom range - even wide open)

2) Canon EF 100-300mm f/4.5-5.6 USM. This lens was quite sharp & had good contrast wide open at the wide end (ie 100 to ~170mm).  It got progressively worse (soft, low contrast and higher CA) towards the tele-end. At 300mm I had to stop down to about f/10 for the 'best' IQ.
Note: f/10 without IS at 300mm (480mm FF equivalent) needs IS in many situations - or high ISO - which often degrades quality anyway.
Again I sold this 'old' lens - when I replaced it with the Canon EF 70-300mm L f/4-5.6 IS USM - which is much sharper and has great constrast wide open at all focal lengths - even at 300mm f/5.6 my copy if great - just a touch of stellar when pixel peeping... So that's fantastic!! (Note: that 4-stop IS helps so much!)

3) Canon EF 100mm f/2.8 USM - my copy is very sharp already at f/2.8 and is perhaps the sharpest between f/4-5.6, though often I either shoot wide open (ie at f/2.8 for subject isolation) or at around f/11 - f/22 for when I need more depth of field in some macro situations. The lens is still reasonably sharp at f/14-f/22 but defraction is somewhat noticeable and sets in more.

4) Sigma AF 10-20mm f/4-5.6 EX DC HSM - my copy has 'reasonable' sharpness and contrast at 10mm wide open (f/4), and is a bit better by f/5.6.... Similarly at the tele end of 20mm - sharpness and contrast are somewhat better at f/7.1 than f/5.6.  Thankfully the sharpness / contrast is already quite good wide open, and at these ultra wide angles, depth of field even at f/5.6 is considerably deep!

5) Canon EF 50mm f/1.8 mk II - I had 2 copies - both were 'ok' at f/1.8 - but not as sharp or as contrasty as would be ideal (the main issue I had with both copies- 1st lens worse than the 2nd) - was AF - slow, inaccurate and inconsistent.  Stopped down between f/2.2-f/2.8 it had noticeably better IQ.  Then from f/2.8 to f8 it was very sharp (if AF was 'on').  So what do I want? A new Canon EF 50mm prime which has great IQ wide open, including lovely bokeh!

Well, that is my contribution. Hope it's helpful.


Lenses / Re: Why Does the 100-400L Sell So Well Still ?
« on: June 05, 2013, 07:07:05 PM »
It continues to sell well because it's a very good lens, and the only 'affordable' way to get 400mm with IS.

+1  I wouldn't buy the 400mm f/5.6 prime because of 2 reasons
a) it doesn't have IS and
b) isn't a zoom

Most of my telephone zoom photos - eg birds - are often up close, or where zooming helps in composing / capturing the subject (eg BIF - then zooming in)

So I can understand how for many the 100-400mm L meets their needs.

For me, I much prefer the design (ie size, shape, zoom mechanism) of the 70-300mm L.  The 'big deal'  is that I can transport my 70-300mm L in my Lowepro shoulder bag, with my 7D and 15-85mm lens (either lens attached) and shoot all day with it.  This is my perfect 'travel zoom combination'  - and I might throw in a prime (or my UWA) for certain situations.

More often than not however, my 2 lens combo is the 70-300mm L and 15-85mm.  The 100-400mm L is substantially longer and more difficult to transport & carry than the 70-300mm L. Still I can understand it's a great lens for many ppl who really want that 400mm reach.  The 100-400mm L isn't quite as sharp as the 70-300mm L nor has the newer IS or quite the same AF speed / accuracy (just a bit slower / more hunting in my experience)- but the 100-400mm L is still a very decent lens!


Canon General / Re: Newspaper Dumps Photographers, Wants Video
« on: June 05, 2013, 02:09:03 AM »
I've found the following regarding 'news turns video' (from written article with a photo or few):
1) the quality of many news videos is often poor (quality of sound, shake, background distraction, etc).
2) it takes me MUCH longer to scan and/or receive information.

So when there are video links in news items (particularly if they are the main / only source of information in that article) - I will avoid it.

For years I haven't looked at news on TV (since the late 80's regularly - and since the early 90's I haven't used TV for news pretty much at all).
Both at work (in my breaks) - and at home - I want to choose what to read, by clicking on news headlines, and read the top paragraph - that will determine whether I need or want to read more. Only for world breaking news (eg huge natural calamity, or outbreak of war, or a truly good news story) - might I tune into TV, or view news videos online. That's only about once every few months (at most!)

I will continue to enjoy photography as a hobby - and appreciate seeing others' quality photography in various media (online, magazines, newspapers, etc).  Even though video is taking over some of the traditionally 'written and photographed' articles - there will always be a place for it. And I expect quality publications will still reserve a space for photos and written articles. Who knows, there might even be a return to that some day!



I've lived in 3 different countries for periods of some years each, and have visited many more countries for 'some week to some months' each.

Sad that in some parts of the world there is so much fear about 'street photography'- and indeed even aggression when a photographer is around with his / her camera in hand. I have researched the laws in various countries and know my rights. I also am an official photographer for events (eg some sports events, church events, youth camps, official openings, etc)

Thankfully I've never been threatened, or felt very harrassed. I am naturally a friendly, smiley guy. But stereotypes are difficult, as I'm a non-married middle aged male - so if I'm alone (eg on a beach) some people might think I'm there to capture photos of unsuspecting people ... for sinister purposes, which is far from the truth! :/  Usually though when I'm at the beach I'm with friends - so that does feel 'easier' if I have my camera then, and especially if they have their phones and/or cameras out too! :)

Only once (about 5 or 6 years ago) when I was photographing crashing  waves on quite a remote beach, did one young surfer (read about 20?) stop surfing and come to me and ask if I was taking photos of him and his mates. I said I wasn't, I was capturing the waves and landscape. He asked me not to take photos of them. I responded in a friendly manner: "No worries mate, as I said I wasn't doing that and I won't take any photos of you". However that was the only exception.

When I travelled to Thailand, for example - I used my 7D with 15-85mm most of the time, especially around people (only using my L white glass less often).  I was very thankful to note the friendly and open nature of the Thai people I met. I usually started conversations with people first anyway - that's just my nature.

But I know from various parts of the world - and for some - religion also has an impact on this - photography is much more difficult and threatening. While I prefer visiting 'friendly / safe' places - if in an area of 'photography vulnerability' - I'd probably not take so many photos, and no where there is a feeling people don't like it.

Lenses / Re: Anything shot with 70-200 f4 IS USM + 7D
« on: May 28, 2013, 08:02:26 AM »
I have used the 70-200mm f/4 L IS USM- and I own a 7D.

However for my purposes, the 70-300mm f/4-5.6 L IS USM won from a perspective of having an extra 100mm reach, and being almost as 'fast' as the f/4 for the same mm (it stays f/4 for quite a while, and then f/4.5, etc). So I bought the 70-300mm L soon after it was released.

Most reviews will show that both lenses are very sharp, even wide open. My 70-300mm L is still very sharp at 300mm f/5.6 (the setting I use most) - but it is a bit sharper at 70mm (if I look closely). But at 300mm f/5.6 it still knocks the socks of most lenses. Though it needs to be taken into account there is sample to sample lens variation in IQ.

The 7D is definitely more demanding on lenses than eg an 8MP or 12MP equivalent APS-C.  I have a number of lenses, and eg the 15-85mm really outshone my (now sold) 28-135mm on the 7D.  But on the 350D, while the difference between these 2 lenses was noticeable, the difference was not AS noticeable as on the 7D.

I can highly recommend the 70-200mm f/4 L IS USM, but recommend the 70-300mm L if you can afford the extra bit of money. The 70-300mm L is very hand-holdable (it's 4-stop IS is very good, and its USM focus very fast & accurate). Though built like a tank, it's not too heavy to transport (or have in a bag) all day. I like it's 'stumpy' design and that the zoom ring is at the end of the lens (that's what I prefer!).


EOS Bodies - For Stills / Re: 6D vs. 600D with good lenses?
« on: May 27, 2013, 01:58:01 AM »
More flexibility in low light performance and range both wide and tele with option #1. On the 600d you would have had to find a lens that is 15-65mm to match the same focal length of 24-105mm on 6D. DOF of f/4 on 6D is also compared to f/2.5 on 600D. The boost in ISO performance and overall look of the images is also better with full frame, but I wouldn't spend that kind of money for street shots if I could barely afford it, you should make the bigger purchases if you know your finances can take the hit or if it will be an investment that pays for itself short term. But of course, in the end, you still buy what you want because it's your money. ;)

Certainly FF has advantages of more control of depth of field (DOF) ie by definition of having a larger sensor, a shallower DOF is easier possible - with the same aperture.  And FF has the advantage of generally lower noise, so in that regard the 6D would be a good option.

However there is a place for APS-C (eg 600D or 60D) too. Firstly there are many great EF-S lenses, eg the 15-85mm f/3.5-5.6 which covers 24-135mm in FF format. True, this is a slowish lens. The 17-55mm f/2.8 is a faster lens. Though for truly shallow DOF, a dedicated fast prime (eg f/1.2 - f/2) is more suitable.

UWA, there are so many great lens options - from various manufacturers, many of which are sharp corner to corner, contesting the best L UWAs. Eg the Canon 10-22mm, Sigma 10-20mm, Sigma 8-16mm.

The 7D's AF is great for street photography (19 cross type AF points, well spread across the composition). Most EF-S lenses are less expensive than their FF 'equivalent'. No doubt if money is no barrier, then go for FF- and get a 6D (or even a 5DmkIII or 1DX).  But generally people don't choose the 5DmkIII or 1DX because of financial limitations - and needing to keep sufficient funds for decent glass.
