Lighting / Re: Entering the world of needing a flash at darker weddings
« on: November 13, 2012, 12:38:05 AM »
I have Stofens for my 430 and my 600.  I don't really like using them.  The colors/contrast I get from a bounced flash are much more pleasing.  The stofen might be a little more useful on the 430 as it does not have a catch light panel but I still find it much more useful to just use the flash directly. 

If you're looking for more interesting shadows, I'd use it off camera anyway...and I still don't use the stofen. 

I'd recommend the 580 or 600 for the higher output and easier controls.  (yes, it makes a difference in the real world).  For example, when bouncing flash straight up to an extremely high ceiling, like the ones found in reception rooms, the extra power is nice.  Also, when manually adjusting the output, the dials on the 580 and 600 are much easier to adjust quickly rather than having to hold down the center button for a few seconds and then pressing the +/- buttons, which are a bit tricky to press...minor gripe but it does slow me down a bit.  I mainly use my 430 to light backgrounds or if I need the extra power for bounce flash...usually off camera.

The controls on the 600 are far more intuitive - they are a big improvement in terms of reliability.

For wireless control, while it is probably the most expensive solution, the 600-EX-RT plus ST-E3-RT is probably the most bomb-proof solution.  If you are going to set up an off-camera flash, this combination has the added advantage of not having to attach a separate trigger, which gives for a faster and less error-prone setup to get your off-camer flash working.
Another added bonus is that the 600 comes with colour-correction gels for tungsten lighting.

I know you were underwhelmed by the 18-55mm kit lens - it would however be interesting to see some examples shot with that lens, and possibly some crops as well.

EOS Bodies / Re: Has Canon entered the Graveyard Spiral?
« on: November 12, 2012, 05:01:21 PM »
Should they rather focus on the point and shoot consumer market and leave the high end stuff to professionals?

That would surely be one-way a ticket to the graveyard, since the competition from mobile phones is steadily eliminating the entire consumer P&S market.

....they are going to continue losing market share to Nikon in my opinion.

So, you're saying that Nikon is going to continue their trend of gaining market share from Canon.  A trend that has lasted for exactly the one most recent quarter of the last four years.  Okay-dokay, we'll see...

Canon will also be acutely aware of any gains Nikon makes.  For instance, the D3s certainly had an advantage over the 1DmkIV.  By all of the accounts I have seen, the 1Dx and D4 seem to be close enough to each other that any difference is academic.

Canon has certainly jumped ahead in the flash department with the 600-EX-RT and ST-E3.  Nikon does not have anything like that yet. (It is a matter of time, I believe.)

Nikon still has not caught up in terms of the depth and breadth of lens selection Canon has.

Either way, competition is good, and innovation from Nikon will push Canon - and vice versa.  I doubt that anyone would be making a mistake right now choosing either Canon or Nikon.  Both of them make their slip-ups, but on average, both are putting some pretty damn awesome products into the market. - The choice probably really comes down to personal preference.

The sad thing in this market is that, if you want a full frame DSLR, there are only two games in town.  Everybody else has left the room and only Canon and Nikon are playing.  That is the real tragedy of the market today.  A serious third player (and Sony  really doesn't count right now) would make a big difference, and keep Canon and Nikon on their toes.

Third Party Manufacturers / Re: Photos of film's demise
« on: November 12, 2012, 04:34:09 PM »

My fear with digital is longevity. I've communicated with several restorers, archivists, etc. who universally say the only genuinely reliable long-term storage medium we have is paper. All digital storage formats degrade far more quickly than paper.

Maybe it's just me. I think most people don't care about the longevity. For me, there are few things more fascinating than looking at pictures from 80 or 100 years ago. A while back I resurrected my old prints and negatives from 40-50 years ago and was amazed. This raggedy old man was once a quite handsome young man in a military uniform! Without that picture, I would not have known. Will young people be able to look back 50 years from now at digital images s they make today?

You've hit on a point which isn't considered very often.  It is very interesting to see how few people actually consider the longevity of digital media. - For files stored on a hard drive, you essentially bargain on copying everything to a new hard drive every 5 years or so.  Good papers, depending on how they are stored, can have an archival life of up to 200 years.  - Try explaining that to a client who only keen on a digital package.

I suppose there's a bit of a distinction to be made between 'film is dead' and 'kodak is dead', and also between 'film is dead' and 'film for the masses is dead'.

The demise of Kodak is more a lesson in kodak completely cocking up almost everything they've done in the last 20 years, as a company they could be thriving, even in a purely digital world. They killed off kodachrome a few years ago, ektachrome just went this year, all that's left is TMax and BW400CN. They also used to make good Digital Sensors, and their paper and printing was really nice too. But they managed to cock that all up too. Ilford may have gone bust a few years ago but they're back and not doing too bad, and fuji is just mopping up all of kodak's old customers too.

But yes, 'film for the masses' is dead...
It is unfortunately true that Kodak has messed up almost everything in the last 20 years.  I will miss Endura papers, although, as you say, Fuji has done a pretty good job of mopping up Kodak's customers.  I think actually Fuji already started mopping up Kodak's customer base in the 1980s, well before the advent of mass market digital.

Film manufacturers will need to learn to live on in a much smaller scale - the mass market heyday of film is over.  The future is more niche - like the "Impossible Project".

I also certainly don't miss film.  I think digital has made photographers of all walks more productive and helped them to be more creative.  While one of my father's friends, who was a commercial photographer in Frankfurt decided that he could not make the leap to a digital workflow in his business, and rather retired - he could afford to, for my wife, starting up a studio from home, digital has been a major enabler.  With film we would have had to have dedicated another room to photography work for a darkroom.

Digital also reduces the cost (especially in terms of time spent) when you use an external lab for printing. - Now you only need to make one visit to the lab - to collect your products.

Aside from the specific technology involved, this is a great narrative about how important it is for (especially large) organisations to change in order to stay relevant.  Those who don't change with the times get consigned to the junk pile of history.  Fujifilm was one of the earlier adopters of digital, and benefited handsomely from that.  AGFA and Kodak stuffed it up.  I would say Canon and Nikon have benefited from Digital more by luck than design, purely because the move to digital has favoured camera manufacturers against producers of photographic consumables.

As much as I do hate the process of getting film developed, I am itching to go down the road and get another spool or two of Tmax or Tri-X, and see how the EOS 650 fares with the 24-70 f/2.8 II. ;-)

EOS-M / Re: EOS M EF to M Mount Adapter with 70-200 f/4L IS Sample Images
« on: November 12, 2012, 12:46:00 AM »
I don't understand, why people putting a "L" lens on mirrorless body :-\ It just looks so stupid.



If your mirrorless body is your second (or third, or fourth, or fifth, or sixth...) body, being able to attach any EF lens is a nice feature to have.  For instance, if you travel with a DLSR and a mirrorless body, you have your compact and backup bodies provided by the EOS-M.  (To establish whether that kind of setup is ideal is left as an exercise for the reader.)

For Canon, the EF mount adapter is a compromise to make the system look more flexible through the period when there are very few native lenses.

FWIW: I'm still not convinced of being to properly hand-hold a body which has no EVF (or eye-level viewfinder of any kind) with such a big lens attached.

EOS-M / Re: My First EOS-M Review
« on: November 11, 2012, 05:49:06 AM »
Excellent review, wickidwombat! Thanks for that.

It however confirms what I've been thinking from previous comments on the camera's performance: to wait and see where Canon will take the EOS-M system before jumping in at the first instance. For me, the poor AF performance (using the 'traditional' shutter button) is a deal breaker. Some more R&D to be done there...

I am hoping that the fact that the EOS-M seems to be doing very well in some markets (like Japan) will give it the scale for Canon to add other more advanced bodies.  Once there is one with an EVF, better AF and a socket for a wired remote shutter release, I'm in. - Oh, and also with a new sensor - I don't need another camera with the current 18MP sensor tech.

Lenses / Re: Bokeh Quality from Different Fullframes vs APS-C´s DLSRs?
« on: November 10, 2012, 10:25:33 PM »
What full frame gives you is MORE bokeh, not better bokeh (i.e. DoF is shallower).


It's my understanding that bokeh refers only to the quality of OOF blur, not the quantity. Therefore it can be better or worse, but 'more bokeh' is an non sequitur.


At least that is the way the OED sees it:

the visual quality of the out-of-focus areas of a photographic image, especially as rendered by a particular lens.

EOS Bodies - For Stills / Re: Full frame or not???
« on: November 09, 2012, 11:30:43 PM »
The 24-105 f/4 is a very popular lens amongst wedding shooters in Melbourne. - Even Yervant uses it.

While a f/2.8 zoom is a blessing in terms of having the extra stop of light and more accurate AF, a lot of the time a wider aperture only affords you enough DoF to get one person in focus  - unless all your subjects are parallel to your focal plane, which is often not true.

If you are only shooting with one body, the 24-105 also allows you the benefit of not having to change lenses as often.  - Apart from 1 stop less light, the 24-105's bokeh is nowhere near as nice as the 24-70 f/2.8II.

My wife started out shooting weddings using mainly the 24-105 (partly because of not having other lenses), but is gravitating more towards the combination of the 24-70 f/2.8II and 70-200 f/2.8 IS USM II.  The double Blackrapid strap just arrived in the post this week ;-)

Someone else made the comment about using a cheaper prime to make up for the lack of a f/2.8 zoom - that was one of the strategies my wife applied as well - taking along a 50mm f/1.4 as well and using it when she really needed low light performance.

« on: November 08, 2012, 11:53:23 PM »
Okay, 15mm on the 5D would give you a pretty good field of view, and you can always defish if necessary.

The 70-200/2.8 IS II is much sharper than the /2.8 non-IS, especially with the teleconverter.

A tilt/shift lens would be fun to play with, too...


Just a comment on the 15mm f/2.8 fisheye - this lens is now discontinued, the only fisheye than Canon currently produces is the 8-15mm f/4L.  You can probably pick the 15mm fisheye up 2nd hand if you really want it.

Calydus, they are thorough, but sadly there is sample variation. Their results certainly don't square with mine, which would suggest their copy is towards the bottom of the pile. I don't even need to run a test chart. Its blindingly obvious from the few hundred files I have shot. I thought my 70-200 F4 L was good, but this lens is a definite notch up on that and light years ahead of my Sigma 24-60 f2.8. I might test it against my 24 1.4L II, but I can already see the new zoom will match it, if it does not surpass it. Gut feeling tells me the zoom has more contrast than the prime too. 


I am now beginning to think that is probably the only place were photozone.de's process falls down.

In order to review a lens properly, you need to review a statistically relevant sample of the overall population of that lens.  That probably represents a cost which the guys at photozone could not stomach.

Ultimately, a really thorough review would also give a view of the expected sample variation in the population, as this is also an important characteristic of the quality of a lens - i.e. the lower the variance of the quality the better the manufacturing and QA process is, and the higher the likelihood that you as a purchaser will get a good copy.

Now if the guys at Photozone.de had access to the stock at Lensrentals.com..... (Unfortunately, that would require some tectonic engineering to achieve.)

When can I hope for the next rebate program? Nothing before Xmas? right after?

At least in the European rebate programs Canon in just discounting older and standard lenses and some tele zooms - I wouldn't hope for an official discount on this one for one or even two years to come I'm afraid to say. More likely they'll do a kit with the 5d3 sooner or later, I remember it's been seen in Australia.

Kit Lens?  For which camera?  I don't think this will ever be a kit lens.

As Marsu42 posted, this is already a kit lens in some markets (Australia/NZ and maybe others).

I can confirm it is available as a kit in AU.  I think the single box for the kit is taking longer to reach all dealers - we got ours as 2 separate boxes (not the one shown in the image).

You will find almost all Australian dealers are advertising this kit, which is advertised for about $6099 (including GST) but which can be had for around $5800 if you haggle a little. - That's about $5272 excl GST for those wanting to compare to American prices.

It seems like a great lens, but the price just kills it for me. I still can't understand how Canon keeps coming out with new products at higher price points than ever while the world has been in a global recession and economies continue to suffer. It's very short sighted and clueless of Canon. I would buy this in a heart beat if it was $1,700.

After my 48 hour evaluation I'd buy one in a heartbeat if I could just get my hands on one. It's a two-three week wait where I live.

The price? I think I paid around $2200 when the MkI was released in November 2002. After ten years Canon would have well and truly made back their ROI on the MkI, enabling price reductions. I'd say for a new model this could be seen as a price drop when seen in its historical context. Canon has profit obligations to its shareholders. They're not a charity. Study supply & demand. Sometimes it's a valid & viable business strategy to be reassuringly expensive. It works for me.

-PW

I haven't spent nearly as much time as you with this lens, but what I have experienced so far is similar to what you describe.  So far my perception is also that the colour rendition is very good.

In my mind, the only concern so far with this lens is that there seems to be some copy variance, which may be significant. - I can't help but wonder if the guys at photozone.de got one of the "inferior" copies.

EOS Bodies / Re: Where the heck is the 70D or 7D mkII?
« on: November 08, 2012, 06:03:11 PM »

So, no...the 6D sensor will not really bring any kind of major sensor fabrication improvements to the table. Canon has experimented with and prototyped sensors on a 180nm Cu wiring fabrication process. Their 50mp APS-H and the 120mp APS-H both used a 180nm process. They have prototyped 180nm sensors that make use of high refractive index lightpipe technology for higher Q.E. that approaches the performance of BSI sensor designs. Based on the 120mp press releases, it even sounds like they have some kind of CP-ADC technology. But they have not yet put any commercial-grade high-volume sensor fabrication on those processes yet (god only knows why...if they don't do so soon, they will really be in a competitive bind.) Regardless, it is highly, highly doubtful that the 6D will offer any kind of major IQ improvements over anything on the market today, and it most likely will use the same 500nm process as every other Canon sensor released in the past decade.

For these reasons, I will be intrigued to see what Canon's next APS-C sensor looks like.  I have my doubts that Canon can get anything more out of the current 500nm process.  I suspect that any significant improvement in Canon's APS-C sensors would require a move to a newer process.
I have my doubts that we will see anything being announced before February or March next year, so we probably still have a while to wait before we see Canon play its hand.

What I suspect would be a likely approach from Canon is to move its APS-C sensors to a new process - possibly next year, while it carries on using the 500nm process for full frame for another 3 years or so, until the 1DX and 5DIII are replaced.  That would probably be done in order to achieve the required manufacturing costs.

While film doesn't really occupy front of mind for many of us any more, this is an interesting view into the last days of the film industry:

Personally, I only started my migration to digital just over 12 years ago, so I still have boxes full of negatives packed away.

It also makes me think of the fond memories of slide shows, which formed the central event of many get-togethers with friends when I was a child. - My father still has an entire cupboard full of slides, covering a period from the early 1960s to the late 1990s.

What is also interesting is to see a generation growing up who have never known film.  One thing I do hope to show my children when they are a little older is how my wife and I used to take photos before the arrival of digital photography.

Lenses / Re: Bokeh Quality from Different Fullframes vs APS-C´s DLSRs?
« on: November 08, 2012, 06:16:46 AM »
actually i think the 'quality' of the bokeh is more down to the quantity and shape of the blades in the aperture...  i.e. more blades a rounder bokeh...  a fun thing to do is to cut holes of various shapes out of card and hold over the lens to give different shaped bokeh...

The quantity and shape of the aperture blades will impact the shape of out-of-focus highlights - hence the pentagonal highlights from the nifty fifty, because it has 5 aperture blades.  The "smoothness" of the blur is affected more by the optical design.  Here you will see factors like whether the bokeh is smooth (e.g. 85mm f/1.2) or perhaps more "nervous" (like the 24-105mm f/4 can be).  Other characteristics which have also been mentioned include "cats eyes" (in the out-of-focus highlights nearer the edge of the frame) and "onion rings" at the edges of highlights.
Some lenses also differ in the quality of the background blur relative to the foreground blur.  For instance, the 85mm f/1.2 is well-known for not only delivering a very creamy background blur, but also a very smooth foreground blur. - Many lenses do not do so well in terms of the quality of their foreground blur (which tends, generally to be less of an issue than background blur).
