Each to their own. If someone want a Fuji XT-1 so what ? It's a great little camera.

Regarding Luminous Landscape: well let me put it this way. Many of the best images posted on Canon Rumors leave LL in the dust.

And some of their recent articles have just been ???

Like the majority of us on this site, I tend to read something about photography on a daily basis and I try to absorb as much as possible.

One of the things that I've noted, is the popularity of the 24mm focal length.

It certainly is a focal length that is present in many different lenses and as I'm typing here, I can think of at least 8 lenses that have 24mm in it's range.

I have one lens which incorporates this focal length and that is my 24-70 mkii.

But I have a confession to make, I can't 'see' photography in 24mm and I think I'm losing out on what may be the most versatile focal length in digital photography. In fact, I would ask, is 24mm to digital photography what 35mm was to film?

What I mean by 'see' is that when I'm shooting with my 100mm macro or 400mm, I can envision what I want to capture and snap the shot.
I think a big reason for this is that I know what appeals to macro photography and bird/wildlife photography so I kinda have a feel for the 'psychology' of these focal lengths.

I am however stumped as to what I can do with the 24mm focal length.

Is it best as a people lens? What does it bring for landscapes? What other genres benefits from shooting at 24mm?

This may be somewhat of an odd question and I can imagine many wouldn't find this topic interesting but I fear I bought the 24-70 in a question to own the holy trinity but I never envisioned what to do with the lens.

I'm looking for that EUREKA moment where I get what this lens and specifically 24mm is about and will know instinctively to use this lens in a specific scenario.

Once again, I understand if this thread only returns a few replies (actually I'm hoping for just one ) but I'm looking to explore different aspects of photography this year as opposed to being fixated on gear talk and tech babble.

What do you guys 'see' when you reach for your 24mm? What do you expect from the final image?

I have two zoom lenses that cover this FL and I used it mostly for landscape and large group of people despite tha fact I found sometimes too much distortion at the borders.
I rather use the 35mm FL more often than the 24mm FL.

Hi

I just my 7D M2 and really like the option to have multiple My Menu tabs. It would be great if Canon would add these to their existing cameras (1Dx, 5D M3, 6D, 70D).

A couple of observations - I can not figure out how to turn of unused metering modes. I only used evaluative and spot, never use central weighted or ....

Also found that they focus was a bit soft with my 200-400. The camera arrived Wed and Thursday I took it on a family trip (mostly shake down). I did a bit of AFAIM (I think +7 at the long end of the lens), with my 1Dx I don't need a AFAIM on this lens.

I have not had time to test other lens on this camera yet.

Happy to help. It's just a hobby, really...well, a hobby that assists me in my other hobby, really. I like to know everything about what I do, so as a photographer, well, I had to know how sensors and lenses worked. So I researched it.

Click to expand...

Just wanted to point out that the lp/mm for each sensor posted way above are only correct if you have monochrome sensors with tiny pixels (low fill factor) without microlenses and without an AA filter. If you have a Bayer sensor with real pixels and an AA filter, you're going to need at least 2.5 and maybe closer to 3 pixels per line pair.

Click to expand...

If you actually read my post, I stated as much.

Click to expand...

You made a passing reference to this in a different post and then posted wrong numbers and proceeded to reference those wrong numbers. If you knew this, why not just use more correct numbers?

What wrong numbers? I stated that they assumed a monochrome sensor. Why did I assume monochrome, rather than something else? Because there are a lot of factors that greatly complicate "reality", and I preferred to keep things simple, as not everyone is a mathematician or an engineer. It's easy enough to approximate after the fact to account for other blurring factors. You may care that everything is 100% perfectly exact...most people don't. And when my goal is just to get across the concept, absolute exactitude doesn't matter.

BTW, I did not make a passing reference to the fact that I assumed mono in another post. I made a direct reference in the post I made in this thread:

Thanks for the help guys problem fixed. I had no idea the AF sensor was so small in the bottom of the camera I had previously been blowing air at the screen up top. But once I used the air down loan at the sensor my focus points started working again. I was | | close to sending it in to canon for repair.

Yes, dust on the AF array is the usual problem, but something that no one really seems to take seriously, or even be aware of.

Everyone seems to forget that the Canon 50mm f1.8 has beautiful bokeh when shot wide open. It's got a circular "straight though" light path. The only issues occur when it's stopped down and the low number of straight edged aperture blades comes into play.

Good point, but of course this severely limits you in your creativity as you essentially are fixed to the "native" depth of field of the camera. And you're hit for six in bright light when your shutter is maxed out unless you use a nd filter. I often used to use my 50/1.8 stopped down since the sharpness is really mediocre wide open on ~20mp digital.

Re: Canon EF 100-400 f/4.5-5.6L IS II & EF 400 f/4 DO IS II To Begin Shipping This Week

balvert said:
My wife and I are both into wildlife and bird photography. She keeps taking my EF400 f/5.6L and I and up using my EF 70-300L. I have been debating whether to buy another EF400 f/5.6 or the new 100-400 Zoom. I really like the EF400 f/5.6 however I was hesitant to buy a duplicate lens. Also the EF400 has a long minimum focus. Finally pulled the trigger on the new zoom this morning due to IS, shorter minimum focus and versatility. If it is as sharp as the 400 I will be a happy camper. Just hope that Adorama doesn't surprise me with a back order.

The only area two areas the prime can excel in over the new zoom is a slightly longer focal length. The prime has a real world 400mm against the zooms real world 380mm. And lightness. The prime is a lot lighter in weight and the zoom. Most users of the zoom will be racking out to the long end anyhow, so the improved AF speed should match the prime. The new IS will be a nice feature, but not so useful for Birds in Flight. The improved Min Focus distance will be nice for close up portraits of birds and the like (which I currently do with a 70-200 f2.8 LIS II and a tele converter). Only you can say if these features are worth the cost of replacement.

I am more interested in seeing the 135mm f/1.8 DG OS, 85mm f/1.4 DG and 24mm f/1.4 DG Art lenses. These will have an enormous impact on Canon (and also Nikon).
I had the curren Sigma 85mm f/1.4 and only sold it because I needed money and haven't purchased it again waiting to see if Sigma refresh it. Hopefully, the 135mm and 24mm will be priced well below Canon ones.

Click to expand...

I love Sigma's Art lenses. I'm with you on these two, although I'd prefer seeing the 85/1.4 come out first simply because the very good Canon 135 is pretty inexpensive. I'd sell my Canon copy if the Sigma Art lens is good, however.

The only other amazing 85 is Canon's, and that's $2100. Unngh...

Yes, from my long experience with Sigma...quality control and focusing accuracy is a lottery.

Its interesting to compare the lens at 400mm on the 7D MK II wide open at f/5.6 versus wide open on a 1Ds MK III with 1.4X TC. Note, the lens is better wide open than stopped down, and matches the FF in the corner, but not quite in the center when wide open.

The images are very carefully set up and manually focused to be the best the camera can do. The 7D MK II is a hair better than the 60D, since it has a few more MP, the improvement is proportional.

I wish he had included the 1D MK IV in those tests.

7D MK II at 400mm f/5.6 (center)

7D MK II at 400mm f/5.6 (corner)

1DS MK III with 1.4X TC wide open - f/8 (center)

1DS MK III with 1.4X TC wide open - f/8 (corner)

This will make zero noticeable difference in real world photos unless you are shooting lens charts in a lab.
I'm pretty confident in saying both the new 100-400L and the 7DII will sell very well for Canon and for good reason.

Can anyone with a good understanding of MTF charts and actual field experience share how the three 24-70mm lenses compares to each other in terms of distortion (especially at wide end)? I have been using the 24-70mm f2.8L I for more than 4 years but sometimes borders sharpness and distortion particularly at the wide end annoy me so, I would like to know if the 24-70mm f/2.8L II or the 24-70mm f4L IS offer more controlled distortion.

Most appreciated!

Why does this minor metric matter so much to you? It won't make a good or bad photo any better or worse? It's easily corrected with one click in Lightroom. Are you looking to justify a new lens purchase? If so...go and buy it and enjoy but don't think it will change your photography much! It'll just give you something new to play with. The photos will be the same, according to your luck and talent. New gear doesn't equal better photos.

You, Sir, are the most gracious member of this board! It is my pleasure to attempt answering your question, but I'm afraid I have just confirmed that the Phottix and Yongnuo are not compatible...

T approximately $40 each, the YN-622C trigger/transceiver is a most wonderful addition to the 568EX II. And now I see that the 568 EX II is down to approximately $120, making possible a complete radio triggered "580 EX" flash for $165, approximately. extraordinary.

TexPhoto · Jan 5, 2015

That thing you are doing, don't do that. Erasing one picture at a time is bad. This will lead to corrupt cards and data loss.

Dump your photos onto a computer and sort and discard there. Put the cards back in and format. Running out of space on a card? Dump your photos onto a computer, and next time buy larger cards. They are dirt cheap.

Lee Jay said:

The SX60 is capable of extremely sharp shots but there seem to be a lot of bad copies and a lot with intermittently jumpy IS. Some IS systems have apparently cleared up with time. Try it with the IS off on a steady rest or tripod to see if this is the problem you're having.

The SX50 had no such trouble.

What is the IS please Lee Jay? Sorry, sussed it, cheers

Did the 1.6 firmware upgrade (from 1.3)… Now when I go to restore my AFMA numbers via FoCal, the camera is no longer seen. I have tried 2 different computers, using 2 different USB cables, and 3 different apps (FoCal, ShutterCount, EOS Utility) to get it to connect, but no luck.

Anybody else experience anything similar? Anyway to troubleshoot the USB system?

Did the same upgrade. Working fine with my Macs.

From the wording, I'd guess that a similar patent for the lens side is on its way.

Click to expand...

I would hope so. I'd expect metal-on-plastic to have a serious wear problem, because of the extreme difference in material hardness.

+1

Metal has no problem sliding on plastic, but using a existing lens and mount which may already have some damage would certainly scratch the plastic surface, and even new metal lens mounts can get scratched and dinged.

I'd expect to see this on the new mirrorless camera and lenses series as a way of cutting costs. The lens adaptor to EF mounts can then be replaceable if any damage occurs.

tayassu · Jan 4, 2015

Sounds interesting, IF
-the AF is competitive
-the lens has good wide-open IQ over the whole FL spectrum
-it has a VF
-it is not too big.

It's not negligible when you have to put it in your pocket! I was going to buy an S120 but I found it slightly too big for my pocket.

True. Everybody has different sized pockets so negligible to one is too much for another.

Elac2 · Jan 3, 2015

On July 11, of 2013, the Forum admin posted that updated 45 and 90mm tilt-shifts were likely in 2014 based on his source(s).

Has anyone heard ANYTHING about these updates? I am so wanting a 45 TSE updated and constructed like the my 24-TSE M2.

(There had been a post in CR late fall'of 2013 suggesting a 45Mk2 TSE was likely due by late spring of 2014. When no word of this lens surfaced by summer, I hoped it would unveil at Photokina. But no such luck.)

Thanks for any insights.
