The Digital Picture has the crops up for comparison:
http://www.the-digital-picture.com/News/News-Post.aspx?News=14614

It looks very good to me, and I'm pleased to see how sharp it is compared to the other lenses in the range. It holds its own against the 16-35 f/4 IS, with less distortion, is better at 24mm than the 24-70 f/2.8 II, kills the Sigma 12-24 II, and stopped down, is as sharper or sharper than all but the TS-E 17 and 24II lenses. It sure makes me feel better about the money spent.

One of the key points on even Sigma's site promoting the Art series is how the lenses can be updated with the dock.

The 35mm Art had the firmware updated within six months of release, and I was lucky to get one of these that continues to amaze me with its IQ and AF.

I returned a 50mm Art with erratic AF, believing that a firmware update was soon to come. That was about a year ago...

So, please speculate, why has Sigma not addressed Canon (and even some Nikon) mount AF issues on the 50mm Art?

Could it be that the only people in the world having troubles are those posting here? I know I've read several otherwise great reviews that, as a footnote, mention "slow" AF or "not always accurate" AF.

What's going on???

Hi there, please can I get your help.

I have the Tilt Shift 90mm which I use for Product and Still Life photography in a studio. I love the sharpness and clarity of the lens, and so far I haven't really used the tilt function that often.

A few weeks back I dropped the lens on my camera body, 6D, from a height of about 2 feet onto the carpet and the shift had shifted by 8 degrees. It may have hit a piece of metal lying around.
I have only started to use the lens again recently.

I generally shoot Jewellery as part of still life set up with studio lighting; so on a table, I might put the Jewellery on a tile, or fabric.
If I fill the frame with the shot and focus a third of the way up (perhaps focussing on a specific Jewel), without tilting or shifting I am noticing that the top edges of the image, are a little soft, at f16. This is only really noticeable at 1:1 preview in Lightroom. If I focus nearer the top third, the bottom of the image is slightly soft at 1:1.

The edges are sharper at f22, naturally.

My question is, is this normal for this lens with the conditions that I work in, and am I pixel peeping, expecting too much, or should the lens not display softness around the edges at f11 - f 18, 20, when doing this kind of tabletop studio work? Am I focussing on the right point?

I did not notice this before it was dropped, but maybe I wasn't looking for it, plus I was cropping the edges of the frame, to get the best composition. I have checked previous images and one is slightly soft around the top edge.

thank you for your help in advance.

Hi!

I was shooting some video yesterday and noticed some unusual flickering of some sort I think..

Here's a video of the actual problem: https://www.youtube.com/watch?v=cnU4SB9t5E4

First I thought it's just some problems with the lcd screen but later I noticed it continues to show in the record itself (as seen in the video).

It does not appear when shooting stills in LiveView mode. Also worth mentioning that I tried it with all my lenses and it seemed to be equally bad with every lens.

Shutter speed seems to have something to do with it. Lowering shutter speed below 100 seems to make it disappear (you can see me swithcing shutter speed in the video).

Anyone know what might be causing this or has anyone noticed similar problems?

Thanks!
-Dan

Dear Canon,
why can't you add IS to a new 400/5.6L in your setup, 10000' of bird/action photographers would buy a lightweight, top-quality lens of this caliber the first week out on the market!?
High-ISO and better cameras is perfect for such a lens!
OR you could look up in your museum the even older 400/4.5 and remake that, that used to be a nice lens in the old FD-era

Back to the drawing-table NOW!

Hello fellow Canon photogs

So I've been itching to upgrade to a new body. I've always been told when you upgrade, always get new glass. Right now I'm looking at possibly a good deal on a 7D, which is one of the models I've been looking at. Is this a worthwhile upgrade?

TIA

I have recently bought myself a brand new Eos 6d and am loving it but noticed that whatever I input as time for the metering timer of the camera it always turns of after 4 seconds...
Have gone over the manual to see if this is caused by some conflicting settings, but couldn't find anything.

And eventhough it's no biggie at all, the camera works perfectly for the rest, I am just wondering if any other 6d-user has experienced this and if it could maybe be the beginning of more trouble (computers you know)? ???

Hello guys. I take some intraoral photographs in the dental clinic using 70d and 100 2.8L. The combo works well, but sometimes I don't like the colors of the mouth tissues, even if shoot RAW. Once in a while I read very nice reviews about some other macro lenses (e.g., Voigtlander SL 125 2.5, Schneider Makro-Symmar 90mm 4.5, Leica R 100 2.8 APO) and I'm wondering if these lenses will give me some better image quality and color rendition?

All pictures I take are manual only, Canon Macro flash, ISO 100, shutter speed 1/100-1/150 sec and the widest aperture is 22 (I typically use aperture 32). Considering these parameters, would any of the above mentioned lenses give me any advantage over Canon 100L?

Another question is does anyone know if I cut a gray card to a small size to fit into the mouth, would I be able to more or less correctly adjust colors in LR?

Thank you!

I've never done any underwater photography, but I would imagine that the loss of light as one moves into deeper waters would limit things a lot. Lo and behold, I ran across this nifty housing made for the Canon 600EX-RT while browsing Adorama's website. This has got to be real cool for those that work underwater, and since Canon's flash works via radio it must open up all kinds of possibilities!

Has anyone here done any underwater flash photography using speedlites? I'd love to see some photos!

Here's a link to the housing:

I haven't had a lot of time to really intensively use my 7D II yet, but I've already noticed a couple of quirks that are contrary to what I understand to be true both in forums like this and also in the manual. I have 2 5D IIIs and have previously used 3 1st generation 7ds. All of those bodies have allowed me to select AF focus points using the rear dial (vertical movement), the joystick (omn-idirectional), or the top dial (horiontal). The manual for the 7DII states that such should be true of this body as well (page 81 of the manual). That's what confounds me. When I spin the top dial to select points (something I do in my sleep with the other bodies), rather than move the AF points, the camera simply cycles through the AF modes, which I find extremely frustrating. Is this how the camera works for everyone else? Am I misreading the manual when it says that the top dial should change the horizontal focus points? Is this a flaw with my body?

Secondly, I have the Sigma 300-800 f5.6. I also bought the just released TC-1401 Sigma 1.4 teleconverter to use with the lens on the 7DII. This combination should effectively provide me with f8 and should allow autofocusing using group G and center AF point. (page 86 of manual) When mounted, the camera registers f8, but regardless of which AF mode or zone selected, nothing initiates autofocus with this combination. Again, is there a trick I'm missing? Am I not understanding the manual? Does anyone know about any incompatibilities between this lens+tele combo and the camera I'm not aware of?

I appreciate any thoughts, suggestions, corrections to my understanding, or otherwise helpful comments. Thanks.

Hi.

I have a question about how to use the 600ex rt for analoge photography. I have tried to read the manual, but I am a bit confused.

What I have done so far on my Mamiya RZ 67 pro ii is to trigger the flashes With the PW Plus X, and I lightmeter it With my Sekonic 758 Cine With the PW chip. This Works well, and is all manual..

However, I have heard that it is possible to get the flash to do some Limited Reading done for me... Is it possible to have the flash in the coldshoe on my Hasselblad 500cm (With the PC sync cord to my Hasselblad leaf shutter lenses), or other times, the PW in the coldshoe Connected to the lens, thus lightmetering/getting a read on the correct amount of light before firing off camera? A friend of mine who uses Nikon tells me he can put in his ISO, Aperture, and Focal range into the flash, so it reads the scene, and gives the right amount of light..

A) is this possible With my canon flashes (600ex rt)?
B) how fast can I sync the canon flashes, given that my hasselblad has max shutterspeed of 1/500 second?

Thank you,

Gerhard.

I'm wondering if the Wondapaner filter system will work with the new Canon ef 11-24mm f4 L lens?
It uses the largest diameter filters currently available. They are like dinner plates, nearly as big as the front element on a 400mm f2.8 LIS (I know because I currently have both). I use my Wondapanner with my TSE 17L and it's possible to achieve max shift in all directions and be vignette free. It's great to be able to use a polariser or a 3 or a 5 stop ND. The ND isn't very neutral but it's useful when an exposure blend is required to get the right shutter speeds. I find on the TSE-17L that I can only use one filter at a time with full shift. But if I stack 2 filters, I loose a few mm of shift. The flare with these filters is pretty bad, far worse than the naked lens element. Which leads me to think that these 145mm filters are not very well coated compared to the native lens...and one has to ask why they are SO expensive as a result.

PhotographyFirst · Mar 4, 2015

I've been looking at many sample photos from the 11-24 at 11mm. So far I have spotted some copies with poor centering at 11mm. At $3000, you should be demanding perfect performance.

Here is one example. If I am incorrect about my observation, please let me know. Check the lower corners. On a 5Ds, this is going to be way worse.

https://www.flickr.com/photos/29823753@N02/16030615343/sizes/o/

If you need help with checking with centering, I have a 16-35L guide in the education section of my website which shows you how. It applies to all lenses.

ScottyP · Mar 3, 2015

Sigma is hinting at upcoming "unique" lens, risky and odd like their 18-35 f/1.8.

Sigma Rumors is thinking it may be a trifocal lens. http://sigma-rumors.com/2015/03/sigma-upcoming-very-unique-lens-thoughts/

I guess the idea is it could be optically simpler and would not have to be good at every FL, just the 3 of them?

<strong>(Reuters) – Canon Inc (<span id="symbol_7751.T_0">7751.T</span>)</strong> Chief Executive Fujio Mitarai said his company had the funds and willingness for more acquisitions this year after a planned 23.6 billion Swedish crown ($2.8 billion) takeover of network video surveillance leader Axis AB (<span id="symbol_AXIS.ST_1">AXIS.ST</span>).</p>
<p>Mitarai has been leading efforts to find higher-growth businesses to complement Canon’s imaging expertise, and help the Japanese company expand beyond a camera market under attack from smartphones sporting competitive image-capturing capabilities.</p>
<p>Canon’s offer for Axis represented a premium of nearly 50 percent to the stock price before the announcement, a price some analysts said was high enough to ward off rival bids.</p>
<p>“If you buy a cheap company, you need to spend on drastic restructuring,” Mitarai told Reuters in an interview on Tuesday. “I only buy good companies, even if they’re expensive.”</p>
<p>Canon, which earned over 80 percent of revenue overseas in 2014, said it would pay for its biggest purchase ever in cash. It held 845 billion yen ($7.05 billion) in cash and cash equivalents at the end of December.</p>

Its not new and nobody says its perfect, but I needed a fast 50mm and least expected to end up ordering this lens. I felt I was taking a bit of a chance, considering various adverse comments on the web, but wow...I am enormously impressed. I wrote an initial review here (http://thephotofundamentalist.com/?p=1605) and will follow it up, but I have seen enough to realise that this is one of the few modern character lenses. It is far from perfect. It is not an ideal all-rounder IMHO, due to weight, size and cost (as well as some optical compromises), but as a 'people lens' it is absolutely phenomenal.

Looks like a lot of the harshest criticism is down to user issues like focus calibration, focus accuracy and movement (its f1.2) as well as some design compromises, but oh boy am I glad this lens is NOT one of the many perfect lenses we see nowadays. That would kill it as a portraits lens IMHO. So glad I bought one before there is a risk of a new Mk II version with 'improvements' LOL.

I am itching to use this lens for serious work. Alongside the 85 f1.2 L II... for portraits...well, what more could you want?

I will admit that I have been very frustrated by Canon's inability to produce bodies with more dynamic range, but lenses like this remind me of why I have not left the Canon stable.

We’re told that the next L lens from Canon will be a prime and it will be coming in late summer/early fall of this year. While the source wasn’t sure what lens was coming for sure, they did let us know that prototypes for a replacement of the 35L were out there. This has been a long rumoured lens for replacement, with multiple patents for the optical formula throughout the years.</p>
<p>For the moment, lens production capacity is what will dictate when new lenses are announced. The brand new EF 100-400mm f/4.5-5.6L IS II has been out of stock around the globe at major retailers for a long while now, so I’m sure that has priority for Canon. As well as the brand new and highly touted EF 11-24mm f/4L.</p>
<p>The only other primes I’ve had multiple discussions about are replacements for the EF 200 f/2L IS and EF 800 f/5.6L IS. Just like the 35L however, those mentions have been around for years. Interestingly, there hasn’t been talk of new TS-E lenses in a long time.</p>
<p>Outside of that, we’re still waiting on a new non L 50mm lens as well as a non L/non DO 70-300 replacement.</p>

Anybody know if there are any plans for a firmware update to address the focusing issues for the 7D Mark II? I recently upgraded and my images are just ok. Far from tack sharp. It seems Canon has sacrificed some image quality for speed :-\ I am trying to figure out if I want to sell and get the 5D Mark III or hold out for a firmware update. Kinda Bummed out as I waited so long for this camera.

Thanks!

The flood of reviews for the brand new Canon EF 11-24mm f/4L are starting to come in. I think the theme of all the reviews is going to be the same. “Yes, it costs a lot, but it’s awesome”. I’m still waiting to receive mine, and watching other people shoot with it is not a good substitute while I wait.</p>
<p>PetaPixel is next with their review of the lens and it includes a lot of sample images.</p>
<blockquote><p>“The Canon EF 11-24mm f/4L USM is heavy and bulky. It is also thrice as costly as the Sigma, which offers slightly narrower focal length and less brightness. However, if image quality (in terms of distortion and sharpness) and flare control is important to you, then there is really no contest between the two lenses. The Canon EF 11-24mm f/4L USM is an outstanding performer in the rarefied group of ultra-wide SLR zoom lenses, by itself or compared to other super wide zooms.”</p></blockquote>
