I've been under the impression that the sensor is shared among the t2i, t3i, t4i, t5i, 60d, and 7d.  Am I wrong?  Yes they are all 18mp and the dimensions are the same in regards to pixel... but I'm hearing otherwise... and I don't want to go on spewing misinformation...

The .jpg file size varies between the t2i and the others... but who shoots in jpg.  Is the raw image basically the same save for that stupid filter the 7D and 60D share (and I don't believe anyone likes). 

That's about it... thanks for setting me on the right path.

Me...I shoot in JPEG. Do you have to shoot RAW?

You don't have to shoot in raw... but I have had some images saved because I shot in raw. But to each his own.

But as discussed... sometimes the a(whatever) filter can have a deliterious effect on the image, so I don't want the camera dictating what my image looks like.

So in this instance... if you shoot in raw with both a t2i and a 7d... is it the same basic image?  And there inlies the puzzle.

I'm not a wide angle guy, but I would agree with everything nuero said.  If I were to make an addition, I might consider a rokinon 16mm.  The wide angle lens itself well to not having auto focus, and if you stop down, the image quality is very good.  But that is just an alternative... which Mau afford you to get another lens on top of that one.

The people at Imaging Resource who did the review have posted a Flickr set with real-life photos: https://www.flickr.com/photos/97470426@N06/13719437215/in/set-72157643654332185/. They used the 50mm Art on a 1Ds Mk III. I'm no bokeh expert, but the out-of-focus highlights look fantastic to me. Anyone want to weigh in on these?

I thought the pictures of the musicians were pretty boring.  But the lens does look sharp and in the helmet and bike photos... the lens looks like a winner.

Camera will focus on subject eye, by pressing down Center Button( in my case). By the way, the eye AF is VERY-VERY accurate. Even at wide open aperture.

Got it, thanks!

I have no clue what I'm looking at.  Was he focusing on his computer screen?  Why not do something in 3 dimensions... heck a ruler... but ok.  That is a cool feature... though I think the demonstration is lost on me.

The only ruler with eyes I could find online. A bit creepy if you ask me...

And here I thought that the camera tracked where your eye was looking and then focused there. Silly me.

First photo is 85L II @ f1.6, something that 135L can't match ;) 135L would be my 2nd choice for portrait on Canon gear.

Totally agree with the fact that 85L is THE portrait lens. It's just something I want, but don't particularly need (looking at my most-used FL histograms, at least). :)
By the way, when you say 'eye detection' does it mean it detects the subject's eye, or is it eye-controlled focus like the Elan 7NE/EOS 3?

To be exact, this feature calls "Eye AF", in "Custom Key Setting". You need to assign this "Eye AF" to one of the button on your camera. In my case, I assigned to Center Button.

Camera will focus on subject eye, by pressing down Center Button( in my case). By the way, the eye AF is VERY-VERY accurate. Even at wide open aperture.

You could always sell the 85mm with its terrible CA and pick up a 100mm f/2. Then pick up the 50mm ART. You didn't mention which body you have, but the 100mm f/2 gets the same dxo overall score on a 6D and 5D MKIII as the 135mm albeit a shorter focal length.

I must be blind to the purple and green fringing on the 85mm... I swear in the year and change that I owned it... I didn't see many... if any examples of CA.  So weird.  And I know when and where it shows up... and I used it in a ton of different settings...

I recently shoot quite a bit with my A7r + Zeiss FE 55mm(second photo). This camera has "eye-detection" feature, therefore, composing the shot is very easy. I think we all know how fun it is to compose the shot with big aperture lenses ;D

I need to find someone to sell me the 85L for $1500.  I'm jealous.

Hi all
So my wife and I were walking in the park and she spots this hummingbird and points it to me. I have never seen one before, and got quite excited and worked up. The results were quite dismal (the best effort is below), so I am not even going to ask what I did wrong. But let's say this situation arises again, what should I do to ensure at least optimal results. I had a 135mm L attached to my 5dIII, ISO 160 (was set on Auto), f/8, 1/125 (was set on Av, forgot to change it in the haste). Thanks in advance.
Welcome to the world of Birds In Flight photography!

From what I can see, you got a pretty good shot there. The only thing I might say is a little cropping might be in order (unless you've already done that to excess...) to make the Hummingbird more prominent.

Hummingbirds take patience to photograph, and even so, they move very quickly and seem to never be in the right place. I often photograph them at a local refuge, and I'll set up my tripod with a 100-400 lens (set at 400, usually) only 8-12 feet from the flowers they are attracted to. This is to nearly fill the frame with the tiny bird. And for every keeper, I'll have a dozen or several dozen where I got bird butt, half a bird, no bird, blurry bird, etc.

If you can crop it a bit, do that and frame it. It's a nice photograph!

Do you spray and pray.  I think I would with ai servo...  provided I didn't do the of camera flash setup.

If money is no obstacle, buy 135mm L now, and at the end of the year to buy Sigma 50mm Art with discounted price.

Agreed... but if you buy it used, you might not lose any money.  I bought it for $650ish... and sold it $840ish... That is obviously atypical... but if you buy it for $850... you can probably sell it for $850.

JD, you live in some parallel universe (read: you are incredibly resourceful with second hand lens buying and selling).
Wish I had your skills in getting me a 35L...  :)

I had a chance to buy a 35L for $900... but the new 35 art just came out and I wasn't sure what I wanted to do.  I regret that one... Then last December I had a chance at a 35 art for $700... and I didn't pull the trigger.  There's something about the 35's that just cause me waffle.

If you don't get it this time you will know you really didn't want it :)

I'd rather have it new for 700 than 679 as a refurb... so no.... again.

"Still a nice memory recorded. "

When photographers (and I am not saying that you are one just using your post as an example) say "nice memory" I want to drive to their house and throw a Nikon through their window... Detest that phrase..

Just saying is all...

also nice snapshot for 1/125

John

funny....i kinda like the phrase. 8)

I agree, and I'll take it one step further: in the vast majority of cases, "nice memory" photos will far outlast  "art" photos.  All but a handful of "art" photos will die soon after the photographer, if not before, while memory photos live on.  Abstract photos, in particular, have a very short shelf-life.  Think of photos of significant people or events of the 1800's: in most cases, the image quality is crap, and the posed shots are often laughable by today's standards.  It's their historic value that breathes life into them. 

There are certainly a few art photos that still give me a "wow" reaction, but I'll generally take a good (not great) memory photo over "art," so long as it comes with a good story.

I try to take "art" photos, as does nearly every photographer.  I am well-aware, however, that these photos are primarily for my own enjoyment, and there may be no one else who finds them the least bit interesting.

Is "art" code for "dick pics"... because yes... I agree 100% with your above statement.

50mm 1.4 < 135L 2.0 for most portraits.

50mm > 135L for everything else.

I'd say the 135L is better for indoor sports photography... and you could definitely get some quality images outdoors as well... but I guess we can see how the AF system holds up. 

Actually for outdoor sports... I wouldn't want to get too close and the 50 would be too close for comfort... so... but that is a small segment of your argument... and I agree... mostly... except for the canon 50's which I don't care for wide open... well... not the L... but I haven't used that one.

I'd probably start by buying a hummingbird feeder.  I know that's cheating... but it is probably easier to entice them to come to you rather than you go and find them.  Then when I have regulars... I would set up a dual off camera flash using hss and obviously flash modifiers... and I'd shoot with the 135L... or if they fly away if you get to close, a 200 f/2.8, and shoot at 1/2500 which I believe there would still be a little bit of blur, or 1/6000 for no blur... but I think you want blur... and an aperture of f/4.  Because you are running ettl through the satellite flashes... you can shoot at f/8 and they will compensate... which is a real plus.  Iso... 160.
