I am looking into a fast 85 but really cant decide, there is also the zeiss f1.4 to consider which looks soooo sweet. I was also if anyone has used any of these lenses with a teleconverter and what sort of results you get
say an 85mm with tc stopped down to f2 vs the 135 f2 native?

I have found my "hit rate" with f/1.4- f/2 lenses (50 f/1.4 and 135 f/2) improves radically if I shoot using AI focus and shot at 8 fps on the MkIV, particularly when shooting people handheld. Just that tiny rocking on your feet is enough to shift focus from the eyes to somewhere useless.

I think it's more than just front/back movement, though that's an important point. I get the feeling that one shot AF quits a split second too soon with fast primes, or at least with Sigma fast primes. AI Servo keeps trying even if you and the subject are stationary. I get a higher hit rate if I use AI Servo and wait to fire until the AF has settled.

I personally like the way the focus ring feels on the 85L when I shoot video, it's alot easier to keep someone in focus with that as opposed to the 135L.

The teleconverter takes away a stop -- so you get f/2 wide open with the teleconverter.  Check compatibility -- I don't think the teleconverter is compatible with the 85.

the kenko one works with everything i think with the 1.2 it will be 1.7 wide open so f2 will be stopped down half a stop which should sharpen thing up a bit. I should try borrow these off friends and try it out :)

Nice to see some photos in the replies as examples of what the Sigma (and Samyang) can do.

I found this review on a blog of a wedding/portrait/commercial photographer who used the canon 85mm 1.2L and then used the Sigma 85mm 1.4 that is pretty interesting.

http://hofferphotography.com/2010/11/16/my-sigma-85-f1-4-vs-canon-85l-review/

I liked what he said at the end about how we "need to throw aside the idea that the most expensive thing is best."

One thing I like better about the Sigma 85/1.4 lens is that its aperture stays circular all the way to f/2, & almost circular all the way to f/2.8.

The Canon 85/1.2 II is already non-circular by f/1.6 & pretty offensive (to my eye) by f/1.8. OOF highlights just don't look very good anymore as they have distinct shape to them.

Sigma has 9 aperture blades; Canon has 8. I'm surprised this isn't mentioned more often.

In my side-by-side tests, though, it appeared to me that at any given f-stop, the Canon lens had a wider actual opening than the Sigma (looking thru the front element). This could explain the slightly underexposed images from the Sigma as well as the lower amounts of background blur of the Sigma as opposed to the Canon.

for anyone that hasn't alreay seen the review :P

does anyone know if this AF issue with the sigma is a continuing thing or if its been resolved in newer releases?

such a hard choice

canon 85 f1.2L II - most expensive
Zeiss 85 f1.4 MF only - higher middle cost
sigma 85 1.4 - lower middle cost
canon 85 1.8 - lowest cost

the sigma is looking like a very attractive option

YMMV but I find that among all the 85mm primes, the color rendition, bokeh, and sharpness of the 85L 1.2L II are magical.  Here's an example taken using my 35mm film camera  CANON EOS 1V-HS with KODAK EKTAR 100 and my baby 85mm 1.2L II -- scanned by an EPSON PERFECTION V700   ;D

I'm a user of the sigma. It is superb and gets the thumbs up from me.

Shot wide open at f/1.4 and still sharp.

FWIW, TDP reviews seem to have a lot of problems AF on Sigma lenses (perhaps more surprisingly no problems with AF on Canon's lenses which autofocus perfectly out of the box). They are good reviews, but if they are your only source of information, you will come home with the impression that you should never (or almost never) buy non-Canon lenses.

I needed to micro adjust mine (+6) but once I did that, it is pretty consistent (and doesn't seem to change with different apertures)

Yeah my Sigma also needed a +3 microadjustment but, then again, so did my Canon 35L.

After that, center point focus was dead on. It consistently hit my test chart at a 45º angle at the right spot.

But when using the right-most AF point on my 5DMkII, focus was rather erratic. Dead-on, back-focused, front-focused, you name it.

However, same performance with my Canon 35L, so I doubt the Sigma lens is at fault here and, rather, it's the low precision of the outer AF points on the 5DMkII that render it nearly impossible to nail focus with such shallow DOF.

I only ever use center point. I dont trust the others. After recomposing I refocus manually.

That's the kind of thing I was getting at. I've had some issues with the Canon  50mm f/1.4 focusing accurately at longer distances (I ended up using manual focus and live view -- thankfully subject was very still) but it works like charm most of the time.

What strikes me about TDP is not just the issues he has with Sigma, but the fact that he never has any trouble with AF on Canon lenses.

Am the same, I only use the center AF point with my 5D mkII and it has been working very well.  The only time it struggle a bit is when I have a moving subject in Servo mode ... but I keep getting told the 5D was not designed for that  ;) ... so this is why we need a 1DX!
1DX, 24mm f1.4L II, 35mm f1.4L, 50mm f1.2L, 85mm f1.2L II, 135mm f2L, 24-70mm f2.8L II, 70-200mm f2.8L IS II :  D800, D4, and a whole bunch of Nikon lenses
