I see many happy "Kegma" owners on this thread, love to see all the nice images. Just sold my Sigma 50EX and I'm very interested to try the "Kegma". There is one more thing that bothers me even more than front/back focusing, it's the focus shift that the 50EX is known for. Is there a similar problem with the 85EX? I know it is not really a problem when shooting wide open but I like to shoot closeups and the 50EX was just killing me at f/4-8, it just didn't work without a Live View or constant use of the DoF preview button and focusing manually. Any thoughts?

I was contemplating getting the 85L to use on my 40D, but now I am SERIOUSLY considering this baby instead and putting the cash I save towards upgrading to the 7D! I shoot solely with a Sigma 30/1.4 EX DC HSM and couldn't be happier with choosing it over the Canon. Thanks for all the posts! You folks help making decisions so much easier seeing these beauties in action :)

No notice of focus shift on my lens, although I've never had a lens that did it so not sure what to look for. The AF motor on mine sounds attrocious though, like there is grit grinding around in there, but I don't think that's too uncommon unfortunately.

With some lenses (like Sigma 50EX) the focus plane moves when you change the aperture and you can see it only when you press the DoF preview button or after you take the picture and see the result. It's not a problem when you shoot "wide open", the aperture stays the same and the focus plane doesn't move. This effect is mostly noticeable at shortest focusing distances while using small aperture (f/8 for example).

Took 125 pictures of my daughter's volleyball practice and only had two that missed focus. Pretty impressive for the first time out.

I don't have anything up close at f8, but 1 meter away at f4 there is zero shift.....Was looking at all my shots....I usually shoot the 85 at 1.4, but of course the longer I have it, the more boring that gets and I start using it as it's supposed to be used...:)


Not this one....this is wide open....

Went to a zoo/theme park yesterday. A lot of fun! Having become a shutterbug has made me a much better parent. Now I love to take my kids out to places with photo-ops.

Here is my story with the problems of this lens.

When I first got the sigma85 i noticed that it sufferd from front focusing. I sent it to Sigma service center for calibration. When I got the lens back, it still had problems with front focus!

I tried to correct the problem by using the micro focus adjustment on my 5D Mark II. But it was no good, because the focus problem varied on different distances. I sent the sigma85 back to the service center (again), and when I got it back the 2nd time it was still no good.

I was very frustrated, and then I sent my 5D Mark II to service at Canon, to see if there was something wrong with my camera. They did a full check on the auto focus, adjusted and tweaked it a little bit and sent it back to me. I tried the camera with the sigma85 and the lens was still no good. Front focusing was still a big issue.

BUT, now when I tried to use the micro focus adjustment it worked well on all distances!! It no longer matterd how far or how close i was to the subject. Micro focus gives me perfect focus all the time.

So now I have a front focusing Sigma 85 that works great thanks to micro focus adjustment. :) Fine with me!

So I was going to get a 2nd Einstein today but I'm now thinking about ordering this instead to close the gap between the 35L and 135L. I'm just wondering which one I'll put to use more until I can afford the other which would be just a couple months. I think this is in the lead for now that way I can practice and perfect lighting with one strobe instead of multiple.

I've been doing quite a lot of work lately with this lens since I got it. At first the learning curve of f1.4 on a medium tele is pretty steep, I shot it on a wedding I did about a week after I bought it. Not such a good idea. But I still got my money shots.

It's been a few months since I've purchased this lens. I've used it for documentary work like weddings and events.

This lens together with the Canon 35L is my most used lenses on the 5dmkii. I shot the Thaipusam festival here in Singapore recently with it, here are a couple of pictures.

Processed in LR3 and sharpened with Nik Sharpener.

But I must admit I use the 85 focal length very sparingly as I find it provides a lot of subject isolation, hence it focuses a lot on specifics like a particular object or person.

When I do use it however, it's absolutely magical.
