This is my second copy of this lens. First one, the AF jerked and hunted before locking focus.

When this copy nails the focus, it was at least as sharp or better than what you posted. Trouble is, it often misses focus, especially with the 7D. I tried my daughter's T2i and not much difference. The lens seems to work better on my 5D II but when you focus on anything far away, it back focuses. None of my other lenses have this issue.

I already boxed it back up. I'm just waiting on the shipping label.


Fujifilm X-T3, 16mm f/1.4, 23mm f/1.4, 35mm f/1.4, 56mm f/1.2, 80mm f/2.8 OIS Macro, 100-400mm f/4.5-5.6 OIS, 1.4x TC, Flashpoint R2 Strobes/Flashes

You'll love the 135L Tomme. I'm in the same boat as you. Got the 35L and 135L and just trying to fill the gap with this.

cant wait to get it:D
Yeah, i want to get an 85mm too, as i loved the 50mm on the crop camera i had before!

I do shoot alot wide open and at f2-f2.8, is this lense much sharper then the 85 f1.8 from canon ?

Ive heard that this lense underexpose the image by 1/3 - 2/3 stop, is this true ?

And one more question, is the glass bigger then the 85L, i see that this lense takes a 77mm filter while the 85L does 72mm!

The 85 f/1.8 is a sharp lens wide open and that much better stopped down and the same goes for the Sigma 85 and 85L. I think sharpness can be tossed aside as a factor in the decision making process mainly because they're all sharp.

I haven't had experience with this lens yet but from tests shown, I've seen that it does seem to underexpose a little but so does my 5dii with all my lenses so I just compensate for it while shooting and make sure I shoot RAW.

I'm not sure if it has a bigger glass as I know the 85Lii's front element is HUGE but I also noticed how big this front element is too.

I'm going to the store to see if they have a good copy this weekend and if so then I will pick it up. I really want the 85Lii but between rebuilding my computer and buying lighting gear, I'll be perfectly happy with this in the mean time.

I hear about the distance AF problems more than I'd like to Norbel....I heard the same problem with the 50mm Sigmalux too....My lenses don't exhibit this behavior, neither of the two 50's or the 85....They're (especially the 85) as good or better than their Canon L counterparts....BTW, nice work on your Flickr lately...I follow it closely....Happy New Year!!!

alpharon, cute model :)
Cool blog too, great surf shots there....So...You have the 30/50 and the 85mm?
Just sold my 30 and grabbed a 35L, for no other reason other than I missed the 35L...:)

Thanks thatkatmat! Yup, I've got the Sigma Trinity along with a 135L and 400L. Unfortunately, I just sent my Sigma 50 off for calibration yesterday, so I've only got 2 Sigmas to play with now. I've never had any problems with the 30mm and the 85mm seems to be perfect!

Really appreciate your effort on this test. I have heard numerous information about focus problem when using s50/s85 in Taiwan. I am glad that your test prove that Sigma can do the right things. Sometimes, I am wondering whether these focus problem may due to body difference? We all know that entry level bodies are not able to handle these fast lens completely, especially wide open or large aperture.

Remember I borrowed 1D3 from my friends a few days ago? I could use wide open confidently, even under focus point which was not near the center.

Happy Chinese New Year to you. :)

Well, I tried 2 copies of the Sigma 85 on 3 camera bodies with same result. I wouldn't exactly call the 7D and 5D II entry level bodies either.

Well, 5D2 is an entry level camera body when considering its focus accuracy and ability. It is not in the same league with 7D.
