#SIGMA 18 35 T6I REVIEW UPDATE#
#SIGMA 18 35 T6I REVIEW MANUAL#

If this is repeating on other lenses as well, it seems Sigma has reverse-engineered Canon's DPAF/PDAF protocol perfectly. But even here the focus is always within DOF. On short distance it is amazingly accurate, on longer distances there is some variation. Now after I did AFMA/calibration using the Sigma dock, PDAF is perfect as well. About 90% of my shots are perfectly focused. In Liveview/DPAF mode the lens is now very accurate and realiable. It's such a sharp lens when it's focused correctly. I can't even describe how happy I am right now. Sigma definitely did some major improvements to the AF even if it's not clearly declared in their firmware description. All the above mentioned focus issues, have been solved and my lens became is amazingly accurate now on all AF-points.

2.0 firmware today and it works like a miracle. However through the viewfinder I was only able to get accurate focus only with the center AF-point but even that was terribly inconsistent, every other other AF-point was just way off focus to use. My copy of the lens was OK in liveview though. I was suffering with the AF on my 18-35 ever since I got it back in november 2015. But still don't understand why it took so long and why they don't mention it in the release notes.

The results are nearly undustinguisable from manual focus.įinally Sigma fixed this issue.

#SIGMA 18 35 T6I REVIEW UPDATE#

My new copy had 3cm backfocus (at distance 55cm) before the update and now, after the update, it focuses perfectly. I had copies with severe backfocus (one with 8cm, one with even more). It also works with my Canon M5: Test results And I can confirm that DPAF in Liveview now works great on my 80D with a Sigma 18-35. I bought a Sigma 18-35 as soon as the rumors about the fix were plausible to me. Yes, good news: It seems to be fixed with firmware 2.0 ※ Compatible cameras: EOS 8000D(EOS Rebel T6s, EOS 760D), EOS 80D, EOS 9000D(EOS 77D), EOS Kiss x9i(EOS Rebel T7i, EOS 800D), EOS Kiss x9(EOS Rebel SL2, EOS 200D), EOS Kiss x8i(EOS Rebel T6i, EOS 750D) It corrects the phenomenon that exposure during shooting through the viewfinder or Live View mode becomes unstable.It corrects the phenomenon that abnormal images appear or operation errors occur when Canon's in-camera Lens Aberration Correction function is enabled.It ensures compatibility with Canon's in-camera Lens Aberration Correction function, which enables correction matching the optical characteristics of the attached lens.※.I can't test it for myself because I gave my lens to my cousin for the next 2 months.Ĭan anyone tell me if the inaccurate autofocus in LiveView (+ also in Videomode) with 80D and newer models is finally fixed? The update doesn't mention anything about autofocus but maybe it's also fixed? As in this thread mentioned all 80D are not focusing correctly in LiveView with that lens.įinally a new update has been released for the Sigma 18-35 1.8 ART that seems to enhance the compatibility for newer cameras and also the 80D is listed.
