I'm getting peculiar issues with the 1DXII with Sigma 35 1.4 Art Lenses.
We used two 1DX II Bodies for a wedding last weekend and came across this weird problem
We get concentric rings around the photos see attached.
originally i thought it was a setting in my camera.... and i couldnt figure it out... even after i reset the camera...
and then it clicked and i realised i was only getting concentric circles when using the Sigma 35 Art 1.4
I then swapped that lens onto another 1DX II body and i got the identical problem also with that body so it seems to be its an issue with the firmware ..
interesting note
- when i downloaded all the files onto our servers and i did a filter for the 35mm 1.4 Art NONE of the photos showed the rings ON the raw images.
- NOT all photos taken with the sigma 35mm showed the Concentric rings on the Body LCD Screen. Only some exhibited this behaviour
- I took OUR the CF card and stuck it in my 5d3 body during the evening of the wedding coverage and noticed when i played back the image ON the 5d3 IT ALSO showed the concentric rings on the LCD Panel ???
- I stuck a 24mm Sigma 1.4 Art on the camera and didnt have issues or the concentric rings
- i could however consistently get the issue with the 2 1DX2 Bodies
Anyone else experienced this ?
over all the camera is a great camera... but this weird concentric circle issue is bizzare
It almost looks as if Canon is "targeting" Sigma. ;D
I am having the same issue as well on my Sigma art 35mm 1.4 and it is on all the pics I am taking with it.
Please let me know if anybody has a fix for it.
Generally speaking, all Canon lenses work flawlessly and much faster than on the original 1DX, in particular the 85 1.2
But I am having difficulties with 3rd party; the sigma shows these circles, while the Tamron 15-30 2.8 is very very slow in achieving focus in video and live view mode, in viewfinder mode it is perfect (better than 1DX) but live view and video mode is a nightmare.
Generally, I can't complain (unless we can't find a resolution for the sigma). The two lenses that drastically improved are the 24-70 f4 (I think mainly because of the in camera lens correction) - focuses very fast and flawlessly and nothing much to fix in post as far as lens correction goes. The second lens is the 85 1.2 - it is like when I moved from 5D III to 1DX, I see that big of a difference. It snaps momentarily and hangs on tight. Both on stills and video. I do run and gun video a lot and this is my preferred lens together with the macro 100 L and both are happy with the new body so I am happy too. It is the main reason I didn't go for the C100.
I will have a chance to put it in real world only in two weeks and will see how good it is when I exaggerate by shooting at 1.4 on the 85 (I shoot mainly at 2.0 but for fun I will try singing faces at 1.4 and see).
