p.1 #1Sigma 35mm F2 lens on Big Bronco Test plus a Bonus
Im embarrassed to say I forgot the 65mm this morning. Age end of that story
So I wound up going out to BB with my Sigma 35mm and a undisclosed lens till later here
Im processing in C1 and first thing I look for is distortion and this image is completely NOT NOT NOT corrected at all but I want to show it as it is tilting a smidge so let me fix that and the Vignetting . But ill show vignetting later
Let me clean this image series up. But it looks to be a good copy to start , I do have a slight slight softening at F2 in far top left corner compared to right but certainly not enough to care as in one of Freds test someone mentioned it takes a jump from 2.8 to f4 and im seeing it too.
To be very clear this is Guys purchased lens I did not borrow it and its my freaking money on the line . So A I want it to be good but NO ONE is paying me for anything so you get the honest truth or it goes back. I need to justify nothing to no one but love for this to work out. I am NOT crazy about the distortion so outside my temporary one I need to find one quick

So all images fixed that slight tilt, fixed the distortion, base sharpening and equal exposure .
This would be typical in this section of a lens test. Vignetting would be on its own
This is at F2

That distortion was fixed in C1 pick the manufactures profile and adjust the distortion slider until it looks normal. Good news its simple distortion

Once I fixed the little things it looks really good. So you will face some vignetting and distortion. You need to address that like any other lens. Even F2 looks very good , sure a touch soft in corners but not many will shoot wide open where the corners matter. Remember this is a torture test
Lets see 2.8 which im expecting quite good. I also was playing with AF and have to say its pretty quick.

It's weird the A7C is writing "Zeiss Loxia 2/35 lens" in the Exif. Or could be Capture one?

Its doing it with the 65 too Fred.
I mention I forgot my 65 this morning BUT I did not forget my Batis 135. Now you know im nuts so I actually did a center sharpness test on both.
Surprise. Everyone knows you will have a very difficult time trying to beat a Batis 135 on center

I was wondering the same thing. Especially since the auto focus was working so well

AF is working great. Maybe it is C1
Not bothering me as long as the focal length is correct
