Hopefully a pretty straight forward question but maybe not.
Can the smaller full frame Sigma I-Series lenses support the resolution of Sony’s 61 Mpixel sensor in the new Sony A7CR?
The answer may get complicated by the fact that Sigma now has at least 9 or 10 lenses in the family from 27mm to 90mm but I’m considering pairing these together and wondering if anyone has direct experience with these lenses on the A7RV or even the A7R IV. I can start to do my own testing but wonder I’d anyone already has some background or direct experience here.
Maybe experience on the new A6700 APS-C sensor with 26 Mpixels May also be applicable since the pixel size and pitch of the two sensors I think is the same.
Any, just reaching out to see if any one knows. I couldn’t find any good references on the web yet.
Thank you for your time.
No worries is the answer.
The A7Cr will be about the same as the A7RIV and the A7RV. No problems with any Sigma i series lenses on those bodies. Because the lenses have been designed to optimize rendering while maintaining resolution, some of them are affected at minimum focus distance and maximum aperture by the spherical aberrations that were used to improve rendering. But when the aperture is narrowed or the MFD increased, the lenses become very sharp. I find this especially the case with the 45/2.8 and the 24/3.5, both of which render especially beautifully.
I have six of the i series, I'm thinking about getting a seventh (the 17mm) and I'm taking them with my on-order A7Cr when I travel.
