Zeiss 35/2.8 and Sony 24-70/2.8 GM comparisons.

Here are more comparison crops for you to check out, this time it’s between the Sony 24-70mm F/2.8 GM, and the Sony Zeiss 35mm F/2.8; which is a good little lens (reviewed here), but is it as sharp as a zoom lens?  If you aren’t interested in reading the whole post, I’ll save you some time; the zoom is sharper for the most part all the way around!

Sony A7R used for test images.

Sony Zeiss 35/2.8 sets are along the top, and Sony 24-70/2.8 GM sets are on the bottom of image.

Here is the whole test scene and where the crops are taken from.


left side, center, and right side

The prime is slightly ahead of the zoom, mostly noticeable in the left side crop.


The left side of the zoom is a little soft, but other areas are just as sharp or sharper than the prime.


The zoom sharpens up all around at F/5.6, but the prime is maxed out at F/4, and gets no better until F/11 along the sides.


About the same results here as the F/5.6 crops.  Click pictures to enlarge.


The zoom looks sharper all the way around at F/11; a little surprising.

The Sony 24-70mm F/2.8 GM seems to have slightly better contrast at all apertures, and is noticeably sharper at small apertures.

That’s it for this mind blowing comp!
