Full frame section next.
Full frame results using the Sony A900 below.
Check out the differences when using a film or full frame camera below. I’m only pointing out the noticeable issues as compared to the APS-C bodies, so if I don’t show it here, the results are not significantly different enough to warrant posting an additional set of images in this section.
Light fall-off
Light fall-off is definitely stronger with full frame coverage. I see moderate to heavy levels at F/2, however, by closing the aperture one stop, things clear up nicely. Regular filters cause additional light fall-off, although almost unnoticeable unless compared side-by-side.
Full image below illustrating light fall-off from A900.
This full scene shows actual-use light fall-off. It’s really not too noticeable, and certainly not distracting in my opinion. This bright daylight scene would normally be shot around F/5.6, where everything would be in focus, and light fall-off would be completely gone. Data for the image is; F/2, 5000sec, ISO 200.
Lens flare/ghosting samples.
Noticeable above is the slightly different ghosting artifacts with full frame coverage. This stuff is visible in the viewfinder, so just pay attention, although there’s nothing you can do when the sun or other bright light is inside the image. All samples above show the entire image, and are not cropped.
Color fringing crops below.
Here are some samples of axial color fringing, which goes away as you stop down. These crops are from the A700, I put them down here in the full frame section because I’m too lazy to make a spot in the top section, plus it looks the same on the A900. The two 100% crops were taken from the center of the image, and shows some moderate purple fringing, fortunately, it almost goes away just one stop down.
Full frame corner samples next.
The full frame corners are soft at F/2-2.8, but sharpen up nicely at F/5.6, as a side note; these crops are the same as I used in the comparison review. Not shown here are the sharp mid-to-outer areas of the frame, fortunately, I have crops showing those areas which can be seen in the comparison review. I threw in a couple of center crops at the bottom row for comparison. Crops taken from the last 300 pixels of the lower left corner. Exposure differences are from light fall-off.
Distortion next
I see mild to moderate barrel distortion with full frame coverage. Although very slightly wave-type, it can be corrected well in post processing.
Coma results below.
Coma is somewhat heavy in the corners at F/2, but diminishes to nothing by F/5.6. This lens seems to have better control of coma than the Minolta 28mm F/2 lens.

Overall, I’m very impressed with the old Minolta AF 35mm F/2 lens, it’s sharp in the centers at F/2, with the corners sharpening up at F/5.6. I also like the way the mid-to-outer image areas are sharp, making use on an APS-C camera that much better. Light fall-off is slightly noticeable on full frame when used at F/2, but APS-C users avoid this issue. Distortion is mild to moderate, again, depending on sensor size. Ghosting is poor by today’s standards, as is coma, but that stuff is manageable. It’s a shame Sony hasn’t re-issued this lens with updated coating like they did with the 35mm F/1.4. In fact, if you go here, you can see the 35mm F/2 performs better all the way around in sharpness, although you do miss an extra stop of light.
The Minolta AF 35mm F/2 is the best of the wide to normal primes available for your Sony camera (or Minolta) in my opinion, although the 28mm F/2 performs about the same, I guess it all depends on what your favorite focal length is.
APS-C users; has about the same coverage as a 50mm lens on a full frame camera, and coma and light fall-off is almost avoided due to the crop factor.
