Minolta MD 24 F/2.8 review avatar


Test description: Camera Sony A7II (24mpx, full frame) – fixed on the tripod. Targets (buildings) – fixed by gravity power on the distances in more than 200 meters. All shots were made with apertures from fully opened F2.8 and up to F16. ISO-100. Shutter Speed – depends on light (camera A-mode), WB – same for all shots. SteadyShot – OFF. Focus was manually corrected for each shot to exclude focus-shift affecting. Focus point – center of the picture.

Finally, pictures were converted from ARW-files in Capture One with default settings, cropped for 300×200 px elements, combined into diagrams and exported into JPEG-files.

Field curvature control on Minolta MD VFC 24mm f/2.8 is set in the center position

Note: I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.

My conclusion:

I see only one slight difference between Minolta MD VFC 24mm F2.8 and Minolta MD  24mm F2.8 – on F2.8 in the middle position the non-VFC version is little bit better, just in this case – and for me it looks like an DOF-issue, so – can be excluded. I’m sure for 99,999% that both lenses provide the totally identical sharpness and contrast in real photo-sessions. Don’t know how it’s possible – these two lenses have completely different optical design.
