Comparison of lenses Minolta MD 35mm 1:1.8, Minolta MD 35mm 1:2.8 and Sony FE 35mm 1:2.8 ZA
This comparison is correct only for conditions and equipment used for tests. Test results can be differ if any element is changed.
And Sony Carl Zeiss Sonnar T* 35mm f/2.8 ZA – as guest in additional comparison.
Test description: Camera Sony A7II (24mpx, full frame) was fixed on the tripod and managed remotely with computer display as a viewfinder. Targets (buildings) were fixed by gravity power on the distances in more than 200 meters. All shots were made with apertures from fully opened and up to F11. ISO-100. Shutter Speed – depends on light (camera A-mode). SteadyShot – OFF. Focus was manually corrected for each shot to exclude focus-shift. For excluding of any possible field curvatures affects – focus was set on the red rectangle for every of positions – center, middle, corner (see scene previews).
Finally, pictures were converted from ARW-files in Capture One with default settings, and with little WB correction (because weather changes). 300×200 px elements were cropped (100% crops), combined into diagrams and exported into JPEG-files.
As you know, Minolta’s N-MD series lenses haven’t “half-click” after the first aperture position, so I stop ring in the middle position, but it’s impossible to set it precisely, so, if you see that a picture taken, for example, with N-MD 35mm f/1.8 on aperture 2.0 – it means that picture was taken on aperture set in the middle position between 1.8 and 2.8. Same for N-MD 35mm f/2.8 with photo taken on f3.5.
- Sunlight has been changed during the session. A lot of times, every 2 minutes.
- I am just a man, I do not pretend that in all cases my focus settings were absolutely accurate. But I aspired to it.

From the sharpness point of view, Minolta MD 35mm F2.8 … is better than faster and much expensive Minolta MD 35mm F1.8 even wide opened from F2.8 and up to F4.0. Yes, the difference can be seen only with microscope, but it presented. After F4.0 both lenses are the same. On the other hand, Minolta MD 35mm F1.8 has F1.8 but Minolta MD 35mm F2.8 doesn’t.
That’s why for me it’s impossible to choose the best 35mm Minolta’s – both of them are good for different tasks.
About Sony Carl Zeiss Sonnar T* 35mm f/2.8 ZA:
My friend gave me Sony Carl Zeiss 35mm F2.8 for quick photo-session of buildings – just with only one focus-point in the center.
I did not have enough time to work and therefore deviations are possible. In anyway, I am pretty sure – overall result are close to the true picture of these lenses behavior.

My simple conclusion:
Sony Carl Zeiss Sonnar T* 35mm f/2.8 ZA can takes the same pictures as Minolta MD 35mm f/2.8. Not more.
