Minolta MD 28mm 1:2.0 vs MD 28mm 1:2.8(7×7) vs MD 28mm 1:2.8(5×5) vs MD 28mm 1:3.5 – comparison (v1)
Minolta MD 28mm lenses comparison:
- Minolta MD 28mm 1:2.0 MD III
- Minolta MD 28mm 1:2.8 (7 elements 7 groups) MD III
- Minolta MD 28mm 1:2.8 (5 elements 5 groups) MD III
- Minolta MD 28mm 1:3.5 MD III
IMPORTANT NOTE: This was the first lenses-comparison on this site. That time I had a copy of MD 28mm 1:2.8 5×5 version and MD 35mm 1:3.5 in bad cosmetic appearance. So, after I got other copies of these lenses I remade the tests. No changes in conclusion and results but I recommend reading the latest article because it is more convenient. Here you can find it.
This comparison is correct only for conditions and equipment used for tests. An element changed – the result changed.
- Camera Sony A7II (24mpx, full frame) – RAW (ARW), tripod, A-mode, ISO 100, WB fixed, SteadyShot OFF, manual focus correction for every shot
- Targets (buildings) – fixed by gravity power on the distances in more than 200 meters
- ARW post-processing – Capture One, default settings, 100% crops 300×200 px
- Most of Minolta’s lenses haven’t half-clicks after the first aperture position. So, for example, aperture “F2.4” for MD III 28mm 1:2.0 means an aperture set in the middle position between F2.0 and F2.8. Same about “F3.5” for MD 28mm 1:2.8
- Sunlight changed during the session
- My Minolta N-MD 28mm f/2.8(5×5) looks like a survivor after a small nuclear war. I admit that it probably may has a very small contrast drop, but it seems that it doesn’t affect results

Minolta MD 28mm lenses comparison – final conclusion
It’s difficult to select the winner. You can see:
- Center – all are the same
- Middle – MD 28/3.5 is better than others (surprise!), MD 28/2.8 7×7 is in the second place, MD 28/2.0 is third, and MD 28/2.8 5×5 is losing here, but…
- Corner – MD 28/3.5 and 28/2.0 both are the same and noticeable better than both MD 28/2.8 which are the same too.
Additionally, it needs to remember that MD 28/2.0 has a faster F2.0, and MD28/3.5 has max at F3.5. So, I don’t know how to select the best one from this pack, because all of these lenses are good for different tasks. Firstly, it looks like a good idea to save money and take the cheapest MD 28/3.5 for landscapes only. On the other hand, faster 28/2 is much more universal. Additionally, both 28/2.8 are a very good choice for a person who occasionally uses this focal distance and needs for something balancing in “price/speed”-terms. So, please, make your personal conclusions based on these test results.
