|I decided to compare the Topcor 35mm f/2.8 against my modern Fuji 35 mm f/2 and Mitakon 35mm f/0.95. I have more pictures and better controlled tests. However, the results fall into a known pattern.
The colors and contrast on all lenses are fantastic.
Handling on the Topcor and Mitakon is excellent especially the focus ring.
All are very sharp lenses and snap into focus.
Topcor is sharp, but in last place here. Fuji is next. Mitakon here is playing on a different level when it comes to sharpness.
Here is where the Topcor falls apart and is showing its age. When you look at the leg of the candle stand you see that even when mounted to a APS-C sensor and using mostly the center the corners start to go soft. The Fuji is sharper in that area. The Mitakon is the sharpest with the best corner performance.
This trend basically continues to any sample shot I tried. When it comes to landscapes the Topcor corners are soft wide open and don't become sharp until f/5.6 or f/8. The Fuji and Mitakon do much better here. The Topcor is not a landscape lens. It's a great lens, but I would keep it for artistic pictures and rendering.
The most interesting result was taking pictures of a pineapple palm tree trunk the Fuji 35mm f/2 showed more chromatic aberrations than the Topcor 35mm f/2.8. Both stopped down to f/4 and both out of camera jpegs. Since this is a native Fuji lens Fuji has the advantage of in camera correction but did worse.
Interesting comparison. I have a question, not a challenging one but a plain one
The Fuji and the Mitakon are designed for APS-C, while Topcor is designed for full frame 35mm. The image circle would be different in terms of lens design. So would this be an apple-to-apple comparison, even if all of them are put on an APS-C camera (I am assuming so)?
