Super Takumar 35mm f/3.5 on Sony A7
This is a classic lens approaching 45 years old, does it still deliver?
This old classic wide angle is extremely well built. It is nicely weighted and has smooth focus. The lens has hardly any coating compared to a new lens, only single coated. This means more flare, but I think they also provide a nice natural look to the images.
The lens is fairly compact and dense, weighing in at 150 g. It has 5 slightly curved aperture blades, and a long for the class minimum focus distance of 0.45m. It has a fairly basic 5 element construction and small max aperture of f/3.5.
Note: 4k video is 2160 LW/PH

Comments on the Results
Resolution follows fairly classic lens performance, improves steadily up to f/8 or so, with center leading corners. By f/8 the MTF20 is high across the frame, but wide open corners are fairly weak. The MTF50 is lower across most of the frame relative to the M20 vs what the Canon FDn 35mm f/2.8 was, maybe a sign of less efficient coatings.
Distortion is slightly worse than average at about 1.6% barrel.
Lateral CA is noticeable in the corners wide open, but is not severe.
Flare resistance: Haven’t checked, but probably not great.
Measured Focal length is 36mm at 1:35 magnification
Pros and Cons
- Solid performance at f/8
- Build Quality
- Inefficient coatings
- Corners at large apertures
The colors are selected based on overall MP, don’t compare the colors between systems. So relative to max sensor resolution this doesn’t do as well as the lens does on the A7 relative to its (lower) sensor resolution, but it still resolves more detail on the A7R then it does on the A7.s
This lens does surprisingly well given the age. It has a great feel to it and is very usable for portraits even wide open, or for landscapes if you stop down. It isn’t to the level of some modern lenses wide open, but not at all bad. In the extreme corners at f/8 it resolves better than the modern ZEISS 35mm f/2.8, but the ZEISS does much better at larger apertures.
Consider donating, it is about $50 a lens to rent.
