I didn't have any autofocus lenses for the Sony a7c (24MP, FF). I thought about buying one, but didn't plan to. But by chance I saw the Samyang AF 35/2.8 FE on sale for only $130 (new). It was the cheapest full-frame autofocus lens on the market for the Sony FE (even if looking used).
I can't say it's my dream lens. But it's small, lightweight and the focal length suits me, so I bought it.
(lens with the original "hood" attached)
It's really new (unused) but from old stock. I tested it out, it works.
By the way, f/2.8 on a full-frame sensor is equivalent to f/1.9 on a sensor with a 1.5x crop factor.
The design is 7 elements in 6 groups, 7 aperture blades.
The filter thread size is 49mm. And 40.5mm with the original "hood" (included).
Unfortunately, since the lens was made some time ago, it has the old v.04 firmware, while v.07 is now available:
It is impossible to update the firmware of the Samyang lens on the camera, you need a separate lens docking station. This is a drawback of the Samyang lenses.
First of all, I liked the electronic interface of the lens: EXIF information (model, focal length, aperture), data for IBIS, profile application.
