Today I tested a 28mm lens made by Super Orion. I can not find much about this brand, its probably a copy of some other branded 28mm lens. I bought it for around 15,- USD with the hope I could bring it with me together with my 50 mm lenses. On my Fuji crop sensor it is around 42mm, almost wide angle for me. But the lens is not so good, specially not for landscapes. It is soft overall and sharpness is important in landscape photography. I took a lot of pictures today on different apertures but they are all soft and at 2.8 it is really bad, you can see some examples down below.
I also took some pictures in the museum where I work and for these kind of pictures I don’t mind that the lens is not sharp at f2.8, the aperture I used to shoot the pictures inside. In lightroom you can still make something nice out of the RAW files. There is not so much vignetting to see and the distortion is hardly noticeable. The lens also misses some “vintage picture” quality. The pictures look quit neutral with no muted colors or other charms that some of my other vintage lenses have.
The lens id nicely build, for the most part out of metal I think, it has an ensuring weight to it. I don’t think it is a lens I would bring with me, specially if I have a choice.
