Mamiya Sekor 80mm f2.8 - vintage medium format lens for Mamiya 645 cameras with a film size of 6 x 4,5 cm. That is, it covers a much larger area of the frame than modern Fujifilm Medium Format Cameras.
I tested this lens on a full frame, on a crop, and also on an interesting medium format adapter Vizelex Rhinocam (which I will talk about separately).
It is a well-built metal lens with manual aperture and focus rings. To mount on cameras with Canon EF mount, you need such an adapter.
What are your impressions of the Mamiya-Sekor C 1: 2.8 f = 80mm?
Full frame - this is a nice soft-painting portrait. It has very decent detail. There are no problems with sharpness. But on the other hand, this is not a “ringing” lens. Now everyone is chasing the maximum micro-contrast and razor sharpness, this is not about Mamia. And I don’t think this is bad.
Sample photos on Mamiya Sekor C 80mm f / 2.8 + Canon R5
The bokeh is pleasant despite the complex background.
Lenses such as Canon EF 24-70 f2.8L IIThe Sigma 40mm f1.4 ART, gives you the ultimate in detail and maximum contrast. But for portraits, I consider these qualities superfluous.
For portrait photography, I really liked the Mamiya-Sekor C 80mm f 2.8 N. The soft pattern and pleasant bokeh create a very pleasant photography experience.
An integral minus - manual focus... It is inconvenient, it takes time and you can miss some points, which of course limits the scope of such optics.
This lens has a color shift that needs to be taken into account when processing RAW files.
