- At a wide angle, soapy at the edges, but everything is relative, plus geometric distortions. At 35mm it's quite good, including sharpness. Light. Good pseudo-macro, allows you to shoot small objects. The front lens does not rotate (you can use a polarizer), it easily switches to manual focusing. One of the best whales in all mirror optics systems (according to most photo sites). (Review for the second version of the lens).
- Of course, it is inferior to more expensive lenses, especially fixes, but at the eighth aperture, the difference is practically not visible.
