Cambo ACTAR-90 Reviews

Small, lightweight and sharp

I bought this to replace a Mamiya-Sekor Z 90mm lens I was using on my Cambo Actus and it is a noticeable upgrade. Not only is it so much more compact and lightweight, but it is optically fantastic. It's sharp corner to corner and has a large enough image circle to easily handle extreme shifts on a medium format sensor. Absolutely worth it.

a cute and great lens

It shows great image quality, all sharp except at f4, f22, in between is excellent. A picture below taken with D850, the 90mm lens tilted with a proper DOF to show every detail, directional or circular, very impressed.

It says it's incompatible with the Cambo DB Actus system, but does it look compatible?
Asked by: Roger
The Actar-90 is compatible with the Cambo Actus-DB2. Due to the lack of a leaf shutter in the Actar-90 and all of the Actar lenses, the digital backs that can be used with the Actar lenses are limited to digital backs that have an Electronic Shutter.
