Used Mamiya-Sekor Z 90mm f/3.5 W Lens | Black | U7

The Mamiya-Sekor Z 90mm f/3.5 W is a high-performance standard prime lens designed as a core workhorse for the Mamiya RZ67 medium-format camera system. Providing a "wide-normal" field of view equivalent to roughly 44mm on a 35mm full-frame sensor, it delivers an incredibly natural and unforced perspective that mimics the human eye. The lens features a 6-element, 6-group optical design and a mechanical Seiko #1 leaf shutter capable of flash synchronization at all speeds up to 1/400th of a second. Its f/3.5 maximum aperture allows for solid background separation and light-gathering capability, while the robust metal body utilizes a highly practical 77mm front filter thread. Additionally, the "W" designation signifies improved modern optical coatings and structural refinements, making it highly favored for everything from expansive landscapes to close-up studio portraits.
