Sekor 2,8Mamiya-Sekor E 28mm f/2,8

(7 groups / 8 lenses)

Mamiya-Sekor Mount Ten gold plated contacts but not extremely slick functions. Changing the lens needs more force than for instance in Olympus or Minolta cameras.

Sekor f1,7/50mmMamiya-Sekor EF 50mm f/1,7

The optical design of E and EF lenses are similar. EF lenses have an ability to read the focused distance from the lens.

That function is switch able and works with Mamiyalite Flash Units/ZE-X and controls the flash for a proper exposure.

Mamiya-Sekor Lenses are famous for they excellent quality , equal to most top-rated brands, like Nikon, Canon, Leica etc. On ebay or in a second hand store you may found a real jewel at a considerably low price. I mean that they are really excellent for taking pictures, not only for a nice decoration on the collectors vithrine. (like mostly in my case) Sekor 28-50mm

Sekor 200mm

Mamiya-Sekor E 200mm f/4

A nice medium telephoto lens (5groups / 5 lenses)

Mamiya Sekor Zoom E 80 ~ 200 mm f/4

I suppose that this lens is quite rare. It is a Mamiya-Sekor lens but it is not indexed "anywhere"

1. The zoom mechanism differs from the "original".
2. Largest aperture is f4.0 not f3.8
3. Serial number is very low / 11031

Sekor E 80-200
Mamiya Sekor Zoom 70 - 150mm f/3,8 E
(9 groups / 12 lenses)
The Mamiya-Sekor E and Mamiya-Sekor EF series lenses contain special electronic contacts which exchange information with the camera's built-in microprocessor, enabling functions such as total electronic aperture control and compensation. Some important focus-lengths and special lenses can´t be found in Mamiya-Sekor Z-Series lenses.
This deficiency may have substantially caused bigger problem only in the professional use.
