Mamiya was well aware that introducing a new professional SLR (the Auto XTL shown above) and a new proprietary bayonet mount would require a set of dedicated lenses. Therefore a (for its time) rather complete set of lenses was offered:

* Sekor ES 4/21mm
* Sekor ES 2.8/28mm
* Sekor ES 2.8/35mm
* Sekor ES 1.8/55mm
* Sekor ES 1.4/55mm
* Sekor ES 2.8/60mm Macro
* Sekor ES 2.8/105mm
* Sekor ES 2.8/135mm
* Sekor ES 3.5/200mm
* Sekor ES 6.3/400mm
* Sekor ES 8/600mm
* Sekor ES 8/800mm

* Sekor ES 4.5/90-230mm
