Just How Good are Mamiya CS Lenses?
"I have tested many different lenses for all kinds of 35mm SLR cameras, including many renowned and excellent Zeiss lenses for the Contax SLR system. The Carl Zeiss Planar 50mm f/1.4 lens, for example, is one of the best lenses available for any 35mm camera. The lens tests I have done with Mamiya CS lenses reveal that the Mamiya 50mm standard lenses come very close to the performance of the Planar. There is still a small difference, but that will most likely not be noticeable in daily shooting situations."

Additional Mamiya Accessories Available for the NC1000
The following are the original Mamiya accessories that were available for this camera:

Filters: A series of five high-quality filters, designed to maintain the high performance of the Mamiya-Sekor CS lenses. They come in 49, 52 and 58mm sizes, and in the following types: SY48 (Y2), SO56 (O2), SL39 (UV), YG, SL-1B (skylight).
Lens Hoods: Screw-in lens hoods are available for the 28mm and 35/50mm lenses. Telephoto lenses have built-in retractable lens hoods.
Diopter Correction
Many near- and far-sighted persons have difficulty looking through a viewfinder wearing glasses, but cannot focus accurately with them. Diopter Correction lenses, available in six different strengths, adjust for this deficiency.
Rubber Eye Cup: The Rubber Eye Cup, mounted on the rear viewfinder, helps prevent unwanted light from the back and sides.
Magnifier: Useful aid for critical focusing required in close-up photography. Mounts to rear viewfinder. Image size is doubled, and the Magnifier provides for diopter adjustment.
Angle Finder: Useful for low angles, the Angle Finder has click stops every 90º and freely rotates 360º. Has built-in diopter adjustment.
Extension Tubes:
A set of three tubes of different lengths, which mount singly or in combination between the camera body and lens. Useful for close-up photography. Diaphragm automation of the lens is retained.
Auto Bellows: A versatile bellows unit for photomacrography. Rack and pinion control allows precise adjustment. Additional features include a double cable release for diaphragm automation and provision for mounting the lens reversed, for large magnifications.
Slide Copier: Used with the bellows unit, the slide copying attachment is mounted in front of the lens to allow copying of slides and filmstrips. It has a slide stage that makes it easy to crop mounted slides, and a removeable film tray to facilitate copying long rolls of 35mm film.
Bellows Stand: Actually a small stage for photographing small objects. The platform rotates to allow for best positioning, and has clips to hold objects in place. The surface has a reflectance of approximately 18%, ideal for exposure measurements. A clear glass stage is provided for backlighting and incident light measurement.
Focusing Screens Five interchangeable focusing screens are available. Rangefinder Spot 45º/Microprism is the standard screen with the camera. Rangefinder Spot is an all-matte screen with a Fresnel lens and central rangefinder spot. Microprism is entirely matte with a Fresnel lens and central microprism spot. Matte is all matte with a Fresnel lens. Excellent for close-up photography. Cross Hair is a clear transparent screen with a Fresnel lens and a cross-hair at the central spot.
P-Mount Adapter: This adapter permits the use of universal (42mm) screw mount lenses on the Mamiya NC1000. Diaphragm automation, where applicable, is fully retained.
