Kenko KF series
The cameras accept different lens mounts. The KF-1N and KF-2N accepts Nikon F Ai mount lenses. The KF-1N is available in black and silver, but the KF-2N is only available in silver but has a higher maximum shutter speed. A model called KF-3YC uses Contax/Yashica lenses and KF-4PK uses Pentax K mount lenses. A limited edition KF-M1 was also produced for Japanese camera retailer Map Camera. It is exactly the same as the black KF-1 but does not have the Kenko branding, in fact it does not have any branding.
Except for the KF-2N, they share similar specifications including shutter speeds from 1s to 1/2000 with B. Flash sync at 1/125 a sec. The self-timer has a delay of approx 10 sec. A TTL center-weighted metering system using a silicon photo diode has a range of 5 to 17 EV at (ISO 100, 50mm f/1.7), settable to film speeds from 25 to 3200 ISO. The finder has a 92% field of view with magnification 0.91x (infinity). The matte focusing screen has a split-image device and microprism. The film transport uses a advance lever and a rewind crank. Power comes from two 1.5v SR44/LR44 batteries.
