Ricoh KR-5 Super II is a mechanical camera and I had one too. It's light and fits the hand very nicely. It is made by Cosina, there are many other brand using the same body OM2000, FM10, Yashica FX-2000 Super. They are the same body with different mount, OM2000 has spotmetering I *think*. It uses 3 LED +/ok/-, the cocking is very nice and smooth and shutter is kinda loud.
It's a nice little camera, mine doesnt seems to have a very acurate meter compare to my EOS50e, KX or MX which I meter with grey card produce the same reading. The KR-5 Super II is sometime correct sometime off and can off for like 2-4stops. Maybe mine got some problem but since I have KX/MX for K-mount I din send for checking but also it's good enuf so I keep it.
Ricoh len I heard is not bad too. The later model are build by cosina, there are some zoom with made in korea label are made by Samyang. The len I have with the body RKN 35-70mm f3.5-4.8 is a wonderful len, it's one of my very best K-mount leh although cheap looking. Very good, sharper then some SMCs, Sigma I've got.
Weakness: Although the len mount is metal, the aperture coupling ring is plastic. This shd not be a problem but "chor-lor" ppl like me may mishandle and broke it
There are ppl who remove the timer as many said the gear wheel inside the timer is plastic and intime to come it will be deteeth and fail. However, the timer is also the mirror-lock prefire meaning it actually flip up the mirror before shutter fire during timer mode to reduce vibration. LED on it is bright large, it's nicer then the MX one which is alittle too small and confusing. Very hard to see in bright light too. The KR LED dont have this issues.
There are cheap, I bot mine from ebay in mint condition ard US$40+ with flash, body and zoom.
