looking for some data,  approximate age, etc.. Russian made F8/500mm mirror, Nikon mount,   PN MC 3M-5CA.

It has a small symbol on the side like the Chrysler emblem, 4 'arms' inside and 'CCCP' over the 'arms'.  picked it up at a yard sale, rumored to have been used on a Nikkormat.  won't fit my D70 but with an extension tube could be used as a macro lens.

MTO (MC) 3M-5CA 500mm F/8, a lens created by russian company LZOS following the Maksutov design from russian optical engineer Dr. Maksutov ( hence the MTO 3M-5CA getting its nickname 'Maksutov' ).

Type: (MC) 3M-5CA
Focal length: 500mm
Aperture: F/8
Weight: 620 gram
Focus mechanism: Manual
Aperture mechanism: Fixed

Product page for the lens on the LZOS site can be found here.

MSRP: $270

While it is still being sold, one site said production on the lens stopped in 2008.  Probably the only way to find out the exact age of the lens you have is by the serial number.  If paperwork was included with the lens, manufacture date or batch information might be included.

Hope that helps.

ATB,
Sam

hi zeke - why won't it fit your D70? or do you mean it won't auto focus and or the camera won't meter. There are very few f mounts that won't fit your d70

interesting stuff - is either a nikon mount or is not a nikon mount. only a few (like an old nikkor fisheye) won't mate to your d70. the  mount will work but the protrusions from the lens internals at the back will damage the camera

if the mount dosent line up is not a nikon f mount and is why it only cost 5 bucks i would guess

adapters are plentiful for around 20 bucks and sure focal length will change but the only real loss is that true infinity focus will lack

but you need to know what to adapt from

interesting stuff indeed

I've owned one of these lenses before.  As others have mentioned it is a matsukov lens design which also was rebranded as "zenitar" in addition to "lzo". russians were trying to copy zeiss lenses at the time since those were held in higher esteem (and still do due to their optical coating).

The lens that I had owned was a 500 f/5.6 which is similar to your lens but larger.

these lenses typically are characterized with having bokeh donuts. For me personally, I used this type of focal length to shoot architecture and non moving objects as focusing with this lens by hand is no easy task. You will need to use live view for this lens as it is very tough to focus with the stock focusing screen. I still kind of regret selling mine.

helpful tips
1. Use a tripod
2. Use a minimum shutter speed of 1/400
3. Shoot with the sun at your back to keep contrast nice and rich.

russian mirror lenses are better than tamron or sigma lens equivalents as long as the mirrors are still aligned.

best of luck!

Another way of using this lens would be to get a micro 4/3rds camera body (Olympus & Panasonic do these) and a Nikon to micro 4/3rds adapter - you'd end up with a lens that can focus to infinity and an equivalent 35mm focal length of 1000mm.

Micro 4/3rds cameras are a great way of using old lenses as there are many mount adapters available, and as micro 4/3rds cameras have no mirror, there is room for the adapter without causing problems with infinity focus.
