Mechanical Manual Cameras
The Nikon F2.
The little collection above is my 1977 Nikon F2 in a Nikon case. The case has room for 3 lenses in a chrome F mount keeper and a flash (where I keep my spotmeter).
The F2 was the sucessor the the F, and is a tough manual camera that needs no battery with the plain DP1 finder but when used with metered finders needs power to operate the meter only.
As you can see the F2 is a rugged workhorse, I'd hate to think how many films have been though it, but I have no doubts about it's reliability.
I have some pretty good lenses with my Nikons, the 28mm F3.5 Nikkor-HC 50mm F2 (superb) 85mm F2 (good and sharp) and the 105mm F2.5 (excellent)
These cameras are available for peanuts now, but at the time I started photography were the de-facto tool for most Pro's. So if you want to try a no batteries manual film camera, an F2 would be a great bargain!
