None of the Nikon rangefinders have built-in metering. Not sure what you mean by usability compared to a Yashica CC. The Nikons are fully manual cameras with a longish RF baselength and interchangeable lenses. All have removable backs for loading film (no hinged door). All have the shutter button toward the rear of the camera body, directly above the film take-up spool (Nikkormats, Nikon FM2 and most later Nikons SLRs have shutter button toward the front of the camera). Minimum focus distance for wide-angle and normal lenses is 0.9 meters, 3 feet. All use a focus wheel with infinity lock for 50mm lenses that drives novice users crazy but is easy to get the hang of and allows for one-handed shooting. The most useable of the Nikons are the S3 and SP, which operate very much like Nikon Fs but are about 10 percent smaller, about the same size and weight as a Nikon FM2.

There are four main models:
Nikon S, built circa 1950 to 1954. Weighs 23 ounces (Yashica weighs 18 ounces, according to Gandy's Cameraquest site). Knob rewind. Two shutter-speed dials (fast and slow). Maximum shutter speed 1/500. Reduced-image viewfinder for 50mm lens with no framelines. No self-timer. Weird flash sync. Most common and affordable Nikon RF.
The S2, SP and S3 all have identical body sizes (5 1/4" wide; 2 7/8" high; 1 3/8" deep) (135mm x 75mm x 35mm) and weigh approximately 18-20 ounces (500 to 575 grams).
Nikon S2, built 1954 to 1958. Weighs 18 ounces. Fullsize 1:1 viewfinder (no image reduction) with etched frameline only for 50mm lens. Not parallax corrected. Maximum shutter speed 1/1000. Two shutter-speed dials. Modern folding film-rewind lever. No self-timer. Modern PC-socket flash sync with 1/50 x-flash speed. Rather loud shutter, makes a satsifying but audible "
clack-thump."Widely available and affordable. Most cost-effective when bought along with a 50mm f/1.4 lens, which is the classic and still-excellent glass for this camera.
Nikon SP, built 1957 to early 1960s. ("P" stands for Professional). Weighs 20 ounces. Quiet shutter (not as quiet as Leica M, but advertized as a "whisper" shutter). 1:1 lifesize finder with parallax-corrected frames for 50/85/105/135mm lenses. User-selectable switch for framelines. Separate wide-angle finder for 35mm/28mm lenses, directly beside the full-size finder, shows greatly reduced image (about 1/4 life-size) with no parallax correction. The arrangement allows easy shooting of wide-angle lenses for eyeglass-wearers, but separate finders for wide-angles would allow larger image for composing. Shutter speeds up to 1/1000 in single non-rotating dial. Flash sync 1/60. Self timer. A photographic/photojournalistic tool every bit as capable as -- many would argue more capable than -- an unmetered Leica M3, M2 or M4.
Nikon S3. Built 1958 to early 1960s. Identical to the SP but with a simpler viewfinder. Very large lifesize viewfinder with three etched non-parallax-corrected framelines for 35mm(at 1:1 lifesize! Not reduced like in a Leica M), 50mm and 105mm lenses. Small etched markings give a sense of parallax correction. Otherwise identical to an SP and a little more affordable. Some dislike the "busy" viewfinder with three overlapping frames. I like it because it allows life-size framing and focusing of the 35mm lens.
The "heart" of the Nikon system is its exellent lenses. These are not inexpensive but tend to be less expensive than Nikkors in Leica mount and less expensive than their Leitz equivalents. All Nikon RF cameras were hefty, rugged professional cameras in their day, and most have aged very well.
Prices estimates for good user cameras.
Nikon S, usually under $500.
S2 -- roughly $500
S3 -- usually under $1,000
SP -- usually above $1,000
Prices will be higher in Europe.
