This is a late 70s' SLR camera from Fuji Film in M42 mount. The only difference between ST705 and ST705W is the W version is able to mount a motor winder. It is a fully manual camera without any automation. There are vast choices of lens available in M42 mount. However, the Fujinon M42 bodies are different and support open aperture metering. The lenses have a tab which operate a pin which tells the camera what aperture is set to. Hence open aperture metering is possible. The camera is very light compact. It weighs a lot less than my Chinon CS and CXII. The focus screen is quite a bit brighter, making it much easier to focus. From what I know, Fujica was the last camera company to abandon M42 mount as all other companies switched over to bayonet mounts which allow much more automations. This was what photographers were demanding at that time.
One of the reason I like these cameras is they are fully mechanical and the batteries only drives the meter. Without batteries it is still able to operate normally. I did have to renew all the light seals and mirror bumper. I also cleaned the mirror and focus screen. Although all the shutter speeds were working and appears to be accurate, I removed the bottom plate and lubricated all the small gears and cogs.
What sets this camera apart from other cameras of the time was the ability to meter without stopping down the lens. Also, the light meter uses photo sensitive diodes. Cameras of that era typically uses Cds which is slower and less sensitive to light. Also, it uses 2 x LR44 or SR44 batteries. They are still readily available. Lots of cameras of that time were still using mercury batteries which are illegal now.
I loaded the camera with Kodak Colorplus 200 and went on a photo walk photographing portraits on the streets of London. The lens I was using was Fujinon 50mm f1.8. I found the camera exposures to be accurate and consistent.
