My first was also a Minolta SRT-101 that I purchased new in Japan in 1968 and it still works fine. I had the lightmeter adjusted so I could use todays available batteries. Also had the camera cleaned.
In the 80's I was the photographer for a local chapter of IPMS and shot lots of pics using that Minolta. Didn't have a light meter so I would turn on my two "heat" lamps and take a reading using the in camera meter right next to the plastic model. Then back to the tripod, do the settings, and shoot. The photogs came out quit good. One series of shots I did was of a 1/12th scale Suzuki Katana by Tamiya that I had built. I shot slides and sent them to Fine Scale Modeler and they were published. Great film camera.
I started buying Nikon after purchasing a Coolpix 990, my first digital, and seeing the quality of that camera; it sold me on Nikon. I also have been infected since then with NAS!
