After the Ricoh GR III came out, I’ve been looking for something with a similar form factor but in analogue format. The original Rich GR1 that uses 35mm film is now way too expensive ($600 and up as of June 2019). All film cameras seem to be jumping up in price, but the one jumping up the least and offering decent lens quality is the Olympus XA.
As you can see from the sample files, it works quite okay for photos where you don’t need 1/1000 of a second or faster. When you need that quick street shot, you often end up with motion blur.
Kodak Tri-X 400 especially when pushed one stop offers a nice bit of contrast with rich blacks, and grain that doesn’t detract or is too noticeable. I’ve used other film stocks like Ilford HP5+, another great film. Since the Olympus XA already has soft lens look wide open, that in combination with a flat film like HP5 makes it a tough combo to use. If you’re going for a dreamy and grey effect though it could be worth a shot. For me, Tri-X is the film to use with the XA.
