The MZ-3 is a cheap plastic camera from 1997 that strangely has become my one of my favourite Pentax film SLRs. It is electronic so it will only work with two CR2 batteries for shutter/meter/film advance. I don’t have any autofocus lenses so I only use it with manual lenses, and although the viewfinder screen is not as crisp as the ground glass of Pentax manual cameras such as the MX, I have not had any trouble focusing the MZ-3. There is a focus detect function, but I have not had an instance where I had to use it. The size and ergonomics are perfect for me, the grip on the front and the small contour thumb rest on the back make it very comfortable to hold. The plastic construction makes it light, but not unbalanced with smaller lenses and short teles, although I can see longer teles as being a problem. The major benefit is both the high shutter speed (up to 1/4000) and the inclusion of a spot meter. My preferred method of shooting B&W film is to spot meter the shadows and manually adjust the speed up by 2 stops, or simply meter something in Zone 5 and press the exposure lock button. Typically I would just let the camera pick the shutter speed. The high shutter speed allows you to use the glorious fast lenses like the SMC 50mm 1.4 or the 50mm 1.2 in daylight, even with ISO 400 speed film. The built in pop-up flash is great for snapshots when you need it without the bother of mounting an external flash. I believe all the MZ-3s came with the annoying date back door, but I easily replaced it with the back door from my MZ-5 to get rid of the needless additional bulk. The advantage of the all-electronic 1990s camera is that the shutter speeds will always be accurate, the meter is excellent, and if it breaks, you can replace it with another for only $20-$40! The MZ-3 may not feel as nice as a Pentax LX or a K1000, but it will get the job done. Purchase Pentax Mz-3 here.
