    Here she is... Praktica MTL 5B.. made from 85 to 89 I think.. that doesn't matter too much though, unlike digi cams age doesn't matter, as it's the film roll that depends on the picture quality.

    As you can see there are two lenses there. How can I tell what they are? I'm pretty sure the smaller one is just a 35mm, but how can I find out the other one? It doesn't say on it whether it's a 200mm or whatever, but it's pretty tight. I found an old manual for the older model here, so I'm gonna use it to figure out all the numbers and that on the lenses.

    I'd have put this into the film photography forum, but I figured that the question was about lenses, thus could fit in both digi and film, or here.

    And what does the "B" stand for. It gives me unlimited shutter open time, which is what I've dreamt for, but I don't know what the B stands for.

    Thanks.

    B for bulb is my guess.

    B stands for bulb.

    Look at the end of the lenses. From the photo I can just barely read the end of the smaller lens. Looks like it says 1.8/50, which means it's a 50mm f/1.8

    'Bulb' traces back to the old days of photography when a shutter was sometimes actuated by a squeeze-bulb connected by tubing to a cylinder/piston mechanism. Exposures in seconds were the rule for interior studio exposures. When you squeezed the bulb, the shutter opened. When you released the pressure, the shutter closed. The 'B' designation stuck.

    Thanks for the link and explenation of B, Torus.

    Does anyone know, can you buy any lenses for an SLR camera, or are there designated lenses for each type/model?

    I've tried looking for some MTL 5B lenses but I'm not having much luck.

    I believe your camera has the M42 screw mount. If your lenses simply screw into the camera, that's it. There are a zillion lenses available in a huge number of focal lengths in the M42 mount. Lenses with other types of fittings will not work without some sort of adapter, if at all.

    Lenses for Pentax Spotmatics are M42.

    That's awesome, thanks!

    I'll get googling, but does anyone have any sites on hand that sell the M42 range?

    Oh yes, almost forgot. My film roll is ISO 200, but I took one photo on ISO 12 to see how it comes out. Will it?
    I'm not sure whether my cam needs to be on ISO 200 setting or not for it to expose properly.
