Aye, as others have said, set it for 50.

Jamie, you are 100% correct. Even for an inexpensive lens it is no slouch.

M 50/2

Check the above link to see if yours is one of the later types. If so it may have a little collector value as a bonus.

Well, you learn something new everyday so thanks for this information. The M50/2 that came with my K1000 in January 1987 appears to be one of the late lenses with a serial number of 8717961. It's been known to produce a decent photo now and then.

Two points related to the original post:

1) When I shoot a lens on my A1.4x-S tele-converter I do factor the lens focal length for SR by 1.4x. Yep, common sense. For my 135mm on the converter, I set the SR to 200mm and I get good results. A unique combo telephoto is my 50/1.4 Super Tak on the TC with SR set to 75mm.

2) If you use the reciprocal of your lens focal length for your minimum shutter speed for hand-held shooting I believe you should "crop-factor" that speed. For that 50mm I'd use 1/75th minimum for hand-held. The old reciprocal rule of thumb was borderline effective before SR.

For me, it's useful in communicating people who have experience with 35mm film but not with APS-C / digital. I have only very limited experiencing actually *using* a 50mm lens on film, but I understand the crop factor business, I have a pretty good what it would look like - it's a little narrower than my 28mm and a little wider than my 40mm. So when film people talk about using a 50mm lens on their film cameras, I have some idea what they are talking about.
The equivalency is much more useful for P&S and superzoom cameras where the sensor is much smaller. On my Fuji S5200, the sensor has an approximate 6x crop factor, so using 36-360mm Eq is useful, compared to the actual 3.6-36mm focal length of the lens.
