Is the Bower 85 lens full frame compatible? Might be nice w/ film if it is.

anyone no anything about horusbennu 50mm f1.7? brand new on ebay £42 seems like a steal to me,

Oh, man, i got a Pentax M 50mm f1.7, and I really like it, but I almost regret not getting the Horusbennu instead. It seems like a very interesting lens. There is a thread on these forums about that lens and it shows that the lens actually is sharp and can have a quite artistic rendering. Put a nice hood on it and it should be fun.

It IS possible to use your M-series lens as though it is an A-series lens.
All the information you need is contained in a combination of these two threads:

Summing it up:

1. Short the A contact on your camera body
2. Insulate so your body knows the minimum & maximum apertures
3. Run a series of test shots and develop a cheat sheet for exposure overrides.

It works well, It isn't hard, it doesn't take a whole lot of time, it makes no permanent change to your equipment, but a lot of photographers perfer having full manual control over exposure and flash anyhow so it isn't worth their time to do the work. Me? I like having the option to go either way, full-manual or some level of automation.

You can also use it in Av (Aperture Priority) mode, with the lens always at maximum aperture. Occasionally useful. Congrats on the lens.

Have you enabled the "using aperture ring" setting?
