manual lenses on pz1p how does it all work
Can someone pls help me on the following questions? 1. With a manual focus lense on a pz1-p you don't have auto focus after all its a manual focus lense. If the camera is set on auto will it set the shutter speeds and aperture for you or better still will the function of me manually selecting the aparture will the pz1 automatically set the shutter speed (visa versa? 2. With a screw mount manual focus lense on a pz1-p you don't have auto focus after all its a manual focus lense. If the camera is set on auto will it set the shutter speeds and aperture for you or better still will the function of me manually selecting the aparture will the pz1 automatically set the shutter speed vica versa?

If the lens is an A, F or FA lens, then the camera can select the aperture, as long as then the aperture is set to 'A'. If it's an M or K lens, then you'll need to set the aperture yourself on the lens. This assumes that the camera is in P, HyP or HyM modes. Changing the shutter speed will only change the aperture if the lens is set to 'A'. 2. With a screw mount manual focus lense on a pz1-p you don't have auto focus after all its a manual focus lense.

M42 lenses (screwmounts) are similar to M or Kle lenses as above, but you also have to stop down to meter at your desired aperture. i.e., if you have an M42 50/f1.4, and you want to take a photo at f8, you need to set the little lever on the lens so that it's gets darker when you close the aperture, then set the aperture to f8 to meter. The camera won't close the aperture for you when taking the picture like it will with K-mount lenses. dave -- dave o'brien - http://www.diaspoir.net We give advice, but we cannot give the wisdom to profit by it. -- La Rochefoucauld - This message is from the Pentax-Discuss Mail List.

The answer is, it depends. You have to remember that there are two types of manual focus lenses. The A and the M versions. The A version has all the proper electrical contacts to allow the camera body to control the aperature, and has an A position on the aperature ring just beyond the min f-stop mark. The M version does not, and the aperature must be set via the lens itself. Therefore, with A series lenses you have all of the same metering (Matrix, CW, Spot) and exposure modes (HyP, HyM, Av, Tv) as with autofocus lenses. But with the M lens you lose the HyP, and Tv exposure modes, and the Matrix metering mode. In other words, with an M lens you lose any features that require the body to control the aperature.

Well, technically, assuming that you're talking about the K-mount MF lenses, there are also the SMC (K) lenses, but they also lack electrical contacts, and work just as the M lenses do, as described.
