Originally posted by keithlester No, the opposite is true. The adaptor has a little widget in it that makes it stay on the camera body and then you can screw lenses on and off without the mount coming loose. To get the adaptor off the body, you need first to remove the lens, flick a little sprung lever with your finger-nail or a small tool, and this will release the adaptor. Not so useful as you might have thought.
Yes and no. You are describing the ordinary way to do it. That's how it is supposed to work and probably the way most people do it.
I mentioned an alternative way to handle screwmounts: By removing the latch from the genuine Pentax Asahi adapter and securely attaching the adapter to the lens you can handle it the same way as if it was a K-mount lens. Care should be taken not to mess it up (and get the lens permanently attached to the camera...) but it is fully possible. I have one M42 lens only now, the Jupiter-9, and that's the way I use it. Conveniant in my opinion.
Originally posted by keithlester Plus, after having auto aperture, stopping down manually for anything other than landscape work on a tripod is a total pain in the round soft place.
That surely depends on your shooting style. I hope the original poster have considered this. From his posts I get the impression he knows about manual lenses.
For the fastest and most conveniant handling the FA50/1.4 is the way to go as allready mentioned. An even better option in this regard might be to wait and see what the upcoming DA55/xx will be like. I hope it will be a both fast and good lens with all the modern features like in lens focusing motor and full time manual override.
Originally posted by keithlester The SMC Pentax K-mount lenses are mostly every bit as good as the original Takumar SMC lenses. I have used both.
I agree. For the 50mm lenses, however, there are some differences and for anyone not minding the stopped down metering/handling the Takumar lenses can be a great option thanks to their rendering. I think Sean [carpents] has a nice gallery at pbase showing examples of this.
