Originally posted by SirJangly I picked it up. Now I think I will get a 135mm to play with, and go from there. Any similarly priced 135mm I should go for?
I have a
Pentax M 135mm f3.5 we can talk about but send me a PM for that. I won't be discussing the sale of That lens any further here other than to say that as 135s go, it is a nice compact lens that I think, is underrated.
However, Johnbee is correct. You should probably define some parameters as to need. Otherwise, you're going to end up with a cabinet full of lenses you never use. I understand if you're brand new at this and probably like a kid in a candy shop (I know I was). As to finding lenses, don't over rule looking for complete film camera outfits. Don't over rule getting an M42 adapter from Pentax and playing with the Takumar screw mount lenses (that fit the spotmatics).
Since you are playing with the M type lenses, spend some time learning what your camera meter is telling you and how to interpret it for your scene. It doesn't matter what type of camera or lens you are using, this is something I would recommend anyway. Spend some time studying how the different aperture settings AND distance to subject affect your Bokeh (since you mentioned it). Set your camera to M and turn off AF to get the feel for using manual lenses. The only difference will be how you set the aperture. When you get your 50mm, find the function in the custom menu that says "Using Aperture Ring" and set it to Yes and while you're at it, turn on "Catch In Focus". On the K7, these are options 37 and 35 respectively.
Then spend some time learning how to post process, even in camera, to get your desired effects. Even if you choose not to use them right away, I would be shooting RAW+ just so you have what is basically the photo negative for your pictures.
