After some silly initial concern about the AF on my recently aquired K-r, I have have really fallen head over heals for it. I am getting great pictures with it and have tons of fun shooting and reading everything I can about how to work my camera. One of the big draws for me to get a Pentax over the other guys is the ability to use vintage glass with it. I was in the market for a good portrait lens and after reading lots of reviews here I picked up a PENTAX-M 50mm f/1:1.7 SMC off ebay for about 40$, it's in the mail as we speak. I am very excited to crank the aperture all the way open and take lots of shallow dof pictures of my friends and family. I am also excited by the prospect of using a manual focus lens, sounds like fun.
I wanted to ask a few questions about the lens just to make sure I understand it correctly.
1. I can use this lens with any adapter? Just screws on?
2. I am under the impression this lens will only work in manual and aperture priority mode, am I correct?
3. Will my meter work correctly with this lens, or do I need to learn to eyeball it?
4. Will the AE-L, focus check botton work with this lens?
5. Will I want to invest in a Katzeye for my view finder, or should I be able to make do with the one I have?
6. Anything else I need to know about using older pentax lens?
I also wanted to ask for suggestions for other cheap lenses I could get that would help me replace my kit 18-55 lens. Thinking I could use something a little wider than the 50mm for landscape and such. I am excited to start collecting vintage glass for this thing!
Thanks
1. Just shove it on like any other lens, remembering to set the camera to M. When you switch the camera on, it will prompt you to specify the focal length of the lens, so that the shake reduction operates correctly. Without that the camera has no way of knowing.
2. In AV it will meter (not focus), but permanently wide open. Quite nice if that is the effect you want (i.e. very shallow DOF)
3. Put it in M, set the aperture with the ring on the lens, then press the button on the camera (can't remember which one it is on the KR), and that should roughly set the appropriate shutter speed.
4. Don't know
5. A Katzeye helps but you can survive without it if you make use of the focus confirmation light in the VF. Trap focus is also a very useful technique (see various threads on this).
6. Trial and error is your friend. I also have an M28/3.5 which works well and is not as tricky to focus; an M100 2.8 which is an excellent lens, and various others.
M lenses produce good results; they are also very nice to use, and teach you a lot in the process. And they don't cost much. Have fun.
