I have a nice black MX together with the 50mm f/1.7 lens, great combo but I think it would be fun with more options.
I know that I can mount the Pentax-M lenses and Pentax-K lenses on my camera but what other lenses can I get for it?

Can I, without any problem, mount Pentax-A lenses on my camera aswell?

Sorry if this is a common uestion..

you can actually even mount AF lenses.

the only ones you will have issue with are FA-J lenses and DA lenses as these lack aperture rings, and can only be effectively used on program plus and later A bodies. I say effectively because the FA-J lenses actually have a link for the aperture coupling so that the camera can meter, but you only shoot at minimum aperture (like F22) so use is pretty limited

Thank you Lowell! Good information.

Not knowing how familiar you are with Pentax I thought I'd give you something else to consider. One of the greatest things about Pentax is lens compatibility, meaning you can use your 50/1.7 on the newest DSLR offered without any adapters. You can also use any newer lens, as long as it has an aperture ring, on your MX.

If you'd like to use other newer Pentax cameras, such as auto focus bodies (film or DSLR), you may want to look at the F- and FA-series lenses. They'll work great on your MX too and be completely compatible with manual and auto focus cameras. The price will increase a bit with auto focus, but there are lenses in the 28, 50 and 135 range in those series.

Hi,
I am intending to go for K5 or K5IIs. I am not really familiar with moire problem and how to solve - means shoot without moiree. I do not have enough experience to exactly know what is the limitation of the camera.
EG. shooting in the city -scapes, sea, shooting people whom has a dress with patterns etc. I also do not know where is the limit of 16MP in terms of resolution.
I suppose Lightroom will do in case of moiree.

I'm fond of neither 50mm nor 28mm focal lengths for my 35mm film SLRs.

My Pentax film SLR has a 35mm (M35/2.0) "normal" lens mounted most of the time.
I also carry a short telephoto "portrait" lens (M100/2.8) which I use occasionally.

To me WA is 24mm and below. I have a 24mm lens which I seldom carry.
The same applies to my telephoto lenses (M135/3.5 and M200/4.0).

Sorry, I can't help you here. I don't know anything about the K-5 cameras or moire.

I can understand the above comments as I believe 35-40mm film equiv is a great walk around fov. I therefore like a 28mm prime on APS-C as it equates to 42mm on FF. A 24mm would also do this job but are less common than 28's.

Yes, 35mm makes a great walk-around lens. I shoot my FA 35/2 on my K-mount cameras and the Jupiter-12 35/2.8 on my FSU rangefinder cams.
