Pentax 50mm lenses...how many versions are out there?

Hey I see a lot of people talking about the various 50mm fixed lenses. Which ones are manual focus, auto focus. Which will work with *ist DL?

Thanks!

Including 50mm Macro lenses I count 27 specific lenses issued by Pentax - this probably does NOT include minor cosmetic alterations that do not warrant a version 1 / version 2 designation, but does include the limited edition gold and titanium commemorative lenses issued around the milestone LX anniversaries.

For K-mount, here is a resource that answers all your questions Pentax "Normal" Prime Lenses

Here is a resource for most of the screwmount lenses Die Cast Pro - Pentax Lenses

Basically, with the correct adapter and settings, they will all work in at least a limited fashion on a Pentax DSLR, including the *istDL

Only talking about the faster ones... These are the ones i can recall...

M42:
Super Takumar 50/1.4 (v1)
Super Takumar 50/1.4 (v2)
Super-Multi-Coated Takumar 50/1.4
SMC Takumar 50/1.4


PK:
K50/1.2
K50/1.4
K55/1.8
K55/2
M50/1.4
M50/1.7
M50/2
A50/1.2
A50/1.4
A50/1.7
A50/2
F50/1.4
F50/1.7
FA50/1.4
FA50/1.7

Only the F and FA are auto focus.

They are all very high quality.

From my experience, the best i used where the S-M-C Tak and the SMC Tak,i traded them for the FA50 (the convenience of AF)

My advice: Close your eyes and pick one

Thanks for the quick reply...

Can you tell me what the K and A stand for? I assume the M is for manual?

Thanks

K and M are fully manual, you have to meter manually.

A has auto metering.

There are probably better explanations then this on other threads, do a little search if you want.

both K, M, and A are manual focus, the A one allows the camera to know what aperture you're working on, while the K and M don't allow that...
