Yes, but you will need a Pentax screwmount adapter or a similar third party adapter. Please see this page for instructions on how to install the adapter:
Pentax Screwmount Lens Adapter
Once you have installed the adapter, follow these easy steps:
1. Mount the lens. Make sure you tighten it so that all markings on the barrel are centered.
2. Compose your photo and adjust the focus.
3. If you're using a Super Takumar, S-M-C Takumar, SMC Takumar, or Super Multi Coated Takumar, you will need to set the diaphragm clutch on the lens to
manual.
Then,
select the desired aperture.
Note that your lens must be stopping down manually in order to get metering to work.
4. Meter the light. If you're using the K100D/K110D or the *ist DS/DS2/DL/DL2
, press the AE-L button. If you're using the *ist D or K10D, press the
green button. Make sure that the "allow aperture ring setting other than A" is set to yes.
When using a manual film SLR, meter as you would with any lens. Metering varies for later film SLRs.
5. Take the photo.
