Thank you petro chemist and others for helpful advice. I know you are all experts on pentax.
my lenses specifically are
SMC Takumar 1:2.8/105
SMC Takumar 1:3.5/35
SMC Takumar 1:1.8/55
SMC Takumar 1:4/200
Would love to put them back in use and would buy second hand modern pentax dslr if I thought it would work.
Would be grateful for any further advice/comments. Thanks

I own 3 beautiful Takumar SMC Screw lenses which I used in my old Spotmatic film days. I now use Nikon Kit but would love to get these superb glass lenses back in use. Can't be adapted for Nikon but wonder if a mid price Pentax DSLR can be used with adapter.
