Old lens

I have an old Praktica LB 35 mm camera with a AUS JENA T 50mm f:2.8 lens, this lens in screw mount, is there any possibility to fit this lens on my K 100d pentax camera, i think it is a very good lens and it take superb photos with my praktica

Thank's and excuse my english, i live in Quebec and i speak french but a little english too.

Bonjour Norm!

You can get an adapter to use with your M42 lens and it will work (full manual) on your Pentax.

Welcome to the forum, too.

Is there an auto/manual switch on the lens?

Hi Norm,

If there is no auto/manual switch on the lens (I have a Zeiss Jena without one) then you can normally only use this lens at full open aperture. You need to hold the depth of field preview button (on the lens) at the same time as taking the shot to use it at any other aperture.

If it does have an auto/manual switch you need to set it to manual.
