You mean that you haven't tried yet?

In the beautiful world of Pentax, cameras are backwards compatible with any lens manufactured by Pentax. So just snap it on and start shooting.

For manual lenses:
- Set the K200D program switch to manual
- Select your aperture on the lens
- Press the green button to set the shutter speed
- Focus and shoot

BTW, you may have to set the focal length when switching on the camera.
Best regards
Terry

Welcome to the forum.

If they are Pentax K mount (bayonet) lenses they will work with your new camera. M42 screw mount lenses can also be used with an adapter. If they are older K mount lenses designed for the Ricoh camera, you might have a problem with a pin that gets stuck somewhere making it difficult, but not impossible, to remove the lens.

Your K200D manual has a page of limitations relating to certain lenses, but they are minimal and should not cause you any bother.

If you intend buying any more lenses, I'd stick to A series or later. They are the lenses having the A mark on the aperture ring. Using older K and M series lenses might result in some metering/exposure issues.

I have to disagree with terje-l. Set the lens to A and set the aperture on the body. This might be a different way of working for you but if you set the aperture on the lens, you'll have the same metering/exposure issues that you might get with the K and M series lenses.

If you must set the aperture on the lens, make sure you set the appropriate custom setting on your camera to use it. It's turned off by default.

What a crime to see these beautiful old lenses shelved because of misinformation.

I've learned to let this forum be my salespeople - or refer me to reputable shops.

Keep SRS in mind.

You'll certainly enjoy your new body and old glass - I sure do!

Cheers!

Mannesty,

My little piece of advice was ment for manual lenses, without an A setting, as a "quick and dirty" way of getting started. Sorry I forgot to mention item 23, Using aperture ring, in the Custom Setting menu.

I have used this method with an old 1.7/50mm Ricoh lens on my K200D, and the exposure seems to be just fine.

Knowing that the Pentax P30T has the K/A bayonet, I assumed that the OP's old lenses would fit the new camera.
Best regards
Terry
