Need Some Help On Lens Compatibility

I have just purchased a Pentax K110d and have been offered a Tefnon 70-162mm zoom lens which apparently has a KA Mount. Presently it won't fit and I wondered if there is an adaptor about that can be used? I'm new to photography so please excuse my ignorance. Any help would be appreciated

The best advice is not to buy cheap, third-rate lenses, especially if they will need an adapter. That means they won't work properly, and will have to be used in manual mode.

Look on Ebay for second-hand Pentax lenses. The SMC Pentax-F 70-210 1:4 - 5.6 is a superb lens, and can usually be bought for £50.00 or less.

Sadly this one has been sold, but another will be along soon:

Incidentally, if it had a Pentax KA mount, it WOULD fit, so clearly it doesn't, or does. (Have a KA mount/fit.)

Thanks for the advice George, I was offered the lens free and just wondered if I would be able to use it with an adaptor. I suppose I should try to sell it on ebay!

Well, I think the owner knows the value of his lens.

I doubt if you could sell it. You don't know what camera it fits, and few people have ever heard of Tefnon.

What I do with no-name lenses is take them apart. At the very least you'll end up with some nice magnifying glasses.
