No, the actual focal length is marked. A 16-50mm lens on a Pentax DSLR will show the same field of view as a 24-75mm lens on a 35mm film camera.

Hope that helps!

All pentax lenses can be used on current DSLR bodies. Anything from the A series or later will work fully as expected. The key is having an "A" setting on the aperture ring so that the camera can control the aperture.

Earlier bayonet K fit lenses can still be used manually with some limitations.

Screw thread lenses can also be used with the Adapter K, manually.

Nobody is getting at you Charlotte, just having a wider discussion that was prompted by your thread.

It looks like it, doesn't it?

I shall one day pass the mantle to my son, and thus will the task be handed down over the generations.

I know it's enough to make anybody wince, but here is a progress report on my Project Decay. Image 19 shows the camera really becoming cemented in by plant growth, and no doubt it is now home to a fair selection of small creatures.

It's still looking pretty good though, a very impressive pereformance. Here's Picture 1 followed by the current Picture 19, shot yesterday.

I have no doubt that somewhwere the phrase "does not affect your statutary rights" will be found. Which basically means that the law of the country (of purchase?) will stand, as obviously it must.

What happens if you buy in Japan but live in England I don't know, and Amazon is rergistered in Luxembourg.

It's all a bit wooly really, but don't forget that after six months the onus is on the consumer to prove that there was a defect from new.

This might be possible with, say, the sensor stain issue. Lots of corroboration could be printed off from the internet. With some other faults it could be well nigh impossible to prove.

What I have thought is that it really pays to start off by being courteous, whereas more and more people seem to think that the starting point is to go in with guns blazing.

David has asked one critical question. The other is what is the output for?

If for the web, it doesn't matter much. If for posters in a huge rail terminal, then maybe it does.

I don't think resolution will be so high as to make any particular lenses redundant. But just as the 18-55mm was upgraded to meet the requirements of new sensors, we will reach that point I think quite soon.

I'm not sure how eactly it works, but there is a double cable release that makes part of the process possible. I presume this attaches at the lens end and the camera end of the bellows but is released by one plunger.
