Page 208 of the K10D manual indicates that the camera supports Power Zoom.

I would expect the lenses to be compatible - if they were not it would be very unlike Pentax.

Just a thought - when I am using these old cameras with their -1 doptre eyepieces I use my computer screen glasses (aka reading glasses) which are perfect to focus with.

The viewfinder image is around 1 metre distant optically, so if you can focus on that distance then you will have no problems.

These are the correction lenses that clip on the eyepiece, and the fitting is still the same after all this time. So they will fit both your cameras fine.

Diopter Correction Lens Adapter M is still a current Pentax item and is available in values from -5 to +3. These are listed in the instruction book for the new K10D, and you can't get much more recent than that.

Your Pentax dealer should be able to order these for you. It's also worth doing a search on eBay.

Very nice picture of Clovelly. The treatment is perfect for the subject.

Yes, but by the time you get it back home it's all melted....

We'll still be going to Focus - there are more things than Pentax that we want to look at, in fact we probably have everything Pentax that we need.

Sue and myself will be there, probably Sunday or Monday.

Well this issue Matt beat me hands down for number of pages....must get typing again....

There are a high proportion of enthusiastic amateur photographers, fledgling wedding photographers, University students on long local courses, all sorts of intelligent people. Some know a lot about photography, some very little, but then again some customers won't know much either!

If you think of a chain like Jessops as 300 different shops, then it's not surprising that some will excel and some will not. If they all had a different name we wouldn't bat an eyelid at the ones that fail, nor would we tar them all with the same brush.
