I reckon it's worth £100 or so, maybe more if you really want it. It's PKa mount so no messing with manual stop down exposure on your DSLR.

I would be interested if I hadn't just found the Tokina 80-400mm zoom in PKa mount, which I'm trying out first.

400mm lenses are much in demand in Pentax fit and not very common, so the price could do much better than we expect.

Dropping a lens can cause lots of problems and it sound like a very substantial repair, if not in parts then maybe in time. If the job took three hours, for example, that would probably be £90 or even more before any parts were used.

If there's no chance of an insurance claim, then I would just replace the lens. Even when repaired you may have a risidual doubt that it's quite as sharp as it was before, as slight distortion of the optical components may be hard to spot and would be pointless trying to replace in a cost effective manner.

Well the K20D seems to be at the end of its run, so the chance won't be there for much longer.

There's no answer to the question though, because it's too soon to know where the K-x will end up in the scheme of things.

It doesn't really stress me to be honest as when I look at the next upgrade it will probably be the K7 when it gets to the end of its life cycle.

No idea yet - it will all depend on the final "street price" and that takes a short while to bed in.

The K7 is now settling at under £1000, very competitive with the Nikon D300s.

"Recommended retail" prices are always a bit unrealistic.

The *istDS is a great camera, we quite miss ours in a way.

The image is measured in ppi (pixels per inch) and the printer prints your image using its inks at a certain dpi (dots per inch)

I know it might seem pedantic, but getting this distinction right will help to avoid confusion when tackling the mysteries of resizing in Photoshop.

You can and you can't. The lenses that can be used are quite restricted as are the apertures that they can be used at. It's not the same sort of universal compatibility that you get with Pentax and, to almost the same degree, Nikon.

20mm f2 would be a bit optimistic I think.

I have to tell you that when I tell our cat about this, she will be very upset....

So very few of them look happy with what they're doing, it can't be good!

I shall stay at home with my computer and a glass of wine and enjoy your rather nice pictures intead.
