As Ken says. It's am amazing little camera that does actually offer something different - true compact portability and high image quality.

Yes, thanks, it's of interest. Ricoh seem to have managed to push up their market share of CSCs by 1% by December, which is good.

It's also clear that DSLR sales may be declining, but still have by far the largest number of sales.

Yes, five was a bit thin.

The mismatch has been happening for a while and is known about.

To be fair, the closing dates are well known by now. End of the week and end of the month as appropriate.

Whilst it's true that older wide angles will not be telecentric designs, that doesn't mean that we can't use many of them with perfectly satisfactory results.

In terms of mounting and the physical connection of Pentax lenses, we can assume that almost all Pentax lenses can be used on the DSLR range. I would not discourage anyone from doing this, because some of the lenses prove to still be quite excellent. We are also using only the centre of the FOV of these lenses, so that helps.

I'd also mention that several of our best current lenses are in fact from the film era - the 50mm f/1.4, the 31mm, 43mm and 77mm Limited lenses.....these last three still out perform most current telecentric designs.

The other thing to think about is the intended purpose of a lens. Even if we had a really "bad" lens, it just might be the perfect portrait optic. But there are no really bad Pentax lenses.

I think in the case of the Pentax range, we don't have too much to worry about.

Thanks for the link, looks like a very nice new lens.

Maybe a non-specific request is the problem. A little bit more information might be more encouraging?

It would be interesting to see how Pentax shutter/mirror assemblies behave. They have always been presented as having very well controlled mirror and shutter bounce. Horizontal cloth shutters would also be interesting.
