Buy Sigma at your peril. I have a Sigma lens (which I haven't used for years) which works with a Z1-P but not with an SF-X. Why? Who knows?

The focussing ring on another Sigma lens (bought new) is attached by means of double-sided tape. Not a screw in sight. I discovered this when it refused to focus properly.

Some people claim that Sigma lenses are OK, and perhaps the more expensive ones are. But the cheaper ones are best avoided.

Pentax have not yet stated what aperture the 200mm and 300mm lenses will have, so it is impossible to forecast the price with any certainty.

However, in my view the 200mm will most likely be 1:2.8, and I would guess at around 1:4 for the 300mm, in which case expect a price of around £1,000 to £1,500 each. If the 300 is 1:2.8, take out a second mortgage.

DA lenses are digitally optimised lenses for the smaller image circle of the DSLRs. D FA lenses are digitally optimised, but will fill a 35mm frame, and can therefore be used on film cameras. Remember film?

Both these lenses are likely to be of the very highest quality, and, as I have said elsewhere, I would expect them to have in-lens focussing.

How quickly one has to eat one's words. I have just read elsewhere of an interview given by the head of Pentax's imaging divison (I never knew image was a verb) in which he says that a flagship model is being planned.

Pentax have not breathed a word about a K1D, and I for one very much doubt it will happen within the next four years. They would need to have a much larger market share before a K1D would make sense.

And why lust after features you wouldn't use?

Samsung do not own part of Pentax. This is a technical partnership, and since they got together Pentax has announced a raft of new models and lenses which have set the photographic world alight.

I very much doubt that we would be seeing the K10D now if it hadn't been for the tie-in with Samsung. And the low price is only possible because they expect to sell much greater volumes.

I'm all for it, because without it we would perhaps be looking at the end of Pentax.

I curse the choice of focus points, because sometimes you can inadvertently switch to auto.

Moi aussi.

"K series digitals" ???????????????

Jessops are often criticised. Unless the criticism is unfair, it cannot be termed malignment.

It was of course the Olympus OM1 that inpsired Pentax to make the MX and ME.
