After all what? The message was that pretty much all older Pentax lenses can be used with the DSLRs, but those of the Series or later are more convenient. This does seem very straightforward and you won't find such a degree of compatitbility elsewhere.
What did you choose to do in the end?

Thanks guys. I'm now in a too much information overload.
So unless i'm wrong here?I don't need to look at the letters or numbers that came after the 1st K forget the af or af2,the actual mounting is a k mounting?
Avoid old lenses without an A on the aperture ring (if made by Pentax they will have a suffix of M, or none at all (eg SMC Pentax-M), unless you don't mind losing a bit of automation - you have to use them in manual exposure mode.

Woah sorry guys,didn't mean to start an argument.
I only asked because I thought they might be different fittings.
But for your information, all Pentax K-mount lenses fit all Pentax K-mount bodies, and (with one or two exceptions) all non-Pentax K-mount lenses fit all K-mount bodies.
However, although they will fit on, most modern lenses won't work on film bodies that are over twenty one years old (and the more recently deceased LX) because there is no way for the older body to set the aperture on the lens.
And similarly, some modernish film bodies won't be able to set the aperture on very old lenses.
But any Pentax digital camera will work, with some limitations in some cases, with ALL Pentax K-mount lenses.

The only difference between the KAF and KAF2 mounts is an additional two contacts inside the lens mount. This was added to provide the power for the power zoom lenses. On digital bodies it'll be used for SDM power to the new SDM equipped lenses.
I think that Kaf2 is the same as Kaf, but with the addition of more lens information being transferred to the body (eg: MTF data). The change corresponded with the change from F lenses to FA lenses.
At the same time, most bodies were equipped with the two contacts to supply power to zoom lenses.
Later, these contacts were dropped from some bodies, including the ist series, but that didn't mean the mounts reverted to Kaf. They were still Kaf2.

Hi folks,it's a while since I last posted on here but here goes with my question.
I have the K100D,but i'm thinking of getting the K10D now.Are the lenses I have for the K100D compatable with the K10D,or will I need to get new lenses to use the K10D?
I'm asking this question,due to specs on cameras saying that the K100D is a KAF fitting where as the K10D is mentioned as being KAF2.
The only difference between the two is that the K10D has additional contacts to enable it to use the yet-to-be released SDM lenses (which have a focussing motor within the lens).

For water shots, you may need to put a neutral density filter on the lens because the slow shutter speed will lead to over-exposure unless it is a very gloomy day.
The great thing about digital is that it costs nothing to experiment, and feedback is instant.
A bit like advice on this forum, really.

PS: So get experimenting!

4 Gb SDHC Ultra II card cost me 55 EUR a few months back, they are so cheap now that for my Kenya trip I will take 4GB CFs in my *ist D... just to reduce the critical moments where I have to change cards during a game drive.....
I think 4Gb cards now have the same probability of failure as a 2 Gb....my back up is film...(or is digital the back up to film? )
I don't think this answers Pete the Claret's question....whether it's worthwhile getting a SDHC Class 6 or not... I guess, though, if you are shooting a burst of jpegs with the K10D the camera can keep on going until the card is full, so to me it means if you get the 'better' card the K10D can make good use of it....
I hope I am right...

When I eventually get my K10D repaired I'll tell you what it's like.
The 1.7 is well-regarded optically (like other Pentax T/Cs), but the AF doesn't work that well on long lenses with small maximum apertures unless it's a very bright day.
