I probably won't bother. It works after a fashion and I only thought I'd give it a try because I've just bought a couple of cheap lenses for a couple of my other 10MP cameras and didn't want the K10D to feel left out.

The problem is easily solved - I can focus on the K10D screen easily (I started out with a Zenit 3m - plain screens don't scare me :wink. Unfortunately, depending on whether I am wearing my glasses, which pair (reading or distance) and how the correction dioptre thingy is set, what I see as in focus and what the sensor sees as such may not be the same thing. Anyway, an hour or so with a fixed target, a tripod and careful notes about what was used should give me the answer to that.

The question may be more important. The lens seems to work fine in Av mode - slightly underexposed, but otherwise OK. However, the aperture ring will only turn from 1.7 to somewhere between 8 and 11. Won't go as far as 16, 22 or A.

Is this normal, or do I have a real problem?

ETA: Solved. The lens has a problem. I took it of the camera and the ring won't turn past 8/11. Oh well, it seems to work OK otherwise.

If you search on "Carl Zeiss Jena Visionar 183 mm f/ 1.9 Lens", you'll get some hits. I think the Rathenow is a licensed version of that.

Nor me - I use Copy/Paste.

That way there are two copies of the file. Well, the original and a copy...

Perhaps you should be glad not everything makes it out of the far east...

He's not a member at that other place anymore either...

You wait till they start introducing mkII-only firmware updates...

No 4 for me.

But then, I do have a bit of a thing about railway infrastructure...

Internal battery/capacitor (not sure which Pentax DSLRs use) needs looking at?

Hmm, with respect to this thread and a couple of others, I compared the Ricoh-Imaging UK products page with their on-line official store page. There's a lot more items on the former.

Whether this is because
1. they can't (for some reason) get the items in question - about to be dropped or
2. they could, but don't see the UK as a market worth putting much effort into or
3. they can't be bothered updating the page(s)
I don't know. But it does make me wonder...

Just noticed - the store page is EU, not UK. Don't know how that affects things.
