All faulty cameras have been replaced, so I wouldn't expect anything more than that could be done surfseen. Don't think that batch faults are exclusive to Pentax, because they are not.

Nikon and Canon have both had their own problems. In the case of Canon an entire lens production run had to be replaced. The returned lenses were, I hear, destroyed to prevent them re-entering the supply chain. Sounds a pretty drastic situation to me.

There will still be faulty cameras here and there because not all suppliers will have returned them, so residual problems may crop up from time to time.

If you're really happy with your K-r, then surely your personal experience is totally satisfactory?

The stats seem fine.

I was thinking that in Victorian times it was very common to see collections of letters published. These were written, of course, by Men of Letters, when writing using quill and ink was The Thing To Do.

I wonder why I haven't got a queue of publishers clamouring for the rights to the "Collected Forum Posts".......? Ah well, maybe I'll have to find another path to fortune.

Pentax specify the depth and duration, the latter being up to 2 hours. They also specify that seals must be replaced after I think one year. So an annual service looks likely top ensure they remain waterproof.

Please don't post subjects twice in the forum. You'll get plenty of answers in your original thread!

No, I don't. I got one for Sue (Mk I version) and one for my brother-in-law Mark (Mk II version) and I've decided I would like to join in with their efforts to master bird photography!

Whatever would I do with three identical lenses? Stereo shots with the left hand kit and standard shots with the right hand perhaps...

Just noticed this but have a couple of moments ago sent you a PM.

I get it, you can be sure, but why be silly and ask for something that's going to price us out of the market? It's merely a commercial arrangement, so we need to be in the right ball park or we won't get anything. Where's the profit in that?

It's all very well seeing it as some sort of capitalist conspiracy or horrendous cheek, but of no benefit for us to do so. It just raises the blood pressure. And the organisation in question won't even notice.

The problem usually comes later when a new body is introduced and the Sigma lens has to be re-chipped. It has happened in a few instances and in severe cases has been impossible to do. Minor problems include misreporting of the lens in the EXIF data.

It looks like quite a few are more than willing to reveal their ID, whether or not it's a good idea I'm not sure.
