Thanks Gareth, it seems Barry is a place not a person....ah well.

I can feel that very much dcweather, I spent quite long enough looking for moire!

You can only upload one image into a competition, so once you've done it the option disappears.

If you haven't uploaded one yet into the Monthly competition that should still be possible. Click on the competition name first.

Don't forget images for the monthly must be shot in November 2013.

I guess there's a lot of vibration with a bike, so maybe a small backpack could be the safest option?

It's always worth mentioning PeteL. So far, nothing obvious as a root cause for this sort of thing has leapt out at us. The instruction manuals mention static, but that's about it.

I did idly wonder if battery voltage might be a factor, but I've no evidence that it makes any difference.

For me Tom, the only problem is justifying the £2000 it will cost for two of them, his and hers.

If we do a wedding, we can't have two different levels of definition in the images depending upon who shot what. They have to be the same.

I can see a major flaw in those figures. They are tested in conjunction with different camera bodies and really they need to all be re-tested with the new K-3. My concern with current lens testing is that it tests the whole lens/sensor combination rather than just the lens. So as cameras improve the whole performance of the lens might change as a result.

Lenses have a character as well as technical results. It may also be that some excel at distances that are not conducive to photographing test charts. It could also be that an ideal portrait lens, for example, had relatively poor definition. Our subjects might appreciate it.

There's much more to lenses than lens tests, just take it as one aspect.

There's not a lot not to like about the K-3. There do seem to be some differing opinions about the AF though. I agree with this one that it's fast, but AP seem to think it's not slow but not that fast. However, they were trying it with generally slower lenses.

I think also it may well depend on the settings used. We can choose focus priority or release priority and I would always use centre point only. Others will have their own preferences.

You might well feel dismissive about it Barry, but I can only report what I find. However, what you say is not entirely accurate and I have had umpteen failures from ME series cameras, all electronics faults. And an *ist film camera that failed prematurely and a K10D that failed but was repaired quickly enough at a reasonable price.

But I have never had a lock up and have never felt the need to fine tune the AF on any of my lenses. They are all Pentax lenses by the way, apart from the Tokina 80-400mm.

Can't be helped I'm afraid, luck has little to do with it, I suspect it's the norm but we usually only hear about faults. People rarely post to tell us nothing is wrong!
