Thanks, very interesting.

Judging from the experience of a few people I know, the 150-500mm Sigma is not in the same league as the 150-450mm Pentax, so the slight loss in focal length won't be a huge drawback.

Sue downloaded the suite late last night, no problems integrating it into CS5. I might, but there are other programs I already use to achieve what this does, so it's not a priority at this moment.

A rested battery can often recover a bit, so I suppose that one on the verge of changing the battery level indicator might flicker between the two states of indication.

I've not really been bothered by this as I tend to have the camera switched on between shots, so when battery power starts to drop I just change the battery. Better to do that I think than find it dies at a critical moment.

We do tend to hear about faults on forums, but it all depends on how common it actually is. After the first six months it's up to the user to prove the fault was there from the start, whereas in the first six months it's up to the manufacturer to prove there wasn't a fault. The six year rule is there, but it isn't as clear cut as we might like.

I'm regretting letting my 24-90mm go now. Originally I'd thought that the 12-24mm plus the 24-90mm would be great together, but in practice too many shots were around the 24mm point and needed constant lens changing. On full frame it's an ideal standard lens.

I have done lots of shooting with the Q-S1 and my EPZ pages have quite a few examples. I've also done a few blogs using the camera. here's the wildlife one: https://www.ephotozine.com/user/johnriley1uk-22471/blog/the-new-pentax-q-s1-and-...

Data storage won't be a problem, the price per TB is quite low. It wasn't even on the list of things to factor in. I'm much more interested in the ergonomics and efficiency of the camera, plus some other benefits for some things I have in mind.

We are just back from the NEC, so a blog a bit later on, but a decision has been made.

I have just ordered a K-3 for Sue. She loved the K-1 and was very impressed by its speed, although she found it a bit heavy. That would have been OK, but the clincher was that she definitely wants a built in flash. So, K-3 it is.

I will order a K-1 plus the 28-105mm when supplies start coming in. I will go full frame and keep a K-5 as backup. I don't need the built in flash. I was really impressed by the feel of the K-1, it fitted perfectly and was amazingly fast. No difficulty making a decision once held in the hands. Hopefully a review copy might find its way to me in due course, but in any event I know I'm buying one.

That means that soon there will be a K20D and a K-5 body up for sale, both of which are in pristine condition. More of that later!
