I tried the Sigma but liked the Pentax 10-17mm more, simply because I like the fish eye images. I ended up with neither. As much as I would like to own the lens, I could see me using it a lot to begin with and then struggling to find a regular need for it. Anything new coming in has got to justify its acquisition. I'm still working on a good long term reason to get the 10-17mm though!

Well, I added my never to the poll. Despite my somewhat negative feeling towards video being included in my DSLR, I've put making a short video in my photography 'things to do' list for 2015.

I'm pleased that someone has asked this question. Whilst I'm certain I'd be impressed with the abilities of the video function, it's something I don't have any real interest in, and would have been happy to have had an option to buy the camera without this feature at a lower price. Do video camera manufacturers made a big deal about the single image capabilities of their products?

At the local river, I see no end of bridge camera owners shooting video of the ducks and narrow boats, but I've yet to see any DSLR owners do the same; I've got to the stage of looking to see if a DSLR is being used that way.

My view in time over this may change, and as it is there I might be tempted to use it at some stage in the future. I suppose I'm curious why so many camera reviews bang on about the video features and I'm left thinking that I only wanted a camera, and my own group of friends feel much the same way.

Just a small observation from a new poster, but long time reader of the forum.

I own a K3. As a hobby photographer, I agonised long and hard over the various reviews and videos on the internet before buying, and I moved up from a K7. For me, there had to be clear water between models in terms of improvements and refinements. If I had any of the K5 models, all fine cameras, I'm certain I wouldn't have upgraded to a K3 as there is some clear feature overlap.

I used Pentax film cameras for decades, and swapped to an ist D sometime after it was launched. I traded that in for my K7, and that was a giant leap and an easy decision, both for features and the feel it brought, and it was only at that point that I felt I was getting back to what I had lost with my film LX. The K3 is an upgrade, but not a leap from a K7. In recent years, the introduction of a new model has never made me reach for my cheque book, and this time round, I've retained the K7, as it is still a very usable camera. I will admit to liking the K3 grip more and that alone has been worth the purchase!

I have no idea if a later model of the K3 is planned or, assuming they use the same name pattern, a K1 - but it will have to offer a significant difference and improvement to the K3 for me to sign up. As I tend to use the cameras manually mostly, that's quite an ask.
