Go the custom settings and look for saving image rotation, making sure it is set to On.

In the playback menu also make sure auto image rotation is ticked.

Agreed, really interesting.

We don't all dress the same way, never mind use cameras the same way!

Absolutely right, what I said is true for me and is what I'm thinking about these various ideas. I've also explained why.

The point I was making was that not everybody wants all these things, for perfectly reasonable reasons. As for reviewers marking down, maybe they do or maybe they don't, but as buyers we should be able to use reviews as a guide, see what is said and then make up our own minds.

I thought it said the mount was sealed but the Tokina lens wasn't WR.

It's not clear which design team designed what, but they have been several co-operations between Pentax and Tokina, as listed above. Generally the Pentax version is more expensive, but there are exceptions, such as the 10-17mm which has been a lower price in Pentax.

It looks like an excellent performer and it will be interesting to see how long it is before the Pentax lens appears.

It is interesting how requirements vary.

WiFi and GPS I could take or leave, not a problem whether they are wanted or not.

A touch screen can't be ignored, but I'm not interested in one. Have tried it, found it no advantage at all.

Video? If I wanted serious video I'd buy a video camera. In a stills camera I see it as a handy way to make an impromptu video. Rough and ready but OK in the right circumstances.

Grips? Don't like them, why add bulk and weight to a beautifully designed bit of kit?

Articulated screens? Well I have one on the MX-1 and it's a disadvantage in making the camera more bulky. There may be rare situations when it will assist when grovelling for fungus shots at ground level, but I'd prefer to be without it.

CSCs? Pointless IMHO. The Q series does have a USP (Unique Selling Point) in its diminutive size, but the larger ones need to be carried in a camera bag. If that's the case, it might as well be a nice compact Pentax DSLR.

I rather like the cameras as they are.

Nothing. Never touch the mirror or mirror mechanism. If that gets out of alignment so does you ability to manually focus and see when the camera is focused properly.

In a camera's lifetime you should be able to get by without cleaning the mirror. Odd specks of dust won't have any effect on the image itself.

Mk II version onwards have a revised optical layout with increased resolution to cater for the higher pixel counts from the K20D and later bodies.
