The 1.5x crop factor. It will always be a 70-200mm lens, but the APS-C format is smaller than the 35mm film format. Consequently, a lens will show a reduced angle of view. The 70-200mm will show a field of view similar to using a 105-300mm on a full frame camera.

A superb lens, snap one up!

I think we can match the various options with our general requirements. For example, I need weather resistance, so that in itself cuts out some very fine models. In terms of shooting pictures it would make no difference, but shooting a wedding in the rain it does.

I also need a compact body, so when out and about it's not too onerous to carry the kit. That does lead us naturally to Pentax in general. I need excellent JPEG output, so Pentax again. Compact lenses, Pentax.

High quality of construction and of image quality goes without saying, Pentax again.

So most of the requirements for me can actually be met by any Pentax DSLR, the proviso being the WR and the ergonomics of the particular model. And the cost!

Will I go for FF, well who knows. When the time comes to upgrade again, I'll have the choice, but it will depend on my needs at the time and the costs involved. Interesting times!

Indeed, but pedantry apart, green seems to indicate SMC and red HD, so far at least. I suppose these are images of prototypes, so we'll see what the colour coding means when we have the first production lenses.

It's a nice technique to use on the right subjects and you've made a great job of it here.

Absolutely, totally agree.

Photoshop Elements at that price level, without a doubt. If you can go for the Photoshop monthly charge, then the full version is even better.

I'm sure that there will be lots of people still using APS-C that will be looking forward to a bonanza od second hand lenses. Don't dispose of them yet though, as it seems some may well be full frame lenses in disguise.

As for a prime, the SMC Pentax-FA 50mm f/1.4 is still around, as is the 35mm f/2 and the 50mm and 100mm macro lenses. That's probably more lenses, with the new zooms, than Sony started off with, and there's plenty of time yet for more announcements.

There seems to be a lot of activity going on! Pentax have been busy it seems. I'll look forward to seeing this one as well, it seems to have the articulated screen that many have been asking for over recent years.

Imagine that you are looking through your K-7, you see the image at almost life size.

Now imagine you are looking through the new FF, it has a wider FOV with the same lens. The size of objects does not change, but your window has just become larger.

The question now is how does the camera show the reduced FOV when the larger view is the normal one. There could be a mechanical masking, similar to the panoramic mode on some film cameras. There could simply be etched lines on the focusing screen to show the reduced area. There could be electronically projected lines. There could be a hybrid optical/EVF system.

Whatever the solution, the size of any object in your viewfinder will stay the same, only the FOV will change.

If you want to know how big the viewfinder will be, look through a film SLR.
