f18 is overkill and will reduce image quality through diffraction. And is unnecessary, causing you to need a higher ISO/slower shutter speed than you would otherwise.

Try f8-f11 instead.

WB is to do with how warm/cold the light is.

I assume you actually mean exposure? Setting the exposure manually is a good idea in challenging situations, such as shooting into the light. But you can also dial in exposure compensation, or use the exposure lock to fix your exposure when the camera is pointing at the ground, then recompose to include the sky before shooting.

I tried a NEX camera, which was fun with Pentax lenses via an adapter, and had a 16mm pancake which made it pocketable. Made a nice light kit for holidays (I tend to go hand luggage only).

But the RX100 is a revelation. Genuinely competes with DSLRs on quality, tiny size, sharp f1.8 lens. The NEX seems a bit pointless now, although still has its place for using fast MF lenses at wide apertures (excellent focus peaking).

Having said that, there are still times where I will grab the K30 and 17-50 lens for casual snapping. It's just so much more engaging to use.

€2000 would be a pretty good price (too much for me but if I was a serious photographer, I'd be sorely tempted).

The 24mm version is more usable for landscapes, and is a cracking lens.

Brilliant! Looks like a fuller eclipse than last time too. And the sun relatively low in the sky at 9.30. Can't wait! Thanks Gwyn!

Ah, I see - apart from their really popular model, which costs three times as much as the Q7 and is ranked 23 places ahead of the Q7, apart from that, they're not really selling much. OK.

Whatever happened to poor old Sony is they became the market leaders of mirrorless cameras, as shown further down the article. Do they even still make SLRs?

Doubt it'd be worth existing users upgrading (I've never understood why camera users seem to think they ought to upgrade with each new model anyway), but they have to keep the GR offer up to date with the competition. Wi-Fi, touch screen, and new sensor sound like they will achieve this. Flip out screen isn't mentioned but would be extremely useful.

They mention a completely new name. Wonder if the new model will be Pentax branded? Would make sense...

That viewfinder prism does look big! Hopefully in true Pentax style it'll offer a really good view - better than the D800 viewfinder, which is only 0.7x magnification. I doubt they'll match the Pentax MX's 0.95x viewfinder, though!
