I see the main problem as being some subjects that are not written in stone but have various points of view. The advantage of the forum is that these things can be thrashed out, enabling newer members to see all the issues involved.

There are plenty of info sources on thw web that purport to be factual, and some are good.

Have you read through the instructions for posting pictures at the top of the Your Photos section?

Tricky, as polarizers will not affect reflections in metal.

You might have to resort to photography though a large white sheet, with a hole cut out for the lens. Or change your camera angle to include better (!) reflections, or use a longer lens so the size of your reflection becomes less obvious.

The input of focal length is asked for when a lens it attached that the camera does not recognise. This might be an older manual Pentax lens or perhaps another make of lens altogether.

Pentax AF lenses will almost never ask for this input and will recognise the lens automatically. This is for the purposes of the SR mechanism.

The GX10 and K10D are the same, with some minor differences to the menu system.

First you need to get to grips with the camera and its kit lens, which may be the 18-55mm? When you have used this for a while you will start to realise what should be the next lens. Perhaps you'll find that you like shooting sports or wildlife, so you might want a long lens.

If studio portraiture is your thing you could look for a fast 50mm, although TBH the 18-55mm will serve perfectly well for this also.

Perhaps a wider lens for architecture and landscape? And so on...but first, don't dazzle yourself with too much information until you feel comfortable with the camera and its supplied lens.

Thanks Jonathan, you've highlighted some important details there.

No doubt the 30fps is related to the frame rate in countries that use 60Hz mains supply - the USA and possibly Japan. So it's not really a feature that needs maintaining as such. 25fps is the UK video frame rate, because we have a mains AC frequency of 50Hz.

Way out i think. The focal length of lenses does not change, only the amount of the image circle that the sensor sees.

For the same pixel pitch a FF frame sensor would have to have a higher pixel count than an APS-C one, simply because there's more of it. Or the pixel count could be the same and the individual pixels could be bigger. This latter scenario is where the lower noise comes in. Bigger pixels produce more current and have less inherent noise and less overspill between pixels.

Once you start to load that up it will be very bulky and unwieldy. Not for me.

A Billingham Hadley Pro does me just fine for 99% of the time. Nothing needs to be unzipped and access is rapid without having to put the bag down. I have dozens of other bags should I need them as I can never resist them....

I'm still not clear exactly what happened and when. This wasn't amidst all the snow was it?

Are you saying that delivery was 2-3 days from their confirmation of order, was the confirmation itself delayed?
