The original batteries as supplied with the K-x are superb Lithium cells. Just buy something similar and you should have no problems. They lasted by brother-in-law about 1500 shots over several months.

It's an interesting development. Ricoh have always produced quirky cameras and not been afraid to move into unusual design concepts. The Q should delight them, as will the very solid expertise of Pentax in DSLRs and lenses.

There are several different camera types within the Pentax range of the last few years. If at all possible I would not mix camera types - in a wedding situation this may cause mistakes to be made. There's enough stress in weddings without getting muddled with equipment.

I would team a K-5 with another K-5, or a K-7 if that's not possible.

A K20D and K10D would be OK together.

A K-r and K-x would match, and probably the other single-control wheel models would fit in here as well.

Billingham suply a variety of very fine inserts that may be suitable.

Dust and debris gets into a camera when lenses are changed, but is unlikely to be coming through the weatherproof seals. It could enter through zooming non-sealed lenses as air pressures need to be equalised and there is free movement of air.

The weatherproofing works just fine, so don't let that be a worry. It is a matter of degree though and weather resistant is not the same as waterproof. Also, only the DA* lenses offer dust resistance as well.

If you have a fault, then back under warranty is the answer.

It's a work in progress, so no answers yet. Of course the 70mm has Quick Shift, which is always useful. It is also much smaller. But then again it's much slower than the FA 77mm.

Well you know how it goes, "You're the fifteenth person today I've explained that there's no demand for longer Pentax lenses..." but to be serious, all the Pentax 300mm lenses were high grade optics. Buy with confidence.

Photobucket seems easier than Flikr and there's no quality issue involved really. A digital file is a digital file, wherever you store it.

The other real alternative is for her to post a picture a day on ePHOTOzine. That's free unless you want the e2 membership and it's both easy to upload to and easy to view for everyone.

Yes, that will be interesting. I'm looking at the three Limited lenses this week and I've been out and about shooting pictures, lots of pictures. No conclusions yet!
