All this is very well, but it should be clear that the OP does not have more than a very basic knowledge of computing. Following this increasingly esoteric advice would likely be a total disaster.

Even the suggestions of what is basically "needed" are way over the top, when what is really needed here is just about any commonly available laptop or desktop machine.

It isn't even necessary to upgrade Windows XP....

SteveF is correct, only the monthly is time constrained. That's because the membership wanted such a competition, not because it was imposed.

We don't generally link to auctions nass, maybe if it's BIN, but people get iffy about potential bargains being flagged up to us all! There are 5 available on this one, BIN, so that gives a few people a fair chance.

No, the original K series cameras (K2, Kx, KM) wewre released alongside the original K lenses, just marked SMC Pentax.

The M series cameras (starting with the MX, ME) had a new compact range of lenses marked SMC Pentax-M.

The A series cameras (Super A onwards) needed electronic contacts and were accompanied by lenses marked SMC Pentax-A.

Hope that helps!

Camera clubs/Photographic Societies do vary quite a bit. It depends very much on the people concerned. Some are very welcoming, some are like intruding into a private conversation, and all things between of course.

Competitions have a place, but if there are too many it does get brather samey. At their best they encourage people to up their game. At their worst it makes people start shooting for competition and they can lose sight of their own creativity.

I enjoy competitions as another way to get images out there to be seen. What I shoot, I shoot because I want to, not because it's a "competition shot".

Title corrected.

A report or PM is fine, we get spammers all the time though and they will get noticed.

Some only last minutes, some survive a little while till we check again, but they all go the same way - delete, maximum delete....

Exposure is affected because the water absorbs the light, so it's darker down there. Red is absorbed quicker, so everything tends to look blue.

I've pointed out the price list problems and it's being corrected. No con, rather an oversight in a very, very busy environment. It will get sorted as soon as possible.

Fitting a lens to any Pentax camera should be smooth and totally free of problems. If this one doesn't fit, then I would suggest it should not be used.

Are you sure it is PKA and not some similar but not compatible bayonet?
