As well or as badly as any other lens.

In days of yore, when we used film, we also used filters a lot more. It's not so necessary with digital photography, where most things can be done in post processing. On film we need filters much of the time to correct colour balance or tonal quality upfront.

So, yellow, orange or red filters for black and white and 81A warming filter for colour, for me at least.

We still need polarisers and graduated filters from time to time. In reality, I almost never use a filter these days.

Looks good!

But you don't.....you can access your files with any suitable program at any time. PEF, DNG, TIFF and JPEG are the most likely ones, none of which should be a problem. In what way do you feel they would become inaccessible to you?

Hope that helps!

I would call 600 Euros quite expensive - close on the cost of three waterproof compacts and very cumbersome as well.

I don't feel afraid of using my WG-3 in any circumstances, that's what it's for. If it fails, it fails, but then so could a waterproof housing.

No, I don't think that one has any merit in it.

I understand the original problem, but who can predict what will happen to all the alternative versions to Photoshop etc? Who could have predicted the subscription model when we all using Photoshop 6 or 7?

Nothing in the IT world is certain, but the algorithms that Adobe uses are usually superior to the alternatives. This may or may not matter, but I resisted for a while until I needed the upgrades and therefore had to go with the subscription. IMHO there isn't an alternative that is as good.

I just went for the CC version. I paid upfront for a year and it works out at around £8.50 per month. Frankly as it constantly updates and gives me PS, LR and Bridge it's well worth it for me.

If I want to I can still use CS5, or even CS2 or 7.

Housings are quite exprensive, but a Google search should bring up the various manufacturers. Some do make Pentax housings.

However, how about the Ricoh adventure cameras? The WG series, once labelled Pentax, are nor labelled Ricoh.

Thanks for the website link. Identification is always tricky.
