Use gloves

Don't know Tobio, I'm not even sure the dishwater hasn't have any negative effect.
There is also the weatherseals you need to think about.

Well the K10D has weather-sealing so I thought it would be okay
I said I would give some here an heart attack

This answer all your questions I think link (Pentax is named so that makes any article good)
Only bought a filter for protection for my first two lenses but not any more, actually my uncle now has the filter.
I only use polarisers and square GND filters because of their effect.

I simply use very diluted dishwasher and use that to make a cloth slightly damp when it feels greasy. The dishwasher is make to remove grease so that works perfectly.
Most likely I will cause some heart attacks again by my cleaning methods

No it will not work with your K10D so leave it alone so I can buy it for my K10D

All Pentax lenses will work on your K10D so no need to ask.
This an A lens and that means it will have an auto-aperture which is very good because you can use all modes on your camera (Av, Tv, ect) however the lens doesn't have autofocus.

Don't know if the price is good or not, I think it depends if you get any warranty or not.

btw, it's said this lens works very well for macro stuff when you've extension tubes or reverse mount the lens.

edit: seems like it's a good price

Too bad
What's the problem?

Yeah I like that bag very much, it's looks like it will fit the two DA* lenses and a flash perfectly but for long walks I'm actually looking at a rucksack.

Oh yeah the Hadley looks very nice but I like the f/1.4 stop better but that's difference in taste more likely

I've a big Crumpler bag but it's very heavy for one shoulder when everything is in it. Also the quality of the Crumpler is pretty good, I find it better compared to the lowe bag I've.

I´m now looking for a bag for the camera and the two DA* lenses and a flash so slightly smaller then what you're looking for although not much.

Do you want a shoulder bag or a rucksack?
