Protection Filter

[fivegallon]

Without starting a filter/no filter debate, could someone offer advice on the following please:

I have just taken delivery of 2 new lenses; 50 1.4 and 10-22 3.5 - 4.5
My current work location will subject them to some ordinary weather conditions -
South Korea
Temps around -10C to +15C
Occasional Snow
Reasonably regular rainfall (but i don't plan on standing out in that to take pics)
Located in Shipyard (wind, spray, dust and other debris from ship/rig construction)

I am after filters for protection only

Any help appreciated

*If* you're gonna use filters, buy the best you can afford. Multicoated, the works.
B+W or Singh Ray come to mind. No use in sticking a $20 piece of glass in front of a $400 lens.

What René said - buy the best you can, make sure they're multicoated. Heliopan, B+W or Hoya are top of the line.

Better to muck up the filter than the lens. I would imagine there's all kinds of nasty particles drifting about in a shipyard.

I'd place a B&W clear screw-on filter on 50 f/1.4 outright, permanently.
When it comes to the 10-22, I believe Canon would strongly recommend the same be done.Have you checked the 10-22 manual on that ?

I can't comment on the Singh Ray brand as I'm not even sure I have ever seen one. But, sticking with what I do know, Heliopan and B+W are, accross the board, the best for several reasons. Just a couple would be that they both use glass from Schott (Zeiss). I would be suprised if you find anyone who thinks there is better glass available. They both use brass rings instead of the more common aluminum meaning a stronger ring that dosen't seize. They both 'cut' the filter glass from a 'cylinder block' of glass that has been 'dyed in the mass' while many filter companies pour their's in a mold much like plate glass.

Thanks for all the replies (delay response from me due to time difference -- Perth, Western Australia)
Pet-Kal...yep, went through manuals for both lenses (although the one for the 50 could hardly be called a manual)
There's no 'strong' recommendations in the manual but there is the following:

"You can attach filters to the filter mounting thread on the front of the lens"

"if you need a polarizing filter, use Canon's PL-C 77m polarizing filter"

I'll be taking everyone's comments on board and getting the best available - money isn't an issue. Both lenses are already "hooded up" ;)

I've been researching filters as I want one for dirt track racing to help protect the lens from dirt and debris. Someone in the sports forum...wish I could remember who and the post...recommended this Hoya Filter.
