csmonte, it really depends on how careful you are. Hoods and filters at the same time is rather like belts and braces. I prefer using just hoods as I tend to be careful, but I do have a few UVs which I do put on when I know the weather is bad and I want to stop dust/sand/rain from hitting the lens directly.

If you know you can be careful, then the investment into more interesting filters could be worthwhile - look for a close up filter, perhaps a +3 dioptre and see what fun you can have. I'd recommend that over a UV filter for every lens. Just have a UV or two and then rotate them onto which lenses you are carrying on your trip. I seldom carry my full kit unless I'm being paid to photograph and just need that extra kit to hand.

well I'm not seeing any coatings on these. What do you think?

The kit is about the same price as just a polarizer? But then again, if it sucks, what's the point.

I would stay clear of essential kits like that, even though Tiffen is a respectable brand. Spend money wisely - you've invested in a decent camera and lens combination - why spoil it by going so cheap with your filters?

That's just my thought.

I agree with the dust, rain with the UV, many times the sky or environment looks good when conditions aren't perfect. and I feel like I'm pushing my luck with no protection but I am very careful with my camera.

as far as the close up filters, I haven't really figured out what they are and when I should use them, effects and such. I know there is a handful of filters out there, just trying to figure out what the basics are.

Looks like amazon continues to have the best price on the Canon 50mm 1.8 @ $75+ $7 to ship. I'm making sure to support the site.

Ever wondered how circular polarising filters work? Probably not but the section "Polarized Light" near the top of this page has a fairly straightforward explanation.

I'll risk going even simpler by summarising and saying that it is a linear polariser (similar to those used with some sunglasses to cut out glare 8) ) immediately in front of a gizmo which converts the linearly polarised light into circularly polarised light. The point of doing that conversion is that sensors such as are used in a camera's autofocus system need unpolarised light to work properly and they can't tell the difference between unpolarised and circularly polarised light. :idea:

Yes, definitely off the subject - so I've posted a reply in the appropriate thread here: http://www.cameralabs.com/forum/viewtopic.php?p=23273#23273

Hope that this helps.
