UV Filter

[Deleted member 11679]

Ok, I have heard a lot about people saying you 'need' a UV filter for lenses that are being used outside for the majority of their time/being used where the sun can really get them.

First off, is there a general opinion that having a UV filter on a lens will protect this and is in fact necessay?

Secondly, If I were to get a filter for my 70-200 F/4 L, which has a filter size of 67mm, I have a step down ring to make a filter size of 62mm work on this lens - which apparently makes it cheaper but is it also worth it? (I was given the step down ring by the guy I bought the lens off.)

Thirdly, what type or brand of filter is recommended? Obviously it needs a UV one, which is the one I am looking at...but I am struggling to find any Canon ones or do they not produce them? Is Hoya good?

So many questions! A little clarity to the situation would be muchos appreciated.

It can be a bit of a pain losing 1stop or so, but digital means its easily sorted with a quick ISO fix.

Does that apply to every filter I attach? I lose 1 stop automatically?

warning, controversy ahead!.
There are pros and cons to using UV filters - I'm not saying people should, shouldn't use UV filters, but I do think people should realise the downside as well as the up. this article makes for good reading.

Very interesting reading. I may hang tight for now, if I go on holiday to a very sunny country for instance then I will definately get one, however in the UK the odd sunny day I cannot see doing loads of harm. I also think I will be a regular user of that lens hood that comes with it as well.
