hi guys - I'm thinking about getting a filter for my 400d - most likely a polarizer...

now, I have to main lenses that I use - my nifty fifty (canon f1.8 50mm) and a canon 70mm-300mm lense....
now, they both seem to be different sized - so, what would be the best lens to buy for initially..?
and what filter, and where from..?

cheers

I will assume that you have a UV filter on both lenses to protect the front surface of he glass. If not get these first.

I am sure that you know a polariser will reduce reflections and also in some circumstances darken a blue sky considerably. It will act as ND filter as well so you get quite a bit for your money

I think only you can say which lens to buy for. What do you usually take pictures of . Which lens do you use most . why do you want a polariser .

The 70-300 lens uses a 58 mm filter and the 50 mm lens a 52 mm filter. You could get the 58 mm size and a step down ring to use it on the 50. That would save some money.

As to where to buy from I got a polariser from Hong Kong for about 50% of the UK price. There are a lot of fakes from HK for things like memory cards and batteries. I assume that you can get fake filters from there as well. I do not know how to tell then apart but the one I have works OK which is good enough for me.

As AQ said - you could buy one to fit the bigger lens and a step-down ring so you can also fit it to the smaller one.

I'd have to ask, like AQ, why you need a polariser. Good for landscapes where you want to saturate the blue sky (but that implies a wide angle), water/plant shots where you want to reduce bright reflections or waterfalls where the increased stops can be useful to slow the shutter (and probably not use the reflection reducing properties!)

cheers guys - basically it would be used for landscape stuff...but I do commonly use both lenses...just wasn't sure if there was a general trend with most of the people on here..!

I haven't got a UV filter...guess I'll need to look into that first..!

anyone got a link to the step down ring..?

cheers

You can get them pretty much anywhere.

I use SRB in Luton.

But remember to take off the UV filter before fitting a polariser or you will get some vignetting.
