Looking to buy my first filter & going for a Cir-Polarizing, I currently own the Nikon 18-70 which takes 67mm but I read its a good idea to buy a step-up ring to 77mm as thats the most common lens size. 95% sure my next lens will be a Sigma 10-20 which is also 77mm. Is that a good idea or will the step ring have a negitive effect?

Also whats a good filter for go for? was looking at the Hoya pro range & the 67mm is £40 & the 77mm is about £80 which seems quite a difference for extra 10mm,
 
You won't go wrong with the Hoya Pro 1D range but as you've already seen, it's expensive. I would have thought that if you get the 77mm and step up ring you will save yourself the best part of £40 and it sounds like a good idea if you're getting the 10-20 in the near future. I'm not familiar with step-up rings and their affect on smaller diameter lenses but in theory it shouldn't make any difference to your images as long as there's no vignetting. I think that's probably the biggest issue but as I said, I've got no personal experience.

I was in exactly the same position as you. I had the Nikon 18-135mm (67mm thread) and soon after I bought the Sigma 10-20mm.

I went with the step-up ring route, but I semi-regret it. It's just extra hassle. Maybe you should go for the normal HOYA filters which are cheaper (and probably almost as good) and buy both.
A step up ring is going to be £5-10 anyway by the time you've got it (I got mine from the auction site).

What's most annoying however is the fact you can't rotate it with the hoods on (argh!)
When will lens designers catch up on this??
 
Can you really warrant paying almost £100 on a filter?

I just got a circ polarizing from the well known auction site. Bog standard hoya for 23 quid, i cant imagine there being a massive difference between the two.

Another way to look at it is why pay say £500 for a lens, then put a £20 filter infront of it to make the image nice and soft?

Are there such things as fake filters floating around on the auction site as some of them are very cheap?

If you buy from a reputable auctioneer then I don’t think you will get fake goods. I am about to buy 4 new filters from a well know auction site for about £90. They are all Hoya Pro1D 2x67mm and 2x52mm for UV and CPL. If I was to buy them off a retailer here online I would be looking at £250+.
