Any disadvantage of using step-up rings?

Hi,

I'm current building my photography toolkit and am focusing on screw-in filters. I currently have two Nikon lenses, both with a 55mm thread. However, I am planning to buy a wide-angle zoom (prob. Sigma 10-20mm) which has a 77mm thread. I was thinking about using step-up rings so that I just have to buy 77mm filters and they can still be used with the 55mm lenses.

Would there be any disadvantage to taking this approach?

TIA,

Iain :)
 
Only that you may need to also buy a 77mm lens hood.

Not sure you can go from 55mm - 77mm in one step so it may cost you more than you think.
 
I found a step-up set from 49-52-55-58-62-67-72-77-82 mm set on eBay for £12. Didn't think about the lens hood...very good point.
 
You may see some vignetting with certain combinations of wide focal lengths and wider apertures, even with the step up rings.

Out of curiosity, what lenses do you have with a 55mm filter?
 
Good spot - it was a mistake....they are actually 52mm Nikon lenses (18-55, 55-200) :) Sorry about that.

Thanks for the tip. Is the vignetting problem just when using a big step-up (eg, 52-77) or even with small steps?

52-62 and 62-77

Get a centre-pinch 77mm lens cap, too.
