Dear Seniors, anyone know where to buy B+W 72-77 step up ring. I know a lot of shops sell generic ones or kenko's, but I'm looking for B+W to match a B+W CPL filter. Many Thanks

I want to buy a 72-77 mm step ring so that I can use my 77 mm CPL on my 72 mm lens. I'm not sure if the no brand ring will cause my cpl to get stuck etc. So i'm looking for a B+W step up ring. Anyone know where I can find one?

Generic step up ring should work just fine, be it generic or branded ring, it should be fine as long as you do not screw them TOO tight, the ring/filter thread on lens is just to hold the filter, i usually briefly screw in, more than enough to hold the filter in place.

cheers :)

Step up ring just buy no brand one. There's no glass so a no brand one will do fine. Don't need waste money on the step up ring.

Ups for not screwing too tight. Unless u are using the new type nano coated xs-pro cpl, you shouldn't have a problem. Those xs-pro model tends to have very tight polarizing ring. What I do is turning the entire step up ring and try my luck to get the polarizing effect. Not the best way but it does works for me at times.

If you are worry about the threads getting stucked, remove them occassionally. Galvanic corrosion will happen if you have different metallic material in contact especially in the presence of moisture. If you use both B+W CPL and step up ring which are brass, it will unlikely happen.

When screwing in make sure it smooth during the initial few threads. If turning not smooth removed and slowly screw in again to prevent cross thread.

Many Thanks for all the advice. But basically no one knows where to buy a B+W step up ring in Singapore? I have to just get a no-brand one right?

you can ask from the shops that you bought your B+w filters...

well, just did a search and there is really B+W step up ring, but a bit pricey.
Step-Up Rings

BUT, no matter what step up ring you are using, your filter will still get stuck IF you ever screw it in TOO tight, HTH. :)

step up is for a small lens to use a bigger diameter filter, the opposite is true for step down ring.

for you, you should get a step up ring for your 67/72mm lens' filter diameter to use the bigger 77mm filter.

buy a 67-72mm one or 72-77mm one.
