OnLandscape did a pretty comprehensive look at various ten-stoppers recently.

I hadn’t seen that review when I saw this thread and came on here recommend the Haida stuff. I’ve used their polarisers before and a 10 stop screw in and been really impressed by both. £55 gets you a brand new 100x100 10 stopper with gasket. You’d be hard pressed to get a scruffy used big stopper for that. I’d definitely be tempted.
Hey, where do you mean that you can get a 100x100 10 stop for £55? Just had a quick search and can't find much?
This.What ever make you go for buy the size that fits your largest thread and buy step down rings for your other lenses.
As for brands.....have a look at Camdiox/SRB and Haida for 10 stoppers which suit your budget.
This.
but.... pretty sure he needs STEP UP rings not step down rings?
I.e. if he has a lens which is 67mm and a 77mm filter he'd need to step up not step down.
You are correct, it would be step up rings not step down. Was obviously having a mare day that day.
Why do you need a filter holder for an even filter? What is wrong with blue tac? It is what Joe Cornish uses....
