Fotasy 49mm Metal Filter Stack Caps, Filter Stack 49mm, Aluminum Alloy, Slim Stack fits 49mm UV CPL Fader ND Filter

Headline sums it up pretty nicely I think.There are some things to keep in mind though. If you switch out filters a lot then there will be a lot of screwing and unscrewing to get to the one you want. That isn't me, so I'm good.The second set I ordered sticks a bit, which led me to discover my filter frame had a dent. That's not this product's fault obviously, but if you have old filters that might not have the best threads then keep that in mind.Finally an additional tip, I may end up not using both sides of this product. I have an extra lens cap so for the cost of a few mm thicker stack of filters I can shave off a few seconds when needed.

I've been trying to organize all my gear because I can never find what I'm looking for. I searched and searched for filter holders, but they're all sized for the biggest filters (dumb, when you're trying to protect 52 or 58mm filters), don't have enough pockets, and are insanely expensive. I stumbled across these and just felt stupid for not thinking to search for them in the first place. They're perfect: all my filters are grouped by size, they're all in one place, they're neatly (and satisfyingly) protected without taking up a ridiculous amount of room, and I have money left over for new ones.The only downside to stacking them is that the thicker magnifying filters can't connect to each other, but that's not the fault of these stack caps. And using magnifying filters isn't something I should admit to anyway... but they are pretty handy :) Anyway, I stuck those in one of the filter holders I already had (with not enough pockets for ALL my filters), and everything's perfectly organized now. I'm very happy with these!

These are great pieces—especially for the price. I use them for my Meike prime lenses (the lenses come with cheesy squeeze-release caps that are always falling off). These screw on’s are solid and perfectly machined and just feel solid in the hand. I’m looking around to find a local company to laser etch the millimeter measurements on each cap (8,12,25,35,55,85) and then all will be right with the world!

High quality product. Very satisfied.

Love the build, these caps are heavy and sturdy. Really good fit with my Tiffen filters. Only thing I want to mention, especially for people with OCD like me, is that the black paint will go, especially where the filter thread is. It will not impact the functionality but it will attract scratches. In this case for me, it doesn't really matter. I just wanted a compact way to carry my filters in my bag. Great buy.

These have been the best way I've found to store and transports my assorted sizes of CPL filters. Keeps the clean and dust free and offers the best protection. Just be careful to not overtighten the caps onto your filter, or camera for that matter.

...lens caps. My experience is after awhile the threads get messed up and eventually don't stay on very well. It's worth the extra effort to have something more secure and better overall protection. I like that these have a slight satin finish to them, they look more professional than the plastic ones. As far as putting them on, I always lightly place them on the filters and gently screw them backwards until the threads match each other then gently screw them on to tighten. I have found less chance of stripping the threads this way. Good quality caps should last a long time.

This filter stack cap is the best way for me to store, protect and carry filters. This one was for a few 82mm filters including a CP. Filters screwed into case easily.

Excellent way to cut down the space required to carry multiple filters. I love the metal construction, they are rwally robust.
