Do Firecrest ND's scratch super easily?

[Mike Kozlenko]

I'm in the market for ND's and I've been told by a couple people that Firecrest ND's are pretty fragile & scratch easily. Just wondering if anyone has had this experience with these ND's? I couldn't find anything online about their supposed fragility but I just wanted to double check on here since 2 different people mentioned this issue to me.

Nah they're pretty robust.

The Tru NDs are the ones that you need to be careful with.

The Formatt Firecrest ND's have their ND filter contained in-between two sheets of glass. Using them, I haven't noticed the glass scratching super easily, but maybe they do compared to other kinds of scratch-proof glass (that doesn't get used for high optical quality ND filters).

Here's a good list from Phil Holland regarding ND filters - http://phfx.com/tools/redThing_REDDSMC2_NDFilterNotes/phfx_REDDSMC2_NDFilterNotes.jpg

They've been very durable for me.

I had a very hard drop on the corner of one of mine and it barely cracked a 1/10th of an inch in. Still use it. They’ve been really durable.

Just make sure and get the ones that are 4mm thick. There are some that thinner and are not sandwiched between 2 sheets of glass. For example the 4x4 filters vs the 100mm x 100mm. Or some screw in filters. There is a thread on Reduser talking about it here.
