Hi @Kings
I use the Freewell ones at times on my MP2. Usually the 8-0 or 16-4. Rarely the 32-8 but I miss the polarisation element which I use a lot. If you can get graduated & polarised ones they’d be perfect for landscapes lol.
@GreyDad here’s the ND filter equivalents for the freewell gradient filters.

Arrived today, will hopefully get out later and get some comparison pics as reference for others if interested.
Looking good! Damn you beat me to it. Ordered mine today 
Now ordered, should be here tomorrow.
Along with a few other bits and pieces I couldn’t resist

Schott glass is best. Freewell filters are quite well known for being good quality. Like most things, if you want quality, expect to hear your wallet groan. Avoid the cheapo knock-offs like the plague. The company I mentioned seem to do the widest range. It won’t matter if you do decrease shutter speed, you will always get noise in the shadows because of the relatively small sensor size. The best tool I’ve found for dealing with this without excessive loss of sharpness is astrophoto Denoise module in the DARKTABLE editor.
Has anyone tried K & F ND filters?
They don’t seem to do gradient ND filters - the subject of the thread?
I have a few K&F products - really well made.
Sorry, will pay more attention next time.
