Cheap diffusion filters - are there any?

Recommended Posts

I'd like to get a round, 82mm diffusion filter, something like Tiffen black promist. Each of those is about £150 / $200 and I'd need more than one. 

Anyone know a cheap alternative? I mean a proper filter I can buy, not smearing vaseline on the lens or similar.

Amazon and ebay don't seem to have anything, but there _are_ cheap versions of other filters, like variable ND and polarizing filters. Are there no cheap diffusion filters because there's little demand?

There are some cheaper consumer diffusion filters but they are too heavy generally, too dreamy-looking. You could make your own net filters for cheap though.

Lee softs are cheaper:

Although looking at the examples they are bit stronger what you might use on glass filters

I've not personally used them on the front of the lens, but have cut them down and put on the back of the lens for a 2/3" multi-cam shoot and they worked  well enough.

Great, thanks David and Phil.

I've ordered a couple of cheap UV filters of the correct size I'm going to try making something out of those and some tights/hosiery, and see if I can get hold of one of the lee filters.

A very tricky way to make a diffusion filter is to lightly mist Acetone on an optical acrylic flat.  It's hard to get the mist just right and even;  you only get one chance!

Very tricky, but with this method, you avoid the potential to get a "starburst" pattern on specular highlights that the weave pattern of hosiery can produce.

Also at the ultra budget end is appling diffusion in post. It can look pretty good and you have more control of the strength and dial it in shot by shot if needed.

OP, you can make diffusion filters very easy with clear coat spray. All you need is a UV or skylight filter and a can of spray.

Here are some examples.

Good luck!
