One of the things I dislike about the Pixapro EF-Mount Optical snoot is that the gobo holder and the gobos are a non standard size. This means having to purchase the ones produced by the company. It is very limiting and not many of their gobos appeal to me.
The gobos are sold in sets of four by Pixapro and if the ones you want are in different packs it is tough luck. You will need to splash the cash on the gobos that you might not want and will never use.
So it was good to find a company like GoboPlus that can provide a holder for use with M size gobos.
M size gobos do work with the holder that comes with the optical snoot but you have to tape them in. So having this new holder means that I can now use any M size gobo without any fuss.
