I also did not want to spend a few hundred bucks for a snoot for my YS-01. I ended up building my own fiber optic snoot inspired by the following design:
Fiber snoot for underwater photography
I figure I have about $35 in parts in it plus labor ... and the satisfaction of building it myself.
I did design mine to use the focusing light, but I never ended up using it. I'm also considering shortening the snoot length as they just seemed a bit too long to get them aimed exactly where I wanted them. I used it last week for the first time in Little Cayman and about the only thing I was unhappy with was my method of attachment to the strobe. I used bungee materials which did seem to be not secure enough as the snoot moved on the strobe when I tried to adjust it. I'll have to come up with a better attachment method before the next macro subject trip.
My parts list:
1' 4mm (5/32") Solid Core Fiber Optic Lighting Cable (EGS4B) from Fiber Optic Products - (for the focus light)
1' 7mm Solid Core Fiber Optic End Glow Lighting Cable (EGS7B) from Fiber Optic Products
1ea 1/4" Loc-Line Coolant Hose Kit (#40413) from Amazon (for the focus light)
1ea 1/2" Loc-Line Coolant Hose Kit (#50813) from Amazon
1ea Black Drain Pipe Cap from Home Depot. I took my strobe down and found the size that most closely fit
I drilled a hole for the 1/2" Loc-Line dead center in the cap for the strobe and "threaded" it using a piece of ceiling light threaded pipe which was the same size as the connector. I then screwed in the connector. It was super tight and I never worried about it. I found the correct point for the light and did the same.
You could probably do a pair of fiber lights off the same strobe if you wanted to. As your strobe is round, where mine was rectangular, you might not need to customize the cap as much as I did.
I did find shooting with the snoot to be much more challenging than using just a strobe and it took patience to get something close to the right shot. If you were aimed just a little off, the picture was completely black. You also need a patient subject
I should also point out this made a great underwater pointer.
Here's a picture of my snoot. When we finish going through our pictures from the trip, I'll post some of the snooted photos. I may also try and post some snoot construction photos as well.
