So I ran across this product whilst googling today. I've emailed them asking if this system would function with a film camera (Nikon F5) and older flashes (SB-24/25/26). Has anyone here used a system such as this with their film cameras? I know the system it is based off of is E-TTL. It should be able to work with the basic TTL or even matrix TTL off of the F5 right? It would be awesome if this system works. It is a little pricy, but I'll definitely be putting in an order if it does. I'm still waiting on the company to email me back. I'll let you all know what they say.
