Originally posted by Al_in_the_Shire I've had the Photosolve Xtend-a-Sight mount for a couple of years and it works well. I have yet to have to readjust the sight after removing and remounting it in the hotshoe (I keep the sight on the mount all the time). I've also seen Red Dot sight mounted on the hood of a lens. I'm thinking of trying a Daisy sight wire tied to the side of the hood of my FA*300/4.5. I think I might be able to use it with my left eye while my right eye is looking through the VF.
Attached is a shot of my Tasco RD sight on the Photosolve mount on my K20 w/FA*300/2.8. I don't use this set up for BIF, it's for quickly locating small birds in foliage.
