Hmmm, Still think there should be some way to make it lighter than what is being mentioned, but then I am not an engineer.
To answer David Hall froim another thread tho,,,,, I do not have trouble understanding how my rangefinder works. I just saw a limitation and wondered why not? Isn't that how you get people thinking and coming up with possible solutions? I have been tryhing to think outside of the box.
As for the winding mechanism being in the way, it wouldn't be if you kept the new add on below the top and in front of the camera like a ledge over hang. That is where the existing sensors are. It could be anchored via the hot shoe. But this is just me fantasizing.
Thank ya'll for the input.
