Here's a little something you may not know about the SG flip... it originates from the original Letus flip design. Almost bolt for bolt! Shoot35 used to sell the Letus flip and give the fine boys at Letus credit for it. However a while back they started machining it themselves using Hien's designs and therefore there shouldn't be any difference between the Letus and the SG flip modules.

However, you may have problems getting your hands on an SG! I heard rumors of them discontinuing the device to make room for their new beast about to be released!

Nice.
I do love my LEX, but not being able to stop the lens down at times, and the slow shutterspeed barrier is starting to do my head in.
In saying that, having an external monitor flipped then flipping in post is just a set of problems that I just can't be bothered with.
