January 3, 20169 yr Thanks to another thread on this forum I purchased a Tamron 500mm mirror lens and a Fotodiox "Tamron Adaptall to FE adapter." These were all to hang on my α7R. Had an Acra-Swiss plate under my camera and a heavy duty ball head with Acra-Swiss clamp on an old and heavy Gitzo tripod. Initial results were OK, but the lens didn't have enough reach for shy birds. So, I added a Tamron 2× teleconverter. Epic fail – turing the focus ring on the extended lens caused so much visible shake (particularly with focus magnification on) that I literally couldn't focus. On to plan B – to support both the camera and the lens on a rail. Much better. An interim version is shown in the iPhone-6 photo. Am waiting on additional Acra-Swiss parts to make the rig more convenient. Shy birds, I'm after you :-)

January 3, 20169 yr Author Nice setup! Really something. The IBIS is handy for focus, but I see that's an A7R ... Was relatively inexpensive and is great for learning :-) Will one day be an α7R II
