Thanks! I'm using a Sony a7II and Zeiss Makro-Planar T* 100mm f/2 with a Raynox 250 for added magnification.
The Nikon D7100 is a superb APS-C camera body which can be had for ~$750, and the Tokina 100mm f/2.8 AT-X M100 AF Pro D Macro, still one of the very sharpest lenses available, is under $400 these days from B&H and Amazon, lens deal of the century!
Beautiful pics ... I have some Shields also... about the same age... I can't wait to see them grow through your camera, as they are too small for these old eyes to see all that definition... Your pictures are amazing... Keep us updated...
