Thanks Guys
Rene: I use Contax Extension Tube 13mm on this shot for Contax 28mm f2 Hollywood
It's almost too much for this 28mm .. would like to have Contax Tube 7,5mm
My wife told me that northern light could be seen so I just grab the camera and tripod and went out. It wasn't the best show, but anyway here is one from this evening. Sony A7, Canon FDn f2.8 @2.8
Late day sun on Caddo Lake in Texas. A7R with 100-400L (exif shows Tamron 18-270, which I know is not correct...must be a glitch with the Commlite adapter).
