6D + Tamron 150-600 lens.
Just got the lens today, so a quick test, boy it is one big beast of a lens very heavy but certainly not to heavy to hand hold. These were shot HH, through my old glass windows, there are some distortions in the old glass, but im happy with this lens. more testing and eating more shredded wheat me thinks.
It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.
