Hey guys, been researching getting the GH4 for some time now and a deal on Craigslist has popped up and I'd like your opinion on it!

It comes with the GH4, purchased in April, metabones speedbooster for Canon EF .64x, 5 batteries, and a 256gb SD card. Also comes with Canon 50mm 1.8, and a vivitar 85mm 1.8.

This all costs $1,500. Is it a good deal? What should I look for when purchasing? I already have a Nikon 35mm 1.8 lense which I had been looking forward to using if I went with a Nikon Speedbooster but does this deal worth passing up? We will be shooting real estate videography

Thanks in advance
