Taken on my GH4 with a Canon FD 100mm f/2 and an RJ focal reducer, making it a 72mm f/1.4 shot wide open.The lighting isn't particularly great, with the subject standing in a shadow rather than the sunlight, but it was a spur of the moment photo. I'm pleased with the DoF and sharpness I'm able to get out of this combo wide open, and it only gets sharper when I stop it down to f/2.
