Ok, so it seems I've "sold" you on the dual-body use, but check out these images of the holster!
Here is one of my K5 cameras in the holster. The lens changer is to the right, and slips into a slot on the holster. The changer is a pretty wide open sleeve to put a lens and change it!
Here, the K5 sits down in the holster without unzipping for extra room. The neat felt pad, protects the LCD, and I can put my straps above the LCD so that it doesn't scratch.
Look at how nice the K5 and grip sits in there!
Nice insides!
Here you can see the expansion zipper in case you need extra room - like if I had my DA*50-135 in there.
A cool holster like this, makes shooting two bodies a breeze!
