Today I broke out a simple shutter speed tester and I have to say, the electronic shutter does one helluva job. I only have the 100mm f/4 at this point but it's looking to be crazy accurate. It's like one pleasant surprise after another with this thing.
While I'm at it, the Tenergy CR123A rechargeables I'm using are doing great. I started testing how long they'd last (room temperature) and I ran out of juice while they still show full charge. Not exactly scientific but one more concern abated.
I did work up a nice 16' 9 volt DC adapter that works a charm as well. I used a 1100mA power supply and it seems adequate. Still needs batteries in the film back to retain it's setting and fire as well. No batteries in the body works fine with the external DC supply.
