Hey guys, I've been enjoying doing some wide fields recently. Thinking about portability and longer power for my 5DII. One option like I had for the 40D is AC adapter off 240V or an inverter and 12V battery. Wondering about battery grips and how long 2 batteries in ther last for long exposures through the night? Which way would you recommend? BG more portable, but slightly more expensive, not sure how long batteries last, can use for other types of shooting. AC adapter, needs mains or 12V battery, less portable, cheaper, last all night, kind of tethered to the power supply.
