One thing that I am resoundingly unimpressed by is the USB connection for power.
Its nothing about the unit itself...I just hate that flimsy connector...
I never use the USB for transfer - only power.
So - mod wish...some other connector!
I'm fine with losing USB transfer in favor of more robust power connection...since we'll almost always be running this deck off externals.
I know this will mean a custom cable...but I'm ok with that too.
Never thought the microUSB was any flimsier than that same connection on my cell phones or any other things that use it. I highly recommend a right-angle cable if you're not using one already - doesn't stick out much and feels much more secure. I have copied the same battery and cable setup recommended by Groovon
here, and it's completely solid for me. The cable stays plugged in except when doing transfers, for which I use the longer cable that came with the 70D. He actually found
this other cable since then which only requires one bend rather than two. I have stuck with the first one.
If you're not sticking the battery right underneath the unit and instead have it somewhere else in your bag, you'll want a right-angle microUSB that goes the other way. When I did that, I used
this cable that sticks out and then reaches to another compartment in the bag where the battery lives.
I'm sure some enterprising person could grant your wish and drill a hole to put a hirose connector on this thing, but it seems like way overkill, and the cable will cost as much or more than the battery.
