take out the built in flash gun and have a bigger 1:1 prism - that will do the trick. ISO high also no need much flash. Maybe i should work for nikon...hehe
Agreed, the pop up flash is a weak point in construction and takes up space. The only usage people find good is the CLS commander, but at this kind of level usually people going for radio triggers or another speedlight on-cam as commander with 3 groups.
Dual card slots would be nice.
