>>4133570A larger camera is always worse to handle. Worse to move through crowds with. Worse to use anywhere but standing on a deserted street corner taking pictures of a lamp post.
But I guess if you have a very niche application, a DSLR with a prime can be sturdy although you do give up a lot of AF, metering, and video niceties and silent shooting in return for that. God forbid you use the screen to check exposures as that will destroy your battery life (the sony has better dynamic range btw).
