How does the sharpness/focus loo; tough to tell with my ginormous monitor.
Sharpness looks fine, but it always will with the quality of the equipment you're using when you reduce the full image size to something postable here. The basic premise of what we teach about photography here is not so much about simple full-face imaging - you can do that with an iPhone, as Darth so capably proves - but the additional levels of sharp magnification available with the equipment. It's those details, the ability to leverage a big dSLR sensor and capable lens to achieve magnifications not possible with lesser equipment, where the advantage lies.
I always do my focusing at 100% in Live View. This means - even on my 27", 2560x1440 monitor - all I'm looking at to focus is an area about the size of the date on a Morgan.
