I know my equipment and I know for a fact if I need the rocks and trees to be sharp, they will be, indeed, sharp.
I knew with out any question how my images would look before I processed and printed them. Old school 8X10/11X14 and much larger film and only needed two shots at the most. Sorry, but I must chortle when I listen to some "professionals" justify their reasons for wasting time.
NOT YOU - TAKE NO OFFENSE!
Every photographer demands something they will never get from the systems they setup and use. I just think there are too many inexperienced photographers out there that have few real skills and they worry about things that a through grounding in the art and science would immediately stop the brain bleeds they often suffer because they just do not understand.
NOT SAYING YOU ARE ONE OF THOSE.
Just a general observation about most photographers--working pro or advanced amateur--that my skill, knowledge and abilities let me say with impunity, the Mini is likely fine if you want a smaller device; the iPad is just fine if you are as blind as Bob.
Again, sorry for the apparent insult. No insult was intended.
