Photography: Camera sensor size difference

hmmm... i got pin sharp images manually focusing with me 100/2.8 macro near the minimum focus distance (i.e. near 1;1 reproduction) at about f/5.6 on an eos 5 (film camera.... remember them?) before i had to sell it, and that was on a breezy day, handheld, with the flowers that i was shooting actually moving about every so often... pics have been blown up to 18 x 12 inch and yep, dead sharp (obviously not the entire image but the bits that were within the depth of field range)
thats not saying im good at photographing stuff, thats saying that if it can be done by a complete amateur fucktard like me with complete ease, then wtf does anyone need live view for.

but you didn't know they were sharp until the film came back.
if you are at a location or hire studio with props or models (which all costs money) and the client looking over your shoulder do you think you would just chance it, trust the cameras af or use live view to ensure critical focus? it's easy to use and means no fuck-ups, this is a good thing as it puts food on the table and makes your life easier.

Fuck live view, tethered shooting and lightroom 2 ftw.

tethered is great but often if i want to be a bit more mobile or shoot in a public place, without an assistant to carry the laptop or in shitty weather then live-view and the big screen on the back of the camera is incredibly useful.

er, you use a zoom on a p45?

yes it has been known.
