basically "Depth of field" increases with f-number. higher f-number means narrower aperture meaning less light go through so slower shutter speed.

lower f-number = wider aperture, more light come in, faster shutter speed can be used, less DOF, more bokeh.

lenses are commonly not at their sharpest when at widest available aperture.

FYI the camera is not as weak as what we think it is. in fact it's tough!

you think about it, which part of the car you put? cushion? in a bag? or you put it in a hard metal case?

it's not uncommon for camera bodies to knock the human body, and other cameras and even walls and tables during events. they can withstand knocks and such.

in car? just put in a bag with some decent padding and you're all set to go. after all you put on the cushion anyway.

you think too much liao la.

no point go so far leh. for me the camera is always in a bag, with padding. sometimes i just put on the seat only, no seat belt. sometimes kena before brake the fella tumble, small matter.

damn difficult to kill any SLR la. at most something not working, can still fix. so that's not exactly KILL isn't it?

you worry too much.

Added on March 13, 2010, 11:49 pmif want to worry, i lagi worry last year cover event and standing near helicopter.

gila my sling bag also become sail already, some more i didn't close my bag. faster fasten it before all my glasses drop out. haha.

this applies to anything la. remember that your camera's LCD are also ......well, LIQUID!

many things around can melt as well since many part of it is plastic.

there are internal components to consider as well. i've placed in car parked in hot sun before but it's in a bag so before the heat reaches the camera internals, it has to heat up the car first, then the air, then through the back, then the air inside the bag.

left it there for few hours, was quite warm when i took it out of the car. i wouldn't do it on a a daily basis though, not for long run.

nowadays i just bring my stuff along. too heavy a risk, unless the place is secure.

mine shooting when heli landing. imaging fighting the wind + handling the bag.

so far i face those heli on a yearly basis la, just that last year i don't recall the heli landing that near. this year if the organizer do the same thing, well heli time again! hopefully by then I'll have my belt units ready.

Not a need, unless you're that careless.
