Isn't the whole point about mirror-less the weight and size decrease while maintaining the less changeability?

But once you do use that, and have multiple lenses; the weight difference over the entire kit isn't that much for a decent pentaprism and mirror...

without a mirror you get, no mirror shake

For that you have the option to move mirror separately. At least on my D300. For most shots it's a non-issue

but when the mirror is up, you can't see anything through the viewfinder

it is also a fairly slow process.

you get a viewfinder decoupled from the sensor size or sensor crop -

A very crappy one

the newer ones are pretty good and they will continue to get better

different magnifications

Live view on DSLRs do the same

yes, it is a mirror less camera in live view - as the mirror is locked up

on sensor focus so no mis alignment issues

no what?

on a SLR, the focus sensors are not on the sensor and or in the optical path from the mirror and the optical view finder

the focus sensors must be aligned with the sensor properly or you get cases where the focus sensor says the image is in focus, and it is not,

that is why for focus fine tuning one method is use the live view contract autofocus to set the focus and tune phase detect (off sensor focus sensor) for the lens to match

in theory, since the focus sensors are not interrupted by the mirror, you could better autofocus

Depends on how you see 'better'

better would be faster and more accurate continuous focus since the focus sensors would not be interrupted by the mirror swinging back to expose the sensor

and no mirror blackout

True, but the same could be done with live view

live view is mirrorless

faster fps

That too *could* be done with an SLR.

the mirror will be a limitation on the speed of the SLR

live histogram


the possibility of focus peaking and other augmented parameters - zebras for exposure

exposure simulation

white balance simulation

Isn't that already available with live view on some DSLRs?

yes, when it is mirror less

a simpler camera mechanically -


throw in an electronic global shutter and the camera would be much simpler to manufacture

have essentially unlimited flash sync without some of the issues at high speed with two curtain shutters

probably cheaper and more reliable

But without a real "live" view and therefore always with a lag between what you see and what's happening in front of you.

at high fps and low delay it will be imperceptible - Olympus already has the option for 240 fps refresh on the display
