albnok: so its not like QLV where is has a limit of minimum light to able to see? i am afraid of this only, our eye can see real dark alley with minimum light sources... i wonder what the sensor can read...

d4rkholeang3l: the calculation of TTL is very sophisticated. u dont have to worry a thing, because IMHO, its very accurate. preflash is a consistence power fired, it will not fire more powerful preflash when it detect low light.

let me give u a more simple layman explanation.

let say for EXAMPLE, that preflash is 1/16 to ease the explanation.

when u use 1/16 power to fire direct, u get 100% of 1/16 on subject. hence the flash will fire only 1/16 power to lit up the subject.

when u bounce 1/16 power, u get lost of 40%(example) power in bounce, hence u only get about 1/32(example) light on subject, what TTL does is, it increase the power from 1/16 to 1/8(example) to give back the light on subject.

now, when u use a modifier (stofen or anything that diffuse the light by having something semi translucent, it take away more power then u think, up to 80%! (example)) hence with 1/16 power fire and left with 20% reaching the subject, the TTL detects it, and calculate it, fires 1/2 to compensate it.

the modifier will not affect TTL calculation much, but a modifier does affect how much the power is used.

so simple to say, comparing normally 1/16 power to 1/2, that is 3 times more power required, hence average of 600 shots(example), are down to 200 average shots

*let me stress it again before someone quote me per quote. the pre flash do not fires at 1/16, it was solely used as an example to ease the explanation.

jedi_master: thank for a nice review!

the EVF is great i heard from many friend who tested it, but i would like to see it myself. but from my own understanding.... the EVF has higher resolution then the Nex/A33/55 LCD display! so if u cant even see pixels on the LCD< the EVF is far more sharper (unlike pass EVF with pixelatted effect).

the iso test, cannot be used. because the iso6400 gain, increase the shutter speed drastically, under florescent lighting (they are green pulses lighting) u might capture the picture in the middle of a pulse at high speed, hence causing weird green tint and the WB somehow balance it back with yellow+magenta tint. the iso6400 and 12800 is not accountable for 64/128 iso test result.
