Are you sure the additional 30 seconds is not due to high ISO long exposure noise reduction? As per my understanding from my previous Canon 550D, if high ISO long exposure noise reduction is on, the camera will take 2 exposures of equal duration: one normal and one with the shutter closed. The 2nd exposure will be subtracted from the first to reduce black noise. Just tested with my NEX-3 and it is the same.


BTW does anyone know if NEX high ISO long exposure NR can be turned on/off at will? Or can it only be set by the camera depending on the shoot mode?

what puppydogpoo said is correct... if you dont want the extra 30 seconds, turn off your long exp NR..

is it good if we turn off the noise reduction (NR)?
or at what time we should use NR what time we should disable it?

in most cases, i keep it turned ON..

times when i turn it OFF is when im shooting fireworks or when i need to keep shooting without delay in between shots

which NR u turn off eh?

if not mistaken got 2 types. long exposures nr and smthg2 iso nr? forgot. on bed edy. pretty lazy to get up n chk.

what is the diff between both?

mine is off ever since i found out that the additional processing time is not worth since noise level during long exposure are quite low

the other one is High ISO NR, it can be either auto or weak but can't be off (mine is set to weak to preserve details)

For long exposure noise reduction, the most important part of it is to eliminate hot pixels. I leave it on all the time. Even during fireworks.

hey thx evilhomura89.
me still got no chances to play around with my cam. still havent get use with it.

nite everyone.

jom! but my nex battery can last less than 4 hours only

aiyo brader...you're taking slow shutter...sure la slow process...you have NR/High ISO option on...if you take 1 minute shot and the process takes a second,gila power your camera...dont jump to conclusion la brader....haiya...do abit of homework la sayang not just saying the card is shit or what not...

Codyx: If you turn off SteadyShot, it will last as long as any other dSLR shooting video.

puppydogpoo: Yes, you can turn off Long Exposure NR on the NEX bodies. I tried in A mode. However in iAuto, the option is On and cannot be disabled.

fansoption: Nicely done in #3!

Strange... On my NEX3 with Firmware 3:

M and A mode: Long Exposure NR Off. Cannot change ("This function is currently disabled")
Night View Scene mode: Long Exposure NR On. Cannot change ("This function is currently disabled")

I didn't test iAuto bcos AFAIK it is supposed to detect the scene and apply suitable settings, so will probably get inconsistent results.

Image type was Fine JPEG and High ISO NR was Weak.

how i know? i see those canon fellas next to me.. take 30 sec shot, no need to process at all. straight away review shot. i ask them what sd card they using, they tell me sandisk class 10.

coz the canon fellas next to u did not have NR enabled... (or could be dont even have NR *larikkkkk*)
