I wasn't saying that here, but essentially yes. If there is 2 stops less (i.e., 1/4 as much) light the amplification needs to make the signal 4 times as high, which makes the noise 4 times as high...

Miki, let's just make it simple and say "2 stops more noise". :)

Miki, its noise level is 4 times (=2 stops) behind FF.

I see no improvement at all. It's still 2 stops behind FF sensors, just as all previous sensors 1/4 the size of FF.

Jon Stern, the sensor only has 3 color sensels. Unfortunately there's no way to do as you hope, and the problems with Isolite's solution has exactly the problems that you highlight exactly as you...

You can do the same by using red, green and blue filters, then using your normal RAW processor's channel mixer for the b/w-conversion.

...except that the equivalent MFT systems are not smaller, and in many cases don't even exist. OTOH, MFT has many lenses for which there are no equivalent FF counterparts either.

CCD, I stand corrected regarding the size of the sensor. However, the high base ISO is still a significant problem with current MFT sensors, yanking that 2/3 stop difference up to a 1 2/3 stop...

DC, nice! But weird, because in TCSTV's preview they checked the camera *and* asked the Panasonic rep, and both confirmed that it's not a "world" camera.

Does it have 50p and 60p? Usually Panasonic likes to just annoy people by needlessly restricting their cameras by removing either PAL or NTSC framerates, depnding on where you buy the camera (as if...

MFT -> APS-C is just as big as APS-C -> FF. Particularly taking into account that the base ISO of this is 200. That means it's comparable to an APS-C at base ISO 400 or a FF at base ISO 800. So if...

The problem with sony is that there just is no reasonably sized superzoom. I would love to have a small f/7 (i.e., f/3.5 mft equivalent) superzoom on it, which I could use when traveling.

Don't forget the 10 minute video recording limit :D

As someone already mentioned, when making equivalent lenses for smaller sensors they end up being equally big. However, I wish manufacturers would also make equivalent lenses for larger sensors....

@jrutsch Yes, people do. Very often. They go, "I have a sensor that's 8 times smaller, so I better dial down the ISO to 1/8th". When I shoot FF I might happily use ISO 800, but then when I use mFT...

It's very much about understanding how it all fits together, so that you can make better choices which products to buy/use in which situations, instead of having to trial-and-error everything.

Let me quote the article which you, LingoDingo, clearly did not read/understand:
"You do not need to consider equivalence for a moment when choosing an exposure. You do not have to multiply the...

The equivalence IS about understanding light!

DoF is the primary thing the F-number signifies. For exposure you use T-number.
Also, the equivalence is not only about normalizing the DoF, but also the image noise (read: image quality).

Is there any speedlight system which has a "flash ready" beep/light on the transmitter ? Usually the speedlights themselves beep, but instead of listening to a bunch of beeps from all over the ...
