5D Mark III & More Information [CR1]

[LetTheRightLensIn]

I just hope that they don't hold back all the FF speed to big bulky 1 series size monstrosities and allow for EOS 3-like gripless usage for the times when you really don't want to have to deal with all of that (and i'd be willing trade lime 10fps for 7fps, lesser weather sealing, not quite 100% VF and such for a little bit of cost savings).

Serious question.

Of what practical purpose are these very high ISOs?  Who used them and for what purpose?

Serious answer: to take pictures of Yuletide re-enactors in a room lit by three candles, located in a 19th century historical village or to take pictures of musicians in a very dim jazz club. In both cases, the exposure was 1/15 sec, f/1.4, ISO3200. I want 4 stops improvement, to ISO 51,200, 2 stops to get the shutter speed to 1/60 sec and 2 stops to allow me to use f/2.8 zooms.

Another serious answer:
Taking photos of a party at my salsa school, darkened room with a few coloured spots on a mirrorball, mostly full-body portraits if i could get the room

Just a selection of EXIFs from that night:
7D, EF-50 f/1.8 @ f/1.8, ISO5000, 1/50s, -2/3EV for Sassy doing a speech on stage with lights on him.
ISO 5000, 1/13s, -2/3EV for dancers with the lights on.
ISO5000, 1/100s, -8/3EV with the lights off and just the mirrorball.
or ISO3200, 1/50s, -1EV with a bit more lighting.

all in Av mode, lighting changing too rapidly for M, -EV exposure comp was to try to keep the noise down and not blow out the lights (didn't help most people were wearing black), couldn't use a flash (a: don't have one, b: can't piss off the dancers). too much motion blur in most of them, the others too dark, the rest too noisy even RAW-processed and shrunk to 1/4 original dimensions. sometimes even f/1.8 was not enough DOF to keep the entire subject in focus, so going f/1.4 or f/1.2 was out of the question, especially as they were dancing back and forward unpredictably.

yes, 7D and 50/1.8, best i had at the time (i even bought the 50/1.8 for shits and giggles just to try it for this event).
(yes, I would have taken a 5D2, or a 50/1.2, but i don't have them).
If i could have used even ISO16,000 with the same noise as a 7D's ISO3200 i would have loved the faster shutter, more DOF, and 0EV.

If you ever get a flash for your 7D you could try a soft bounce with gel (so inconspicuous nobody will even notice ) and rear curtain syn to enhance the motion of the dancers. A good flash really compliments the 7D's higher ISOs.
