So I’ve got a 70D the other day …. to upgrade / replace my 60D so to say.
Things change a bit on that cam. There is no movie mode on the mode-dial anymore its more like with the 7D … There is a movie/live view/photo switch on the right.
Anyway, I noticed that I can set / change the ISO range in the menu and even in Video mode I could set it to 12800 for maximum ISO.
But how good is it? … Is it useable? Well, i did some random test shots at a local Christmas market.
In the end it is by far no C300 or C100 by far and there is quite noticeable noise at ISO 3200 and more. But like others said before the noise is not as “awful” as with the 60D or 7D.
But then again, it’s no C300 organic looking noise. Depending on what you shoot and if there is enough light in the shot and especially with a wide open prime lens (like with in some shot in this case a 85mm at f2.0 or 2.8) you actually might be able to use some of the High ISO shots at 8000 or even 10.000, not every time tho’ and there will be some quite noticeable noise but I’ve seen worse.
At 12.800 it’s almost not really usable but you could get a shot you otherwise would miss. Almost all detail is gone tho’.
But again, I’ve seen worse or in the case of a 60D you would not be able to even think about those high settings at all. But see for yourself.
I did some quick basic “color grading” in Magic Bullet Looks and some basic noise reduction with DenoiserII…
You might be even able to “recover” / use more shots if you spend more time on Post so to say.
One more thing: In low light and with high ISO settings the Autofocus has a hard time since there is not much details left in the shot and the auto focus does not find a point to focus on it seems …most of the time.
One last thing: The 70D has a built-in stereo microphone on top or the viewfinder, it works nicely but it is picking up camera- and “user-noises” quite easily at times.
Over all it still is “only” a DSLR with Video mode but with nice autofocus options and a bit better ISO range.
