  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Iso 4000

The mk3 is definitely a nice camera. Great quality at high iso's. The only negative about it I've heard is an autofocus problem when wide open with long lenses.

I want to see an image before getting too giggly tho.

Colin, are you sure that that photo from your link was shot at ISO 3200? I have to admit that I'm impressed at the lack of croma in the grain. It actually looks quite nice.

It's also teeny-tiny in size; when downsampled every image looks better (and in fact, noise is reduced). The native file size of the MKIII images are an order of magnitude larger than that sample, so it's not a good reference to go by.

Here's a shot taken with the MKIII at 6400 iso; certainly "useable" at this resolution: http://www.robgalbraith.com/data/1/rec_imgs/1979_eos-1d_mark_III_vball_06_midres.jpg

(but the un-resized original would look far worse).

Colin's new sample is a much better indication of the image size-wise. Interesting that the picture shows only luma noise - I would be interested to know what kind of post processing may have been done? Here's a shot from the MKIII at ISO3200 from a reputable dSLR testing site:

Note that at 100%, the noise looks much worse than when you shrink it down for the web. There's no question that technology is getting insanely better and what we're able to do today is miraculous compared to digital technology of the past - but I still feel that "useable" is a relative and subjective term and should be taken with caution. A frame grab from one of the ISO4000 tests would definitely be nice.

Keep in mind that if you're shooting 4K with RED but you're delivering to DVD (or even HD, really), you're downrezzing quite a lot and this will help reduce noise. This of course negates the fact that if you are intending to hold on to your "4K master" for projection purposes or high-res distribution in the future, all of the native noise will still be there - but it does provide compelling options for some.

I just hope people don't start shooting everything at fanatic ISOs because they feel the camera is pushable to a ridiculous degree... there are far more numerous reasons to light besides simply illuminating a subject.
 
If I can shoot at ISO4000 / 8000 in low light conditions with no added lighting and reduce it to 720P and it looks great then I will be one happy camper.
 
Great news though late after my bill on the fastest lenses I have got it! :-)

Anyway, go ahead RED team, you are our indie army. ;-)
 
That's is sooooo awesome.....and it's great to finally have an answer on the ASA so I can finally stop humming and haghing about lens ect... Now I can really start to plan out my kit. Great work!
