I'm perplexed. Isn't the Dragon suppose to be ultra clean at 2000 iso? I'm with Patrick on this one. 250 iso is really a step backwards in camera evolution. I've had a chance to shoot on the Sony F5, it's amazing at 2000 iso. I've ben shooting with the Digital Bolex which can't go above 400, but you can then push it is post and it is CLEAN. Why on earth would we set the dragon at 250 iso? I've been shooting the MX mostly at 800 but sometimes yes I'll take it down to 400. What's happeing here, is the Dragon really creating a lot of noise that we need to take it down to 250? I had also read that the Dragon had really very little noise even when shooting at more than 8:1, what's up?
Cheers,

until now I was shooting broadcast ..... got my scarlet dragon ..... first test ..... grmpf ..... straight out of the camera ..... never had issus with focus - now I have ....
my mbp without retina makes me nervous about the pictures ..... :mad2:
Have to get new monitors .... obviously ........... ;-)

No body has ever said 2000iso was ultra clean on the Dragon... however I do get results (when exposed correctly) similar to 800iso on the MX.
Not sure what a lot of people are doing when wanting to shoot at higher ISO's. Many are cranking up the ISO to 2000, 3200, 4000 and expecting a miracle perhaps, You need to remember that when your at 800iso and the image is dark and you feel you need more light, soooo you open up to 1600 or 3200iso to make your monitor brighter... But your histogram is at the bottom end (left)... meaning your still grossly underexposed.
Your now underexposed. If upped your ISO, but you haven't put in anymore light or opened your aperture to get that histogram back into the right side of the histogram.... Your just expecting that the camera save you, but the fact is your not exposing correctly in the first place is what's really happening.
So do a test, set your camera to 2000 or 4000 iso, light your scene or set your aperture of your lens allowing the histogram to be on the right side (brighter side) of the graph. Then see what noise you get.
I can totally live with the noise I'm receiving from the Dragons and MX Cameras.
but my point is just to exemplify that one camera can never truly rule them all, best tool for the situation is always the best tool, whether you own it or not
Going from 2/3 inche Broadcast camera with huge depth of field to a super 35mm sensor with a 1/4 of that depth, you'll need to learn to use your focus assist tools.![]()
Great shots, Mark. Are these with old OLPF, new OLPF or both? The reason I am asking is because I see some shots from your first dragon tests, which I believe were done with the old olpf.
cheers
My reason for the last post is try explain to people (that are having noise issues) is to keep that histogram to the right near traffic lights even in Hi ISO's. Then your exposure is correct.
If its to the left, then its not. Simple as that.
If I understood Mark P at Reducation correctly, the ISO figure is meaningless when it comes to what the camera is actually capturing or is able to capture. ISO seems pointless.
Nobody says it's 320 ISO (except the original red one). Red actually rates it at 800iso which is where they say (correctly) you get the most even number of stops over and under middle gray.
like film, you can rate the sensor differently than the manufacturers suggestion. You can also rate other digital cameras lower.
I've always rated the MX and dragon at 320. With MX you had to watch highlights way more than you do on dragon and blown highlights in dragon actually roll off smoothly (not the hard clipping of MX)
rating is based on how clean an image you want to get and noise tolerance. But how much light you let hit the sensor is the biggest factor when it comes to noise. This is also the biggest factor when you push process (raise the ISO in redcine x)
I also rate lower on exteriors because I am not into shoving too much ND (glass in front of my glass) because the higher ND needed when rating at higher ISO's means I can introduce IR problems and need to cut more light to the sensor. This is less of a problem on Dragon as I only start to notice color shifts at 1.8 ND and above. The IR filter built into the dragon OLPF is excellent.
common problem we see a lot here on reduser. Histograms don't lie.
Camera is set to 800iso
lens is 2.8
metered light is 1.4 or less
shot is captured 2 stops under
shot is then processed at 2000iso
see how this can create noise?
if this person rates at 320 they they will look at the scene and say, "this is dark, we need more light" if they added even a stop or 1.5 stops of actual light (not boosting the image by raising ISO) then I think there would be a lot less complaining.
Two stops under is going to get you noisy images on any imaging system that does not have auto enhancements to make up for your deficiencies (like an iPhone)

RAW view on MX is 320, that's what I was basing it on.
After reading tons of post about noise issue, and i am really tired of reading about them, let see if i can explain something about the v2 dragon. Basically it is the same sensor as the original dragon. What has been updated, or better yet, improved, is the OLPF. The new one gives you many improvements over v1 olpf. But like many things, sometimes to improve some qualities you have to trade with other things. What I am talking about is olpf sensitivity. The new one eats more light, about 1.5 to 2 stops maybe. So the light hitting the sensor is a lot less. So if we rate at 800, in reality the light hitting the sensor is the same as if you were rating somewhere @2000 or more. This of course means that the image will have more "sea monkeys" naturally like any system without NR.
In other words what was 800 before now is 320-500iso . I personally think it is a great trade off considering all the benefits v2 olpf gives you.
If i am wrong please enlight me.
Not shooting in the dark and then trying to suck out light afterwards. Which is the major problem for novice players.
