first basketball with my MIV

I shot my first basketball game with the MIV on Saturday. I used two lenses, the 85mm 1.8 & the 70-200mm 2.8 IS. I registered a custom white balance underneath one of the baskets, then, like a goof, I left the setting on AWB. This was just a warm up game, so not really a big deal, but I'm frustrated that I did that. Lighting was terrible in this gym with a mix of some metal halides and some old mercury vapor luminaires. Anyway, I was very impressed with noise right out of the camera, but I'd be interested in opinions. Of course, C&C is always encouraged.

#1: 85mm f2, 1/500, ISO 2000

#2 has too much noise...at ISO 4k with the Mark IV you should be able to see zero to just a tad of noise. Did you shoot RAW? I assume since you are setting a custom light balance that you are shooting jpg. But even in jpg, there should be less noise at that ISO. You might want to play around with it some more.

I thought that #2 had too much noise as well for ISO 4000, but I was shooting RAW. I don't understand your comment on the custom white balance & jpg. I always set custom white balance & always shoot raw. Can you help me understand your comment a little better? Thanks for the comments.

This one below seems to have much less noise level. I'm wondering if the other picture was just noisy because of exposure and maybe it's not quite in focus?

#3: 70-200mm, 100mm, f2.8, 1/640, ISO 4000

If it's not exposed correctly, more noise will show up, the higher ISO you are at. That's probably what happened because it's definitely overexposed.

Perhaps the comments refers to the fact that a custom WB isn't really needed when shooting raw since you can always define WB afterward. Of course you'd need to have shot a grey card to get it perfect.

Davis is spot on. I shoot 90% of the time RAW and fine tune the WB in post on my first image in LR (along with a few other adjustments) then sync all the images with it. Remember when adjusting WB in the camera all it is doing is taking the RAW file and adjusting it. The RAW file is not recorded differently. It's just the RAW data. Best thing to do is take a shot of a gray card (or a white piece of paper) after you get your settings and use that in post to correct the rest.

Maybe...but the back ground had grain as well. As elrey2375 stated it does appear to be over exposed...but when shooting high ISO it's better to shoot to the right and then bring down the exposure in post, as that will help hide the grain. The skin tone looks off as well. If it is only due to be over exposed you can save the image. If it's OOF might as well delete it.

OK, that makes sense. I usually try to set custom white balance prior to the shoot, but the more I read, the more it seems that the method you listed above is easier & more consistent.
