this looks pretty good to me, definitely good enough for web. shot full raw, lightroom defaults with upped noise reduction to 48 on luminance and 35 on color. exported with sharpening on screen set to low. there's a resize and 100% crop.

85mm f/1.8 @ ISO 12,800 f/2 1/40s this was in dim dim light. no problems AF'ing either.

thoughts?

VERY usable.

Remember, the screen show much more noise than a print does.

I think your good to an 8x10.

HOWEVER, this one looks to me like a good candidate for a nice B&W conversion.

If you want, send me the file to play with.

EDIT-

Nevermind. Just remembered that I had one of those "affected" Seagate drives and it's still back at i365 getting fixed. I've had to rebuild a hard drive to get me by and haven't taken the time to re-customize my Photoshop with all my actions. UGH...technology SUCKS!

Looks like ISO 1600 from K10D... no joke...

Honestly while "usable" there is significant banding and color noise.

I'd say 12,800 should be reserved for "It's this or nothing" and used for small 5x7 or smaller prints.

yea i noticed the banding. you should see ISO 25,600, it's a banding machine.

aw what the hell, i'll just post it.

after looking at this one, i think the last had a little camera shake going on bc this one looks a bit sharper.

ISO 25,600 f/2 1/80s

ok so tonight i was playing around with total darkness to see what i could come up with on the 5d II, decided to try out live view with the zoom feature for manual focusing...and i realized i had the lens hood on the 30mm. and i took the hood off and sure enough, it took away some of the vignette!!! so the 8x10 crop is pretty much usable. especially in the right conditions where the corners would be dark anyway. i'll still probably replace it, but nice to know i can use it in the meantime.

in case you guys can't tell how dim it really is in here by checking the settings, i've added an exposure close to what everything looks like in here to me.



1. ISO 25,600 f/1.4 1/40s with lens hood attached

2. ISO 12,800 f/2.8 1/80s with hood

3. ISO 12,800 f/1.4 1/20s without lens hood attached

really no point to this post other than more samples.

Webpage? Absolutely. Small prints (6x4")? Maybe.

Pretty amazing to be able to shoot anything at these ISO's. You should print the first two 4X6 and 8X10 just to see how it looks; I'd be curious.

Is that your wife? I've seen that facial expression before...

Usually it's followed by me disliking the high quality build of L lenses especially in terms of when they impact my head and my head takes the greater damage....

:p

It's impressive for what it is. I think the bigger "thing" is ISO 6400 being perfectly usable. That basically takes every F4 lense and makes it usable at what F2.8 lens SS would be by giving you 1 more truly usable ISO boost.

nope, it's my girlfriend. the first guy is my roommate. both of them are pretty patient with my sudden "hang on, i'ma take a picture" moments. it's not my fault though, i see conditions i'd like to test and i have to test them...right then. in the first set we were just about to walk out to door to go work out. in the second, we were sitting there about to head to ihop! my shoe also makes an appearance. and buddy's the white fluffy dog, he's my dog...bill's the other white/black dog, he's my step dog...got him in a breakup.

shawn's actually in the april issue of muscle and fitness magazine that just came out this week....if anyone here subscribes to it. he's the guy in the gritty black and white set.

Ah men.

If ISO-3200 matches the Canon 20/30D ISO-800 and the new ISO 6400 is even marginally presentable without obvious degradation (ie: the lay person won't really notice) then this is revolutionary and worth the upgrade expense.

i'm gonna have to agree. it's a freakin bargain compared to the 1ds
