I have the 1D3 and 5D2, and the 1D3 is better than the 5D2 at the pixel level, but the 5D2 has a very slight edge when the 5D2 is downsized to 10MP. The 5D2 would have a marginal advantage over the 1Ds2 (at most 1/3 stops) right through to ISO 1600

You did these comparisons backwards. Up-size to the higher resolution and then compare.

Nope...you get it backward.

Just considering what you would get if you took the same shot on a 1dm3 and 1dsm2 and enlarged them to 16x20 or 20x24 straight from the raw so to speak. (well, processed, converted to max quality jpg)

Which do you think would be better??

They'd be pretty similar I reckon

I used my 1D3 and 5D2 at a wedding last night for the first time. My lenses are all EF lenses (14,35,85,70-200) and the FOV is much better on the 5D2, but I preferred just using the 1D3, the focus and usability is far better

Especially during the low light dancing section of the reception, the 5D2's AF was a joke compared to the 1D3. The 1D3 + 85L II is almost instant lock (even though the 85LII is a notoriously slow AF lens).

The disadvantage is with the 1.3X crop which made me a bit too long frequently throughout the night...now to save up for a 1Ds3 or 1Ds4

I did more IQ tests, the 5D2 has the edge past ISO 1600 especially when equalised for resolution, but they are pretty much the same up to ISO 1600. The 1D3 low ISO files (100, 200) are far cleaner than the 5D2

Sorry. We have been through this over and over. You need to upsize to compare. Hopefully Brainiac will drop in here and go over the details. Otherwise search for his post.

I'm as fanatical a pixel peeper as anyone, but to be honest I think the 1D3 and 5D2 are all but identical at the pixel level..which imo is the most important, because the only time when noise becomes relevant is when I want to crop heavily (since both cameras are otherwise very clean at full resolution view). And when I want to crop heavily, it's noise at the pixel level that matters, not an upsized image from 10MP to 21MP (why on earth would I want to do that?)

So I guess I'm happy to accept your view that upsizing is valid, whereas downsizing is not in terms of for testing validity. But I guess to me personally it's not important

But I can appreciate the need to ensure testing validity before robust comments can be made about relative performance

I will let you know later today for sure, but the 1DMK3 I am testing has so far not achieved the image quality that the 5DMK2 does. Unfortunately this does include noise. That is not to say that the 1DMK3 is not a great camera. AF, shutter lag, and blackout are much better. I also think the 1DMK3s default color settings are more true. The 5 series always seems to have too much red.

If you lean towards action then the 1DIII, if towards portraits 1DsII. YMMV

Thank you all again! So correct me if I'm wrong. But for most things the conseus seems to be that 1dm3 is the thing to get.

I mostly only shoot low ISO, a rare 1600 when shooting the fights.

Am I correct in thinking that the 1dm3 is superior to the 1dsm2 in these areas?

Thanks folks, all your user insight is very helpful to me, and I hope others.

^^^ what are "these areas"? Actually, I think your posts gave the impression you do a lot of low-light work, hence the recommendations for the 1DMKIII. If you're shooting mainly low ISO, I think the 1DsMKII would be the better choice.

In these fight events is frame rate an issue? If so, a 1DMK3 is probably a better choice.

Sorry. The areas I referred to were low ISO, Glamour/Erotic stuff. But I do shoot weekends at clubs where the light is low. I do use a Quantum strobe, but still shoot around ISO 800 and slow shutter to pick up ambient club lights. Low light focusing is an issue.

And in the glamour work, using some of the 5d non center focus points can sometimes be a bit iffy with 2.8 glass (not often, just on occasion if the light is a bit low)

Does that help at all? Really appreciate your insights.

Frame rate really isn't. I can certainly appreciate it that it could be. But these fights are only once every couple of months. All other shooting is always single frame.

Again, the 1DIII will perform better in low light--both at higher ISO's and in terms of AF.

And for the glam stuff. 20x24 prints from the 1dm3 possible? (that look good obviously) as I said, these prints aren't done often, but they are done. Same with posters, though I don't think those are printed directly from my supplied file.

Thank you for that additional info.

It's really come down to deciding between the 1dsm2 and the 1dm3!!

Well.... Just pulled the trigger on the 1DMIII. Should be here next week. Ordered a used LN one from KEH, $2800 Sooo Hope it was the right choice! Gets freaky going down in MP and off FF!!!

Thanks everyone who took the time to try to help me make this choice!!
