so it can be the wrong thing to have if you want candid shots

But, ...having just switched from the 7d, I find the extra stop or two in low light performance allows me to grab 'party pictures' easier - the AFalso works better in low light, so I can grab a quick candid w/o flash.  Maybe not always 'publishable' but good enough for web-sharing those moments your friends  may or may not want to memorialize  :)

Just rented it 2 wks ago and fell in love with it (c/w my 7D), so I bought it :)

Agree with Neuro - excels in low-light/high ISO
Here is a sample photo in a terribly lit indoor gym (concert hall) with the 1DIV at iso 12,800, using the 70-200/2/8L IS II on a monopod at 2.8. 1/1000 (Tv) and minimally processed with Adobe Camera Raw.

Check out Think Tank Products   www.thinktankphoto.com
I got a Retrospective 30  They have a Hugle selection of Products

+1
It holds both a 1DIV and 7D gripped, 16-35/24-70/135 (or 70-200)/35 + flash and doesn't look like a camera bag and stays upright when you put it behind car seat/in trunk or on the ground.

If carry-on roller bag is more your style, look at the Airport security.  I have the International and just a little too small for 2 bodies and the laptop.

EOS Bodies - For Stills / Re: 1DX vs 1D IV ??

As the OP, I again thank you for your insights - I didn't have enough time last weekend to fully explore the AF of the 1d and (mistakenly) undervalued it c/w my 7D. I trust the additional time I will have with it (now that I hit the "Proceed to Checkout" button  :) ), will allow me to better compare all of these options.  I also trust the incremental ISO / noise performance over the 7D will allow me the freedom to push my low light vision.  Ultimately, as so many others have said, why wait?  It is a great camera and I know I will be using it ALOT between now and whenever I might be able to get my hands on a 1Dx (as I have been unable to secure a pre-order). Again, thanks for helping me decide.

If you have no plans to upgrade to FF, then gripped 7D with the 17-55 2.8 EF-S IS should definitely be on the list - would overlap your current kit lens, but the 2.8 proves invaluable in your situation.  Not an L - but behaves like one I'm told.

If you are allowed to move around the playcourt then you can manage with primes like 85mm f/1.8 and 135mm f/2.

Ditto ...The 135 on a 7D crop gives plenty of indoor reach...

(I think) Dr Neuro explained fairly persuasively that the x1.3 crop on the 1D4 vs the FF 1DX is essentially meaningless. Cropping a 1DX file in post to a x1.3 value will deliver a file almost indistinguishable from the 1D4 file. Want to chime in here Dr Neuro?

No chance of this i'm afraid
have a look at the iso samples indicating the crops here with the 18MP vs 16MP
http://www.thedigitalpicture.com/Reviews/Canon-EOS-1D-Mark-IV-Digital-SLR-Camera-Review.aspx

edit: if you apply a 1.3 crop to the 1Dx resolution of 5184 x 3456 you get 3987x2658 which is 10.6 MP or basically the 1Dmk3

The ISO samples on the TDP review aren't relevant to this issue - those are scaled equivalently across sensor resolutions (i.e. the more MP, the bigger the image).  The issue being discussed is what happens when you crop the FF image to the FoV of a 1.3x crop, or even a 1.6x crop.  The answer is that for approximately equivalent sensor technology, the images aren't too different in terms of IQ, although obviously with the cropped image you end up with far less resolution after cropping.  The crop magnifies the effect of IS noise, alters the DoF along with the framing, etc. 

Put another way, if you buy a FF camera but then have to crop all your images to 1.3x or 1.6x FoV, you're throwing away the IQ advantages of FF over the smaller sensors, and so you might as well just get the cheaper camera (from an IQ standpoint).  Conversely, if you only need to crop a few of your images, the IQ with the FF will be a decided advantage.  That might mean getting longer lenses to compensate for the loss of 1.3x crop...which suits Canon just fine...

So if I am able to frame what I need with FF or the 1.3, then my IQ (image quality, not my intelligent quotient :)) will be NOTICEABLY improved over my 7d images?  I am not a pixel peeper but when I enlarge posters to 16x24, should I expect cleaner/sharper images, or at this size, is it only a theoretical advantage?

Appreciate all the feedback, but would like even more personal experiences with the ISO/AF 'differences' between the 7D , 1dIV and speculation about the 1Dx. 

With only a single weekend's experience with the 1dIV, swapping back and forth with 7D, I didn't see a DRAMATIC improvement in capture rate of the AF with 1dIV.  Shooting moving targets in the 'dark', I use ZONE selection with the 7D sometimes, and overall I don't miss many shots b/c of AF.  However, with all the individual points on the 1dIV, it seemed to take me longer to cycle through to where I needed them.  Maybe I just needed to get more familiar with the 1dIV? but i missed the ZONE and 4 point expansion options.
To be sure, the 1Dx is bringing the AF to a new level, so that is definitely a plus there over the 1dIV.

With respect to ISO / low-level performance though, I obviously saw improvement between the 7D and 1dIV.  Shooting with the 7D at max 3200 mostly, I have come to deal with the noise, but am limited in really dark gyms.  I was able to shoot 4000-12,800 with 1dIV in this dark environment, but did have quite a bit of noise, most of which cleaned up in ACR pretty well. But with hundreds of shots, it does take time.  What I should have done was take the same type shot with both bodies at the same ISO to compare noise but this was my first 2 body shoot and I was simply too busy focused on having 2 different lenses/options available and didn't really plan enough on a head-head comparison, my bad.

Will the 'improved' 1Dx ISO performance mean:
1).  I will have less noise to clean at 2000-3200, or
2).  I will be able to capture shots in the dark gyms where I currently don't get anything very usable.
3).  A little of both (?) 

Other features/benefits aside, how much better can we expect the 1Dx to (out)perform the 1dIV ?  With my shooting style and gym limitations, I can accommodate to the FF vs 1.3 vs 1.6 reach / lens issues with my arsenal, and I am improving my positioning and shot planning at every venue, but I am wavering as to the real-world improvement in the image quality.  Both will be better than my 7d, but HOW much??

EOS Bodies - For Stills / 1DX vs 1D IV ??
« on: January 18, 2012, 08:21:47 PM »
Had the guilty pleasure of renting a ID IV this weekend to serve as a second body (to my 7D) to shoot indoor volleyball tournament.  While I am not a paid professional (yet), I am striving to take me vision to the next level, and despite nice lenses, the low-light challenges continue to plague some of my shots with unpleasant noise. While I think about light, in my world I cannot control it very much, so I am forced to think more about my gear ;) but only in so much as it helps me achieve on paper (and computer screen) what I 'see' in my mind, and what my clients (players/parents/coaches) can treasure forever.
While I was able to get more 'usable' shots with the 1D IV in the higher ISO ranges (4000-12,800), I'm curious to the potential of the 1DX in this setting vs the 1D IV.  I have not yet seen output from the 1DX, and wondering should I expect $2K 'better' high ISO performance.  I have almost weekly tournaments to shoot between now and June, and am debating whether to take the plunge now and get my own 1d IV or 'tough' it out with only a single body till the 1Dx comes out.  I also have the trip of a lifetime this August (Galapagos Islands) and will 'need' the second body there as well.  Are the 7D and 1D IV too close in function and therefore should I wait till the FF 1Dx is available?? While both pricey, the 'extra' $2K has me wondering how much more useful the 1Dx will be c/w the 1D IV ??

Here are some of the comparison shots with this lens on both a 7D and/or the 1D IV  Different Gyms with different lighting but both shot with Tv mode, autoISO so more real life than technical comparison  :)

135/2  1/1000 Tv ISO 3200 on the 7D

Gorgeous pics ! Once I get a FF the next buy will be this beauty 135 f/2 L ! :-)

No need to wait for FF, the 1DIV and 7D photos from above show what this lens is capable of....
