Ok, can you find me a 300 mm f/1.4L IS lens for night football then?  :P

There is never enough light for me.  I do low light photography, and ISO 12,800 is not fast enough.  I tried getting by with a f/2.8, but its always wide open and struggling with shutter speeds that are too low.  The 5D MK III is about 1/2 stop faster than my 5D MK II, and a little better at 12800 than my 1D MK IV.
 
I'm now waiting for the results to come in for the 1D X to see if its worth the money to upgrade.  It looks promising, but reliable testing is still to come.  In addition to my 5D MK III, I tried a D800.  It is ok at ISO 12800 if I add a lot of nr, but its strong point is for iso 400 or less.

I'm giving somewhat serious consideration to a 5D3.  Because I shoot sports, my constant struggle is to get enough light to keep the shutter speeds as high as I need them.  So I've always looked for the fastest lenses I can get, with f/2.8 being the minimum.  Of course with a fast moving target, when the DOF gets too thin, even the slightest miss on the AF starts to show, so it's a bit of a two-edged sword.

So the question is, with the great ISO available on the 5D3, will I start to be better friends with my 24-105L and can I consider the 17-40L (both of which are f/4.0) or should I still stick with the faster lenses?

If you're going to shoot sports with the 5D Mark III, I'd consider a few things.  For basketball, I'm using a 135L and a 200L, with a backup 85 f/1.8 for sideline/under the basket shots.  All are f/2 or wider.  I don't shoot anywhere near f/2 though.  These lenses just happen to have the ability to focus quickly.  I stop them down quite a bit actually, set my shutter speed to 1/500, and ISO to about 3200 or 6400 on a 5D III I'd guess.  I try to shoot around f/4 to f/6.3 in indoor lighting, with sufficient ISO to maintain 1/500s shutter speed.  Preferably outdoor sports it's easy to shoot 1/800 or 1/1000, which is better.  Since you won't likely shoot wider than f/4, the actual aperture is not the issue, it's the focusing speed of the lens itself, as well as focusing accuracy.  This is where the 135L, 200L, 300L, 400L all accel.  Obviously you don't need the 300's and 400's for indoor sports, but for football you would, and also track and field. 

Given all of that, higher ISO settings on the 5D Mark III will actually outperform my 1D Mark IV in comparison tests in similar lighting.  For instance, my 5D III's outperform my 1D4 at ISO 6400 by quite a bit it's looking like, so your camera should be great.

The 5D3 & the 1D4 have both modified my lens requirements with their amazing high iso performance. I value rocket fast AF so I look to f/2.8 as a practical limit. My 300 f/2.8 focuses way quicker than my previous 300 f/4. But at the wider end of the equation, I find reduced need for f/1.4 lenses. I've replaced my 50 f/1.4 with an f/2.8 40mm (McShorty) which is SHARP wide open. My 24-105 f/4 is getting a lot more use than it used to. My copy is sharp wide open too, though I will pick up the new 24-70 f/2.8 when it ships.

Yesterday I did a job for a university shooting in a big lecture theatre. I shot with the 5D3 with 300 f/2.8 at 12,800 iso. You can't afford to underexpose, but when the exposure is perfect which is not hard with 5D3 metering, the results just knock my socks off.

Hi PW....how do you like 40mm shorty with 5D III so fall?

So far so good. I'm not expecting $1500 L performance from it. But it's centre sharpness at f/2.8 makes it highly usable at that aperture. It kills my 24-70 f/2.8 at f/2.8 but that would not be hard. Corners can get a little mushy at f/2.8, but this is not an issue for most subjects I shoot. There is noticeable vignetting at f/2.8 but this is quickly fixable in LR4. Soon the fix will be automatic when LR4.x is released with updated lens profiles. I have an LR default set up for automatic lens correction on Import. Stopping down to f/4 ramps the IQ right up with f/5.6 delivering excellent results right across the frame.

Let's not forget the indisputable fun factor of such a tiny lens. And I just leave it on the body as a functional bodycap!

HTH,

Thanks for the info PW. The reason I didn't buy this lens because my 50mm f1.4 is SUPER SHARP at 2 - 2.8 and I love the bokeh on my 50mm.

CAN'T WAIT for my 24-70 mrk II....did you have this on pre-order yet?
