<p>Ive heard the detail is suppose to be outstanding but as long as the AF is reliable it will be better :P The main thing is you have confidence in using it.</p>

<p>Nick,</p>

<p>My MkIII AF is spot on. I took 2300 shots at a three day event last week with complicated AF requirements and tuning. 133 images got thrown away due to focus errors and of those most were my fault, either miss timing initial acquisition, failing to press the AF button or general incompetence. So in real world use out of 2300 shots I probably lost 50-60 due to the camera AF. Back in the film manual focus days I was happy with a 3-4 image per roll keeper rate.</p>

<p>My MkIII is returning a 97%+ keeper rate with regards AF. My best keeper rate in MF film days in similar situations was around 11%.</p>

<p>Hi,<br /><br />I have never been happy with my Mark 3 for sport. I do top end soccer in the uk and europe . I use my 2n's which I find better for me then the mark 3. The great thing about the Mark 4 is that strait out of the box with only a few corrections I was getting better quality pictures from my old cameras . Not only in floodlight conditions but in normal light. It read the image with a sharper edge on all my lens from 400 mm f2.8 to 16 mm 2.8 . Each sport is very different and football(soccer) has many different angles and option within the game. We do not live in the film world for sports any more , so looking back is not an option. It is very true being confident in your gear and also keeping up with your fellow photographers in a pro market . Missing a picture is not a option if you want to get top quality work. <br /><br />Love to see some of your work Scott. Also your custom function for your focus on the Mark 3.<br /><br />thanks,<br /><br />marc</p>

<p>Hi Marc,</p>

<p>I only referred to the film era to show how far we had come, not because I think we should go back. Images are missed by photographers every day, life does not depend on it, it really doesn't, the key is to be in the right place often enough to get enough shots to make it. Obviously a lack of confidence in your gear can make you miss more than if you are using gear you are more familiar with or that works better for you. No doubt some MkIII's did have issues, maybe yours does, but mine works way better than my MkI and II's.</p>

<p>I was using two different 300 f 2.8's and two 70-200 f2.8IS's so the micro AF adjustment that I normally have on was off. AF settings as below,<br>

C.FnIII 1:0/2:-/3:0/4:1/5:0/6:6/7:0/8:2/9:2/10:0/11:0/12:0/13:0/14:0/15:0/16:-/17:- C.Fn III 2: is set to midpoint</p>

<p>The event I covered was a sailing regatta, I was in a small press boat and the weather was variable, obviously both our boat, and the competing boats, are traveling in different directions on the choppy water, the closing distances and directions are very variable as close passes are made. Both these images are untouched, as are the 100% crops, on screen as native files they are razor sharp even before post processing, but please appreciate they lose a lot in the jpeg and save for web actions. One of the most difficult, for AF, problems in this kind of thing is jumping from the intended subject to an unintentional one. In the first image the boom is a typical example, I focused on the guy on the rail but the boom could easily upset it, expanding points with ignoring closer objects works perfectly. The second example shows a similar situation, DOF was far too narrow to include everybody, but I told the AF to prioritise the helmsman and it did. You can see the cockpit etc in the reflection in his glasses, that is 17 odd meters away with a very variable motion track. I won't win any awards with it but the AF did exactly what I asked it to.</p>

<p>But you do have to tune it for different events, have you seen this pdf? eos1dmk3_af_cfn_guide.pdf . There is a specific soccer setting that is close to my yacht racing. Also I like the Group settings function for different situations.</p>

<p>Hope this helps, Scott</p>
