I haven't had this problem myself, but according to search results on the Internet you could try checking your flash settings using the camera menu:

Menu->Flash control->External flash C.Fn setting->Flash metering mode (tab 5) and set it to E-TTL II.

Hopefully that works...

<p>Mark A, great colors on your first photo! These are some photos I shot near a local pond...<br>

<p>Ruslan,<br>

<br />You are right about the recorded sound. It only gives you an idea. Maybe you can rent a 5DMkIII for a day? That way you can compare it with your friend's MkII. </p>

<p>Ruslan,</p>

<p>You can listen to the shutter sound of the 5DMkII and 5DMkIII (single shot, continuous, silent mode) on:<br>

Does the additional stop of the F/2.8 70-200 compensate for the additional weight? In my opinion it's hard to say, since it depends on what you or I consider as heavy. Maybe it might be a good idea to rent the 2.8 if you haven't used it before. Then you can decide whether the extra stop compensates for the weight.<br>

Personally, I love my 70-200 f/2.8 IS USM II and have no problem holding it steady, but it's you who has to carry it. Perhaps a BlackRapid strap could be useful so you wouldn't have to carry it all the time?<br>

Good luck on the decision, both are great lenses...</p>

<p>I have my 100-400L for about a year and haven't noticed any dust problems. It's a nice lens, and you would have to pay a lot of money to get a Canon lens with a greater focal length. Renting the lens for a day is a good idea since it will get you familiar with the push-pull design.<br>

Enjoy the 100-400!</p>
