I've got the 24-70 F/4 a couple of years ago to use on my 1Ds II and I love it. (also have the 17-40, 70-200 F/4 IS, 50 F/1.8 and 85 F/1.8) It's sharp across the range, starting from F/4. I'm not a pixel peeper, so it can be that 50mm is a bit less sharp as some test say. It does have a bit distortion as Canon EF 24-70mm f/4 USM L IS - Full Format Review / Test Report - Analysis says, but for critical photo's, the distortion can easily be corrected using Canon DPO. (Just like any modern mirrorless does) Never used the F/2.8, but what I love in the F/4 compared to the F/2.8 is the image stabilizer and the fact that it's a quite usable macro lens. (and of course it's cheaper and lighter)

<p>$400 for a 1D Mark II can't be beaten I think. I've bought a 1Ds Mark II two years ago for the same reason. The only thing those bodies are lacking compared to more modern bodies is high ISO noise and maybe pixel count. (and dynamic range for those who like to pull shadows 5 stops)<br> AF speed is spectacular which might be very important for you too. And they can withstand rain and dust.<br> Be aware that if it breaks, it probably can't be repaired.</p>

<p>I would recommend the 70-200 4.0L non-IS. Excellent lens for portraits and can be bought reasonable cheap second hand.<br> @Bob Atkins: I don't think "zoom with your feet" is a good advice for portraits because by moving closer or further away, you change perspective and that has great influence on a portrait. Zooming is more comparable to cropping.</p>

<p>Wouldn't a ND filter help for flash usage too?</p>

<p>I guess the OC-E3 is just a dumb electrical extension with no active parts, so you should be able to check it with a multimeter: check that every contact is connected to the contact at the other side of the cord and that it isn't shorted to any of the other contacts.</p>

<p>I've got the Phottix variant and use it only occasionally. I really like it because it works great and has a good working distance, so I think it's definitely worth buying batteries. Both units need batteries.<br> Removing the batteries when not using them is a good idea, since they can be turned on accidentally when stored in a tight bag.</p>

<p>Another solution could be to use a neoprene camera strap: with such a strap, it really feels like your only carrying half the weight.</p>
