Also, has anyone else noticed that if this were a 7D or anything else with flash, and there were a CPL in the filter slot, it would be mighty-hard to squeeze your finger in betwixt the flash and filter to actually turn the thing?

Maybe the 'bulge' in the rumored issue isn't the bulge of the TC, but the bulge of a popup flash?  The flash on APS-C bodies interferes with TS-E knobs - my 24mm II came with a smaller substitute knob for that reason. Might be the angle, from the pic I'm not sure you could even swap the drop-in filter with the lens mounted on a 7D.

I was thinking that it would be nice to have the 200-400 f4 an an every now and then use lens, but that's not going to happen if its going to cost $10K. I thought it would be closer to the price of the 70-200 II or 24-70 II.

Speaking of that. I see that these lens types of lens are commonly used for sports, but who pays for these pictures to justify the price of these lens? Especially when it comes to wildlife.

I can imagine the AF/MF and AF range limiter switches are a little hard to get to in a hurry, esp on a pro body?

Looking at that image, there is a lock on the TC, but I wonder if it hits a Wimberly head??  That would be a show stopper for sure.

Is the image shown the actual product image of the lens?

There is a better way to spend that money if I really want this zoom range.

I'm starting to think this lens is a bit too much of a swiss pocket knife. Too many features, too little space.

I think it would be beneficial to drop the built-in TC as mentioned earlier. It's nice as a commercial stunt, but a 200-400 without it will be more reliable and most likely sell more units, especially if it's priced to beat the Nikon version.

What actually happens to these 'demo' lenses, will they all go back to Canon eventually?

Just a thought - I wonder if they tried to build a "Drop-In" Tele-Converter?  That way there would be no bump.  Space would clearly need to be bigger than a DI Filter and optical alignment might make it impossible ... but it would be interesting.

Other than the filter I could imagine accidental body/lens detachments happening when changing focusing modes and MFD.

But then again Canon has already made warnings about the body bulge for other lenses like the TSE 17mm.

Something tells me that the solution to this is not going to be anything to do with redesigning the 200-400.

They'll probably use it as an excuse to leave the inbuilt flash off the 7D mk2 and 70D "for our own good"...
