Nice! Add a built-in 1.4 TC and that would be really something. On that note, why aren't more lenses coming out with built-in TCs? Especially the f/2.8 varieties. Other than the slightly inconvenient hit to the sticker price, of course.

Sadly, no built in TC. They seem to have the space, even removing the drop-in filter (now need a front filter).

I am very much hoping that Canon does start having more lenses with built in TCs. They were the first, but now Olympus has a 150-400 with a built in 1.25 TC (for micro 4/3rds, so equivalent to 300-800 native, and up to 1000 mm with TC). Then Nikon has their new (and expensive) 400 and 600 with built in TCs.

Canon was the first, from what I can tell, the 100-400 f/4 TC was popular, so hopefully they come around.

To me, that is exactly what this lens needs, something like a built in TC. It would have added weight, sure, but so much more functionality. The problem is options. The 70-200 f/2.8 is much less expensive and much smaller/lighter but doesn't accept TCs. So, what you are paying in money/size/weight for is 200-300 f/2.8 and the ability to add TCs.

I have a feeling, there is a group that really wants this lens: indoor sport photographers, parents with tween kids and all their functions, etc. That is just not me. If I ever start doing really expensive trips where I want a second lens, I could see this being an alternative. Having a 140-420 f/4 is actually pretty enticing. But, nothing on my current radar where I think I need to preorder this.
