Canon 200-400 F4 1.4x extender anounced!

Pretty sure you're thinking of the 200 f/2.0.

I agree that the 100-400 is pretty versatile for what it is. However, I think my 70-200 f/2.8 non-IS + 2x TC II is a bit more versatile, and it's about a wash on price (used). And as far as not being able to touch the 100-400, we can agree to disagree on that one.

I also don't like the 'pump' action of the 100-400. And I know that it isn't really a dust pump, I just like the internal zoom action of the 70-200 better.

Like I said, it's nice to see Canon bringing out a super-tele zoom, I just wish it had been done differently. If they announced a 100-400 f/4, I'd SERIOUSLY re-evaluate my decision to purchase a 300 f/2.8.

You say you would buy a 100-400LF/4 instead of a 300f/2.8? The 300 costs a lot more of course but isn't it still better than the 400? I mean you have 1 stop more but 100mm extra so actually *EDIT*, it would be better

If it costs over $2500.00 it costs to much IMO.

Not the lens for you then

Well, if a significant thrust of your work would benefit from 300mm f/2.8, then you'll get results that just can't be achieved with an f/4 zoom...

400mm on a 1.6x body is still 400mm. sensors do not change lens physics...

Can I use a 1.4x extender?

are you serious? you want to stack an outboard TC onto the one already built in? I guess the answer is yes but the results are bound to disapoint...

I don't know if I want to, but I must admit I was wondering the same.

A 392-784 zoom lens sounds interesting, but probably not at f/8 and I'm guessing you'll have to stop down to get a sharp image (if at all possible)

The alternative would be to leave the on-board teleconverter turned off, and use the 2X III on the lens. 400-800 f/8 IS. Hmmmnnn....

or use the internal plus 2x so you have a much less usable 560-1120 f/11 hmmm... lol

the most awesome part about any of this part of the discussion is that SOMEONE *will* do it once this lens hits the market

I wonder if they'll discontinue the 100-400??

I doubt it. How many Canon EF 70-200s are there?
