Why The EF 200-400 f/4L IS 1.4x Delay?

<< < (2/11) > >>

M.ST:
A few people had the chance to test the lens.

Most of them are not very happy with the build quality of the build in TC and the image quality if you add the TC.

I have both TC´s, why should I pay extra money for a build in TC?

My personal opinion: The lens is too big and havy as a walkaround lens compared to the EF 100-400 IS. The solution with the build in TC is not amazing. For the mentioned price I prefer the normal big whites.

this lens is not meant to be a walk around lens.. just like the 400 f/2.8 and 500 and 600 f/4's.. you don't see people walking around town with those unless they have a purpose to.. its meant for sport, wild life, and journalism when you need flexibility and be the fastest possible lens you can get. hence the price tag.
the 100-400 is more of just a general purpose tele that does everything which is why it is smaller and lighter

as far as the TC goes.. its for connivence.. so you don't have to take your body off put the TC on and put your body back on.. Just move the lever and you're ready to go! just like TV lenses (which is what that stems from) it just makes things easier on the fly so you can get that shot more easily

I'm definitely not going to buy this lens, but it has been really interesting following it from the 5DIII spy shots in Africa(or wherever) to the Olympics. There is definitely quite a bit of mystery and speculation about it. I've been wondering why it hasn't been officially announced yet.

bchernicoff:
I imagine that perfectly centering the extender when swung in from the side was a decent engineering challenge.

It would also have to be user-proof such that if the user believed they had engaged the extender, that it did engage and was perfectly aligned and couldn't move on its own even when the lens was bumped around.

Maybe they could just make the poor man's version, a 200-400 f4 without a TC...
