Why The EF 200-400 f/4L IS 1.4x Delay?
« on: November 13, 2012, 07:59:43 AM »
The million dollar question….
We’ve been banging on the proverbial doors trying to find out why the known EF 200-400 f/4L IS 1.4x has yet to be officially announced, priced (it’s going to be $10,000+) and made available to the  people that need it.

The latest we’ve heard, and from a pretty knowledgeable person is that the lens has needed a redesign in regards to the “bump” that holds the built-in 1.4 TC. The person wouldn’t elaborate as to why it was an issue, but it was brought to the attention of Canon at the Olympics that some pros were complaining that the “bump”, or a function of the “bump” got in the way of something. Again, what the something was wasn’t elaborated upon. If anyone out there knows, I’d love to hear it.

This is about the only explanation I have received beyond “manufacturing issues”, which could also be playing a small roll I suppose. However, lately we’ve seen that the new super-telephoto lenses are now making their way to “in stock” status around the planet. Maybe we’re closer to the new supertelephoto finally being announced.

Sorry we can’t be more conclusive on this one, this is the best information we have.

It couldn't be that it is in the way when dismounting the lens?

I would think so, I've heard that there is some issue with the teleconverters movement with dismounting.

$10,000 + price tag.
No need for Canon to hurry on my account.

...

The bump is one the same side as all of the knobs as things that you want to change. For the average shooter that has their right hand on the shutter button and left hand on the lens, I can see it getting in the way as you move your hand along the lens.

Even its proximity to the on-off knob for the TC might be such that it is hard to turn the know whilst you've got your eye up to the camera because you can't really approach the knob with your hand against the lens. When you have the camera+lens down, I can see it being easier to get at the knob... but then how easy will it be to turn that knob when wearing big gloves with that bump there in the cold?

I can easily see them moving the bump to either be on top or on the other side of the lens.

On that side of the lens, it could easily be getting in the way of almost anything. It really needs to go on the top side of the lens as the only thing that it could then get in the way of is flashes and the lens is too long for that bump to be of significance with flashes that would be impacted.

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.

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...
What is truth?

Here is the link, sorry, only Chinese version is available. ;D

Why is someone paying $10k on this f4 and not getting the 400 f2.8 mk.ii ?  (Unless they can afford both...  :P )
