Canon EF 100-400 f/4-5.6L IS [CR2]

Canon EF 100-400 f/4-5.6L IS [CR2]

More information
Now that the EF 24-70 f/2.8L has been redone, the most requested lens to be replaced with a new version is the Canon EF 100-400 f/4.5-5.6L IS.  A few patents exist for a new 100-400, you can see them here and here.

The lens isn’t for an immediate announcement, as we’re told they may be waiting for Nikon to announce the much needed replacement to their 80-400.

We’re told 2 designs currently exist for the lens, and at least one of them has a zoom ring instead of the polarizing “push/pull”. The lens is also said to be weather sealed, slightly faster starting at f/4, a bit heavier than the current version and has the latest and greatest IS system.

This lens could also be considered the IS replacement for the EF 400 f/5.6L, especially if it’s better optically. I’m sure this point may not be what a lot of people wanted to read.

No mention of a timeframe for an announcement. I suspect it’ll be after the 200-400.



What’s Next? A General Breakdown

What’s Next? A General Breakdown

Ready yet?
The excitement around the 5D Mark III, EF 24-70 f/2.8L II and 600EX-RT was on a level that I have never seen. It’s going to be pretty hard to top in the future, maybe the 5D Mark IV will be able to do it.

However, there’s always “what’s next?” when it comes to gear in the ever advancing photography and videography world. So I may as well get right to it.

On the immediate horizon
I don’t have an exact announcement date for the gear below. I do expect these items to be the next SLR related gear to be announced.

– Rebel 650D/T4i
I haven’t received any specs of the camera, just proof that it exists and it’s coming soon. I expect DIGIC 5, articulating LCD and new movie features.

– EF-S 18-135 f/3.5-5.6 IS II
A second version of this lens already? That’s the word. This time it will come with a silent autofocus motor, perhaps as part of a new video AF feature in the Rebel T4i. I wouldn’t expect anything revolutionary in that regard considered the 5D Mark III and 1D X didn’t get anything advanced in that regard.

– EF/EF-S 40 f/2.8 Pancake
No word on the mount for this lens, but it’s coming and it’ll be quite inexpensive. Sub $200 I’ve heard.

– EF 200-400 f/4L IS 1.4X TC
This lens still hasn’t become an officially announced product. The rumored price tag is between $11,000-$12,000 USD.

Sometime in Quarter 2 or Quarter 3 2012
There are going to be some more gear announcements heading into Photokina 2012 in Germany. I have heard between 10-13 lenses will be announced in 2012 from Canon. No word if that includes any lenses for the predicted mirrorless camera.

– EF 35 f/1.4L II
This is the next likely prime candidate to be released by Canon. No word on an announcement date, but preproduction lenses exist.

– EF 100-400 f/4-5.6L IS II (the current version starts at f/4.5)
I’m told this will also arrive sometime in 2012. It will be a replacement for both the 100-400 and 400 f/5.6L. If it performs like the current 400 f/5.6 prime does at 400mm, then we’ll have a winner.

– Cinema EOS DSLR
I haven’t heard anything more about the 4K DSLR Canon said they were developing. There is speculation that it will appear before NAB 2012 in April. Nothing can be confirmed on that front.



Canon EF 100-400 f/4-5.6L IS in 2012 [CR2]

Canon EF 100-400 f/4-5.6L IS in 2012 [CR2]

Canon 100-400 f/4-5.6L IS
Received word that we can expect to see a direct replacement of the aging EF 100-400 f/4.5-5.6L IS sometime in 2012. It has been rumored quite often that a replacement was coming. Some of those rumors may have been talking about the EF 200-400 f/4L IS 1.4x.

We have the patent from a few months ago to get an idea of the optical formula.

I was told it would be in the $3000 price range, have a rotating zoom, weigh less, be slightly faster on the wide end at f/4 and carry the latest and greatest coatings and IS.

As with most lenses, an exact announcement date is unknown at this time.



Canon EF 100-400 f/4-5.6L IS “Soonish” [CR2]

Canon EF 100-400 f/4-5.6L IS “Soonish” [CR2]

Finally on its way?
I was told today that a new EF 100-400 f/4-5.6L IS will be making its debut “soonish”. It will be after the EF 200-400 f/4L IS 1.4x is officially announced.

It could be tested at Euro 2012 before being announced.


  • Ring zoom (not push/pull)
  • Latest IS System
  • 82mm Filter Size
  • Weather Sealed
  • Slightly heavier than the current model
  • Slightly faster f/4 at 100mm (Current is f/4.5)
  • Retail around $2800 USD

CR’s Take
A few folks want an EF 400 f/5.6L IS, I’d think this sort of product would fill the void. I’d expect it to be optically awesome.

This comes from a pretty solid source, though lenses are always hard to nail down.



Another EF 100-400 Patent

  • Spherical aberration is proportional to the fourth power of the high on-axis ray
  • In focusing heavily on the object side to move first, counting from one group behind, which varies significantly higher on-axis ray
  • Canon’s patents, and by fixing the first two groups, counting from the back of the eye movement to limit the amount counted from the first team back, suppressing the fluctuation of spherical aberration

*UPDATE* More 5D Mark III / 1D Mark V & Lenses [CR2]

*UPDATE* No IS in a new 24-70L ?
A couple of folks have come forward and said we won’t see IS in a new 24-70L.

Remember this patent? There’s no IS.

5D Mark III
Some more clarification about the upcoming 5D Mark III. It will be moving a bit more high end with an improved 7D AF system. Expect it November/December 2011.

1D Mark V
The next version will be moving into the 1Ds territory as the new high end digital SLR. Expect it to be fullframe by the sounds of it. Late 2011/early 2012. No specs finalized yet.

24-70 f/2.8L IS
It’s coming and will be announced with a camera body at the end of 2011. I haven’t heard a peep about the lens in a while.

An interesting tale about this lens. Apparently the replacement has been canned and is being redesigned.



100-400 Replacement

What’s going to replace it?
This is rumor and opinion in regards to the 100-400 replacement. I had a chat with a friend today and he gave his 2 cents about the new 70-300 and the 100-400.

What if the new EF 70-300 f/4-5.6L IS is in fact the new 100-400? Since we’re dealing with crop factors now. The new lens costs $100 more than the 100-400 does at B&H.

We’ve heard about a replacement of the 100-400, but what if it isn’t a direct focal length/f-stop replacement?

The first thing that comes to peoples minds is a 200-400 f/4L IS. While a fabulous lens from Nikon, it’s expensive. How many $6000 lenses are they going to sell?

I can see a 100-500 of some aperture in the $3000-$3500 range. It would require a focal length longer than 400mm to make it a worthwhile “upgrade” over the new 70-300.

It was an interesting conversation and I think there could be something to the concept.



EF 100-400 Version 2 Coming [CR2]

Coming in 2011
An email showed up this evening confirming a new 100-400 will hit the world sometime in 2011.

NL also received the same information in person at an event in London.

No word on zoom design.
