Thanks for sharing.

I am pretty impressed how well it is at f4 already. especially compared to the 16-35 F/2.8L II

If I would go more into this focal range, I definetly would want it. Having the 17-40L already, it's too much money to spend. But maybe someday... *sigh*

Yup, in terms of IQ, this lens just blows away the 16-35 and 17-40.

If you've still got one of those two lenses, you could try giving it away for free because they're not really worth having now.

Unless you are a professional that does events.  Better corner sharpness from f/4-f/8 is not worth losing f/2.8.  IS can't help motion blur.

Lets see. The trade off is 1 stop of ISO for sharp across the frame.

And if you need 24/28/35 at f/2.8, Canon now has three primes with IS.

Dilbert, I agree with your tradeoff math and will probably buy the new lens, but if you are shooting moving subjects, sharp corners mean little if your subject is blurry from too slow of a shutter speed.   :P

+1

I have the 70-200/2.8L IS II instead of the smaller/lighter/cheaper f/4 version for the extra stop of shutter speed.
EOS 1D X, EOS M2, lots of lenses

Lets see. The trade off is 1 stop of ISO for sharp across the frame.

And if you need 24/28/35 at f/2.8, Canon now has three primes with IS.

In the range I personally have in addition to the 16-35mm f/2.8L II, the 24mm f/1.4L and a 35mm f/2 IS USM.  But, neither is a zoom (helpful at receptions), and neither can do 16-23mm.  I also have the 24-70mm f/2.8L II, which is a zoom - but once again cannot do wider than 24mm.  Hence, the importance of the 16-35mm f/2.8L II.  I don't want to be stuck with the limitations of a f/4 lens.  Also, the corner sharpness is unimportant when taking pictures of people as you need to put them in the center of the frame to avoid perspective distortion anyway in most of this focal length - center sharpness is far more critical.  Also, IS for my needs is virtually useless below 70mm as my shutter will usually be 1/100 to avoid motion blur.

Believe me, if I didn't think I needed f/2.8 on the 16-35, I would sell the f/2.8L II on eBay as even today it sells for more used than the 16-35 f/4 IS costs new at full MSRP - I would essentially be able to do a swap with no net loss.  But, I don't want to be put in the situation where I need 16-23mm f/2.8 and have to take a compromised picture because I don't have it.

Finally, note that the 16-35 f/2.8L II is actually sharp across the frame at f/11 (and pretty close at f/8).  So if you have this lens, all you have to do is stop down - which you probably would be doing for DOF in landscape anyway.  f/4 is really where the 16-35 f/2.8L II gets trounced in sharpness by the 16-35 f/4 IS, but that is the aperture that would likely be least used by either event or landscape photographers - too slow for event photographers, not enough DOF for landscape.

Have a look at these comparisons at F/11, though.
http://www.the-digital-picture.com/Comparisons/Canon-EF-16-35mm-f-4-L-IS-USM-Lens.aspx
(mouseover the aperture values to see the pictures change)

I would not call that "sharp across the frame" for the F/2.8 lens.  At 16mm, the F/4 lens is very slightly better in the corners at F/11.  And at 24mm and 35mm, it's clearly better.  The new zoom even fares well against a Zeiss prime on that same page.

The one distinction is why a boatload of landscape people will buy the new F/4 lens. No Canon UWA zoom has delivered sharp corners... until possibly now.  I'd like a few more reviews corroborating TDP's findings, but I'm optimistic.

I'm confused. I thought it was an EF mount lens:

Quote from: photographyblog.com
It has no aperture ring, which is no big deal unless you wanted to use it on a very old film body.

Every review/poster of samples has shown similar IQ.

(inferring what you meant) similar IQ... between the two lenses?   

If so, I refer you to my prior post.  I think Carnathan's shots show a clear corner sharpness improvement for the new lens at 24mm and 35mm -- even at F/11.  At 16mm, I'd say the shots are a pretty much a draw if you stop down to F/11.

(if that's not what you meant, apologies -- wasn't sure)


And we should expect a sharper lens based on those MTF charts, right?

It's pretty awful how littered that photographyblog is with ads. I understand 1 or 2 subtle ad placements for revenue, but that page looks like trash.

And here's my super quickie sharpness offering.

I didn't have a 16-35 to compare this against, so I compared it at 24mm against my 24-70 F/4L IS.

Approach:

* Both lenses set to 24mm
* Taken at F/4, F/5.6, F/8, F/11
* Tripod, cable release, LiveView focusing, etc.
* Aperture priority @ standard exposure
* Did not have peripheral illumination on
* RAW processed in ACR, sharpness set to 50 and everything else was default;  no lens correction profiles were used

https://www.flickr.com/photos/66374817@N04/14546466862/sizes/o/

What you'll see here are the actual 1000x1000 pixels in the corner of images captures at four different apertures on two different lenses.  Make sure you click on the 'original' size at the top to see this without downsampling problems.

Note that at 10x, I was focusing on the boards of the bench, not the ground behind the bench.

Clear limitation:  I was in a mad rush (the rental is due back tomorrow) so I shot a scene without a clear near-infinity planar target (like a house).  It was a park bench that was within perhaps 5-6 feet of the camera.  So I actually LiveView focused at 10x in the corner itself (on the bench boards as said before).  So these shots were not center focused -- they represented the best focusing I could get in the corner of interest.

My thoughts were good ones.  The new 16-35 F/4L IS lens out-resolved a very sharp L zoom at 24mm in the corners.  That and my other finding about vignetting with a Lee filter holder...

http://www.canonrumors.com/forum/index.php?topic=21554.msg409701#msg409701

...has me leaning strongly towards buying this lens.
