Hell even the predecessor to the 24-70mm the 28-70mm is great lens, some say even better than the 24-70mm.

Oh man...I bought the Mk. I version of this lens on THURSDAY.  *sigh*

This isn't a product announcement.  Also, just because a patent was published, it doesn't mean that the new version is imminent.  Some patents never become real products.  The ones that do can take years to reach the market.

True, but the timing, with rumors of a new body, the DIGIC V news, the expected 5D3 or 1Dx ... this is looking like a kit lens that'll be out this year.

With the added resolution of Canons new sensors Canon is being forced to seriously upgrade all there lenses so that a new level of detail can be resolved.

I agree wit the earlier post that Canon is trading off barrel distortion for additional clarity.  It's a good trade off since the barrel distortion can be corrected and besides sometimes barrel distortion looks good :-)

Expect this lens to be as sharp as many primes!  That's why Canon is betting on this lens being a big seller even without IS.   :)

Although I would still love to see this lens with IS.  Please Canon can we have an IS version.   8)

I doubt very seriously the 24-70 will make it to America as a kit lens. Too pricey.

On top of that, the lenses they announced last year still haven't made it to the market.  They were way behind schedule even before the earthquake/tsunami hit.  Who knows what that has done to Canon's time lines.

Thus, maybe, just maybe, the feedback from the pro's that regularly use the 24-70 is that the extra price & weight of IS wouldn't add commensurate value to pictures taken.

There is some sense to that, though no one from Canon has reached out to any of the other photographers I know, including the ones they sponsor, to ask our opinion about anything they do. However it seems the 24-105 is a more useful range for a video lens so your idea makes total sense, and would diferentitate the two lenses purpose.

I'm not sure why everyone is so hung up on IS on theis lens as shorter lenses doesn't really benefit from IS like long lenses do, and if you have the extra usable apature and a faster chip that should really offset the need for it.

Anybody knows the specs for the 24-70L I? What is/are the difference(s) between the two versions? Thanks.

As a wedding photographer I think think that IS in the 28-70 would be extremely useful.  My experience at weddings is that I just can't get enough low light capability (as i really prefer to shoot without a flash).  The last wedding I shot was shot mostly at 5000 ISO F3.2.  With a 50mm f1.4 lens.  I was still only getting 1/50th of  second. 

I really would have liked a zoom like the new 28-70 with optics almost comparable to the 50mm f1.4 and ideally with IS.  Without IS at 50mm some of my shots where slightly soft, which is a shame as far as I am concerned.

AND... that was not even a very poorly lit wedding.. like I said at weddings you just can't get enough low light capability.

When people say photos are soft, they typically mean that focus was not achieved. That might be because the camera and lens are not properly matched, it picked the wrong thing to focus on or something else but...

Focus not being achieved is different to blur as a result of either the camera or the subject. IS only helps deal with blur because of camera motion.

At 50mm, you should be using the 1.2L or 1.4, which would give you a much faster shutter speed than the 2.8 for the same light.

Yeah I was shooting with the 50mm f1.4 but it's not always practical to shoot at f1.4 as I often need more depth of field than that.  There are only certain shoots you can shoot wide open like that. 

My shots where focused correctly... the slight softness was due to motion blur.

I have shot with the 17-55mm f2.8 IS on a crop camera and gotten crisp shots at 1/20th of  second.

just curious.  WHY do you think that the 55-250 will only be 55-200?

...maybe because of what is written in the patent :-) :

Focal distance f=55.60 – 203.11mm

OH I KNOW I KNOW!!! It has finally arrived!!!! The in-body IS is coming with the new 5D so why bother having IS on the new lenses....... (please Canon make the dream come true)

So? I've taken sharp shots with the 50/1.4 at even slower shutter speeds of static subjects, hand held.

Anyway, you seem to have convinced yourself that you need IS on whatever lens you use, so good luck.

The problem is that at f/1.4, shallow DoF may be a problem for many shots, depending on the subject.  I've gotten crisp handheld shots with the 17-55mm f/2.8 IS out to 0.5 s (although the keeper rate is pretty low).  The 24-105mm f/4L with 3-stop IS delivers the equivalent of f/1.4 in terms of 'handholdability' for static subjects. 

Photographers lived without IS for many, many years.  So...need?  Well, no.  But humans lived without electricity and refrigeration for many, many years, too...  All things considered, I'd rather be able to light a room with the flick of a switch and enjoy a glass of chilled wine...and have IS available at every focal length.   :P

IS Certainly makes possible some hand held images that I could not get without it.

This image was with my 7D and 17-55mm EF-s at 1/4 sec.  I had just received the camera, and for some unknown reason I had the ISO set to 800, which pushed the aperture way high (f22), so there is a lot of diffraction, and there is just a bit of shake.  Ultimately, I was disappointed at the 7D noise, even at ISO 800.  I re-edited the raw file this morning in Lightroom 3, and it does a much better job of processing the image and removing noise, but its still quite visible at 1:1.



On a dark dreary morning, I looked out my back window, and saw our baby goats playing king of the mountain on our horse.  I knew the horse loves goats, but he would not submit for long, so I grabbed my 1D MK III which always has my 100-400mm on it and snapped a shot at 400mm thru the doublepane glass.  I did not stop to setup the camera, so I got the settings as they were, and a  1/25 sec exposure at 400mm.  I was lucky to get the photo at all, the horse rolled seconds later.

Even though the image is not particularly sharp due to shake, my wife likes to show it to her friends.

Without IS, I would not have had time to setup a tripod, or adjust ISO even higher (already at 800).

Why wouldn't you want IS?  If you don't want to use it, you can always turn it off.
