From Photo.net
Apparently Canon is testing a new 28-135 Lens. This is a direct quote I received via email.

Canon is currently performing research, prototyping & testing new 28-135mm F4 L IS; less wide angle and more telephoto. Engineering says it would require 2 extra LD glass elements; shifting price to an additional $800 CAD of the original 28-135mm MSRP. such a lens would cost and estimated $1549 MSRP. It is also Canons next generation Image Stabilization will be released; called “IS2″, where the two additional long magnets are present, where larger float distance of separation between groups; yielding up to now 5 stops of effective stabilization; both in longitudinal and lateral vibrations will be dampened. IS2 will consume approximately 20% battery power.

Mount: EF
Focal length 28 – 135 mm IS2 II
Maximum aperture F4.0 w/ IS
Minimum aperture F22
Lens construction 21 elements in 14 groups
Diaphragm blades 8
Image stabilizer 4-stops tested AF actuator Ring USM (full-time manual focus built-in)
Filter diameter 82 mm
Dimensions (dia x len) 88.5 x 112 mm
Weight 730g EST.

I looked (not very hard) for a link to the thread. Please post it in the forum for proper credit if you can find it.

Canon Rumour

If it did comeup, it will be a good upgrade to the 24-105mm f4L. Parting it with the 16-35 F2.8 II would be perfect for walkaround...

The 28-135IS now, is a damn good underated lens already .. ( just a bit too slow on the tele end)

If this lens is for real, I can't see the rationale behind it at all.

Given today's dSLRs, the focal length doesn't really make a lot of sense. A max wide angle of 28mm is absolutely useless to the crop body cameras, so no sensible person with crop bodies will buy this at all. For the FF users, 28-135mm is an extremely flexible range, but given how FF dSLR is pretty much limited to the premium market, FF owners would likely be purchasing / already have a 70-200mm and a 24-70mm / 24-105mm already, so they wouldn't buy this 28-135 lens either.

The old 28-135 IS was really a relic from the film days. It was an affordable, general purpose walk around lens designed for the 35mm silver halide days of old. Honestly speaking, I am surprised Canon still hasn't retired this old workhorse as she is well past her prime.

If it estimates to be $1500, I think it's targeting the FF users. Mid range L lens is always a 'short' to the Canon crops' lineup.

Weighing 730g is around the same as the 24-105... And, if the rim size is 82mm but the aperture is still 4, it maybe a waste... I don't expect it will exceed the 24-70mm tough, but should be close...

24-70mm is really not suitable for Rebel user, the center of gravity is close to the zoom ring which hurts the wrist quite a bit...

Again, it's another f/2.8L vs f/4L IS fight....

For FF user, I think I will have 16-35/28-135 instead of 24-70/70-200 for daily use. They can also be easily stored in a smaller camera bag and the weights are lighter. For tele, you can easily pick the 100-400 (No more frustrations choosing between 70-200 and 100-400 when upgrading)...

Anyway, I doubt about this lens too, as the 28-135IS and 24-105L are 2 good lens at low cost already.

new 24-70L II will make more sense, as that lens is many yr old now, (still good) but the Nikon/Sigma/Sony one are all good and newer.

28-135IS II will make sense too, the best all round zoom lens from the film time.. ^_^

if they have time, come out with a 24-70L IS 好過啦. Rebel user shouldn't use 24-70L anyways. 17-55 lighter, smaller and similar IQ at less $. 24-105L is more than enough on the tele end for a crop.

Anyways, just rumor.

A 28-135 f2.8 non-IS will be more attractive to me, haha!

It's 99.9% you will not see the Canon 24-70mm F2.8L IS in the upcoming 2 years...

Go 135 without IS, you must have a pair of very steady hand....

I think he cares about quality .. Tripod .. Sun .. Flash .. etc instead of IS ma ..

作者: Look4chrisng 時間: 2010-9-18 07:45

I doubt Canon would release a very expansive F4 lens. If you are shooting fullframe, you probably have changed the focus screen. It will be dark for that kind of viewfinder. F4 lens make sense for DX I think, but 28 is not widen enough.

If they come up with 135 F2 with IS, then we are talking.

An IS version of the 24-70 is waaaaaaaaaaay overdue. I know the lens still sells, but certainly Canon can make a windfall if a new IS version were introduced?

I think Canon will just make a 24-70 F2.8L II .. no IS ..

But who knows, just me ..

Yes, there are some review, showing the Nikon 24-70 is a sharper la.. bluh bluh bluh ..

But for last 1/2 century .. ( or longer ) Nikon lens are sharper in general ..

That might be just one of the reasons. But cuz most of my shooting subjects need me to use a relatively fast enough speed, so IS is not practical for me.

作者: Catpiano 時間: 2010-9-19 07:59

IS is good .. but not that important ..

Why 135L is rated so sky high? since it is damn sharp, vivid, smooth bokeh, fast, fast AF, plus SMALL and CHEAP ....

If added IS to it? it won't be as SMALL and CHEAP anymore ... and more or less, affect the OP.
