Lenses / Re: Canon EF 24-70 f/2.8L II

So, why no IS?
- If you are interested in a fast lens - f/2.8, than you are most likely shooting in low light.  Otherwise, you would purchase the 24-105 f/4 IS.
- If you hand-hold, then you need to bump up the shutter speed to compensate, and thereby negate some of the "low light" advantage of the fast aperture.
- This is not a sports lens due to the focal length, (for the most par) - where IS isn't really needed.
- The focal range is in the general purpose/walk-around range.

So, a general purpose, low light lens, not for sports, and used with a tripod?

Without IS, this becomes a very expensive, really sharp, general purpose lens - but not a low-light lens.

Am I missing something?

It depends what your taking pics of I spose, the shutter speed to stop most movement will generally be faster than the shutter speed to prevent camera shake so IS wouldnt improve its low light ability for such subjects.

For landscapes I'd guess Canon's feeling is that less serious users will probabley go with the 24-105 IS while more serious ones will be happy to use a tripod when needed to really exploit the sharpness to the full.

Compaired to the 17-55 the 24-70 isnt as long when you take the crop into account which cuts down the need for IS a bit and its also a good deal heavier/longer. Maybe not so much of a problem on a 1D but this new version looks like it will balance much better on a 5D to me with both being around the same weight.

As far as EF-S goes my guess would be that part of the reason for the 24mm and 28mm's being revamped is to potentially sell them to crop users as 40-45mm standards.  Add in IS aswell and you have the potental for a very compact and versatile setup on a Rebel.

I wouldnt get your hopes up for the Tamron given the negative effect IS had on the 17-50's image quality.

Personally I'd definately give up IS for IQ and size with a lens like this.

No EF-S... Good...

But 2.8? Naah. and really both 24 and 28.... somehow strange...

I wouldnt say that stange, the two existing 2.8 primes at those focal lenghts didnt look to be selling well at all compaired to say the 35mm f/2 or the 50mm f/1.4.

Adding IS and potentially focusing on better performance at 2.8 does also allow them to seperate the market from the L's.

Honestly it just looks like someone took a photo of that lens and photoshopped it. In fact that's exactaly what happened.

Oops, I believe its time for you to go away now.

Possible Martin. Though, if that is the reason...why wouldn't Canon make all their L-series glass white? :) Canon just announced their new version of the 24-70 f/2.8 (II) and it's.........black!

Supposedly, it's to reflect more light and reduce the internal temperature.  The reason it's used on the tele lenses is that the fluorite elements in those lenses are more sensitive to heat. Or so Canon has said...it could still just be a marketing ploy...

A bit of both I'd guess, probabley some small advanatge and now that Canon has "claimed" the white tele if Nikon were to use it they'd merely be confused as one by most people.

Proof the image is fake:

The lens is set at 24mm and is fully retracted. Canon lenses extend when they get wider, and retract when zoomed.

I don't see why thats "proof", the previous Canon lens retracted at 70mm but other similar designs from Sigma and Tamron havent.

Something about this lens is odd... It just doesn't look right for some reason. I can't exactly put my finger on it but something seems off.

Maybe it's the lack of writing around the red ring. Or, does it look too small to anyone else? (despite the 82mm filter threads (which is also really odd))

I thought something looked wrong too.  The font used for the labeling (24-70 Ultrasonic) is the same as a traditional EF lens, rather than L lenses.  Also missing is the red lettering indicating mm near the focus/distance window.

If you hold your hand over the red ring, this lens looks more like a standard EF than an L.

Compair it to the 100mm L macro released recently rather than L lenses from several years ago and it looks very similar in design to me.

If they could reduce the weight at the same time, I would be very, very happy, but I guess that is too much to ask.

Its hard to say for sure but as I said the impression I get is that its shorter than the Mk1, given that Nikon reduced the size of there 28-70 2.8 while still adding 4mm to the wide end I'd guess there may well be room for a size reduction.

Little strange that the 24-70 seems to have a 82mm filter ring  :o

I wouldnt say that strange, the 16-35 2.8 went up from 77mm to 82mm in the mk2 didnt it? might be due to the wider front element but that pic looks a little shorter to me, looks like the lens is retracted at 24mm rather than 70mm aswell.

It's very strange that 28mm and 24mm wide angel prime lenses have IS, any idea??

I wouldnt say that strange, on FF those are focal lenghts where many people are going to be stopping down for landscapes plus there both good potential general purpose lenses for a crop.

My guess would be that if we see anymore Canon maybe viewing the "X brand" as a way of focusing attension away from pure resolution. ISO performance and pixel quality are afterall the main selling points of the 1DX and the G1X over previous models and if rumours are correct the new 5D may have that advanatge over the D800, even the new 7D has often been rumoured to be sticking to 18 megapixels.

To some extent I'd guess Canon focus more on these areas simpley because their the areas FF DSLR's are most well suited for hence they are the larger market. Ultimately MF will always provide the better studio/landscape IQ while Leica will provide the best compact prime lenses.

It seems more likely to me that if Canon went with a range of "fast X2 zooms" the target marfket would be more similar to the higher end EF-S lenses.

That 55-110 f/2 patent we saw recently is the first thing that springs to mind, seems likely that might be for a potential EF-S lens so perhaps it could be added to with a say 25-55 f/2 zoom aswell? would be a good way of potentially countering crop sensors disadvanatges in DOF and low light shooting in a similar way to those Oly f/2 zooms tried to.

I could well see Canon looking to launch the 5D mk3/X with new versions of the 24-70, 35L and another quality lens(maybe a new UWA zoom? 17-40 mk2? 14-24?) to try and steal more of Nikon's thunder.

That said I'v thought for awhile that some form of medium format mirrorless might be worth them exploring. The benefits just seem more obvious than ASPC or FF to me, greater size savings both on the body and the lenses which will tend to be more in the wide/normal range that benefit from the reduced flange distance and less of a disadvanatge in AF performance since MF has never offered high performance there. I'd guess the potential for cost saving would be higher aswell given that your getting rid of a much larger OVF/Mirror.
