Read that the 24-70 F2.8L extends while zooming, anyone got a picture on how long the lens extend to the max?

I seen a pic of the 24-70 f2.8L extends.
wander what's the rational of the extension while at the wide end? to cater for the hood?... tat's a bit rubbish..
The length of the barrel (even non extended), the weight and the overall bulk of this lens is what made me sell my copy off. My good ol Tamron 24-135 did just as good a job.
So is that one of the main reason ppl is letting go of this great lens?...
I have not got hold of this lens yet... so was wandering those who have / had tis lens... what is the main reason hindering you from using this lens frequently?

The weight and size. And the slow f2.8 (compared to primes).
'To cater for the hood' is not rubbish - it is in fact ingenious. Else the 70mm end will have to live with a short 24mm hood.

Ross, if you read the Fred Miranda article carefully, you'll see the reason for this is quite compelling. How do you design a fixed hood for a wide to tele zoom trying to balance the need for flare control and minimising vignetting, not an easy task I would imagine!

The full extension at 24mm is around 6 to 8cm, can't remember exactly. ot significantly very long or would it be an issue.
The main thing about this lens is that it is very heavy. You've got to carry it around to believe it. Ideal range and speed for walkaround, but not ideal weight. But picture quality and colour is fantastic.
used one to cover an event... good lens, pretty useful range on 1.3x crop body but the day after my left arm aching (almost as heavy as 70-200 IS) :cry:
this monster lens about 90g less than a kilo!
i work with pros and some do not use the hood at all.
with the hood on, it looks like a monster.

This is one heck of a lens used by the most discerning digital photographers (usually professional) who does not want to be hassled with changing lenses often but yet want a fast f/2.8. Weight shouldn't be an issue to them if important shots matter a lot.
I believe if you shoot with a high mega pixel cam such as the 1D MkII or 1Ds, you can tell the diff in image quality between the 24-70 and other consumer or 3rd party zooms. Do think about distortion control too.

I think the theory is that with high resolution sensors you begin to discern the resolution limits of even the best lenses. I assure you though, L quality is obvious even on a 3MP D30, contrast and colour being the other important factors.RossChang said:
Sharpness ain't everything... Sigma, Tokina and all these can give u razor sharpness.
L's for the f-stop, the colour, the texture that it can render...but frankly, with digital, all these can be achieved in Post-production
