? 24-70 f2.8 vs 24-105 f4

Hi, I am brand new to this forum but have a question already.

I currently have the 24-70 f2.8 in my arsenal and really adore this lens. It is a great street zoom for me among other things. I have been hearing wonderful things about the 24-105 f4. I like the fact that it has more focal length but wonder about its comparison of the other f2.8 to this f4. If anyone has any first hand expereince info on this lens can you please let me know regarding how you like it and the sharpness of it. TIA, Linda

There are several similar posts over the last few weeks. Try a search. Personally, I'd prefer the f4 IS L but if you already have the 2.8 and are happy with it then I wouldn't see it as an upgrade worth doing unless you want IS and the extra length. Welcome BTW.

Depends on what you're trying to do. If you want to be able to handhold slower shutter speeds, then get the f/4L IS. If you want to be able to stop action and get higher shutter speeds, stick with the 2.8. A fast ap. will beat out IS anyday for me.

Truly, they need to make a 24-105mm IS f/2.8....that is the solution

Mmm...I can see that costing a solid $1800.

that would be awesome.

Hey Linda how much use does the 28-135 IS get? I would assume the 24-105mm would be used for the same subjects/material.

Else seeing that you are using a 20D, the 17-85 IS may provide the image bump over the 28-135 IS and still give you a light general use lens with less of a hurt on the old wallet.

and about the same size and weight as the 70-200L f-2.8 IS.

the 24-105L was designed to be a lighter, smaller lens in the same category as the 17-40L f4 and 70-200L f4.

i hardly ever use f2.8 on my mid-range zoom and i have other lenses for low light stuff. i'll gladly sacrifice the extra stop to have the IS, lighter weight, and added range.

and i suspect from what i see many others feel the same way.

I would still choose a lens with wide aperture if I can afford. The 24-70mm is really big and heavy, but it's a matter of habit and personal feeling on handling the lens. In image quality the two lenses are close and guaranteed. However there's not enough justification for me to get IS with much price added.

But still overpriced.. like all their f4's when they come out(ie 17-40)
