Lens comparison

I would be interested to hear any comments, comparisons between the new Canon 24 - 70 f2.8 L USM
and the Canon 24 - 105 f4 L IS USM which appears to be cheaper
Both are L grade yet the 24 - 105 is noticeably cheaper WITH Is
Is it just the extra stop that makes the difference. What about image quality.

The digital picture reviews should be approached with a little caution as to when they were updated.
Personally I really rate my 24-105 but recently have began to wish for f2.8 rather than the image stabilising.
Don't get me wrong, the 24-105 has that bit more range which I find useful and for many handheld shots the IS is fine. Just wish it were 2.8 for those time when shooting with a wider aperture would be more useful. However, I can do without it so I am told!

I have a 24-70 2.8 and recently did some comparison shots at my local shop as I was toying with the idea of it being a more versatile lens on a 4 week trip to SA
My findings on the sharpness side 24-70 slightly better especially wide open. contrast on the 2.8 was also noticeably better so at the end of the day I won't be changing at the moment as 2.8 v 4 is a big advantage especially for weddings as IS doesn't stop motion (give option for higher shutter speed) I'll carry the extra lens for reach

The two lenses are different tools for different jobs.
The 24-70 is more expensive and heavier, but it 1 stop faster.
The 24-105 is cheaper, lighter and has IS, but is 1 stop slower. This lens also has the extra reach.
So think about the price, the weight (will you be carrying it around all day), and think about if the extra stop is important.
As you may have read - the 12-105 does suffer from vignetting at the wide end. It can be quite apparent especially at wide apertures, but nothing a touch of 'lens correction' in photoshop cannot fix.
Most reviews I have seen have suggested that optical performance - apart from the vignetting issue - is pretty even across both lenses.

Yes I read about the Vignetting but it seemed correctable. Hadn't read that it was only a problem on FF but that does make sense. I've actually gone for the 24 - 105. The reason being that I have a Sigma 18 - 50 and it doesn't give me the reach I want.
The reviews of the other two have all been very positive for both lenses. I can hang on to the 18 - 50 for a bit to see how I get on with the 105 and keep it for the f.28 if I need it and if i find I'm not using it that much, sell it on.
