So I just bought the Canon 70-200mm f2.8L IS and it got delivered on Friday. I've been playing with it during the weekend and it's REALLY sweet. I have that lens covering my long shooting needs, and an ef-s 10-22mm f3.4-4.5 USM covering the wide end, both of which I'm really happy with. For the mid-range, I have a 28-135mm f3.5-5.6 IS USM. It's a pretty good lens considering the price. $400 for a pretty wide zoom range with IS and USM. It's also one of the sharpest lenses I own. The problem is that it's a little slow for my needs (wedding photography, which often involves lots of photos of people in low light situations). I want to upgrade to the Canon 24-70mm f2.8L to take over my mid-range shooting needs. I'm attracted to it because it has a fast max aperture and L build quality. However, I'm bothered by the lack of IS, which even my $400 28-135 has. I've looked at the Canon 24-105mm f4L IS, which does have the IS. But the aperture is so slow that it's hardly an upgrade over what I already have. I really wish Canon would put IS in their 24-70mm f2.8L!!!! That would make my decision a no-brainer. I've heard rumors that Canon is working on just that. Does anyone have any insight into whether Canon is going to release such a lens any time soon? I don't want to spend $1200 on the current 24-70 with such a glaring deficiency if they are going to release a new model with IS any time soon. Thoughts?
