Hi Kyprianos, and welcome to the TDP forums!

Of course, Canon makes the 70-200mm series in both f/4 and f/2.8, with and without IS at both apertures. Given that, I would think that Canon certainly could release a 24-70mm f/2.8L IS at a price point higher than the current lens, and keep the non-IS version in the lineup. I really like my EF 24-105mm f/4<span style="color: #ff0000;"]L IS, and I appreciate the advantages of IS even at wide focal lengths. Many times, though, I'd like the extra stop of light, so I've considered the 24-70mm f/2.8L, but haven't jumped on that yet. If they do release an IS version of the lens, I'd definitely buy it.

I doubt that. First off, I'm sure they'd keep the 24-105mm as the 5D series kit lens, so it would still sell a lot of copies. Second, you'd have a choice of f/4 lens with IS or f/2.8 lens without IS at an approximately similar price point (just like the current 70-200 f/4L IS and 70-200mm f/2.8L non-IS), and an f/2.8 lens with IS at a substantially higher price point (like the 70-200mm f/2.8L IS II). I'm not sure how they justified charging a 60% premium for IS on the 70-200/2.8 - but they did, and it still sells well (I bought one [] ). Given that, Canon may see an opportunity for a substantial profit. I hope they do, and take advantage of it! Bring on the 24-70mm f/2.8L IS!!
