Just want to ask everyone if Canon would ever release the 24-70 IS version. I've read in some sites that they're going to release the IS version this year. Now, I don't know how reliable their information but it would be nice for the 24-70 to have an IS. Having a hard time at the moment whether to go for 24-105 or 24-70.I like the IS because it really helps counter camera shake and probably for low light at f4but the f2.8 is very tempting. Any thoughts guys? I shoot indoors and outdoors...thanks! IF EVER there will be a 24-70 f2.8 IS version, for sure I'll get that one.
