bobatkins Posted February 24, 1999 Share Posted February 24, 1999 Super UD glass has been used for a while. I think the 400/5.6Lwas the first lens to use it, and that lens must have been aroundfor at least 3 or 4 years now. <p> I have no idea what Canon will do and when they will do it! <p> The 100-400L IS is a great lens if you want and need a zoom andyou plan to take advantage of the ISfunction. I have not used one, so can't comment more than that.FWIW, I'm personally sticking with a 300/4L (+1.4x TC) to cover thelong end of that range. From what I've heard, it's a decent performer,but no "miracle" lens. The primes (even with TCs) are still sharper.I'll repeat I haven't used one, so I can't comment from my owndirect experience.
