It should be on Canon obsolete list
on September 14, 2017
This lens has been around many years and probably owned by many others due to its price and zoom range. But, I regret this purchase because it performance just could not be satisfied for todays technology. If you use it on tripod all the time, it maybe OK for you. However, IS on this 70-300 zoom lens just not good enough to hold by hand shooting 300mm subjects with good results. The IQ without tripod just not sharp enough for me at 300mm FL. And, 70mm size IQ on this is known just OK(not great). I also had to redo FMA often for this lens on my 6D to keep it in focus. Canon has new line of 70-300mm and should put this one on their obsolete list. Well, what I get on IQ and IS are what I paid for. Well, I am going to skip 70-300L and straight to 100-400L.
