Upload & Sell: On
i own a 300 2.8 non-IS mk2 and cannot part with it... i considered selling it at one point, to "upgrade" to an IS version, but couldnt pull the trigger on the price difference. hands down the sharpest lens i own wide open. it performs just as well with a 1.4x on it (f4). no noticeable difference in performance, and its just as sharp. its horrible with a 2x though.
ill upgrade my 70-200 before the 300.
it is heavy, and i dont hand hold it. monopod for me.
+1 I've had and sold a 300 2.8L non-IS twice, and both times bought another one, and have no plans to sell my current one. Great performance/price ratio, built like a tank, and very useful if you have a pair of TC's, I have the Canon vII's. I hear the V3's, especially the 2x is better, but to really see the difference you need a full frame camera, as I have a 7D, I plan to hold onto the vII version for now.
