Looking at adding an intermediate zoom lens. Will have 500mmF4 as main telephoto lens
Want to replace a 70-200f4 which i rarely used, and can't see paying the extra $$ for the f2.8 version which would almost always have a tele-convertor on it
How does the newer 70-300 f/4-5.6L IS compare to the 100-400 f/4-5.6 L IS?
Any comments/other suggestions or personal experience would be appreciated
Thanks
PH
