Excerpt: So, I have had 2 different 70/200f4 IS L Lens and felt like i was just not getting that L Lens clarity, So they where returned and i ordered this and was weary about weather i was going to be happy with a lens that i can not zoom in or out with.
Excerpt: I bought this to supplement my 70-200mm f/2.8 L for a somewhat greater reach in appropriate situations. I have had excellent results so far with both still and moving subjects.
I tried moving subjects (Greater Sandhill Cranes) yesterday for the first time - handheld.
Excerpt: I bought this lens a few days ago, and have to say that I am highly disappointed with it. On my first day using it, None of the 70 or so photos that I took were in focus. I have been using the 100-400mm IS mkII since it came out, and was expecting this lens to be at least as sharp as it, but, so...
Excerpt: I needed a ~300mm telephoto lens for some well-lit indoor and outdoor events. The Canon 300/4 is just fast enough to be able to handle my indoor requirements, and of course works wonderfully outdoors. (Going to f5.6, like on some 70-300 zooms, would be insufficient for my indoor application.
Excerpt: This lens is a real bargain. It is a serious professional lens, but since it has been in Canon's line-up for more than a decade, it can be bought for a really nice price. The AF is actually very quiet. Many people saying that AF is loud simply mistook the noise of the old IS system for the AF noise.
Summary: Consider the following: The 300mm f4 is ~$1400 and weighs 1.2kg, the 300mm f2.8 IS II costs $6,600 and weighs 2.4kg. With the money saved one can buy a few other lenses or a good full frame body while ALSO saving the back aches associated with lugging 2.4kg of f2.8 glass around on all day...
Pros: This is an impressive lens which was released 1997 and is still in production because it is inexpensive, lightweight and only one stop slower than the f2.8 Canon lenses lenses at ~1/5th the cost
Cons: Photos produced with the 1.4 MK III extender look terrible in large formats/prints but acceptable at smaller formats (about the size of a sheet of paper). Just buy the 400mm instead of cheaping out on an extender and your photos will be professional quality.
