Excerpt: I read a lot about the loud noise of the IS however, to be honest with you, it doesn't bother it, it just reminds me that it's on and working. Other than not being a true hand held lens to work with, even with the IS, I was a little disappointed with the image quality.
Pros: Durable, Nice Bokeh, Rugged, Strong Construction
Excerpt: Before I get into the details, I want to note that other reviewers (such as photozone.de) have reported on significant differences between samples and likely this is what I saw. I own the 200mm F/2.8 L and 400mm F/5.6 L and wanted something in between and with IS.
Pros: Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Summary: I found my copy of this lens unacceptable...Soft wide open. The imaging stabilizing was very clunky as well (IS) -- I use to use these lenses back when I was shooting news and they were always decent....this one was sent back...
Excerpt: Bought this to replace 400mm f/5.6. Wanted IS and f/4. Not really that impressed. IS seems just OK and I get sharper pics with 400mm f/5.6. Have to correct for abertations in Lightroom. I think of this as the poormans's 300mm.
Conclusion: I recently sold my 2011 300mm f4 IS lens after about six months of ownership. It was the perfect size and weight for a 300mm prime, and the short minimum focus distance was ideal for a variety of subjects. It had an excellent sliding lens hood and a nice soft case was supplied at no additional cost.
Conclusion: I've owned three of these over the years looking for the lens some people say they have. These lenses have been a disappointment to me in terms of pure sharpness and contrast compared with my old EF 300 2.8L.
Pros: Superior build quality, Fast auto-focus, dual mode is, relatively small and light
Excerpt: This lens causes the my 20D to hang up during shooting. Auto-focus ceases to work and the camera stops functioning. The only way to correct the situation is to remove the battery and re-insert. This problem only occurs with the 300 L; all other canon lenses work fine with the 20D.
