- great macro lensThis lens is amazing as a macro lens. I shoot with a Canon 100mm 2.8 macro also and love it, however I have to position too close to the subject To shoot macro with the 300mm, I have the ability to shoot from a little distance, and still get a fantastic shot. With the 300mm 2.8L, resuls are clear, crisp and he bokah is fantastic. Extension tubes are a must have to use this lens as a macro.
- Most of my photos aren't in focus with this lensI 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 far, its not even close. I did read on-line where other people were having similar issues with it and recommended using ONE SHOT AF versus AI SERVO (AI SERVI is what I have always used with my other lenses), so I tried it today just using ONE SHOT and did have a couple of photos that were sharp, but, 2 sharp photos out of 60, isn't very good, and the other 58 weren't even close to being sharp. I could have gotten some really nice Red Tail Hawk and Coopers Hawk photos today had I took my other lens. I don't know if I just got a bad lens or what, but, it looks like I will need to send it in for repairs.
- A bit of a disappointment for meI 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. I really wanted to like the 300mm f4, but at the end of the day image quality is all that really matters, and in this regard the lens was a disappointment for me. I use a 40D, and if I was careful to shoot stopped down to at least f5.6 this lens could produce pretty good images, but not significantly better than the 70-300 consumer (non-L) zoom stopped down to f8 that I used to own. I bought the 300mm f4 planning to use it with a 1.4x teleconverter, but this degraded the image noticeably, even stopped down to f8. In addition, the IS on the 300mm f4 was only good for one or two stops max with no tripod-sensing feature, and the AF was not consistently accurate and was too slow to follow birds in flight when using a 1.4x teleconverter. Downloading images at the end of a day shooting with the 300mm f4 was often frustrating – too many missed shots that were either slightly out of focus or simply too soft for my expectations.
- Still decidingI've shot with a 30D for about 7 years and recently switched to a 7D. All my digital SLR experience has been with these APS-C cameras. I purchased the 300mm IS f4L as a way to get a little more magnification than the 70-200mm IS f4L that I already had. With the APS-C format this lens performs similar to a 500mm (480mm), so it works well for bird and nature photography. I was hoping that the 'Prime' lens would out perform, or at least match, the great performance I experienced with my 70-200mm IS f4L. Although its performance can sometimes be great, especially close-up, at longer distances it produces slightly soft images more often than I would prefer. More often than not, I find myself gravitating back to the 70-200mm for its "Rock Solid" performance, rather than risking unsure results from the 300mm. My best results with this lens have been insects and small widlife shot at it's extreme close range end (5 feet+). I've recently purchased a 7D to replace my 30D and I'm interested to see if the 7D's 'Microadustment' feature can save this lens from it's spotty performance.
