My vote is the 300 f4 IS plus 1.4tc. It really isn\'t as heavy as most make it to be especially with the grip, which seems to better balance the weight. I have this lens and it take very sharp pictures with the 1.4 tc and focuses fast but then again I have no experience with lots of lens. When the light is bad or not the best anyway and if I am able to get pretty close to the subject, I removed the 1.4tc so that I can capture more light at f4. Plus you can turn off the IS so you get the best of both worlds. This gives you 400 or more reach. But from what I see it is always about good light or being on the right side of the light to capture nice shots. My keeper rate is getting better the more I go out and shoot with this lens. So unless I come across a deal that I can\'t refuse I will continue to work and get better with the 300 f4 IS lens.
I tried the Sigma 50-500mm non IS and I wouldn\'t waste my time and/or money. I could not get any decent shots handheld with that heavy monster. You\'d definitely have to use a tripod or monopod in my opinion.
