Has anyone had experience with this lens? The weight, size and speed are very appealing, but I have heard(not much) mixed reveiws on the DO technology. I am considering it as a replacement for my trusty old 600/f4 that I just sold since I don't want to lug around anything that large anymore. The 300/2.8 IS(had the non IS 8 years ago) is another option or I might just save the money and get the 100-400L zoom, but any feed back would be greatly appreciated.
I was considering the 100-400 L zoom myself but read quite a few comments from users on the internet indicating that the push pull design of the 100-400 zoom tends to act as a pump leading to problems with dust getting deposited on the sensors of the digital SLRs. If you use a digital body you might want to keep that in mind. I'm thinkin of getting a 300/4 IS L lens with a 1.4 TC. Anyone have experience with this combo?
I to am not comfortable with the push pull aspect of the 100-400(to used to the typical rotating type). I kept my 300mm IS and have both converters so I will just use this set up until I see where I'm going with my photography. It's light and versatile if not blazing fast.
I shot the migrating sandhill cranes this weekend at Jasper Pulaski with a couple of friends and we had the 100-400L and the 400L f5.6 and while I can appreciate the zoom, the 400L f5.6 is a very good, cheap option for a 400mm. It's very sharp and super light...too bad it doesn't have IS. I got some great shots with it.
