I already have the version I of this lens and have been thinking about selling it and upgrading. Is it worth it? I also have a 1.4x III and use it to get close enough to 400 that I don't think I can justify getting the 400 as a second lens. I would also love to have the new 200-400 but the cost is just ridiculous although it would be perfect for me - I shoot a lot of field sports (soccer, football, baseball, lacrosse . . . ). So again anybody that has upgraded for the version I of this lens, was it worth it?
Hi Andy, if you can afford it, absolutely do it.
I was always impressed with the Version 1 300f/2.8, but the advantages of the Version 2 are immediate weight gain, this Lens is about as Hand Holdable (is that a word??) as the 70-200f/2.8 L II, it's amazing how they got this (and the 400V2/600v2) Lens so light. You will see an immediate gain in Focus snap on, this V2 focuses faster, I get a lot more In Focus shots now than I did with the V1 Lens, agreed, I'm now using the 5DMK III & 1Dx so some o0f the faster response etc perhaps go to the new Cameras, I used the Version 1 Lens with the 5DMK II & 1DMK IV.
I have the 200f/2, 300f/2.8 v2, 400f/2.8 v2 & 600f/4 v2, the 200-400f/4 I'll have hopefully by the end June this year, and the only Lens I intend then selling will be the 400f/2.8 v2, the 300 I'll likely die with, this without any doubt is the sharpest Lens I own. The 200f/2 is no slouch either, but it's not as fast as the 300 v2.
The 3 Lenses i have that I use the most & just love the Images that come from them, in order of Love, 300f/2.8 v2, 200f/2, 85 f/1.2 L II.
