roger_shrader Posted March 28, 2002 Share Posted March 28, 2002 You will lose quite a bit of quality with the 70-200 and 2x option. Here is a good review of exactly what you mention. I hope this helps... <p> http://www.luminous-landscape.com/400v400.htm Link to comment Share on other sites More sharing options...
isaac sibson Posted March 28, 2002 Share Posted March 28, 2002 Whilst the luminous landscape test is with the old converter, I doubt there'll be a night-and-day difference between the two converters. If you want a 400mm lens, buy a 400mm lens, not a 200mm lens. <p> Since you already have the 100-400, keep it. It will be better as a 400mm lens than the 70-200 F2.8L IS + TC, and also, if you have an EOS 3, 1V or 1D, makes a usable (I've seen some great results) 560mm F8 with the 1.4X TC.

steve_dunn3 Posted March 28, 2002 Share Posted March 28, 2002 Yeah, what they said. As awesome as the 70-200 f/2.8L IS USM is, and as good as the new 2x is, if what you want is a 100-400, you're better off with the 100-400 and no TC. If you want the 70-200 IS lens to replace your 70-200 non-IS, I'd say that's a good call if you can afford it. But I can only see two reasons for replacing the 100-400 with the 70-200 IS + 2x: if you want the 70-200 IS but can't afford it other than by selling both of your existing lenses, or if the size/weight of having two big zooms to cart around is too much. <p> Of course, if you DO decide to replace either or both, feel free to ship the leftovers to me :-) Link to comment Share on other sites More sharing options...
lee_shively Posted March 30, 2002 Share Posted March 30, 2002 My non-IS 70-200 is pretty good with the new 2x but at 400mm it's not in the same ballpark as my 400/5.6L. It's a decent trade off to lighten the camera bag. I don't think it would be wise to ditch the 100-400 IS lens and depend on a 2x extender.

peter_phan3 Posted March 30, 2002 Share Posted March 30, 2002 What would you like to accomplish by replacing your existing 70-200/2.8 and 100-400L IS with the 70-200/2.8L IS+2TC? Link to comment Share on other sites More sharing options...
