disneyry Posted February 3, 2006 Share Posted February 3, 2006 Has anyone done a comparison between the 70-200 f/2.8 IS with a 2x converter and the 100-400 being shot at 400mm? Does anyone have any first-hand experience with these combinations? Thanks in advance. Link to comment Share on other sites More sharing options...

michael_schrag2 Posted February 3, 2006 Share Posted February 3, 2006 Try photozone http://www.photozone.de/8Reviews/index.html. If I recall correctly the review for this lens also has results with a TC added. Link to comment Share on other sites More sharing options...

ky2 Posted February 4, 2006 Share Posted February 4, 2006 Ryan, regardless of performance issues (the 100-400 is better), would you really want to invest more and carry much more? sometimes you don't need the best perceivable performance (we'd all be carrying primes then). I'm not a TC-guy, but some-times it's a sensible solution. Link to comment Share on other sites More sharing options...
marknagel Posted February 5, 2006 Share Posted February 5, 2006 Ryan I have both. I bought the 70-200IS first and then the 100-400L. Hands down I would choose the 70-200is over the 100-400. BUT, if you are only interested in the long end, the 100-400 is sharper at 280mm (70-200+1.4tc) and way sharper at 400mm (70-200+2xtc). Either way you con't go wrong. Both are great lenses and if you are comparing them to a hyper zoom or cheaper lens, eithier combo would be better. I just got back from Puerto Vallarta where last year I took some shots of my wife swimming with the dolphins with a Tamron 28-300 XRDI, and this year took shots of a friend doing the same from the exact same location (20-40 yards away) with the 100-400L, what a differnce. Its the difference between making out the faces at that distance and making out the eye colors. Mark Link to comment Share on other sites More sharing options...
