Jun 07, 2017 07:10 | #4 Not a challenger... I doubt the sigma will match the build, AF and focus speed.... also the Canon aperture IS faster. A7rIII | A7III | 12-24 F4 | 16-35 GM | 28-75 2.8 | 100-400 GM | 12mm 2.8 Fisheye | 35mm 2.8 | 85mm 1.8 | 35A | 85A | 200mm L F2 IS | MC-11

The default (100mm, wide open, 5DIV) looks to be advantage Sigma. Look at the other bodies, other apertures and other focal lengths. The sigma is a lot worse at the periphery, and show a lot more than the 100-400II. I'll keep my 100-400Lc, thank you.

It also has a faster aperture, so it's hard to make a direct comparison between the two. By itself, the Sigma offers the better deal at getting good IQ at half the price of the Canon. Canon 5D mk IV

Jun 07, 2017 12:56 | #10 dochollidayda wrote in post #18373121  That's incredible, 100mm Sigma seems sharper, 400mm Canon seems quite on par with Sigma, the difference is really miniscule. Sigma has a contender on their hands, now if this thing can focus as accurately as Canon, I think this can be a real winner. It'll be a real winner on the budget crowd.

Last year I opted for the Canon 400mm over the Canon 100-400 because it was a little lighter and a lot cheaper. I don't need IS for BIF but sometimes wish I could zoom out a bit. I figure I could sell my 400mm and get the Sigma 100-400 for little to no money out of pocket. Hmmmmm. Canon R5 - Canon RF24-105L F4, Canon 40mm, Canon 70-200L F4 (non-IS), Canon 100-400ii, 1.4xiii

"wow....the Canon 100-400 mark II has a new challenger...." here we go again. lets talk six months to a year after the lens has been marketed. Overall it doesn't really give up anything to the Canon when shooting static high contrast subjects like test charts which is very impressive for a lens costing 40% as much. You would be hard pressed to tell which real life shot was taken with each lens.
