Which is better? Canon EF 100-400mm f/4.5-5.6L IS USM or 150-600mm Sigma/Tamron?

    Hello all,

    I have owned a Canon 100-400 Mk1 since 2008 and I think the years have finally gotten to it. I don't quite have the funds the splurge for the $2200 Mk2 but I can afford the $899 150-600mm Sigma and Tamron models. My question is- are either of these two lenses better than my old 100-400 Mk1 (in terms of image quality, sharpness, etc.)? I am trying to decide if it is better to just buy one of these lenses or keep my dusty old 100-400 and maybe get it serviced.

    Canon 1Ds, Canon EF 17-40mm f.4 L USM, Canon EF 28-135mm f/3.5-5.6 IS USM, Canon EF 28-80mm f/3.5-5.6 II, Canon EF 50mm f/1.8, Canon EF 75-300mm 1:4-5.6 III, Canon 20D, Canon EF-S 18-55mm f/3.5-5.6 II IS STM. Pentax K-3, Pentax K10D, and lots more Pentax gear.
    I have the Sigma 150-500 in Pentax K-mount and it is a fabulous and very well built lens. Unfortunately Sigma has discontinued making K-mount lenses in this range and I would have been interested in a 150-600. On the 7D you will get much longer reach with the 150-600 if that is what you were after. After my experience with the Sigma I would not hesitate buying another and, as you have said, they are far cheaper than the Canon branded lenses.

    Another vote for the Siggy 150-600. I have the Contemporary version for my 7D MkII and I am very happy with it.
