Apr 23, 2014. #1. I have wanted to try the new Tamron 150-600 with a 2X but have struck out. When I got the lens I was hoping my Canon 2X would work. It didn't since the black inner ring was to long. Then I took the lens to the local Camera shop and tried a Kenko.

And that will only be with several of the center AF points. (The 5DIII is the only non-1D series camera to offer this, all others require f5.6 or larger.) As mentioned, putting a 2X (that "costs" two stops of light) on the 100-400mm f4.5-5.6 makes that into an effective 200-800mm f9-f11 lens. So when that registers with the camera, AF is turned In reply to CP1005 • May 8, 2017. I have shot the 5D Mk 4 with the Sigma 50-500mm, the Sigma 150-600mm Contemporary, original Tamron 150-600mm and the Tamron 150-600mm G2. I settled on the G2 and have been very happy with the results. GriffinClubMerv's gear list:

The SP 150-600mm f/5-6.3 Di VC USD G2 is available in Canon EF Nikon F mounts, and the SP 150-600mm f/5-6.3 Di USD G2, without VC, is available for Sony A mount. An optional lens case with zipper closure is also being released and will work with both the SP 150-600mm G2 and original SP 150-600mm. The 1.4x 2x Teleconverters will be available in Agree with the others that the RF 1.4x is an excellent addition to the bag. It's very sharp and fast-focusing, even more capable than the 1.4x iii (on the 100-400ii). I've hardly had mine off the RF 100-500, it's that good (I do mostly birding).
