This tele extender can be used with fixed focal length lenses 135mm and longer (except the 135mm f/2.8 Softfocus lens), and the EF 70-200 f/2.8L, 70-200 f/2.8L IS, 70-200 f/4.0L, and 100-400 f/4.5-5.6L IS zoom lenses. Superb optically, it preserves the image quality of the lens it's mounted to and multiplies its focal length 1.4x. I had a 1.4X on my EF 100-400mm and was 100% completely satisfied with the image quality, I never took the extender off that lens. Another bonus buying the 400mm f/2.8 over the 600mm f/4 would also be carrying around a smaller and lighter lens. 4.1: 4.1: PowerShot G1 X Mark II ** See: Limitations with Canon Dual Pixel raw files in Camera Raw and Lightroom.

The 100-500L works amazingly well with the RF 1.4x converter. I was never a huge fan of the EF converters, and I preferred not to use them unless it was necessary. However, the RF converters have completely reversed my previous thoughts. When I'm out shooting wildlife I'll have the 1.4x on more often then not.

Di II Lenses 18-270mm F/3.5-6.3 Di II VC PZD A good 1.4x teleconverter, when used with a Canon L 300mm f/2.8 or 300mm f/4, can outperform a good (but not great) 400mm telephoto such as the Sigma APO (not the APO macro version) lens. The 300 + 1.4 TC combination also roughly equals the performance of a 400mm Canon L f/5.6 lens. FF is of course more expensive, but the price differential Please see the lens and/or camera body manual for full compatibility information with the Extender RF1.4x. Warranty Info.
