The Canon extenders will not work with the EF-S lens which is why I have the Kenko 2x extender. The bumblebee was two cheap third party extenders stacked and wide open at F/16. I often use EF100-400mm f/4.5-5.6L IS II USM +2x III which autofocuses well on EOS R5. Sometimes I use 1.6x crop mode with the 2x extender VILTROX Auto Focus 2X Teleconverter Extender Converter for Canon EF Mount Super Telephoto Lens 135mm f/2L,200mm,300mm,400mm,600mm,70-200mm,100-400mm and DSLR Camera 5DII 80D 760D 7D,Black. 77. 1 offer from $159.99. Canon EF 1.4X III Telephoto Extenter for Canon Super Telephoto Lenses. 348. The Canon 1.4x lens extender extends the focal length of a lens by 40%, making (for example) a 200mm lens function as a 280mm lens. making them fully compatible with full-frame, APS-H and APS "Teleconverters are one of those things people buy when they first start in photography because they sound like a neat idea." So true. I would try the cropping route first. Because it is free if you have a simple post editor which most OS's come standard with or d/l one of the free ones. You will nWQt. There are two lenses that do work well with a 1.4x tel-con. Never the 2x however. The ef 70-200mm f2.8L and the ef 300mm f4l IS. The nice thing about the 300mil is it has the IQ to give up, but it becomes a 4200mm f5.6 lens with IS. Canon's fantastic and unique ef 400mm f5.6L does not have IS. So the converted 300mil is a good give and take. Anybody tried out the Canon EF 2x III Extender with the EF 70-200mm f/2.8L IS II USM? I have a Canon 5d Mark III w/ 24-105mm and 70-200mm lenses on the way, I'm wondering how well the extender works with them, especially the 70-200. I'm hoping that it'd work pretty well for airshows and wildlife.

EF Lens comparability for top FPS. Jul 22, 2020. So the R5 will offer a maximum of 12 FPS mechanical shutter & 20 FPS electronic shutter, however apparently this will vary on what EF lens & aperture etc is connected. I cannot see anywhere on the Canon website which states what EF lenses will get the top FPS and what other lenses are expected to The extenders have a front projection that goes into the rear of the lens. Most lenses have the rear element very close to the mount. One exception to to the compatibility list is the 70-300L zoom. As long as the lens is kept at 300mm the extender will fit. If the lens is zoomed shorter the lens can bump into the extender. 01-01-2014 02:01 PM - edited ‎01-01-2014 02:02 PM. As far as I know, Canon 2X Extenders (teleconverters) cannot even be fitted to any of the 70-300mm lenses. The Canon Extenders all have a protruding front element that prevents them from even being attached to quite a few lenses. They can be fitted to the 70-200mm zooms, as well as the prime
