Kenko TELEPLUS HD 1.4x for Canon EF Reviews
Works Well

Used this with a 6ti and a 55-250mm IS lens The additional zoom is nice, image quality seems ok, loss of 1 stop is not a problem by day. Auto focus is a little bit sluggish with the teleconverter, but it still functioned acceptably. Iâm happy with the purchase until I can afford a longer lens.
Excellent !

Kenko TELEPLUS HD DGX 1.4x Teleconverter for Canon EF/EF-S Lenses I got this recently. It effectively turns my EF S 55 - 250 canon lens into a 500 telephoto. Autofocus and stabilization work quite well. I am quite pleased.

Has anyone used this product successfully with a Canon 5D Mk IV body and Canon 70-300 F4-5.6L lens?
The lens would not have auto focus compatibility. You could use it in manual if you wanted to.

Yes, the Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for Canon EF and the Kenko TELEPLUS HD DGX 1.4x Teleconverter for Canon EF/EF-S Lenses would be compatible for use on the Canon EOS 77D DSLR Camera.

Will this works with the "Canon EF 75-300mm f/4-5.6 III Lens"?
The Kenko TELEPLUS HD DGX 1.4x Teleconverter for Canon EF/EF-S Lenses technically fit onto a Canon EF 75-300mm f/4-5.6 III Lens.
But it will not autofocus on some cameras and not well on others.

Can anyone confirm if this teleconverter does or does not work specifically with the Canon EF 70-300mm f/4-5.6 is II USM lens and the EF-M adapter on the M50 camera?
I've tested both the 1.4 and 2.0 Kenko TELEPLUS models and neither works with the Canon EOS M50 (mark 1), the Canon EF-M Lens Adapter and the Canon EF 70-300mm f/4-5.6 IS II USM Lens. As with other tested teleconverters, there is no power supplied to the lens (the LCD does not display) and the camera also displays a blank screen (no menus or anything).

Will this teleconverter work with CANON EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens on an EOS M50 Mark II Camera? Thank You...
Kenko TELEPLUS HD DGX 1.4x Teleconverter for Canon EF/EF-S Lenses will work with M50II camera and CANON EF-S 55-250mm f/4-5.6 IS STM telephoto zoom lens if you also get this adapter: https://www.bhphotovideo.com/c/product/883406-REG/Canon_6098b002_EF_M_Lens_Adapter_Kit.html Autofocus will be slow and may not work in low light situations since the aperture will be narrower
