Canon EF Extender 2,0x III

A great improvement on my previous extender, as has not lost the auto focus facilities, unlike the previous extender, so becomes a pleasure to use.

Item received well packed and on time, I would use Castle Cameras again.

I took up bird photography over a year ago by purchasing the Canon EOS 90D camera along with the Canon EF 100-400 mm f4.5-5.6 L IS II USM lens. During this time I have achieved excellent results, yet I wanted to get even closer to the birds and other wildlife. I took the plunge. I have not experienced any issues with the Mark III extender myself and would highly recommend it.

I read lots of reviews to confirm that the Canon EF Mark III 1.4x Extender would work with my EOS 5D mk 3 and my new Canon 100 - 400 lens . So I was disappointed when the autofocus showed absolutely no sign of working. I read in another review that the camera firmware could be updated to improve autofocus when using extenders. My camera was bought in July 2013 and had firmware version1:1:3. I downloaded firmware ver:1:3:6 from Canon and now the autofocus appears to work.

Ich habe den Canon Extender EF 2x III gekauft, bin aber nicht zufrieden, da der AF nicht funktioniert. Nach Angaben Canon ist nur MF möglich. Kamera EOS 6D Mark ll Objektiv 100-400 L IS ll UMS
