Canon 400 5.6 With 1.4 Extender

By | 13/10/2022

I’m currently shooting in the Canadian Rockies once more and wildlife is all effectually me. Whilst I have my large Canon 200-400mm with me, I’ve mainly been shooting with the Canon 7D Marking 2 and the amazing Catechism 100-400 f/ L IS Ii. This combination get’s me to a 640mm equivalent field of view in a paw-holdable bundle. In the right low-cal, the image quality is as as good every bit the $12,000+ 200-400mm lens (my Canon 200-400mm review). Yeah, you read that right… permit’s take a expect.

I was curious what the operation of this lens would exist like with a 1.4x extender. This combination gives you an equivalent field of view to an 896mm lens, and a minimum f/8 aperture. When I offset tried this, and looked at the photos, my eyes popped out of my head! Even wide open up at f/8, this is a more than than useable combination. In fact, information technology’south sharper than my old Mk1 300mm f/2.8 IS with a 1.4x extender on it. These kinds of results have chop-chop made this lens an all-time favourite from Canon.

I know that a lot of people aren’t going to believe me when I say this this combination is this adept, so I’1000 including some images, with 100% crops. These images only have the default sharpening from Lightroom applied to them and they were all shot with the 7D Mark 2. Now, this camera is VERY proficient, merely it doesn’t resolve fine details similar a total frame photographic camera does. Had I taken these shots with my 5D, or a 1D, these would have been fifty-fifty sharper!

Because these were both taken handheld, at shut to 900mm out of a motorcar window, I call back this is astonishing functioning! Every Canon wild animals lensman should have this lens in their arsenal. Information technology is very rare that I say things similar that so definitively, but this is a truly outstanding lens. Of course to get great results, you must understand the best means to use an extender. This is a topic that has been covered extensively in my ultimate guide to extenders/teleconverters.

I wonder how the new RF mount 100-500mm performs…

Catechism 100-400 Two + 1.4x Extender – Instance 2

Will Your Photographic camera AF at f/eight?

Not sure if yous will be able to maintain AF with your photographic camera, and the combination of the 100-400 + extender? Since this is a question that was asked so ofttimes in the comments, I accept created a resournce to listing all DSLR cameras that will maintain AF with a lens+extender combination that delivers a max discontinuity of f/viii.
