This sort of non-recommended functionality is pretty much impossible to comment on because there are too many permutations. In particular, the 70D and 7D come up in conversation quite often when used with Kenko extenders, or by taping over the contacts of a Canon extender so the camera isn’t aware exactly what is attached to it. I’m aware that in some cases, it’s possible to trick some older cameras into providing some sort of basic AF with f/8 lens combinations. If your 1D X doesn’t appear to be delivering AF at f/8, please check your firmware! “Tricking” Cameras With 3rd Party Extenders

The 1D X also launched without the ability to AF at f/8, but this was quickly addressed with a firmware update in October 2012 to Version 1.1.1. Check that firmware number in the menu system! Special Note About the 1D X This is especially possible if you purchased a second-hand camera. If you have a 5D Mark III that does not appear to be working for AF at f/8, perhaps you have not got the firmware up to date. This ability was added in a firmware update in April 2013, when the firmware was bumped up to V 1.2.1. When this camera was first launched, it did not provide AF at f/8.

If you have a Canon mirrorless camera, please consult your manual for the time being. Note that at this time, this article is only referring to Canon DSLRs and does not cover Canon mirrorless cameras. If you don’t see your DSLR camera listed in the table, it does NOT deliver any kind of autofocus with an f/8 max aperture combination. Canon 500mm f/4 L IS II + 2X Extender -> f/8.If you are a bit rusty on your f-stops, then you can refer to my f-stop chart in order to count either 1 or 2 stops up the chart from where your lens is. For more information on extenders, and the math behind this increase, you can read my ultimate guide to extenders and teleconverters. Next you need to know that that a 1.4x extender will increase the max aperture by 1-stop, and a 2x extender will increase the max aperture by 2-stops. This will be written on the lens, and in the specifications. To find out the maximum aperture of your lens+extender combination, you first need to know the maximum aperture of the lens in its native form.

This last part has become a little more complex in recent years because there are now some newer lenses that deliver such improved AF performance, that they allow more AF points to be used at f/8 than some older lenses. The table below will tell you whether any sort of AF is possible with your camera at f/8, but it will also try to provide up-to-date notes on which AF points work.

Some cameras will only allow the AF to work with a central AF point, and some will allow AF with the full gamut of AF points. Every year Canon is expanding the capabilities of their AF systems and the result is that more and more cameras do feature AF at f/8, but to varying degrees. Whether a camera will autofocus with an f/8 max aperture actually doesn’t tell the whole story these days. In the future, I’ll also create a similar resource to tackle other relevant manufacturers such as Nikon. It’s an often misunderstood subject in itself, but it also continuously raises questions about which cameras will still provide AF when used with a lens+extender combination that delivers a max aperture of f/8.įor now, I’m providing this information for Canon lenses because the majority of my lens and camera reviews in the past have been about Canon gear. The subject of autofocus (AF) at an f/8 maximum aperture is something that often comes up in my writings about cameras, lenses and telephoto lens techniques for subjects like sport and wildlife.
