Lensrentals.com Puts the EF 24-105mm f/4L IS II Through Testing

By Canon Rumors | November 30, 2016 | Canon Reviews

Roger at Lensrentals.com has completed his MTF testing of the brand new Canon EF 24-105mm f/4L IS II.

From Roger

As always, I remind you that this has been an MTF test; it was only an MTF test. Had this been an actual photograph you would have been instructed that all differences were simply because of poor technique.

But on the basis of MTF, the 24-105 f/4 IS II is a decent lens, but not a spectacular upgrade. Would I upgrade my old 24-105 f/4 IS? Nope. If I was in the market would I buy one? Well, I’d wait for the price to come down or for it to be available as a kit lens with a new camera. One other thing to consider is that the new 24-105mm is significantly larger than the original version, and for some people, that’s going to be a negative for a walk-around lens.

We were hoping that Canon would continue their run of big improvement over previous iterations, such as the EF 16-35mm f/2.8L III and the EF 100-400mm f/4.5-5.6L IS II. However, at the price point of the EF 24-105mm f/4L IS II, we’re not surprised to see only moderate improvement.

We haven’t seen anything that shows increases coming to other parts of the world, but we’ll let you know if we do.

*note I incorrectly named the EF 70-300 f/4-5.6L IS as the lens pertaining to the issue, when in fact it is the brand new EF 70-300mm f/4-5.6 IS II USM lens. Sorry about that.

Canon appears to have updated every legacy DSLR that has aberration correction to fix an issue with the EF 70-300mm f/4-5.6 IS II USM.

  1. Corrects a phenomenon in which when using the camera with the EF 70-300mm f/4-5.6 IS II USM lens, even if lens aberration correction is set to “Enable”, correction will not be applied.

The following DSLRs have available firmware updates.

Happy firmware updating!
