I have the original 1.4 V1 extender and Im thinking of upgrading to the V3 but can't find any information on the differences.
Is there a big enough difference or should I just stick with what I have.
Im currently shooting with the 7D markll and thinking about getting the 100-400 ll.

All three Canon 1.4x teleconverters have similar optics. The 1.4x II added weather sealing and some new coatings. The Mk III has updated optics and new Flourine coating. I would only upgrade to a II or III if you have lots of money as most people don't see a noticeable difference in image quality.

After having used the I's and II's for quite a few years, I immediately noticed improvements in CA control and other subtleties with the III's. To me the differences are desirable enough to upgrade, but how particular you are, the bodies/lenses you use, the subjects you shoot and under what conditions are the determining factors as to whether to upgrade or not.


Canon : EOS R : 5DIV : 5DS R : 5DIII : 7DII : 40 2.8 : 50 1.4 : 35L : 85L : 100L IS Macro : 135L : 16-35L II : RF-24-105L IS : 70-200L II : 100-400L IS II : 1.4x & 2x TC III : 600EX-RT : 580EX : 430EX : G1XII : Markins Q10 & Q3T : Jobu Gimbal : Manfrotto Underware : etc...

The Mark III versions are also said to have CPU capacity to make them a better match for newer lenses, like the EF 300 mm f/2.8L IS II USM and similar. Thius that should guarantee the best AF performance from these lenses, when combined with a converter.

But I don't know if you'll notice the difference. I don't have any older converter than the Mark III versions, so I can't compare.
