Canon extenders

[Chris Hall]

I have been reading reviews and posts about the Canon Mk III 1.4x and 2x extenders. As a new DSLR user, I think I understand the basic advantages and disadvantages of these bits of kit. If I bought one, it would be mainly for wildlife shots. Which would be the better buy if I was only going for one of them? Thanks in advance for any advice forum members can give me.

Re: Canon extenders

I personally don't have either but from the people that I know who do have the extenders they all advise the 1.4, you only loose one f stop and a not so much IQ. The 1.4 is used by a lot of people on this forum.

Do check that they will fit your lens and also consider that on a slower lens you may also loose auto-focus depending on your camera.

Thanks Muscat. I would use it on a 7D with my 70-200 MkII f/2.8 lens.

Re: Canon extenders

I have both (mk II versions) but I use the 1.4x a lot more as I think it loses me less...

The 2xIII is good on the 70-200 2,8MkII. As long as you do not take liberties with poor light. It does slow the af down and I find that to be more of an issue for birds in flight etc. than iq issues.

The 1.4TC is an excellent addition to your lens line up, while the 2.0TC (mkiii) has good IQ the focus & focus tracking takes a hit

I did a review of the 2.0TC here:-

Re: Canon extenders

What lens are you thinking of using with an extender?

Re: Canon extenders

If you only have one, it has to be the 1.4x. You would barely notice any difference in quality. The 2x needs a bit more thought rehgarding when to use it and a lot more light to get the best from it.
