Am trying to get 1.4x extender for my Sigma 150-600 contemporary lens (canon Mount), would like to use it for wildlife / bird photography.

Camera am using: 5D Mark III (placed order for R5 - waiting on it :))

Does 1.4x TC works well on this lens?

If So which one should i get Canon 1.4x or Sigma 1.4x

  1. Better get the Sigma, the lens is designed for it

  2. The 1.4 TC will make it a 840mm lens, but also a F/9 lens. So:

    • The AF will struggle, assuming it works at all, forget it for birds in flight (but then, aiming at birds in flight with a 840mm lens requires a lot of training)...
    • Even with decent IS, you don't want to get too long exposures (especially on a dashing sparrow), you need all the light you can and the TC is taking some.

So IMHO, the TC will soon return to your bag (I have one, but I don't use it for wildlife...).
