Sigma zoom, with Canon ef1.4x mk2

[lammypaul]

Hello all.

Can anybody enlighten me to why, my Sigma 70-200 f2.8. ex dg hsm mk2 zoom will not allow me to mount it onto my Canon ef1.4x mk2 extender.

does this mean i am going to have to sell my canon one, and buy the sigma version. then again i really want to use the canon one as it produces great results on my Canon ef 300mm f2.8.

anyone got any ideas.

cheers paul....

Hi Paul
I wasn't aware that there would be a problem mounting on the extender.
Works perfectly the other way round: the 70-200 f4L works perfectly on the Sigma 1.4 extender.

I realise this doesn't actually help you a lot.

Ps, is the invitation for sunday still open?

I believe the front element on the canon extender protrudes quite a way? Does it hit the back element of the sigma lens?

I think this is the problem, the sigma TC doesn't protrude nearly as much, so doesn't cause issues the other way around, but for some reason Canon decided to be difficult!
