Good extender for not a lot of money.
For the Mk1 version. Used on my Sigma 150-600 sport is produces very acceptable image quality, with only a very hind of softness added. Auto focus works OK too but a bit slow and need lots of light.
Will not work on a lot of the lenses such as EFS range. Won't AF on the 100-400L.

Ok on cameras other than Canon digital
0 of 1 found this helpful Be warned, this lens WILL NOT WORK on CANON DSLR's.
You will crash the camera if you attempt to shut the aperture down.
Tested on a 20D 40D and a 450D.
Same goes for a Sigma 400mm I own.

Very high quality PCB.

Please do the preamp board as well!
