*AF works well. Works perfectly.

*I was using it with the Sigma 300mm F/2.8 EX DG HSM lens.

*As can be seen body was painted white by the previous owner. This does not affect the functionality of the tele converter. 

*I tried taking off the paint but did not go through with it fully. 

*Glass of  tele converter has no dust, scratch or fungus issues.

 

*Comes with both caps.
