I bought the Sigma 1.4 tc for my SIGMA 70-200mm f/2.8 II EX DG APO Macro HSM and it doesnt work at all,I knew it would be MF only but all the exposure F stop and shutter speed info just randomly flashes,Sigma UK says it doesnt work but I'm sure it did when I checked before I bought it.Is there any way to make it work that you know of?
What makes it doubly annoying is I have now lost my 300mm end as I sold my Tamron 70-300 macro yesterday.
Has anyone got any suggestions for a decent 300mm lens or failing that is there a tc I can use on my DA* 50-135mm?
Thanks for reading my long ramble.

The Sigma teleconverters will not work on HSM lenses .. LINK. The Tamron MC4 1.4x teleconverter will work on HSM and SDM, mine works fine on the 3 DA* lenses I have but they are very hard to get hold of now as they are no longer made.

If you want to sell the 1.4x Sigma PM me as I have a friend who has the older MKI 70-200mm and may be interested for the right price.
