I have a Sigma 120-400mm APO DG HSM not the OS version and an considering selling it as I do not use it very often.

I have the 55-300mm (DA version) and was thinking about using that with a Pentax SMC 1.7 X AF Adapter.

Has anybody used this combination, and the pitfalls surrounding it.

Thanks
Colin
