Curious about this and can't find an answer anywhere...I have the Sigma 120-300 OS (non sport) and love it apart from the POS bayonet hood. The newer sport versions seem to have a hood with a thumbscrew similar to my old Canon 300. Can that hood be used on the non-sport version as a substitute for the bayonet?
...if you want me to take some measurements or something on mine let me know...i have no clue how to determine if it would work or not though
