I did use the 75 with the CL. It gave good results. But I got fed up of guesstimating the framing, managed to pick up an 90 Elmar C for a low price, and sold on the 75 for a fair amount more. Yes, the Elmar is a stop slower, but it too gives fantastic results and is amazingly compact.
Only problem... it's front heavy. Slipped offf my shoulder last Saturday and now there's a nioe ding on the filter ring...
