There is also the case that the hood is probably designed for full frame, and is therefore less effective than it might be on APS. I ran into this with the horrible hood on my FA31. What I ended up doing was stacking a bunch of filter size reducing rings to emulate the wonderfully effective hood on the DA40. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
