Hi, Appreciate being able to join this forum. I was wondering if anyone has owned and compared several EF 100 or other macro lens or even the RF version and noticed much difference in the versions on this macro lens. After reading DXOMark it seems really only the IBIS is improved. I am using the EF 2002 version on an APSC M50 and even with long exposures at f32 the depth of field at full magnification reminds me of a microscope DOF. I see all these nice insect images online and beginning to believe they are stacked in photoshop taken at several focal points. That, or I need another lens. I am attempting to get as close as possible to subject, so perhaps I should back up and crop? Any input would be appreciated. Thanks.
