We have Canon 550D cameras and wanted to get into some macro work. We have the kit lenses and find the 55-250mm pretty good at the close up photography.
I'm wanting to go a bit better so we bought an EF-S 60mm USM macro. Excellent lens, but working at that level of macro is really painfull with the tiny depth of field. It's easy to get a blurred shot. Tripod, big f number, and remote shutter helps of course, but you can't cart a tripod everywhere.
Does the Raynox approach have the same problem or should I just stick to a zoom macro where there is a bigger depth of field? We also have a 28-135mm USM which has a reasonable macro but it's a bit old now and not so sharp.
