I've recently purchased one of these lenses (see link):


www.ebay.com.au/.../380376865424


However it is not the same lens reviewed on TDP:


www.the-digital-picture.com/.../Canon-EF-100mm-f-2.8-USM-Macro-Lens-Review.aspx


Only after purchasing it I found that there are more than just two Canon 100mm 2.8 macro lenses. Does anyone know anything about my lens? Is it like a version 1 of the non-L lens, what is it? I can't find any info or review yet.


The first tip-off that it was not the same lens was that the ET-67 hood didn't fit. And this lens extends when focusing. Also it has a 52mm filter thread instead of 58mm.


Finally how does it stack up against the non-L lens reviewed on TDP?


Cheers,


William.
