Canon 60mm EFS Macro on Full Frame Camera

I've been meaning to post more about using the Canon 60mm EFS macro lens when used with the Canon 12mm Extension tube (MkII only). Here is an image of a Devonshire Cup Coral taken at slightly greater than 1:1 to show the quality available from this lens/extension. Believe me it is extremely sharp and would easily priont at 20"x16" and probably greater. As a lower visibilty lens I can thoroughly recommend it (and in good vis too!). It has to be used with the MkII Extender according to Canon and as I've posted before has a MAXIMUM focus of about 40cm (lobster size). The decreased working distance compared to the 100 is useful in more turbid conditions but still allows viable lighting - I used a single Seaflash 200 on this shot.

Very nice shot.

More proof that EFs 60mm+12mm works but for me a short macro is mostly a medium to large fish lens with the option of 1:1 if when stumble across that really cool shrimp.

I'd really like a 50mm'ish macro with USM. (I have vowed to never buy another non-USM lens) But the lack of infinity(no bigger than a lobster) is a deal breaker for me. Now if maxum subject size was around 3ft, I would be perfectly happy.
