We got our first shipment of Canon 60/2.8 EFS Macro USM Lenses in recently. This lens is Internal Focusing, there is no extension to the lens from Infinity to 1:1 Macro. With the Subal FP-90 port and Aquatica's or Sea & Sea's Standard Macro Ports at 1:1 this lens focuses at about 3/4" (19mm) in front of the port glass. Strobe positioning with this lens and standard macro ports will be interesting!
New Subal setups should probably use the FP-68 port or maybe even the FP-54 port as this will offer a little more working distance.
