To everybody who helped me : Thanks for the help. You folks were all correct - the subject lens does not exist. I called B&H this morning and the listing they have for a 24-50/3.3-4.0 is actually the non-"D" version of the 24-50/3.3-4.5. Amazing what a typo can do, now if I can just remember where I saw that 300/2.8 listed for $40.00......... ;>) Regards, Bill Briggs [EMAIL PROTECTED]
