But the EF-S 60mm f2.8 isn't wider than 50mm :-(

I wasn't implying that the 60 is wider than the 50, it's wider than the 100!

         50mm x 1.6 = 80mm and
         60mm x 1.6 = 96mm

Apparently the need for a 100mm equivalent is very important to this market and 80mm doesn't cut it.

Was there any word on price, maybe it's cheaper. Since this is an EF-S lens, it is possible that it is specially corrected for the needs of the APS-C sensor size.

Bill,

With the 1.6X multiplier, of course, it is effectively a 96mm lens.
It just seems a shame that it is not a full EF mount and, possibly, just a stop faster.
50mm lenses aren't difficult to design. Just look at the f1.8.


Cheers

Keith
