Yes, the SMCT 120 2.8 and the SMCP 120 2.8 appear to be the
same optical design. I've shot with the SMCT and it's every bit as
good as the 105 SMCT which is saying a lot. The design of these 120 lenses
seems to match the 105 2.8's ( both SMCT and SMCP ) exactly except on
a slightly larger scale.
The 120 2.8 SMC-M is also 5 element but a different OPTICAL design
altogether.
Has anyone here done a critcal comparison/test of either
the SMCT or SMCP 120 2.8 to the SMC-M 120 2.8?
What's a little odd is that the SMCT 120 2.8 is a 49mm filter thread
and the SMCP 120 2.8 is a 52mm filter thread even though they are
same optically. BUT when the SMC-M 120 2.8 came out they reduced
it down to 49mm filter thread again but changed the optical design
to either save weight and/or cost and/or size. ( or to be positive,
maybe to increase performance??? ).
