No, all the cameras you mentioned have optical viewfinders.
The main difference between the single-digit Optios and the two-digit models
is power supply: two AA batteries for the S30/S40/S45/S50/S55/S60 and one
Li-ion for the S/S3/S4/S4i/S5/S5i/S5n/S5z/S6.
Optical viewfinder has been dropped within both families from latest models
(S5n, S5z, S6, S45, S55, S60), sporting a larger LCD.
