WIDE-ANGLE LENSES
SMC PENT AX 3Qmm f/2.8
The perfect solution for those trying to choose
between the 35 and 28mm focal lengths, as it lies
between the two, making an excellent compromise.
Other attractive features include light weight and
ample (f/2.8) lens speed.
SMC PENTAX-M 35mm f/2
A masterpiece in optical design, because it retains
the same lens speed and superb optical performance
of its predecessor, the SMC Pentax 35mm f/2,
which was 33% greater in length, 36% greater in
weight, and used 52mm filters instead of 49mm.
SMC PENTAX-M 35mm f/2.8
For those not requiring the one stop additional
speed offered by the 35mm f/2 model, the SMC
Pentax-M 35mm f/2 .8 will be found very attractive,
as it is approximately 20% 17ghter in weight and,
needless to add, more attractively priced.
