If you are keen on an even distribution of focal lenghts between 20mm and
135 mm (and don't want to carry more than 4 lenses), the present PENTAX
line is nearly perfect (and superior to anything Nikon or Canon offers:
FA20mm 43mm 77mm 135mm
94� 53� 31,5� 18�
x1.75 x1.7 x1.75
Canon oder Nikon only offeer:
20mm 50mm 85mm 135mm
94� 47� 28,5� 18�
x2,0 x1,65 x1,6
(Jump too big between 20 and 50)
or
20mm 35mm 85mm 135mm
94� 63� 28,5� 18�
x1,5 x2,2 x1,6
(jump too big between 35 and 85)
