Hello
My 85mm f/:1.4 FA , 43mm f/:1.9 and 35mm f/:2 FA Pentax also do not allow
f/:19 between f/:22 and f/:16
Beware, it seems that the 20mm f/:1.8 DG is not very good (not as good as
the 20mm Pentax )
If the price is not really lower than the Pentax, you may prefer the Pentax
except needing great aperture such as f/:1.8
The 105mm is an excellent lens. I regret that its hood is a screw in hood
the 14mm do not exist by Pentax !!! there is also a Tamron 14mm f/:2.8,
nearly as good (seems that the Sigma is a little better) but the Tamron
looks prettier !
The Sigma 70-200mm f/:2.8 EX was an excellent lens for Pentax owner until
they sell it more expensive than before ! (in France)
See you
Pentaxclover
