Originally posted by Pentaxor I'm not sure if this rumor would become a reality, but if it does, that would be great. for now, the upcoming Sigma 150 macro would suffice.
Rumor is Sigma is releasing 3 more "pro" grade primes for FF bodies. 24mm, 35mm, & 135mm.
The final lineup will be:
24mm
35mm f/1.4
50mm f/1.4 (current)
85mm f/1.4 (current)
135mm f/2
150mm f/2.8 OS Macro (on its way)
Look at the cost for the latest 24mm & 35mm pro-grade glass from Sony/Zeiss, Nikon & Canon. There is definite room for Sigma to enter the market.
The 135mm f/2.0 is basically a fast 200mm prime on your Pentax. You get the lens that renders like a 135mm, has the DoF of the 135mm, the size and weight of the 135mm, but the reach of a 200mm. It is a good length for indoor sports and F/2 is welcome in those indoor venues.
As a long time Canon user you could not have paid me to take Sigma lenses on a job. Nothing about the old Sigma lenses appealed to me. Since the new 50mm f/1.4 and HSM I have been very impressed with what they have produced.
