Re: Pentax smc DA* 50-135mm SDM Issue

I'm of similar opinion to you, I don't take as read that a lens is superior because it has an OEM brand name on.

Many Sigma lens a clearly superior to their OEM brethren especially when they (Sigma) are attacking a market segment, HSM is an example of this where the technology is every bit as functional as Canons USM implementations.

Whereas SDM is IMO not technically very clever if the objective is fast silent focusing but I suspect those were not the design constraints rather suspect they wanted three way focus at all costs.

Those blinkered to OEM only are missing some of the best lens in production.
