I finally got the #FE 100mm F2.8 STF GM OSS and I love it. This is a quick sample I shot this week with the STF and the a7RV

Yeah, the 100mm has surprisingly great sharpness and great blur!

Tony, any chance you could explain how the STF part of this lens works? It's always been a bit of a mystery to me.

Hey David,

Essentially it has a filter/element inside the lens that is like a graduated ND expect it is clear in the middle and blocks more light as you move to the edges. That is why the f/stop is 2.8 but the t/stop is 5.6. The result of all that is the bokeh is smoother, especially at the edges of the out of focus areas. I hope that is helpful?

Thanks Tony. That is the best description of what makes that lens different I have ever heard. You rock.
