Indeed the Vivitar 135mm f2.8 is a VG lens and also works well with a 2Xs extender.

I'm quite new to manual focus lenses, so I hope that question doesn't sound too naive.

Was there any digital sharpening involved?

Looking at the photos, there doesn't appear to be, but I'll let Angelus confirm or deny. However, it's worth noting that digital sharpening isn't actually sharpening. Sharp focus means that a field has achieved clarity on the focal surface. Forgive me if this is old hat to you, it may be, but imagine that each point of light is a cone. Out of focus means that the point of the cone is either in front of or behind the film or sensor plane. In focus means that the cone's point is exactly on the film or sensor plane. So no level of postprocessing can correct improper focus. When Photoshop or similar programs say they are sharpening an image they are improving the image's acutance. Acutance is the distinctness of a boundary between two color areas. If there's a very gradual shading (like a gradient), that's low acutance. If it's sudden -- a sharp line -- then it's high acutance. So when postprocessing sharpens an image it actually just changes the acutance.

Also, if that's not an entirely correct explanation, someone point out my errors. I'm still developing my understanding of how real-world light translates into cameras and then retranslates into digital effects.

Nice series, number three is absolutely spot on!
