Lens Turbo II - Canon FD for NEX-6 - samples - 2/3 faster?

I tested on the canon 35-105mm f3.5 (constant aperature). I've been very impressed. If shutter speed was improved from 1/6 to 1/10, does that equate to 2/3 stop faster? I believe the plant has more blur due to the lens turbo reducing depth of field?

The focus is on the coconut jar. Program Mode.

Without lens turbo - Wide open f3.5 @ approximately 76mm (equals to 105mm)

Shutter = 1/6



With lens turbo - Wide open f3.5 @105mm (to match same view without lens turbo)

Shutter = 1/10

Quality is great... I can't tell the difference.

Yup shocking good with this lens, but this lens is one of the best canon non-L zoom lens. I'll test with my 135mm, 50mm, and 28mm.

For the 50mm I do notice slightly softer with the lens turbo at f1.4. Focusing at the bar code.

This lens does have some fungus, but doesn't seem to matter.

This one was interesting, CA was removed and sharper with the LT.
