[12/11/2017] Correct some camera settings info.

[11/11/2017] Added sample photo equipment / camera settings info, Added vignetting and image stabilisation chart, Autofocus speed video

[8/11/2017] Initial post with product photos, sample photos and youtube video

Notice the extra connection pin on the left? This should be the pin for passing the extra teleconverter info to the body

Vignetting is very well controlled with this Leica 200 f/2.8 lens. Even when shooting at maximum aperture, there is very little light falloff. At f/4, vignetting becomes barely noticeable.

Vignetting is very well controlled even at maximum aperture
