What I hope a Voigtlander Color Skopar lens on a Vito B can do

This little tyke here was taken on a Werra II camera. It has a Carl Zeiss Jena Tessar (50mm F2.8) lens.

The one reason I don't shoot with this camera more is it belongs to my wife's departed and well-missed father, Cyril.

It also has a selenium meter which will one day run out. I hate that.

So, when I bought the Voigtlander Vito B viewfinder with a Color Skopar lens at 50mm F3.5 this weekend, my big hope to have a viewfinder that could take low natural light shots like the one above. There's something very creamy and delicious about the image (is the milk bottle making me hungry) which I'd like to make with the Vito B.
