AF 1.7X is not really designed for the macro autofocus. When this is combined with any macro lens, the lens basicly focuses on infinity for some reasons. Only when the macro lenses are used for normal telephoto use, 1.7 tele starts to work normally.
Seriously, A* 200mm macro and Voigtlander 125mm macro are two different macro lenses. Believe it or not, I like the colour and bokeh from Voigtlander macro while A* 200mm macro has a unique image rendering to it.
Nowadays, I really use Voigtlander for non macro shots which is incredibly sharp to use. The colour coming out of this lens is quite staggering.
The manual focusing ring is fantastic, smooth and easy to use. I love it a lot.
A* 200mm macro often is too dark to use. Bumping the ISO is not a great idea which would require a lot of post processing afterwards. I personally dislike flash used on macro work.
