Here is how the TCON14 looks attached on A12:
And as promised, here are some quick shots taken with A12+TCON-14.

As you can see, there is some corner vignetting and softness visible even in 4:3 mode. But in my opinion, it's caused by two stacked step-up rings instead of just one. In any case, it's not a problem most of the time.
Some more examples, most of them with my usual model

The A12 AF works OK with TCON14 (unlike with GT1 or TC1). Thanks to small depth of field is necessary to be careful about correct focus. But once focused correctly, it can give you some pretty usable results. Of course, you need a model who is willing to stay still for a moment or two
I think it's most useful extension lens for portraits. I guess the upcoming TCON-14B will be even better, but it will be big and heavy addition to A12.
