50mm * 2.7 = 135mm
Get a 50mm f/1.4 or f/1.8, and it becomes a great portrait lens on V1/J1.

24-70mm * 2.7 = 65-190mm.
Get a 24-70 f/2.8, and it acts like a 70-200mm on V1/J1--a very useful lens.

18-200mm * 2.7 = 49-540mm.
The 18-200 can act as a Bigma (50-500mm) on V1/J1. It has VR like the Bigma.

Don't forget to multiply the f-stops by 2.7 as well.

Multiply F/stops???? what the f/stop are you talking about?

That will give you an idea of the image quality (noise) and depth-of-field control you'll have. Does a 65-190/7.5 sound as good now as it did a moment ago?

F/stop and noise? You have your terminology confused.
