I thought I already post the question but cannot find it in the forum. Hope I am not repeating myself, otherwise sorry !

Some people say the Nikon TC does swallow a few stops of light, some other say it does not. The TC is certainly not cheap, but a 100mm f1.8 would be much expensive.

Plus the TC would help anyway for other lenses too.

Who is right, who is wrong ?

A 2x TC converter loses 2 stops of light.

A 1.4x TC converter loses 1 stop.

So the 50 f1.8 + 2x => 100mm f3.5 (approx)

The loss of light is one of the side effects of using a TC. The good news, is most consumer zooms are still slower at 100mm than the f3.5 you'd have with the 50f1.8+2x TC.
