You don't want the size and weight yet you would accept more weight...

 

Designing focal reducers is a complex process, and the price with one would be a fair bit higher.

 

Yes.

 

This is my exact 'Full frame vs. Cropped' argument.  Why carry lenses designed for a different format, just re-badged for the smaller one?

 

I will carry weight if it is warranted, like for a 100mm/1.4 lens or something exotic. Or, alternately, I would buy a 135mm f/2 which was more compact and a lot lighter, as it would be if it was designed for the Fuji X/m43 format.

 

But to just take a lens with a too-big image circle and extend the tube down to the mount doesn't make much sense IMO. I'd rather pick up a Leica M 135mm, or in this case I'd even rather buy a Nikon/Pentax version and adapt it to Fuji X.

 

As for price, yes I understand that even designing a (non-focal reduced) Fuji X variant will cost R&D money.
