Nikkor 50mm f1.8 on FUJIFILM X-Pro2
Technically a pancake lens, it isn't annoyingly long with the adapter. Any old Nikkor longer than this is pretty dreadful to carry because the front end weight that makes the camera hang forward. For instance, the AIs 28mm F2.8, wonderful lens, but not to carry with a neck strap on this camera.

If you used this lens on a Nikon system you know it's a good lens, great even at the price it sells for. But on the FUJIFILM X-Trans sensor its outstanding, tack sharp, no vignetting, dramatic bokeh, film like rendering if you want it. I use this lens with high contrast red focus peaking, the manual focus ring is superb. I've always preferred manual focus and the red focus peaking is an amazingly helpful tool, to me it exceeds auto focus performance.

I chose the Metabones adapter because of its design, I like that its straight from the lens to the mount. I have tested the $14 K&F Concepts adapter with this lens and I see no difference in performance. This lens sells regularly at $35 usd on eBay(prices are rising fast due to mirrorless popularity), with the Metabones adapter this a $134 combo that is perfect front to back. Very reasonable at that price, but only $49 with the K&F adapter. Get it if you don't have one, there is a great feeling of ease when you are shooting top quality glass that costs less than $50, drop it, smack it on a table who cares. I can't think of any reasons not to own this set up, Nikkor lenses are proven performers with some of the best build quality in the world. No brainer.
