At BHphoto here, you also get a free UV filter on top of it.
This is not an official deal, so no idea how long it will remain available.
I own this lens and it makes the perfect everyday walkaround lens for the GFX100S, making your 100MP medium format system ridiculously compact and light. When I am out with my family and decide to take the GFX100S, then this is the lens I glue on it.
I tell you this: I am lucky I don’t live in USA, because otherwise I could hardly resist to the mega offer on the one combo in the GFX medium format system, that is totally tempting me. In fact, both, the Fujifilm GFX 50R and the Fujinon GF50mm f/3.5 are now heavily discounted.
And despite all the reviewers make a brilliang job covering the Fujifilm GFX 50R, they have a hard job this time, since it has the exact same performance of the Fujifilm GFX 50S. The only difference is the design, and I strongly invite you to test it out by yourself, because what I loved to handle on the booth, you might hate it.
And in no case I would recommend this camera to left eye shooters, since you are going to cover the screen with your face, and you can forget to swipe the touch screen to access your custom functions while you have your eye on the viewfinder. The swipe function will be used a lot, since there is not D-Pad, where to assign custom functions.
With that said, if you are a rangefinder lover, then you probably already are right eye dominant and the corner viewfinder placement.
