Hauxon

I had the 60 few years back and optically it's fine and still provides shallow enough dof for portraits.  It was slow to focus but secure and it's probably much better now with the latest firmware upgrades.  I kind of miss having a macro lens ..but he 56 is just osom, and I can't justify having both.  It's got a beautifully made metal lens shade and I wish Fuji would supply those with the newer lenses. 
 
Here's a macro shot with the 60 macro.  It renders beautifully.  I also wish they made it 1:1 so if you want to shoot smaller insects (subjects) you will need to buy the tubes.

I´ve had mine for a week now.   It seems to be the lens we were all hoping for, it's very sharp wide open at 400mm and focus speed and stabilization seem good.  I had the Canon 400/5.6 L before and the 500/4.5 L.  The 500mm lens is the best lens I've ever had and worked great with the 1DsII I had at the time.  The X-T1 + the XF100-400 may not be there but  getting closer and hopefully the X-T2 will have improved tracking capabilities.  Overall I'm very pleased with the lens.
 
Here's a test shot with the X-Pro2 (pre-production model) + XF 100-400.  Lame subject ...but great feather detail.

 
I also think it looks quite nice on my GS X-T1.

On this photo you see the same "issue" what I also saw with the olympus 300mm F4. When branches are really close to the subject, they are shown "double".
Here I don't like the bokeh at all ... just something to remember when taking photos I guess : "make sure that there's sufficiant distance between subject and background"
 
can't wait to test my copy though , it's sitting here waiting until I got a fuji body (xpro2)
