Update 26 December: all the deep discounts shown below went away, but click here to check current status.
This looks like a very good time to buy Fujifilm X lenses.
I use my own diglloyd Deal Finder tool to check prices on various brands every day.
The deals on Fujifilm XF lenses stand out with their 20% to 33% discounts.
Fujifilm must be feeling some kind of market pressure to offer such steep discounts. I’ve used/tested most of the Fujifilm X lineup, and my personal picks would be the 14/2.8, 16/1.4, 23/1.4, 35/1.4 and 56/1.2 APD.
