The perennial shortage of Fujifilm GF lenses has eased a little, with many lenses in stock as I write this. A few holdouts are still tough to get, but the Fujifilm GF 23mm f/4 and Fujifilm GF 110mm f/2 (two of my favorites!) are back in stock. Update: the 23/4 sold out within a few hours.
Needs vary, but click on the list above to see what I recommend for landscape and similar usage.
