Fuji 18-135mm Super Zoom
I swapped the excellent Fuji 'kit' 18-55mm for the 18-135mm 'super-zoom' after reading a number of strong reviews of this lens.
I came to the Fuji X-T2 from Nikon and I've shot with the Nikon D3 and D800 with Nikons excellent 24-70mm f2.8. I am frequently tempted to invest in the Fuji 16-55mm f2.8 which is the closest APS-C match to the 24-70mm on full frame.
The trouble is that the 18-135mm is so damn versatile. It's hard to replace in my workflow. It's not small but is compact enough to sit nicely on the X-T2. The combination fit nicely into my ONA Prince Street Messenger along with the items that I need to take on my commute to the office.
I guess I could invest in the 16-55mm and keep the 18-135mm but wonder if I don't think that I would find a place for both lenses in my workflow.
