Hi everyone. I shoot with a D850 and D780, mostly landscapes and architecture, with some people as well. I’m interested in astrophotography, but haven’t played much. I own the 14-24, and with the deals I’m seeing on sigma refurbished product, I’m considering the 14mm 1.8. Is there enough of an improvement to justify the approximately $1500 additional dollars? Looking forward to hearing others thoughts.
