This series on the 60-megapixel Sony A7R IV evaluates the Sony FE 12-24mm f/2.8 GM from f/2.8 through f/8 for across the field sharpness and total performance as to general landscape photography.
The 24mm end of the zoom range looks to be the weak end of the range, but the landscape photographer won’t mind much if good things result with moderate stopping down—let’s look at that.
