Sure, I totally anticipate the Nikon lens shall be slower to focus, however I haven’t seen any direct comparisons that show one to be better than the opposite. It seems from MTF charts the Sony is sharper in the middle, however the Nikon is slightly sharper on the peripheries.

LaCA will probably be fairly comparable between the 2, but I would wager the Nikon will have better flare / ghosting resistance, and fewer focus respiration.

These warnings aside, yes, this is a tremendous-sharp lens, particularly at f/1.8 where most other lenses are softer.

The arrow beside the 20 didn’t match nicely into the body and ultimately, I opted to include a part of it with the other visible numbers totally contained. The solar was low and bright, making a shadow selfie a requirement from this place. No, submit-processing was not used to create that completely-placed shadow. Showing up on the right place at the proper time meant that a field home shaded all but the first lane on this college monitor.
