UPDATE! Now cross-posted in DAP. This study is really appropriate for MSI, as are other similar ones planned, but I have cross-posted this particular case.
If you’re shooting the 14-24/2.8G, this is a MUST READ. Even for a 12-megapixel camera, let one with triple the pixels.
It explains (shows in effect) why some pros have written me over the past few years, disappointed in the performance of the 14-24/2.8G.
It’s also why I have deferred and prefer not even to make a comparison with the Zeiss 15/2.8 Distagon (which has negligible focus shift)— how does one compare fairly to a lens with strong focus shift? Bending over backwards to be “fair” by compensating for focus shift is not realistic for many shooters.
