Nikon D3200 with 12-24 vs. Olympus OM-D E-M5 with 9-18.

Olympus 9-18 is a perfect match to my Tokina 12-24. The effective length with multiplier is exactly 18-36 both for Olympus and for Tokina. Center performance is similar. Corner performance suffers on the Olympus. I forgot to step it down one step. I can see a lot of purple fringing in the corners on the Olympus. It’s astonishing that the sharpness is the same.
