In my Olympus 45mm F1.8 VS Nikon 1 32mm F1.2 AF Speed Comparison I am comparing the AF speed of these two lenses in three different lighting conditions: daylight, low’ish indoor light (light coming from the window) and very low light.
Here are the exposure parameters:
– Daylight: F1.2, 1/1250s, ISO200 (a lot shorter shutter speed on Olympus OM-D E-M10, because I forgot to change ISO and left it on ISO3200)
– Low’ish light: F1.8, 1/200s, ISO3200 on Olympus OM-D E-M10 and F1.2, 1/500s, ISO3200 on Nikon 1 V1
– Very low light: F1.8, 1/60s, ISO3200 on Olympus OM-D E-M10 and F1.2, 1/125s, ISO3200 on Nikon 1 V1
There doesn’t seem to be much of difference between the AF speed of the Olympus 45mm F1.8 and Nikon 1 32mm F1.2, regardless of the lighting conditions. Of course, cameras also play their part in regard to AF performance, so this could test could look a lot different, if the lenses were used on latest and greatest micro 4/33 and Nikon 1 cameras (say Olympus OM-D E-M1II and Nikon 1 V3). Also, since both cameras use contrast AF (Nikon 1 V1 in low light), how fast they will focus also depends on the contrast in the scene and whether you as a user can identify high contrast edges and aim with the AF box in the direction of those high contrast edges.
