What is the effective focal length and speed of the combo?

"Mounted between a mirrorless camera and a SLR lens, Speed Booster® increases maximum aperture by 1 stop (hence its name), increases MTF and makes lens wider by a factor of 0.71x."

Thus, 500/8 becomes 355/5.6. FOV eq. depends on the sensor size With a 1.5x APS-C sensor, it goes back up to ~532 mm eq. The Speedbooster becomes just that, increasing speed by one stop, while leaving FOV essentially the same.

So What Moose
