Pentax + Ricoh news and more

Metabones released a new 0.50x Speed Booster adapter for the Pentax Q mirrorless camera. It’s called the “Devil’s Speed Booster” because it permits a world record f/0.666 lens speed when a f/1.2 lens is attached. Even “ordinary” f/1.4 lenses will give you f/0.7 output.

Metabones adapters are sold at Amazon and B&H.
