Helium Design Lab Builds a Precision Grip for the Leica SL3

SL3 shooters who've done a full day on that body know the ergonomics ask a lot of your right hand. Helium Design Lab builds grips with actual photographer input rather than engineering committee logic, and a properly designed grip on a large mirrorless body like the SL3 changes how long you can shoot before fatigue becomes a liability. Niche product, small audience, but if you're in it, you already know why it matters.
