The Mid Offset Ti Plate is designed for modern, full frame mirrorless cameras (Sony A7/A9, Nikon Z, Canon R platforms) where the tripod socket has been shifted towards the lens.
The new Full TIplate is a longer adjustable plate optimized for larger camera bodies and the foot on telephoto lenses.
The new Micro TI is a truly minimalist plate, designed for very small cameras, and for situations when minimizing weight and size are absolutely critical.
