The sharpness performance is definitely better. Only the attenuation through the glass is comparable. In the FFC there are two elements of pure fluorite crystal. This is outstandingly transparent at 350 nm.
But there are two more elements from regular molten glass also in this lens collection. Therefore the pure amount of "normal" glass is about the same.
Nevertheless the transmission at 350 nm should be 90%.
