I recently did this sound comparison (below link) and was disappointed that the convenient and elegant design concept of the SMAD-P3 multi-interface hot shoe mount for UWP-D11 is undermined by noise and hiss compared to using the K2M-XLR adapter or even 3.5mm direct to camera.
I'd be interested to hear from anyone else who is having similar or different results with the SMAD-P3 especially on A7s2 and RX10
Thank you
