I am very impressed by the WATE's overall performance but am underwhelmed by len's front design. You need an adaptor for the requisite filter(s) and this adaptor sits precariously atop a newfangled ring with a rubber O ring. Experience with this Rube Goldberg-like contraption on the recent trip to Antarctica was very disappointing as the adaptor ring froze and the O ring malfunctionned. I will probably wait for a redesigned WATE...
Seems eerily similar to the TE Mk1 vs Mk2 debate years ago !!
