OK sports fans, I have the 35/2 mated to my XT-1. Yipee. Reminds me of the Leica M-9 and 35/2 Cron, except lighter by a mile. Now about filters; Fuji says to only use a clear protector filter such as their own offering(although none available in the 43mm mount). Says not to put a UV filter on the lens. What are others doing in this regard?
