Konica Off Road, 28mm lens, were sold in Japan to the construction industry, Fuji made similar rugged version as well. Currently I have a Konica Zup wide, with 28 to 50mm zoom and Pentax WR weather resistance. Both have help pretty well. My only grip is that both are Dx coded with no manual override, I use a lot of Foma with is not Dx coded and both default to either 100 or 50 while shoot 400. I buy Kentmere 400. In the past I had box given to me with Minolta, Nikon, Pentax, Vivitair. the Pentax IQ zooms held up better than most.
