When I bought my K-5, I was also bought the K-7/K-5
neoprene case which Pentax marketed, still use it, really like it.
Although I could protect the K-5 with 18-135 lens, it's just too small for the K-1 and D-FA 28-105mm.
I'm hoping that Pentax will produce one for the K-1. If it was big enough to hold the D-FA 28-105, it would also cover the D-FA 100 macro, 31, 43 & 77 FA limited's, FA 50 and FA 35 etc
Anyone else? Perhaps if sufficient people request it, this might happen.
The alternative third party options just don't appeal
