Recently, I have been shooting primarily in increment weather conditions (rain, snow, wind). I am using a Nikon FE2 body with 28mm and 50mm lenses, with the hope of adding a hasselblad system in the near future. My question is this: How wet can I let my equipment get before it becomes a problem? When shooting in snow storms, things inevitably get wet eventually and sometimes the light meter stops working (maybe from the cold?). I am using an umbrella to help protect things, but that only works so well. I'm concerned I am going to damage something. Are there any weather protection covers that are worth buying?
