I am finding myself more and more running under the weather with my Nikon D750. Wanted to pick your brains on the need to protect it from the elements. I plan to have that camera for a long time to come, and hence shading $20-$40 on protecting it from the weather seems a worthy investment. So, question #1: Is it worthy investment ? Should I even be concerned with it ? Or can I just rely on the weather sealing of the camera ? question #2: So, if I will go with the protection for the camera, should I get a silicon case for it? Or is it better to get a rain cover ? For either case, what are the options anyone can recommend ? Thanks.
