Question: is the 5d classic weather sealed?
Answer: The original 5D has no weather-sealing whatsoever; Canon never claimed that it did. ... The 6D and D610 do have some amount of gasketing, but neither can be expected to be as weather-resistant as a top-tier 1D/D4 body. I enjoy shooting with a 5D, but it is a fair-weather-only camera.
