Sony a7R III Vs. Nikon D850 Weather Sealing Test


Imaging Resource has posted a test on weather sealing of Sony a7R III and Nikon D850, Canon 5D Mark IV and Olympus E-M1 Mark II.

From the result, we can see that Sony a7R III is still working after the rain test, but had water in the battery compartment and it started randomly firing in the off position after the mist test, but the camera returned to normal after being aired out.

While Nikon D850 is nearly no water after the rain test. It seems that Sony’s weather sealing has improved over previous models, but they still have a long way to go to compare with Canon and Nikon high-end DSLR cameras.
