Sony A7R II vs Nikon D810 DSLR System Considerations: Battery Life, Weight, Service and Support

Sony A7R II

Get Sony A7R II and Nikon D810 at B&H Photo.

The mirrorless camera market has displaced the DSLR from many of its strongholds. Various attributes account for this: weight and size of camera and lenses, EVF display, new features, etc.

But product is far more than specifications and a few lenses, and the serious shooter or the pro that must rely on a product to get the job done may have more considerations than are obvious at first glance.

Sony A7R II vs Nikon D810 DSLR System Considerations: Battery Life, Weight, Service and Support

This is a general discussion along with some reality checks on what a system might actually weigh. Particularly for the traveling photographer (especially internationally), such various considerations may be quite important that won’t matter much to the casual shooter. This piece is intended to provoke thought, not to argue for one or the other.

For example, if you need 6-8 batteries, then at least two if not 3 or 4 chargers would be wise, unless one plans to wake up every few hours overnight to swap batteries.
