Short-term will not be eliminated, the medium-term precarious, the existence of SLR cameras, just in the view is still dependent on traditional optical technology, now look at the electronic viewfinder technology is developing rapidly, the medium-term (five to ten years) is entirely possible to surpass the optical viewfinder. DSLR maintains its existence is the user's massive accumulation of lenses, but that is to hold on to twenty years, and beyond that can not be said that there is no, it is a collection of a few nostalgic people.
