In the 1950s, cameras and lenses didn't communicate. Optical bench tests were sufficient to characterize lens
performance completely. Today, optics are only one small factor in the much larger electro-optical systems which
are today's cameras. Bench performance alone isn't enough. For a lens to be useful it must work in concert with
modern cameras' focus, exposure and data systems. This paper explores these numerous issues and their influences
on lens design. Outside-the-barrel ergonomic and systems issues are covered in SPIE paper 7428-19.
Because optical performance has increased so far with modern design software and aspherical manufacturing processes,
optical performance is now the least important factor in modern photographic lens design. Far more important are
ergonomic (usability) and systems-integration factors which determine a lens' acceptance by photographers, and
ultimately, its commercial success. Common SLR cameras tend to have the most advanced systems and features, so they
tend to be the focus of this paper simply because they offer the most to discuss. Inside-the-barrel optics and other design
considerations have been covered in SPIE paper 7428-3.
