Abstract
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.
