-free, as opposed to the OVF of DSLRs, which is parallax-free). A high-quality EVF is one of the advanced features that distinguish bridge cameras from consumer compact cameras. All DSLRs, by definition, have a through-the-lens OVF. Newer DSLR models typically also allow 'live view' on the LCD screen as an alternative to the OVF, although frequently without autofocus or with very slow autofocus. Mirrorless cameras and dSLTs use LCD or electronic viewfinders.


Large-sensor bridge cameras
