Sigma dp0 Quattro review – Viewfinder and screen
On the Quattro’s back is a 920,000-dot, 3in screen. It’s sharp and detailed, and can show lots of useful information, including a live histogram and electronic levels display, but it’s neither articulated nor touch-sensitive.
If you want to use an eye-level viewfinder, Sigma’s optional LVF-01 is a hood that bolts onto the camera via the tripod socket and transforms the LCD into a giant electronic viewfinder. This works surprisingly well, but makes the camera even more unwieldy.
Alternatively, you can use an optical viewfinder that slides onto the hotshoe. For this, Sigma provides a display mode that shows all the usual shooting information on the rear screen, just without the live view display. You can also turn the LCD off completely if you like.
