Serving as a faithful alternative to the Sigma dp2 Quattro's LCD screen, the VF-41 Viewfinder is an optical external finder that attaches to the camera via its hot shoe. It utilizes an Albada-type inverted Galilean design and incorporates a dedicated framing guide to match the camera's 30mm f/2.8 lens.
+ design, very interesting design , finishing accessory to make your dp quattro become the most interesting industrial design camera + build quality is very high + can be used on all dp cameras including merrill models just set focus in the middle with audible on to get the focus right with practice you can learn where the edges are of the sensor + makes taking pictures with the camera so much easier then try to use the screen in sunshine - a bit to pricy for most people - could have had some kind of safety latch to make sure it doesnt come of by mistake - could have been an electronic view finder same design would have been something to see
You can't see if you frame exact and picture sharp.
