I've owned a DP2m for a little over a year. The 24 x 36 inch prints I produce from this camera rival prints from my Canon 5D2 with Zeiss and Canon L lenses. I usually use the camera with a tripod but I essentially bought it as a carry everywhere camera. I've come to the realization that I really hate using this camera when handheld. The reason is the pitiful little Sigma optical viewfinder I have attached to the hot shoe. I wear glasses and I cannot see the entire bright line frame when composing a photo. There is not enough flange area around the eyepiece either to shield out extraneous light. I can't stand using the rear LCD with arms extended like a wobbly sleep walker or Frankenstein's monster taking it's first nascent steps toward the light. The glare and reflections bouncing off the LCD don't help when composing a shot either. Maybe I'm just too old and grouchy to get used to "new" technology.
This is very disappointing because I love working with the rich, deeply robust files this little camera produces. I quickly tried a voigtlander finder once in a camera store but I recall not being very impressed with it either. I considered a Hoodman but it's such a cumbersome rig that I know I'll end up wrestling with it as well. Has anyone tried different makes of optical viewfinders with this camera that are better than the Sigma viewfinder? And... if Sigma is listening, please make an accessory EVF for the DPm series. The camera is not much good if you can't see through it.
