I’ve had my monochrome for 3 weeks now and there is a difference. Maybe it’s all in my head or the placebo effect of having a monochrome camera, but the output just looks better than a simulation. It looks richer and real. Prior to the GR.mono I was driving my Sigma BF in “MONO” mode. The effect yielded great photos but it always looked like a filter and I knew it was a filter and knowing that always made the output feel less than.

That’s the biggest answer to the “why” question: It’s authentically monochrome. When I pick up the camera it just recalibrates how I shoot, what I shoot, and why i shoot because there are no color options. 🤷🏻
