I've posted "no LCD" comments in a number of threads here over the past 6 months or so. My thoughts are founded in two ideas, I think:
1) A lot of us would like to see a low-cost (Bessa range) M-mount, APS-C sensor camera offered. Removing the LCD removes cost (considerable?).
2) Personally I sooooooo much more enjoy the photographic experience I have with my film cameras than with digital gear! I think it this has to do with a number of things. Not knowing if I got the exposure right makes me slow down a bit and think about what I'm doing. Not having images to scroll through frees up my mind to look at the world... not the LCD. And of course, the joy of anticipation, waiting for my negatives to arrive... kind of like Christmas morning. 🙂
I'm not a professional photographer. I can understand why a professional would like the LCD... their living depends on getting the shots right before leaving the assignment. But for me... give me the simplicity of a D-R3a. 🙂
