Here's yet another comparison question, but hopefully an interesting one. I have been a GRDII user for several years now, and am a firm supporter of this series of cameras. I don't dislike much of anything about the camera, but with a crack in the screen, and messed up focus issues, I may be in the market to replace the beloved little one. I've spent a fair part of the day doing some research, as I don't often prowl camera news and reviews, and I'm intrigued by the Fuji X10 and X100, although ordinarily I wouldn't look far beyond the GRD line, or in this case, the GRD IV (or even III). Let me start off by describing my needs in a camera: Manual shooting options -- I need to have customization, and ideally, that customization should happen easily and quickly. Zoom lens? Don't really care for it. I rather have a fast, sharp wide lens -- in this case, the X10 does not post any extra benefit with its zoom lens. I am fine with having a fixed lens. Small -- the smaller, the better, generally speaking. A pocketable camera is preferable, but not a deal breaker. I used to shoot with Bess rangefinders (heavy in comparison to most compact digitals), and actually, the aesthetics of the X100 appeal to me because it reminds me of my Bessa. Really, though, the size of any of these three cameras is fine. Generally speaking, I prefer discreet and silent shooting. Video quality: believe it or not, I am hoping to have a still camera with decent video quality. It would be great to be able to shoot short HD clips to use for my business ventures (promoting natural building practices)... The GRDII (my current camera) does nothing for me in the video department. It looks like the GRD IV is lacking there as well. Cost: Damn... the X100 is pretty much the max of what I can afford, if not beyond what I can afford. The price tag is a pretty big drawback for me, and that's actually why I've included the X10 in this comparison. Let's summarize. I want a compact, manual feature-rich camera that is discreet, with excellent image quality, and has a respectable video option. Ideally, the camera cost NOT be $1000+, but if there is some compelling reason to pursue the X100 (good video quality?), I might be able to make it work. I nearly exclusively shoot with manual focus, so it's important that the MF be intuitive and relatively quick to operate. A quality VF is appealing to me, and actually something I miss with my current GRDII. I don't want to depend exclusively on the LCD screen, although to be honest, it's what I end up using most of the time anyway. That about sums it up. Thoughts?
