I bought a Fuji X100S from a local Fuji guy two weeks ago, and have been shooting it happily ever since. Got this message from a friend this morning: So, here's what I had to say to him. Read on if you care to know what one Olympus shooter thinks of a new toy. -------------------------------------------- Wow, haha. That's a big one. It's early days, still, and I'm really enjoying this two-week honeymoon with the Fuji. I'd definitely have to write at least 10,000 words to do justice to a comprehensive comparison. And that would be both tedious to write, as well as intensely boring to read, I imagine. But, in terms of general impressions… how about some unstructured and unordered rambling? Foremost of all: those "Fuji colors" are *no joke*. Fuji has that long-established heritage in color research, it is perfectly obvious when you look at the output of the X100S. Man, it's good, both in RAW and JPEG. To my eyes, it absolutely nails all the nuances that make a color image work. White balance is impressive, even in mixed lighting; there's great color depth — colors are vibrant, but not "overcooked". And this thing loves shooting people; skin tones are fantastic. There's definitely smoothing happening in JPEGs, which I'm good with, and there are subtle color shifts that improve things as well. Further, Fuji really gets great performance out of that X-Trans sensor. I'm talking mainly about dynamic range. It's a combination of sensor capability, and pushing the shadows up in the JPEGs. This yields a really smooth rolloff to highlights and "soft" shadows which gives images good overall tonality. I'm really happy (surprised, even) with the detail from that Fujinon 23/2 lens coupled with the AA-less sensor. Sharp enough to crop to 50mm (eq) as needed. At high ISO, it trades-in detail for clean, noise-free images—a little too much for my taste, actually. Good subject isolation for close-ish portraits, too. I'm bored with the highly compressed perspective from long lenses; I want some perspective depth and some context. A fast 35 equivalent absolutely rocks for that. Flash metering and ambient light balance is unbelievably good, even when shooting under artificial light without gels (probably going to apply a 1/4 CTO gel over onboard flash, though, to warm it up a bit). And being able to sync at 1/1000 or faster is the bees knees for daylight fill. Onboard raw converter is amazing. Allows +2/-1 push/pull, shadow/highlight tone curves, saturation, film simulation, WB tweaks, sharpness, noise reduction, cropping. Dead simple to do. I like the handling. That extra 1/4" height at the shoulders makes for a slightly more comfortable grip compared to OM-D. Like it slightly better for one-handed operation. Don't like the placement of exp comp dial—rotation direction feels counterintuitive to me too. Falling more and more in love with the aperture dial. AF is competent. Quick is most lighting. Fails sometimes in low light. I sometimes flip to focus peaking, which is good, but not as fast, or accurate, or easy as it sounds. Better with practice? But OM-D is still a faster handling, faster focusing, faster shooting machine. Touchscreen focusing and face detect are unbeatable in dynamic, candid situations (kiddos, street, social gatherings). I like the one-camera-fixed-lens fits-in-a-(big)-pocket thing. Fewer distractions and decisions. You know what I mean. Going to a wedding this weekend and planning to take X100S slung over shoulder on old school 3/8" nylon strap. Everything else stays in the car... I think. Expecting some questions and some conversations, and some nice photos and some missed photos. Would my Summilux 25/1.4 be a better choice? Probably/don't care. Worst to worst, it's in the car if the situation demands it. More likely, I'll get what I get and be happy with it. -------------------------------------------- So there you have it. If you are curious about the X100S and have any questions, I imagine I could help you out. And I'm curious to know—for others shooting both Olympus and Fuji... did you have the same experience?
