I would love to discuss how the Stylus 1 behaves in bright outdoor lighting, but we've had very little sunshine in the Ohio Valley this winter, so I'm going to focus more on the Stylus 1's indoor image quality--which is nothing short of exceptional. Check out the sample images and you'll notice that I've included several environmental portraits--that constant f2.8 aperture provides some tangible and obvious benefits over the standard f3.5-f3.9 maximum apertures of the majority of currently available P&S digicams and as you zoom out the Stylus 1 stays at f2.8 while those other digicams are fighting to capture indoor images at f4, or f5.6, or f8. The harmonica player was shot (I was only about 10 feet from my subject) in a dimly lit auditorium at approximately 135mm (equivalent) and while there are some minor color anomalies (due to stage lighting) the details are crystal clear.
The Stylus 1 features a 35-area multiple AF system, with 9-area group targeting. The Stylus 1 is capable of both single and continuous autofocusing. It also features AF tracking, Face Priority AF and Eye Detect AF. AF is dependably quick and accurate.
The Stylus 1 saves images and video clips to SD, SDHC, and SDXC memory cards (including MicroSD with SD adaptor) and provides the ability to save images in either JPEG, JPEG+RAW, or RAW formats.
The Stylus 1's built-in flash is located directly above the lens--which is not conducive to red-eye free supplemental lighting. The Stylus 1 also includes a dedicated hot shoe for Olympus flash units with all or most features (depending on the specific flash) available. The hot shoe is a nice addition, but most of the folks who will be buying this camera are available light fans, environmental portraitists, and street shooters--folks who rarely use supplemental lighting.
Olympus claims the Stylus 1 is good for up to 410 exposures with a fully charged BLS-5 Lithium-ion rechargeable battery. The battery charges outside the camera via the supplied charger and requires about three hours for a full charge. Based on my experiences with the Stylus 1, I'd say 410 exposures is a generous estimate. I used the camera for almost two weeks and shot about 450 images total and I had to charge the battery twice, but it has been very cold in Kentucky the past couple of weeks (average daily high temperatures have hovered between 25 and 30 degrees) so cold winter weather may be to blame for some of the discrepancy between what Olympus claims and what I experienced with regard to the Stylus 1's power duration.
The Stylus 1 features a 10.7x (28mm-300mm equivalent) zoom with a fast f2.8 fixed (constant) maximum aperture. Most P&S digital cameras offer zooms with maximum apertures of between f3.5 and f3.9 and those maximum apertures get smaller (let in less light) as you zoom out. The Stylus 1 maintains its f2.8 maximum aperture whether the zoom is set to 28mm or 300mm. So instead of an f8 maximum aperture at 300mm--Stylus 1 shooters can still shoot at f2.8. If you were wondering what makes this camera worth $700.00 that f2.8 maximum aperture at 300mm provides much of the explanation.
The Stylus 1's moderate wide-angle to telephoto zoom covers all of the focal length range (28mm to 135mm) most often used by "Straight Shooters" who usually tend to work in pretty close. When the Stylus 1 is powered up the zoom extends from the camera body automatically by poking its way through a screw-in tulip style lens cover. The cover is removable and can be replaced with a clip on lens cap. When the camera is powered down, the lens retracts and the screw-in lens cover folds up to protect the front element on the zoom. Zooming is fairly smooth and lens operation is very quiet. The Stylus 1 needs between 3.5 and 4.0 seconds to move the lens from the wide-angle end of the zoom range to the maximum telephoto setting. The Stylus 1's new zoom is surprisingly good and even though the lens displays some very minor corner softness, center sharpness is dependably excellent. Chromatic aberration (purple fringing) is visible in some high contrast shots, especially when shooting dark objects against a bright background, but overall, CA is very well controlled. Barrel distortion (at the wide-angle end of the zoom range) is present, but very well corrected and that's impressive optical engineering since well above average barrel distortion is a common fault with small highly complex P&S digital camera zooms.
The Stylus 1 records HD video at 1920 x 1080p @ 30 fps (and other resolutions) with stereo audio. Video clips are sharp, fluid, and hue correct, but there is a brief execution lag of between 1/4 and 1/2 second from the time you push the video start/stop button and when the video actually begins and ends.
The Stylus 1's image files are optimized for bold bright colors and hard-edged but slightly flat contrast. Viewed on my monitor, Stylus 1 images look a lot like the Fujichrome slides I shot during an earlier photographic era - midway between Velvia and Sensia in terms of color saturation.
Overall, reds are a bit warm, blues are a little brighter than they are in real life, and greens/yellows/oranges are impressively vibrant, but (Olympus color interpolation) are always a tiny bit bluish. The Stylus 1's images are highly-detailed and surprisingly sharp. Compared to the Sony RX10, the Stylus 1's image files are generally comparable in terms of overall image quality to its more expensive competitor. The Stylus 1 images are slightly less sharp than the RX10 (in real world usage) and the RX10 does a better job with low-light performance mainly due to the larger sensor size. Check out the Sony RX10 image gallery here. However, the price difference between the two is $600. It will be important for you to decide if the difference in low-light performance and sharper image quality is worth the money. It's a win in either direction. Both cameras are very good!
