Other high-end highlights include a flash hot shoe and the ability to wirelessly control off-board flashguns. To this it adds two control dials (including an S90-style dial around the lens) and a bright, high-resolution OLED screen. The i.Zuiko lens is F1.8 at the 28mm equivalent end and a still very impressive F2.5 at the 112mm setting.īut the spec doesn't end at the lens - the XZ-1 is built around a high sensitivity 1/1.63" CCD which, along with its peers, makes it one of the larger sensors to appear in a compact camera with a built-in lens. And it's clear why the company would want to draw attention to the optics, having created the brightest zoom lens of any current compact while still offering a truly useful range. There's a bright lens, of course, with the XZ-1 becoming the first of the company's compacts to ever wear its respected 'Zuiko' designation. The result of this study is an enthusiast compact that takes the best elements of its rivals and synthesizes them into a very attractive package. With the launch of the XZ-1 it becomes apparent that Olympus hasn't been sitting idly by - instead it has clearly been watching the sector very closely and has studied the available cameras keenly. Sadly, as the years have gone on and prices have dropped, Olympus moved away from this part of the market and it's been a long time since we looked to it for class-leading compacts.ĭespite the falling price of entry-level DSLRs and the arrival of their more compact mirrorless competitors, the enthusiast compact sector has seen a resurgence, with Samsung and Nikon weighing-in and Canon going as far as bringing a second model to the melee (the S90 revived the PowerShot 'S' series to sit alongside the company's stalwart G series). However, the JPEGs appear to have had a degree of noise reduction applied and some large-radius sharpening applied - meaning they don't have the same level of fine detail but the numbers have crisper edges.Back in 2001, when it was possible to charge $999 for a compact camera, Olympus produced the C-3040Z, C-4040Z and C5050Z which featured some of the brightest zooms to ever appear on such cameras. The XZ-1's JPEG output doesn't contain quite the fine detail that can be seen in the converted Raw files. These will be updated when the finished software is available. Raw files processed with a beta version of Adobe Camera Raw and may not represent final image quality. Save as a TIFF (for cropping) and as a JPEG quality 11 for download.Apply a Unsharp mask tuned to the camera, in this case 80%, Radius 0.7, Threshold 0.Set Sharpness to 0 (all other settings default).Load RAW file into Adobe Camera RAW (Auto mode disabled).Because Adobe Camera Raw applies different levels of sharpening to different cameras (this confirmed) we use the following workflow for these conversions: For a (more) level playing field we convert the latter using Adobe Camera Raw. On this page we're looking at both JPEG and Raw resolution. Nyquist is indicated in these crops with a red line. Therefore, even though it may be effectively unattainable with normal equipment in normal shooting situations, an understanding of a sensor's theoretical limit provides a useful benchmark for best possible performance. In theory though, a sensor without an AA filter, when coupled with a 'perfect' lens, will deliver resolution equal to its Nyquist limit. Anti-aliasing filters are designed to reduce unpleasant moiré effects, but in doing so, they also reduce resolution (the relative strength and quality of these filters varies from camera to camera). This limit is rarely attained, because the majority of sensors are fitted with anti-aliasing filters. Beyond this limit (when talking about line pairs usually referred to as the Nyquist frequency) the sensor cannot faithfully record image detail and aliasing occurs. What we want to show here is how well the camera is able to resolve the detail in our standard test chart compared to the theoretical maximum resolution of the sensor, which for the charts we shoot is easy to work out - it's simply the number of vertical pixels (the chart shows the number of single lines per picture height, the theoretical limit is 1 line per pixel).
