Images on this page are of our standard resolution chart which provides for measurement of resolution up to 4000 LPH (Lines Per Picture Height). A value of 20 equates to 2000 lines per picture height. For each camera we use the relevant prime lens (the same one we use for all the other tests in a particular review). The chart is shot at a full range of apertures and the sharpest image selected. Studio light, cameras set to aperture priority (optimum aperture selected), image parameters default. Exposure compensation set to deliver approximately 80% luminance in the white areas.
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). Beyond this limit (which when talking about line pairs is usually referred to as the Nyquist frequency) the sensor cannot faithfully record image detail and aliasing occurs.
This limit is rarely attained, because the majority of sensors are fitted with anti-aliasing filters. 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). In theory though, a sensor without an AA filter, when coupled with a 'perfect' lens, will deliver resolution equal to its Nyquist limit. 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. Nyquist is indicated in these crops with a red line.
On this page we're looking at both JPEG and Raw resolution. For a (more) level playing field we convert the latter using Adobe Camera Raw. Because Adobe Camera Raw applies different levels of sharpening to different cameras (this confirmed) we use the following workflow for these conversions:
|JPEG (5184 x 3456) 4.7MB||Raw (5184 x 3456) 4.8MB|
The EOS 650D's JPEG files display slightly less aggressive sharpening than those of its predecessor, the Canon EOS 600D. This has little meaningful effect on perceived resolution though. You can discern all nine lines of our resolution chart at around 2400 LPH, which is certainly in the ballpark of what you'd expect from an 18MP sensor and sensible image processing.
Processing the camera's raw file with ACR 7.1 and then applying a moderate amount of sharpening in Photoshop yields a 'cleaner' image without any sharpening halos. You can see separation between lines perhaps as far as 2600 LPH, but moiré patterning is a significant presence at that point.

Canon has issued a warning to owners of the EOS 650D/Rebel T4i that the rubber hand-grips of some models may turn white, and produce a chemical that can cause an allergic reaction. According to Canon, the chemical, zinc bis (N,N’-dimethyldithiocarbamate), is not used in the production of the camera but is a potential by-product of a chemical reaction between other substances found in the hand-grip. Click through for full details.
Updated: We've had a production sample Canon EOS 650D/Rebel T4i for a few days now, and we've been busy running it through our usual studio and real-world tests, ahead of a full review. We've updated our previously-published preview with a gallery of 27 real-world samples from the production camera, both JPEG and converted Raw, and included some Raw files for you to examine yourselves. We've also added the 650D to our studio comparison database, allowing you to check out how it compares to its peers and predecessors in our standard studio test scene. Click through to see the additional samples.
Just Posted: We've been shooting with Canon's latest entry-level DSLR - the Rebel T4i (EOS 650D), and have prepared an hands-on preview. The T4i shares many of the headline specs (18MP CMOS sensor, 9-point AF system, 1.0M dot flip-out LCD) with its predecessor, the EOS 600D / Rebel T3i, but significant changes have been made to every one of those features. The result is the first touch-screen DSLR and the first EOS to offer continuous AF in movie shooting mode. Read our preview to find out more about the 650D's features and what its 'Hybrid AF' really offers. The preview includes real-world samples and low-light studio shots.
Canon has announced the EOS 650D (known as the Rebel T4i in North America), and 18MP touch-screen DSLR with a sensor-based hybrid AF system for improved focus in movie and live view modes. The camera gains the all-cross-type 9-point AF sensor from the EOS 60D and can now shoot at 5fps. It also adds stereo mics for its Full HD video recording, which is available at 30, 25 and 24fps. The camera will be available from the end of June at a price of $849, body only, $949 will the 18-55mm IS lens or $1199 with the co-announced 18-135mm STM IS lens.
When the Fujifilm X-T2 arrived, it was more than just a modest upgrade to the already impressive X-T1. While the new X-T3 hasn't changed the overall design of the camera, this model is way more than an upgrade; rather, it's a quantum leap.
The Movie Maker is a compact, motorized slider designed for phones, action cams and small mirrorless cameras. We think it's a fun little kit and a good value proposition for the cost, provided you can work around a few of its weak points.
Nikon's Z7 is the first camera to use the all-new Z-mount, the company's first new full-frame mount since 1959. We've put together our first impressions based on quality shooting time with a pre-production camera - check out what we've found.
