Canon’s G1 X Mark III is its first APS-C sensor compact

Canon has unveiled its first-ever APS-C sensor compact zoom camera, the 24.3-megapixel PowerShot G1 X Mark III. It’s much bigger than the last G1 X Mark II model, with a very similar body to the G5 X compact. It also features Canon’s fast and accurate dual-pixel autofocus and an all-new 2.36 million OLED electronic viewfinder (EVF). To get those big-sensor bragging rights, however, Canon had to sacrifice a few key features from the last model and jack up the price significantly.

Gone is the versatile 24-120mm f/2.0-3.9 zoom lens of the last model (which had a smaller 1.5-inch sensor), replaced with a slower and shorter 24-72 mm f/2.8-5.6 model. It’s easy to understand why Canon did this — with a larger image circle, an equivalent lens would likely have been too large and heavy.

During a call, company engineers pointed out that with a larger sensor, the f/2.8-5.6 lens will still be capable of shallow depth-of-field, and is (a bit) faster than its DSLR or mirrorless kit lenses. Photographers will now have to decide, however, whether they want a big sensor or faster lens, like the one on the (cheaper) Sony RX100 V or the stellar f/1.4-2.8 model on the Panasonic LX10.

The 2.36 million dot EVF was a much-requested feature by owners of the last model, and the G1 X Mark III now has a 3.0-inch vari-angle touch display with touch and drag autofocus. With the dual-pixel autofocus and a Digic 7 image processor, the compact can now shoot at 7 fps with continuous AF tracking or 9 fps with fixed tracking. It also has five-axis optical stabilization and a new type of shutter release that Canon calls “more DSLR-like.”

The dual-pixel AF improves focus speed for both still and video images, but with a serious caveat next to its competition. As with other recent Canon models like the M100 mirrorless, the G1 X Mark III is limited to 1080p 60fps video, while rivals like Panasonic and Sony have cheaper compacts (the RX100 V and LX10) that can shoot 4K/30 fps and 1080p at 120 fps.

Other features include a new panoramic mode that can stitch up to seven photos together, either horizontally or vertically. There’s now WiFi, NFC and Bluetooth, making for easy pairing, photo transfers and remote live-view shooting of stills and video. Finally, there’s a new time-lapse mode that can automatically determine intervals and exposure.

The biggest pain-point for potential G1 X Mark III buyers is the price. It’s available in November 2017 for a stunning $1,299, a good $300 more than the RX100 V which, other than the sensor size, offers better specs across the board. If you really want an APS-C compact zoom, however, the G1 X Mark III is currently the only one in the world.

Existing EV batteries could be recharged five times faster

Lithium-ion batteries have massively improved in the last half-decade, but there are still issues. The biggest, especially for EVs, is that charging takes too long to make them as useful as regular cars for highway driving. Researchers from the University of Warwick (WMG) have discovered that we may not need to be so patient, though. They developed a new type of sensor that measures internal battery temperatures and discovered that we can probably recharge them up to five times quicker without overheating problems.

Overcharging a lithium-ion battery anode can lead to lithium buildup, which can break through a battery's separator, create a short-circuit and cause catastrophic failure. That can cause the electrolyte to emit gases and literally blow up the battery, so manufacturers impose strict charging power limits to prevent it.

Those limits are based on hard-to-measure internal temperatures, however, which is where the WMG probe comes in. It's a fiber optic sensor, protected by a chemical layer that can be directly inserted into a lithium-ion cell to give highly precise thermal measurements without affecting its performance.

The team tested the sensor on standard 18650 li-ion cells, used in Tesla's Model S and X, among other EVs. They discovered that they can be charged five times faster than previously thought without damage. Such speeds would reduce battery life, but if used judiciously, the impact would be minimized, said lead researcher Dr. Tazdin Amietszajew.

Faster charging as always comes at the expense of overall battery life but many consumers would welcome the ability to charge a vehicle battery quickly when short journey times are required and then to switch to standard charge periods at other times.

There's still some work to do. While the research showed the li-ion cells can support higher temperatures, EVs and charging systems would have to have "precisely tuned profiles/limits" to prevent problems. It's also not clear how battery makers would install the sensors in the cells.

Nevertheless, it shows a lot of promise for much faster charging speeds in the near future. Even if battery capacities stayed the same, charging in 5 minutes instead of 25 could flip a lot of drivers over to the green side.
