Instead Canon has chosen to shorten the range. The Mark III's image sensor is bigger, so you need a bigger lens to cover the same range with the same brightness throughout. Its lens covered a 5x (24-120mm) range, with a bright f/2-3.9 variable aperture. The G1 X Mark II had some issues that kept it from getting our top endorsement, but zoom range was not one of them. Compare that with the G1 Mark Mark II, a bulky (2.9 by 4.6 by 2.6 inches), heavy (1.2 pounds) compact.

That makes the Mark III somewhat pocketable-it measures 3.1 by 4.5 by 2.0 inches (HWD) and weighs 14.1 ounces. It's just a little bit bit bigger all around than the G5 X, which has a smaller 1-inch sensor and boasts an almost identical design. The big selling point of the the G1 X Mark III ($999.00 at Amazon) is its size. Image quality is strong, but I question its value and place in the Canon line, especially when the G5 X delivers a longer zoom range with a brighter lens for a lot less money, albeit it with a smaller image sensor. But it comes at the cost of zoom range-the Mark II's 24-120mm f/2-3.9 zoom has been replaced by a shorter 24-70mm f/2.8-5.6 lens. Its replacement, the G1 X Mark III ($1,299), ups the sensor size to APS-C, the same as you get in an SLR, while at the same time sizing down the body.

But there was no built-in EVF, and its 13MP image sensor didn't offer as much resolution as competitors like the Sony RX100 III. It had a solid, wide aperture zoom lens, paired with a bigger sensor than competing models.
