Super telephoto reach at a fraction of the size
Okay, so it may be more of a bridge camera than a true compact, but with its massive 25x optical zoom we couldn’t resist bringing the G3 X into our roundup of fixed lens releases. With its extensive 8.8-220mm barrel (24-600mm full-frame equivalent) its larger size can be forgiven, especially considering that achieving a similar focal length on a DSLR would usually involve a lens three times the size. However, while this superior focal range is to be applauded, the G3 X’s optic is not without its drawbacks. With a variable aperture of f/2.8-5.6, the lens sacrifices a wide constant aperture for more reach, forcing slower shutter speeds to be used when at its longest. This, combined with the lack of a built-in EVF (aiding support of the camera when held against the face), and a display that blacks out during its relatively slow 3.2fps burst mode for JPEGs, means it’s not as well suited for wildlife and sports as may first appear. The lens is fairly sharp, though some corner softness can be seen at all apertures. Distortion and chromatic aberration are, however, well controlled considering the lens’ massive zoom range. The 1in 20.9MP back-illuminated sensor is plucked straight from the much smaller G7 X, and while capable of better images than many compacts, it can’t rival the larger sensor found in the GR II. ISO range is 125-12,800.
