![]() ![]() Much has been written about the quality of the bokeh created by different lenses, but the general rule of thumb is that the more light a lens can capture-measured numerically as its aperture, or f-number-the blurrier the background can be. This blur is often referred to by the Japanese term bokeh. It allows you to better control the depth of field in images, making it possible to isolate your subject and create a blurred background. There are many inherent advantages to a larger sensor. The Panasonic GH5 II uses a Micro Four Thirds sensor and lenses And even though the format is smaller than APS-C, it is significantly larger than a smartphone or point-and-shoot image sensor. Micro Four Thirds is the oldest mirrorless system, so there are plenty of lenses available. Its kit lenses are typically around 14-42mm in design, but don't give you a wider view than an 18-55mm APS-C lens. Micro Four Thirds, which has a 2x crop factor, is another popular mirrorless format, with cameras available from Olympus (now sold as the OM System brand) and Panasonic. This means that the 18-55mm kit lens that is bundled with most DSLRs covers a 35mm field of view equivalent to 27-82.5mm. The standard APS-C sensor features a "crop factor" of 1.5x. This can be a bit confusing when talking about a camera's field of view, as focal lengths for compacts are often expressed in terms of 35mm equivalency. ![]() Most consumer ILCs use image sensors that, while much larger than those found in point-and-shoot cameras, are somewhat smaller than a 35mm film frame. The Fujifilm X-T4, and other Fujifilm X cameras, use the APS-C sensor size
