Canon G3 X
The Canon PowerShot G3 X is a List of large sensor fixed-lens cameras, large sensor digital bridge camera announced by Canon Inc., Canon on June 18, 2015. It marks Canon's entry into this product category, alongside competitors such as the Panasonic Lumix DMC-FZ1000, Sony Cyber-shot RX10 and Sony Cyber-shot RX10 II, RX10 II. It has the longest focal length zoom range of any Powershot G-Series, from 24-600mm (35mm equivalent) with a maximum aperture of f/2.8 at widest, decreasing to f/5.6 at 600mm. In terms of overall specification it is the most capable of the current-production G-series cameras but this comes at the expense of overall size and weight - it is also the largest and heaviest of the series. It shares the same 1.0-type ("1-inch") sensor found in the Canon PowerShot G7 X, Canon G7 X as well as both the Sony Cyber-shot DSC-RX100, Sony RX100 III and Sony RX10 cameras. Features * 3.5mm microphone jack for external microphones or recorders. * 3.5mm jack for headphones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop Factor
In digital photography, the crop factor, format factor, or focal length multiplier of an image sensor format is the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. In the case of digital cameras, the imaging device would be a digital image sensor. The most commonly used definition of crop factor is the ratio of a 35 mm frame's diagonal (43.3 mm) to the diagonal of the image sensor in question; that is, \text = \text_ / \text_. Given the same 3:2 aspect ratio as 35mm's 36 mm × 24 mm area, this is equivalent to the ratio of heights or ratio of widths; the ratio of sensor areas is the square of the crop factor. The crop factor is sometimes used to compare the field of view and image quality of different cameras with the same lens. The crop factor is sometimes referred to as the focal length multiplier ("Film") since multiplying a lens f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
