Canon PowerShot G5 X
8.8 - 36.8 mm, 20.20 Mpx, 1"
Question about Canon PowerShot G5 X
The test says: "With 24mm very good wide-angle range". but the camera specifications state 8.8mm. Which is correct? I need a wide-angle camera (similar to approx. 10mm for SLRs).
Both are correct.
The lens has a smallest focal length of 8.8mm, but related to the 1" sensor of the camera. To convert this 8.8mm into 35mm format (KB) you have to multiply the 8.8 with the camera's cropfactor of 2.7. This results in 23.76mm.
This camera has a 1 inch sensor and thus a cropfactor of 2.7. 8.8mm then corresponds to just under 24mm in full format.
The sensor size is relevant. Whether SLR or mirrorless or compact is irrelevant. What do you mean by 10mm? With which camera? APS-C SLR / mirrorless? Full format? 10mm on APS-C then corresponds to 16mm KB for Canon and 15mm for the others. There are only a few 10mm lenses for 35mm cameras on the market. E.g. from Voigtländer or Laowa. There are also 12-24mm lenses for 35mm cameras. That is already very wide.
Compact cameras with such ultra-wide-angle lenses do not exist on the market. The most compact way is with a mirrorless APS-C camera and a 10-18mm lens (or something similar depending on the manufacturer).
