The specifications of the RF24-240mm f/4-6.3 IS USM for displaying the aperture value The following explains some phenomena that occur when RF24-240mm f/4-6.3 IS USM is used on EOS R/EOS RP.
The discrepancy in the examples below between the value that you would expect to be displayed according to the settings, and the actual value displayed occurs as a result of the specifications (this is not a malfunction).
The specifications of the RF24-240mm f/4-6.3 IS USM
- The maximum aperture value changes in steps from f/4 to f/6.3 when zooming from the Wide-end at 24 mm to the Tele-end at 240 mm.
- The maximum aperture values displayed for certain zoom positions are displayed as representative aperture values with a certain amount of margin.
Matters and cautions concerning the display specifications
- Example 1: A maximum aperture of f/5.0 is displayed in movie shooting mode, but if you then switch over to still photo shooting mode without changing the zoom position, the maximum aperture is displayed as f/5.6. The difference in the example above occurs because the aperture is controlled more finely in movie shooting mode than in still photo shooting mode.
- Example 2: A maximum aperture of f/5.0 is displayed in Av mode during movie shooting mode (with aperture set to 1/3-stop increments), but if you then change the aperture by one click, the aperture is displayed as f/6.3 (rather than the expected f/5.6).
- Example 3: A maximum aperture of f/4.0 is displayed in Av mode during movie shooting mode (with aperture set to 1/8-stop increments), but if you then change the aperture by one click, the aperture is displayed as f/4.0+2/8 of a stop (rather than the expected f/4.0+1/8 of a stop).
- Example 4: A maximum aperture of f/5.0 is displayed in Av mode during movie shooting mode (with aperture set to 1/8-stop increments), but if you then change the aperture by one click, the aperture is displayed as f/4.0+5/8 of a stop (rather than the expected f/5.0+1/8 of a stop).
