A new Firmware Update Version 1.11 for the GR IV has just been released, introducing important feature enhancements and performance improvements.
Changes to V1.11
[Improved Contents]
- The electronic shutter function introduced in the GR IV HDF has been added to the GR IV. Shooting is possible at F2.8 (wide open) with shutter speeds of up to 1/16,000 seconds. Even in bright environments, proper exposure can be achieved when shooting near the aperture’s wide-open setting.
- When the aperture is set between F2.8 and F4.0, the mechanical lens shutter is used at shutter speeds of 1/2,500 seconds or slower, and the electronic shutter is used at speeds from 1/3,200 to 1/16,000 seconds.
- When the aperture is set between F4.5 and F5.0, shutter speeds of 1/3,200 seconds or slower use the mechanical lens shutter, while speeds from 1/4,000 to 1/16,000 seconds use the electronic shutter.
- When the aperture is set between F5.6 and F16, shutter speeds of 1/4,000 seconds or slower use the mechanical lens shutter, while speeds from 1/5,000 to 1/16,000 seconds use the electronic shutter.
- When using the electronic shutter, a “rolling shutter effect” may occur, causing fast‑moving subjects—such as trains, cars, or sports scenes—to appear slanted or to be recorded with circular distortion.
- Improved stability for general performance.
