What to know before buying
Listing details to confirm
Listing details conflict or are unconfirmed: the dimensions and weight appear both as 51 x 31.4 x 17mm, 19g and as 5.1D x 23.1W x 23.1H centimetres with 0.15 Pounds. It also lists a 1/250 flash sync speed alongside a maximum shutter speed of 1/125 seconds, and describes both Wired connectivity and Optical Pulse wireless technology. The battery is described as built-in and non-replaceable, while another listing field calls for one included nonstandard battery. Confirm the relevant details for the selected listing and camera before buying. The stated automatic light control applies to the GR IV with ISO AUTO. With cameras using a different contact layout, the description says only full flash is available. Planned firmware functionality for GR III/GR IIIx is presented as a future release, not a current confirmed capability.
