EF/GFX v3.0+ firmware feature introduction
About IBIS ( Camera body’s Image Stabilization )
For EF mount lenses without IS function, IBIS was enabled on GFX 100, can be switch on/off in camera body’s function menu.
For EF mount lenses with IS function, IBIS may or may not work depends whether Lens IS switch was set to off or on when Camera powers on. Lens IS and IBIS can’t work at the same time, maybe future after our study.
-
- If Lens IS switch set to off, then IBIS can be used after camera powers on, lens IS will be prohibited.
- If Lens IS switch set to on, then IBIS can’t not be used, Lens’s IS function can be switched on/off via Lens body’s IS switch or Camera body’s menu.
About PDAF ( Phase-difference driven Auto-Focus )
Tuned EF lenses ( Listed below ) can activate PDAF in GFX 100 camera or future GFX cameras with PDAF capability, but not in GFX 50R and 50S.
Lens was tuned in all PDAF focus points of GFX 100, from center to corner ( beyond focus points of 35mm auto corp. mode) , but focus points in corner may performs poor when using certain lens which has serious vignetting issue.
All Lens were tuned in 3 x 3 focus points of Zone AF mode, and in Continuous-AF mode, and from full aperture opening to minimum aperture.
In CAF mode, depends on which lens, AF performance may be poor in smaller apertures and corner focus points , change to Single-AF may improves.
Face and eye detection works too, and movie shooting was improved a lot.
EF lenses not tuned yet will do CBAF in GFX 100. On GFX 50S and 50R bodies, all EF lenses work in CBAF mode, but tuned EF lens may performs better.
Lens tuning was very time consuming, more lenses to be tuned in future once we have lens in hand, stay tuned.
Lens body’s focus range selection may affect PDAF performance, please make sure infinity was included in you AF range selection.
