The latest released lenses that are compatible with the X-T30 II are the Meike 56mm f1.7 X, the Sigma 15mm f1.4 DC C and the Meike 23mm F1.4 APS-C.
Fujifilm X-T30 II doesn't have a sensor based image stabilization system but
22 of these lenses already comes with optical image stabilization.
Since Fujifilm X-T30 II has a APS-C sensor, it has a focal length multiplier of 1.5x so you have to multiply lenses original focal length with this multiplier to find the Full Frame equivalent focal length of the lens when mounted on X-T30 II.
