Viltrox EF-FX2 PRO Reviews

Not compatible with X-T30

By Luis
Rated 1 out of 5
Date: 2025-05-10

I read that device was compatible with my Fuji X-T30, only 1 lens works as designed, the EF-17-40 F4-L, all other lenses do not autofocus, Image Stabilizer & aperture ring works but that’ it. Poor construction, the Viltrox logo started rubbing off after 2 days. I have other viltrox focal reducers for my Blackmagic & Canon so I was really disappointed this one did’nt work. I hope you have better luck than me.

No IBIS Support

I have an X-S20 and tried this adapter with the EF 50mm f1.2L USM and the EF 50mm f1.8. There is no IBIS support in either stills nor video mode. Something is wrong with the firmware. Even after updating to v1.05 (found on the Viltrox's Chinese support page because it's absent from their English page) the functionality is still missing. The AF performance is not stellar. It is noticeably slower compared to Fringer EF-FX II Pro adapter.
