From theoretical predictions, the introduction of 8-m class telescopes permits one to extend Surface Brightness Fluctuations measurements from the ground to [FORMULA]7000 km/s, with a precision that is comparable to current space-based measure ments. We have measured I-band SBF in IC 4296 in Abell 3565 at [FORMULA] km/s with the ESO Very Large Telescope. Adopting the Tonry et al. (2000) calibration for I-band SBF we determined a distance modulus of [FORMULA] mag corresponding to a galaxy distance of 49 [FORMULA] 4 Mpc. This result is consistent with the HST observation from Lauer et al. (1998): [FORMULA] mag.
