### Abstract

We propose a framework to perform weak measurements in which photon statistics is employed as the measuring device. Specifically, we show that when a coherent state is utilized as the probe, as a result, a super-Poissonian statistics is obtained whose average number of photons and variance are strongly dependent on the weak effect that takes place in the interim between pre- and post-selection. These results shed new light on the study of weak measurements in what concerns the sensibility of the measurer.
