We present ISO (Infrared Space Observatory) observations of the planetarynebula Lindsay 305 (L 305) in the Small Magellanic Cloud. L 305 is veryprominent in the ISOCAM frames at 6.75 and 11.5 $\mu$m, although it is underthe detection limit at 4.5 $\mu$m. The obtained spectral energy distributionshows a strong mid-IR excess, which, depending on the amount of energy radiatedat wavelengths longer than 11.5 $\mu$m, may be as large as $\sim 1500L_{\odot}$. However, since an accurate estimate of the total nebular luminosityis not available up to date, the evolutionary status of L 305 can not yet beconstrained precisely.Comment: 4 pages, 2 figures, to appear in the Publications of the Astronomical Society of Japa
