Twinjet-i use the 70-200 F/4L for the night/reflection shots with a tripod, so ok lang even if its at F/4. The earlier moon shots, same lens but handheld bec. my old tripod gave up. The moon shots last month, same lens with a tripod and cable release. Other than that, i use a 28-105 III USM or the 18-55 USM for wide-angle, though it isn't really sharp.
Beor-hambugiro lens? ayayyy...naa ra ba ko...hehehehe..but seriously, since i have only one, its really worth it cuz the lens is really sharp...
