This is the latest shots I have taken. Those pics at Raffles were taken without flash too set at ISO 200/400 Manual 1/80 and 1/125. Using both lens EF-S-18-55 IS Kit and EF 75-300MM f/4-5.1III USM.
Pics at West Mall were taken only with EF 75-300MM f/4-5.1III USM set at ISO 400/1600 and without flash again.

Wanted to see what the differences when using tele-len to shoot from level 1. Of course, as mentioned by some seniors using flash should be better off but built-in flash is not powerful enough for the distant, I think ? Next round will try with flash to see the differences.
