John Tan said:Is the theme out yet or announce on that day only? I think wide angle + some mid range zoom will be enough...unless the theme is about 'sport for life'...
All the 3 themes will only be announced on that day.
Bring along a wide angle and mid telephoto should be sufficient. E.g. EF 17-40L and 70-200mm f4 or 2.8.
Flash light may be required for the last theme which is in evening/night time.
