All those are shot in Bali last year during a Scuba Diving trip...... I prefer very much to use my Sigma 10-20mm due to the wide open landscape around the centre of Bali..... mountains & rice fields. Use the Sigma more than the Tele-Zoom lens. Sadly I haven't brought my EF 50mm f1.4 yet during this trip...... it would be wonderful for taking photos of those friendly people at the Island.
Best Wishes for your up-coming trip.
i'll be going for a short trip to bali end of this month and am considering whether to rent an extra body to avoid having to change lense out in the dusty areas.
