I highly recommend the use of a dry cabinet for use in Singapore. I lived there for several years and purchased the cabinet when I first arrived to protect my Leica equipment. None of my lenses acquired fungus, but a set of water glasses in a cabinet were so infected they could not be salvaged.
I would also suggest using a bag that does not have foam padding which will disintegrate into a powdery substance that can get into everything. I had to replace all of the padded inserts in my Billingham bag with custom made cotton cloth pads.
Another suggestion is to use dry boxes with plenty of silicone for miscellaneous bits and pieces. When I shot film, I stored all of my negatives and slides in dry boxes and they were protected.
And NEVER keep your cameras or lenses in the trunk of your car! The heat can ruin your equipment in one afternoon in a hot trunk.
After Singapore, I moved to Hawaii where I continued to use my dry cabinet and boxes to protect my equipment from the high humidity at Waikiki.
I suggest that the tight zoom has distorted the action, making it appear that the horse is jumping into a pile of boards, posts, and wheels. As a breeder of show horses for more than 50 years, and a retired AHSA judge, I feel a lack of freedom in the photos.
