get a wide angle to capture the sceneries and maybe a fast prime lens to capture sweet loving shots at night?
don't bother bringing zoom lens cos u're not going there to shoot nature or candid of others. xDD
Just give a brief idea on what i usually will bring. For free and easy trip, i will bring a sturdy tripod (preferably carbon fibre one as it's much lighted) that's collapsible into your luggage bag (usually abt 60cm or less iirc). However, i will only bring tripod if i am expected to take night scene, sunset/sunrise and maybe indoors (like church interiors etc, even then seldom use). If not, skip tripod, bring a gorripod if u have one.
Camera - A DSLR (D90) and a compact (LX3) (for the wife and the macro/food shots).
Lens - 18-200mm nikon (use for 80% of the time), 12-24mm tokina (15% of the time, mainly for landscapes, buildings etc) and a 50mm f1.8 (for low light, interiors etc)
Since this is your honeymoon trip, whatever you bring, your wife must agree! Don't let your marriage suffers becos of quarrels over the gear,/where you wanna shoot/what time u wanna wake up etc.
I went for my honeymoon trip to Taiwan 3 months back. Nice country to visit with lots of nice scenery. Hence, most of the time the wide angle lens comes in handy for the landscapes (90%). Also very versatile for the streets shots. Used my 40D+Tammy 17-50 most of the time. I brought along the 70-200 too but it was less used. only used it for those performances, etc when the subject is far away. Brought along a tripod too cos I was hoping to get some sunset shots at sun moon lake but didn't manage to cos of the weather. Nevertheless, the tripod came in handy at the least unexpected time - when the host released off some fireworks during one night.
So in summary, for me, the more often used lens is the wide angle lens. I would think a 24-105 might be good to bring along too if you have it. As for the zoom....i think i would choose the 24-105. Also recommend the tripod if your luggage budget can afford it. Just take more of your wife with the nice sceneries and she will not complain...at least tat's true for me...
Enjoy your trip!!
