Ok, it's more or less official. We're going to Africa for a safari in about 2 months. We (me / wife / 5 yr old daughter) be traveling with the couple we always do big trips with, and most of the time will be spent on a safari. Here's what I'm mulling over... Safaris require LONG lenses, and I don't own anything longer than the XF 56. I wouldn't mind a longer lens, actually, but I don't have one today. CONSTRAINTS: - I want a LIGHT bag, so it's just the XT1, not bringing film or the X100. - This trip is EX PENSE IVE. So I reeeeally don't see me blowing over a grand on a new lens. Both of those things have me thinking... maybe I should just not even TRY to get long shots of animals close up. Maybe I should live with crops of the 18-55, and then maximize the people and landscape shots. I realize this trip is probably begging for the 18-135 lens, given its weather sealing and Do It All range. I just don't love the overlap with the 18-55, which I own and love. So, the big question: Do I go get a 55-200 lens for $600 and swap lenses more often, or I just save the money and use what I have?
