I packed for my first genuinely long personal trip, ten days, three cities, mostly on foot or public transit, exactly the way I pack for a wedding, and paid for that decision every single day carrying a bag that never got lighter no matter how much I told myself I'd use everything in it. I've rebuilt how I pack for travel specifically since that trip, and this is the kit and the reasoning behind every piece of it now.
A wedding kit is built around covering every possible moment across a single, predictable day with backup gear for anything that fails, redundancy is the entire point. A travel kit gets carried for ten straight days across unpredictable terrain, weather, and transit, where every extra pound is a cost paid repeatedly rather than once, a genuinely different optimization problem that took me an uncomfortable first trip to actually internalize.
I carry a single camera body for travel now, not the two-body redundancy setup I'd never leave home without for paid work, a decision that felt genuinely uncomfortable the first time I made it. A body failure mid-trip would be a real problem, but the odds of that happening are low enough that I've decided the daily weight savings across ten days outweighs that risk for personal, non-paid travel specifically.
Rather than my full lens bag, I now carry exactly two lenses for travel, a wide-to-normal zoom covering street scenes and architecture, and a compact telephoto for candid portraits and details, deliberately chosen to cover the actual range of subjects I photograph while traveling rather than every focal length I own. This alone cut a genuinely significant amount of weight and bag space compared to my old habit of packing four or five lenses "just in case."
My own A7 IV is a reasonably sized full-frame body, but after that first uncomfortable trip, I've genuinely considered a smaller mirrorless system specifically for travel, having tested lighter APS-C and Four Thirds bodies for reviews and felt the physical difference across a full day on foot. For anyone building a dedicated travel kit from scratch rather than repurposing existing gear, a genuinely smaller system is worth serious consideration over sticking with a full-frame body purely out of habit.
I used to pack a full-size tripod on every trip and used it maybe twice across a full ten days, mostly guilt-carrying weight I never touched. I now carry a genuinely compact, lightweight travel tripod, sized specifically for the kind of quick, opportunistic long-exposure or low-light shots I actually take while traveling, rather than the studio-grade stability I don't need outside paid work.
Following the same two-card-splitting habit I use for weddings, I carry several smaller cards rather than one large one, backing up to a compact portable SSD each evening rather than trusting cards alone across ten full days of shooting. This is a genuinely different backup rhythm than a single wedding day requires, and losing a card mid-trip without a nightly backup habit would cost far more than a single day's images.
I traded my padded, dedicated camera backpack for a smaller sling-style bag with a padded insert, genuinely less protective than a full camera backpack but meaningfully lighter and faster to access one-handed while walking, a real tradeoff I've decided favors accessibility and weight over maximum protection for travel specifically, while I still use the full backpack for paid work where the calculation is different.
A second flash, a full set of filters, a laptop for daily editing, and a spare battery grip all used to make the cut for every trip regardless of whether I'd realistically use them. I now leave all of it home for personal travel, editing on my phone during the trip itself and doing any serious editing once I'm back, a decision that's cut real, meaningful weight without costing me images I actually wanted.
My most recent trip, six days through two cities, used a bag roughly half the weight of what I carried on that first uncomfortable ten-day trip, and I came home with images I was genuinely happier with, partly because a lighter kit meant I was willing to keep shooting later into each day instead of resenting the weight on my shoulders by mid-afternoon. The redundancy and range I build into a wedding kit exists for good reason on paid work, but carrying that same instinct into personal travel was costing me more than it was protecting, and I wish I'd worked that out before a decade of overpacked trips rather than after one particularly miserable one.
