6 months??? where r u going?
for long trips on the go (though i've not been on one, though working i've been for more than that), other than weight, you should consider backups too as the places that u go may not have replacement.
the following is what i do, as i crack my brain for every trip. they are still heavy for me but i compromise little for my usage. the below is listed in terms of priorities.
1. camera body
- confirm bring DSLR?
- consider bringing backup DSLR body, get a 2nd hand entry level DSLR cost you only S$400-800. without the lens, you can buy one of those hard plastic food containers (like lock-lock) and fit it snugly within. chuck into check in and if anything ever happens to your main DSLR, you still can use the same lens, cards and batteries (check compatibility).
- some people bring compact along with DSLR. the compact is useful for concerts or other places where DSLR is too loud, or if the compact is weather proof or water resistant to superficial water eg rafting, replaces the DSLR. however, the need for different charger and accessories can make bringing an additional compact system heavier than an extra DSLR body.
2. camera lens
- at least two lens, same reason as above - backup.
- what lens to bring varies greatly on your usage
- maybe one of them can be a 18-200mm that fits all
- the other can be one that u can potentially survive on for all your pics, for me more than 1/2 my pics are on ultrawide, so i'll bring my 10-20mm. some survive a whole trip on 50mm f/1.8.
- if you dun want to bring a 18-200mm, bring the 2nd most frequently used lens
- if a third lens considered, that can be a light prime. e.g. 50mm f/1.8
- is there occasions that you die-die must bring a fast-tele? drop this idea if there are none as such lens weighs far more than a kg. occasions that fast tele is very useful, other than sports and safari, is crowded festival locations or stadium with fixed sitting locations. alternative of fast tele-zoom is fast tele prime. if nikon, 180mm f/2 is an option.
3. lens cap & protective filters
- you dun have to bring one for each lens even if different thread size
- buy a step-up rings for each size, all up to 77mm, reason rings are much lighter and easier to carry
- then bring 1 extra 77m cap. (if you kiasu, 2)
- likewise same for UV filters, buy the cheapest ones for backup
- put into rounded hard plastic food containers (like lock-lock) and fit it snugly within. you can find more of these food container options at big supermarket - like carrefour.
- yes, these containers do weigh, but not too much, and you can check them in with no worries, which to me is worthwhile
4. batteries and charger
- 2 to 3 bat should be safe. if you really want to cut down, at least 2 bat. 3 is if your DSLR need 2 bat power a day. 2 if your DSLR or daily shoot is low on consumption
- bring >1 charger? i take that risk with only 1 charger as spoilt charger is so rarely heard of.
- plug convertors? if u going to only one location with a single type of plug, i'll try to see i can get that for my charger instead of using the UK 3 rectangular pins and the universal convertor, which can be loose on the socket due to the weight. but i'll still bring a universal convertor as backup. shop around for a light one (put on your hand and estimate) as some universal convertor are super heavy. for some plugs, there is also options but not so easy to find, i know the 2 flat pin us-japan-taiwan plug can be easily converted to 2 round pin euro plug by a flat convertor instead of the block-like univesal convertor
- extension cords can be considered. go DIY shop and feel for the lightest 3 socket set. ask the DIY shop if they can help you shorten the rubber cord to 1m. it saves a lot of weight and 1m is usually more than enough for the wall plug to the bedside table. of cos, this cord adds up weight, but it is convinient when you need to charge laptop, handphone and DSLR battery - unless you bring less than that or dun mind the hassle of checking the power and change it when one device is powered up (affect your sleep).
5. cards, laptop and storage
- now with cheap cards, brings lots of them that will last you for a day (or more if you are hiking without your main luggage).
- you obviously cannot only use cards as u r out for 6 months.
- u also need to worry abt spoiling of storage as you r out for 6 months.
- plan 1-2 locations of storage. considering if cards only for temp storage
- for me, i use a netbook (asus eee PC 910), a OTG, a portable HDD (ok, i know that is heavy).
- consider a netbook instead of laptop becos the charger and cords used by the netbook is also smaller and lighter. however, netbook may be limited in functions (no photoshopping) and internal HDD size.
- an OTG is on the go card reading portable HDD. it can read cards and transfer (picture viewing is more expensive and not-easy-to-browse though safer, i'm not sure how much they cost now over non-pic-viewing OTG), and can be attached to laptops/netbook as a portable too. OTG can spoil too, like laptop. but if i bring both netbook and OTG, then i still can save pic even if one of them spoilt or lost. the weight of a 2kg laptop + 500gm charger/cord can still be heavier than a 1kg netbook + 200gm charger/cord + 400gm OTG/charger
- as i said above, my ASUS netbook dun have enough internal storage, so i bring an extra portable HDD. they are light and affordable nowadays.
- if you are tight on weight and willing to compromise on a little safety, netbook + non-OTG portable HDD weighs about 1.5kg (1.0 + 0.2 + 0.3)
- if you ever come across the elecom brand USB cord (mini-B to B), buy it. the cord is less than 15cm long. it won't save much weight, but is less messy to use. many elecom items are made in japan, and they dun fail as often as the made in china accessories which i experience. yes, usb cord can fail.
- protection for OTG and portable HDD? they are usually safe in clothes padded bags. if you kiasu, can consider buying buffalo branded casing (more sturdy, but $$) or get some special padding (peninsula level 2 and shaw tower got some of those camping/travelling shops. they are near cathay and TK, so is quite convinient).
6. cleaning kit
- blower + lenspen
- blower: i use made in japan UN jumbo hurricane (look like
this) as it is light, easy to press and still relatively power. some blower are plain big, or small and weak, or simply so hard to press that your hypothenar muscles (the part of palm at the side of the little finger) will ache after some use.
- lenspen is cheap and good and easy to carry around. cost about $10+
7. camera bag
- ok, bag also weighs although most ppl dun remember this.
- you need one check-in bag and backpack is the way to go.
- next consider, your check-in-bag, daypack, and camera-bag. - can they be the same bag?
- for me, due to multiple lens and fast shooting pattern, i use holster for my camera bag. i've just got black rapid side sling for cam body (not tested for overseas trip yet) and it will probably complimemnt my thinktank unpadded waist belt with 3 pouches for lenses, accessories and a lonely planet if needed (only if flatter versions). i do not use daypack on the go.
- for check-in, i go beach road army market and get the lightest deuter daypack (10-15L).
- i also have an optechusa chest strap which is light enough for a back-up. but just like charger, i won't recommend a backup as the strap is not likely to spoil.
The above is my essentials. the below is what you may consider to bring.
1. flash
- when do you use flash? on the go? do you flash human subjects? do you use flash for night markets or night streets?
- i dunno how to use flash well plus i dun like to flash on strangers, so i dun bring one or when i bring one, i never use it. i find the occasions that i need a flash is so rare and not impt. but it is up to you.
- if you use nikon, how abt the smaller sb400?
2. tripod
- tripod might be more commonly used than flash. but with better ISO nowadays, tripod is more for really night and long exposure, e.g. waterfall, coastal, traffic trails, star trails. and for some, self shooting. but how often would you bring it out is another concern.
- lighter options include gorrilapod, cheap lousy tripods that rattle like a rattle snake, or if you can afford good tripod head and legs. a 1.1kg gitzo leg and a 300+gm markins head sounds great but i'm not going to mention the damage on your wallet. i got a 0.8kg gitzo but find it a little light for tele.
hope this is useful. it is not comprehensive of cos... and to save weight, you got to most imptly consider your needs and be cautious abt it. of cos, $ can save weight too, but how much you will spend really depends. i have personally experience damages and see other with damages, so extra body, extra lens (anyway u may bring more than 1), extra bat, extra sstorage, extra filter/lens cap are not far-fetched considerations.
i'm not sure if insurance is worthwhile considering for your duration. most ppl dun becos of the high cost, hassle and limited returns, but dunno if that is the same for long period of travel.
