Most travellers try and save on packing heavy and bulky items. while on our latest trip we have lost count of the times we see 'obvious tourists' carrying heavy DSLR cameras ( and even spare lens) while trying to negotiate an overcrowded location. Or better still they lug their heavy camera gear to the museum/castle etc only to find that when they get there they find a 'no photographs allowed' sign.
Forget the grief, pack light and enjoy your holiday.
At the risk of upsetting DSLR owners ( I have two of them myself, they get left at home) one word of advice for anyone thinking of buying a camera for travelling, forget the DSLR. ( or any large camera) unless you are a professional photographer etc ( I am guessing thats not generally the case) then a small good quality camera is more than sufficient.
Who is going to look at your photos you take ( be honest, really honest!) and be that interested anyway.
Are you going to enlarge/print them so big that they require super high quality, that you 'might' get from a DSLR?
MY BEST PIECE OF TRAVEL EQUIPMENT
As an alternative to my heavy DSLR, over three years ago I bought a Canon S series compact camera ( S100 model, I believe the latest model is an S120). it has now over 6 months of solid travelling use.
Thus far it has taken many hours of video, over 12,000 photos and still going strong. The S series 'must' have been made for travelling.
Pros
It easily fits in your pocket ( my front jeans pocket) so its not obvious I am carrying a camera and can be used quickly, when needed. and it easily protected from rain and dust etc. ( most other 'compact' cameras are still too big to EASILY fit in your pocket and don't always have wide angle)
It can operate in very low light ( often with no flash) takes very good video, shoots RAW files, if required.
It has a very wide angle for landscapes etc, and 'selfies' are easy. Telephoto is very, very overrated IMO.
Inexpensive, given the quality and features. Can be bought in Australia for approx $350 AUD. so not that expensive if it gets damaged or stolen etc.
Weighs very little and is fully featured. ( they get good reviews, particularly for their price)
Cons.
battery life is not great but a small spare battery is easy to carry for long days of shooting many photos/video.
Not all camera stores stock the 'S' series.
So if you are thinking of taking a large camera, think again. enjoy your holiday instead.
