If you are looking for a camera for videography then you can buy cannon cameras, they are good in videography and photography too. Also they are budget friendly. :)
If you can manage, go for Mirrorless Cameras as they are trending at present otherwise Nikon has many options starting from point and shoot to SLRs and DLSRs that can also be used for Video Shooting as well.
I am not comfortable with hanging dslr around neck while travelling.lost 2 camera already just to get rid of its weight.
so, a very good camera phone is my option.
