I have friends who go on extended travel lugging their big bag of photo gear, usually a DSLR and two or three zoom lenses. Don't laugh, I use to be like them because 5 years ago DSLR give you the best performance; that was before, how about now?
During our last gathering, my DSLR die hard friends were shocked when I told them I only took my little Lumix GM1 when we went to Malaysia and Taiwan this year!
They all sneered at the small wonder, to them, nothing but their HEAVY DSLR can give them the travel pictures they are proud of!
Mind you, as you can see from the picture above, I still have my DSLR; a Nikon D300 that I bought 5 years ago. The zoom lens attaches to this once the Camera Of The Year, a Nikon 12-24mm f/4 AF-S DX , this Nikon has an equivalent field of view of an 18-36mm lens.
When you are on a shoot-n-run travel, to me, this is the best lens to have on your DSLR!
On the left of the heavy weight D300 is my feather weight Lumix GM1 with the
Panasonic 7-14mm f/4 ASPH LUMIX G VARIO ultra wide zoom. This incredible optics behave like a 14-28 mm equivalent!
