I normally do not plan to take photos. If I am in shooting mood, I take my camera with me. I cannot predict or plan the types of photos that I am interested to take. When I go out, I take the camera and a lens cleaner, sometime an additional lens and a backup battery. I want to be able to carry my camera all the time while walking, so by definition I cannot travel heavy.
- Canon EOS 5D Mark II
- Panasonic Lumix DMC-LX3
- Canon EOS 20D (before 2009)
I use the second one if I want to stay invisible and portable.
- Sigma 12-24mm f/4.5-5.6 EX Aspherical DG HSM
- Canon EF 24-105mm f/4 L IS USM
- Canon EF 70-200mm f/4.0 L IS USM
- Canon EF 100mm f/2.8 USM Macro
Are there many options out there? probably yes. I use Adobe Lightroom for almost the whole process cycle. I have it to catalog all my photos on physical hard drive, import recently taken photos from camera, post process and retouching, and various exports.
