I’ve included my most used and carried photography gear in this list and pictured. Out of the four lenses I carry, they can probably be ranked in the following order (number 1 being the most used)
1) Nikkor 14-24mm f2.8
2) Nikkor 50mm f1.4
3) Nikkor 24-70mm f2.8
4) Nikkor 70-200mm f2.8
However most of the pictures I publish online come from the 14-24mm and 24-70mm. The 50mm is awesome for cameo work and I favour the 50mm and 70-200mm for portraiture and creative work.
I find that with the Nikkor 14-24mm F2.8 I’m usually using it at the 14mm or 24mm end and don’t tend to use the middle range as much. If I could change anything for architectural work I’d love a tilt and shift. Unfortunately Nikon only does a 24mm at the wide end whereas Canon does a 24mm and a 16mm – which makes me really jealous! But then I know Canon users are envious of my 14-24mm so I guess things are even.
I have noticed that Canon lenses are generally shorter and lighter than the Nikon equivalents which make them more efficient for packing and carrying. However, whilst I’m fit enough to carry this bag I’m not planning on changing anytime soon and if I was after fast and light I’d really consider a micro 2/3rds solution such as the Olympus OMD E M5.

You may also notice that I have an L-bracket on my D800. This is by Really Right Stuff and is permanently attached to my camera as it makes shifting between landscape and portrait orientations really fast and easy. It is a pain to access the ports though as you need a toothpick or thin screwdriver/knife to poke it open. I used to have the L-plate further away from the camera to leave space to open and close the flap easily but found that it increases the width of the D800 making it more tricky to pack in my F-StopGear ICU’s (review coming soon).
