For years, the equipment I have always used for assignments work was Canon SLR and DSLR, the latest model I used was Canon 5DMKII, with several L lenses.

Carrying heavy loads of equipment for many years has become an occupational hazard of many photographers. I am no exception. Finding solutions to reduce the weight of equipment was a big challenge. While trying to replace Canon gear with much smaller and lighter cameras, it was also important to maintain image quality at professional level. A few years ago, Sony introduced NEX 7, one of the first mirror-less cameras on the market at that time.  I have tested NEX7 as a backup camera on assignments. It performed perfectly as a backup camera but not as a main. Only when Sony came out full frame A7 and A7R, I was comfortable to switch from Canon to Sony entirely.

Now this is what I bring for a typical assignment work.  

I am a bag freak. I have no idea how many camera bags and backpacks I have accumulated over the years. But finally I have settled with a PacSafe anti-theft backpack that I have recently discovered (even though it's been on market for quite some time) and been using on every single assignment.
