I spend a lot of time telling people how it isn't about the gear - that you can make really excellent images with a minimal amount of stuff. And that remains true.
While rearranging the studio a few weeks ago, I took this shot. This is my basic kit that I use when on location. Usually, I'm using/bringing even less that is what is pictured here.
Out of those six lenses shown, I'm usually only using two lenses on a job, if that; usually the 17-40mm if I'm outside on location, and the 135mm when I'm in the studio doing full length and head shots. The top right lens is the 50mm f/1.8, which is nicknamed the "plastic fantastic" because of it's low low price (+/- $100) and I always keep that lens in my bag as a backup. Even if it's a backup to a backup to a backup, its the best valued lens in the Canon line, and everyone should have that lens in their kit. Even if it isn't used very often. It's the best $100 backup plan there is.
I've been trying to shoot more film with the Hasselblad which is why I have the light meter shown. Using film? Get a light meter. In fact, I stand behind light meters totally, even when using digital. Even when shooting the same types of stuff in the studio. If you meter it, you'll never have to guess.
As far as lighting, I'm usually only using the Sunpak 120j pictured to the left in the image. The other flashes I'll bring if I think I'll be needing some rim light or separation light. Very rarely am I using more than three on a location shoot. Usually I'm just using one.
I recently picked up a new camera body (5D Mk II) so I have two cameras on me at all times for back up purposes just in case. Before that I was using a Digital Rebel XT as a backup.
If you edit that image down and omit stuff I only occasionally use, you'll find that I'm basically using 1 camera, 1 light and one or two lenses.
now go back and look at my location work. 90% of my location work is done with 1 camera, 1 light and one or two lenses. Sometimes no light if I'm going natural.
Sometimes the less you have the better off you are. You stop depending on gear and you start using your brain, which is the most important tool you'll ever need. Remember, it's all about the fundamentals of art; line, tone, texture, shape, etc.
Cameras and lenses and meters and softboxes and all that stuff is great, but if you can take one flash, one camera and one lens and create amazing work, then you are better off than those who depend on all this circuitry and electronics.
Dont' worry about what everyone else is using. Use what you have and rock the planet.
Think of it this way: there are people out there with older cameras and less gadgets than you making images more incredible than anyone I know of. And that is fact.
