All to often do we fall into an activity, that we get so caught up in things that aren't so important that we forget why we got into the activity in the first place. In terms of photography, this could mean that a photography acquires G.A.S. (Gear Acquisition Syndrome).
I have to admit that I myself have acquired this. In the recent months, I've been caught up in acquiring new and old lenses, just to try them out and to have the best lens for every situation. The problem with this is that I ended up with a bunch of lenses that I have to drag around and a hole in my wallet.
When you have a lot of options to choose from, you often don't know what to choose. When I travel and visit new locations, I often don't know what to expect and would have to carry as much gear as possible. This just causes more physical strain, takes away time as more time is needed to set up, and just reduces my productivity over all.
I recently saw a post about this subject and it was suggested that the reader should stick to a single focal length/lens. I decided on using my 35mm lens as this was the one that I started on. The 35mm really forces you to work for the shot. It's more on the wider side of the spectrum so you have to interact with your environment and subject.
Of course for someone who is a working photographer, this may not be the wisest decision. I'll be shooting a wedding in a few weeks and I will not be limiting myself to just the 35mm. This would be careless and not fare to the bride and groom. If I limited myself to just one lens, I believe that there is a great probability that I will miss a lot of important shots. Other than in paid situations, I will be sticking to my 35mm.
If you yourself are struck with G.A.S., I would highly recommend trying to use just one lens (preferably a prime) for an extended amount of time. See what you can do with what you have and explore your creativity.
