Photography isn't all about taking pictures.  Photo-gear is fun to research, work and save for, and become experts at using.  I've put together a resource for helping to research camera bodies, lenses, and other auxiliary equipment related to photography.  Unfortunately, I haven't used all of what is included here, but I can most likely point you to credible resources for finding the answers you are looking for.  And, if you decide to purchase online, I would ask that you click on the links on the sidebar.  The item you are considering costs the same either way, but I received a small % for helping you with your decision.  I would love to hear what gear you purchase and how like it in the comments section!

Cameras / Bodies

Camera bodies come on all sizes and shapes these days.  There are a few categories that should consider:  Full Frame, APS-C, Mirror-less, Micro 4/3, and compact.  The major difference between these categories is the sensor size.  (see here for sensor size comparisons)  

The major camera body manufactures today include: Nikon, Canon, & the increasingly competitive Sony.  There are many other manufacturers who specialize in certain markets but most professionals are most likely shooting with one of the "big three."  The resolution in camera's today is better than any time in history.  Even many compact cameras can product exceptional images.  However, there is still no comparison to a quality camera body and a premium lens.  However, mirror-less cameras are making a big impact with comparable performance at a fraction of the size and weight.

If your looking for a new camera or camera body, it's worth asking yourself the following questions: 

1)  What type of photography are you doing?  (i.e. professional, amateur, family photos, etc.)

2)  What is your price range?  (cameras and bodies (no lens) can range from $100-$6000 and higher)

3)  Do you shoot in manual, aperture priority, shutter priority, or prefer auto mode?

4)  Do you want interchangeable lenses or a fixed lens on the camera?

5)  Is zoom important to you?  Or, would a wide angle (say 28mm) suit most of your needs?

Once you've answered these questions, check out this link and input the search criteria.  Every camera line has a consumer level, mid-range, and pro-level camera (or body).
