Here's a list of cameras, lenses, and some of the accessories I use during my travels and everyday shooting.
Some things I consider when buying gear:
Price. I'm not looking to break the bank which is why I tend to go with third party lenses like Tamron.
Weight and size. I look for something that is relatively light and comfortable enough to walk around with, hike with, and travel with.
Ease of use.
And above all else, quality.
