I'm a part time photographer (seniors, weddings, sports, outdoors). If you want really good pictures, get a DSLR from Nikon or Canon. Full frame preferably. Then get ready to spend a lot of $$$ on lenses.
Here is some of
my work.
Then get ready to spend $$$ on software (Adobe Lightroom and Photoshop), and a new super fast computer to run that software.
Every photo I hand to a client has been touched in Lightroom and/or Photoshop.
My primary camera is a Nikon D3s (released in 2010), and the D700 (2008) - purchased both used. Lens are the 70-200mm f/2.8 VR (~$2,000), the 24-70mm f/2.8 (~$1,600), and 16-35mm f/4G VR (~$1,000). It's an expensive hobby : ) I think i calculated about $10k total in my camera bag (Sshsssssss, don't tell my wife that).
They are big, heavy, pro level camera bodies and lenses. I can shoot 9 frames per second (sports), and in extremely low light (portraits). I have taken them out in the field in my pack. Some of my most recent images from Deer hunting 2016.
Do your research, and get the camera you can afford, and one you can use. Nothing worse than getting a great camera, and never using it. Holler if you have questions. Daubs
