As a professional photographer, I can get a good photo from pretty much any camera but to get the best shots a photographer need to have the right equipment for the photography they are doing. Here is a list of the camera and lenses I use in 2018, focusing on Nikon F mount.
For anyone not in the know about what the Nikon F mount is, it is the mount that attaches lens to camera.
Camera: Nikon D800
The D800 was a revolutionary camera in 2012 and is still a very good camera in 2018. What made the camera stand out so much was the 36mp sensor, which at the time was unheard of in a DSLR. It wasn't just the 36mp but the whole sensor's performance, giving similar low light performance to the Nikon D700. The D800 isn't the fastest camera, it doesn't have the best autofocus and the video is pretty basic but it is great photography camera.
Tamron 35mm f/1.8
Voigtlander 58mm f/1.4 Nokton
Zeiss 85mm f/1.4 Milvus
Nikon 105mm f/1.4E ED
Nikkor 16-35mm f/4
Nikkor 24-70mm f/2.8G
Nikkor 70-200mm f/2.8G
I have lots of lenses but these are the lenses that are in my camera bag. I am not really a landscape photographer, so you will see a distinct lack of wider lenses, with the 16-35mm f/4 being the only ultra wide I have. Most of the photos I take are portraits, so I have 2 very good portrait lenses and the older Voigtlander 58mm, which is a lovely lens. The 35mm was just a lens I bought to experiment with but I found I used it quite often.
