Great entry for the novice photographer

I've always been a photography hobbyist. I have had multiple different compact digital cameras and smart phone devices that have suited my needs, but as I have gotten more and more into photography, I felt like I was ready for something more advanced. Enter the A7 III... After doing some extensive research, I decided that this was the best fit. The Sony A7 III gave me a great entry point on price since it is an older model, but it still has all of the features that I will need for a while. The image quality has been great, the manual settings allow you to learn and experiment, and it has great headroom to let you grow into it for a long time. I have only just started, but I can already say that the Sony A7 III has made the transition very easy.

Workhorse

This full frame camera really captures a whole range of color and a wide composition. Micro 4/3 are great, but this full-frame creates a whole new ball game. The Sony e-mount allows for third-party lenses if you would like to add them. All in all a great camera.
