This is my early impression of shooting the Z7 after a few months in. I was shooting a Sony RX10M4 that I loved but wanted to start shooting serious macro photography. When the Sony A7R3 I was going to buy with the 90mm macro lens got backordered I found this Z7 with the 24-70 lens for around 2500 and jumped on the deal and got a brand new Nikon model and a lens for about 300 less than a generation older Sony without a lens was costing. I was looking at 3600 for an great but outdated dated Sony with a great lens.
I have been shooting almost everything tethered to a 43 inch Acer 4K monitor and the results using this camera to compose and shoot are nothing less than spectacular. The most surprising thing is that I expected the learning curve to be long and difficult and I'm amazed how intuitive and easy the camera is to operate.
I've done most of my shooting so far with the Sigma 105 macro lens. It's exactly what I expected it to be and lived up to all the hype it gets and it was a bargain compared to anything close to it. It's a spectacular lens on a spectacular camera and takes beautiful pictures (that I haven't learned how to show here yet).
Update: I added more lenses. Got a 60mm f/2.8G Micro yesterday, Love it so far. Before that I picked up a Sigma 12-24MM aspherical zoom. I rounded out my lens box with a Nikon 70-300mm 4.5-5.6
I made the move to the Z7 for 2 reasons. I wanted to shoot full frame and I wanted to personally experience leading edge resolution. The only thing I can say is that the combination of this cameras resolution and the crispness and detail of great lenses is producing some amazing photographs when I provide the right composition and light.
I'll add more as I get more experience.
