Purchased Alpha A73 as a replacement for my Alpha A7 (10) years old, fabulous little work horse.
It would have been 5 stars but for the lack of a fully articulating screen, which is a real shame as the camera is absolutely mind-blowing in every other detail. The image quality is tricky outstanding.
This is relatively new to me. I’ve been a canon dslr user for years but wanted to go mirror less and the canon alternative was out of reach budget wise. Taking a while to get used to the menus and the EV but performance wise I’m really pleased. Smaller form is good too.
I originally owned an A7R III back in 2018 and loved it. However, I allowed my gear obsession to get the better of me, and I switched to a different, newer system.While the latest cameras are technically very impressive, the fact is, stills image quality hit a wall in 2017/18 and so if, like me,...
Great piece of kit that totally improves on the A7RII that I have.
I have recently purchased this camera with the Sony 20mm 1.8 and have had a couple of trips to The Peak District, England to put the camera and lens through its paces. Varied landscape work, lee filters and I cannot find the words to really describe my joy with the quality of build and the superb...
Since getting this camera, I have found huge improvement to the quality of my photographs. So mush easier to resize and edit shots, allowing for high quality outcomes, due to the high number of Pixels. I can, when needed, zoom in and crop without getting pixelisation. Fabulous
I’ve used and owned a canon 760d, 7dmk2, 5d3, 5d4 and Nikon d800s and a d810. This camera somehow picks all the best bits from all my previous cameras and puts it into a robust mirror less format and then throws another load of MP to boot. Simply brilliant
This is an upgrade from my original A7 which was the best digital camera I’ve ever owned. The A7rm3 is a step ahead with a proper facility to stream live content to a PC or phone. Huge benefit with my astrophotography. Love it.
Upgraded from a7rii and really loving the quick and swift operations
