I was hoping for some insight from automotive photographers who have switched from Canon/Nikon to Sony as their primary camera. I don't have any spare cash to add, so I'd need to sell my Nikon gear and get an equivalent Sony compatible.
Some background: I do am mixture of private paid shoots and editorial work (for build features) along with some motorsport event and meet coverage too. A lot of my shoots are strobed, or lightpainted, so dynamic range and low-light ability is fairly important. Currently I have the D800, with 16-35mm for rig shots/engine bay, 24-70mm for general and 70-200mm for motorsport and occasional non-moving car shots too. I love my current setup, but it's just so heavy that fatigue is a real issue.
Over here in Australia I can get approximately $2200 for the D800, $1200 for the 24-70mm and $1200 for the 70-200mm giving me $4600 to play with.
So far I have ruled out the A7S; I need more resolution for my private clients despite the amazing low-light performance. I can't afford the A7RII. So this leaves me with the A7R, and A7II as potential choices.
What lenses are out there that will cover my needs? I use all of my lenses, all the time, so I can't really only buy some, with a view to saving for the rest in the coming months, it needs to be a complete switch out.
Thanks in advance!
