So, I run a photography business - just figure skating. Well, it is a niche market and works well for me. My go to camera is typically a D500 (i have 2, 1 for backup). But for some events, I use my D5. Well, a few months ago I was doing a team event with 2 photographers at ice level. One lady (amazing photographer) has a D3s - so I give her my D5 to use. My other photographer has a D4 - about the same IQ. No worries... but, this summer the FAA gods got to him and his flight was delayed. No worries, I have a couple D3s cameras... holy DSLR... the IQ between a D3s and D5 is severe! So, I need a backup... I looked at the 'Z' series but the battery life was, well not acceptable for what I do. So D850... today I started looking... hmmmm... a sign from the Big guy? D850, $500 of and includes a grip.... only until midnight tonight? (so it says). Guess I have that now to add to my stable.... I hope it works for what I do. Anyone use for sports?
