Odd request, but can I get a heat check on a D800 in 2019? Lol.
I ask because I have one but ever since I got my X-H1, I've been considering on selling my D800.
I don't even use the D800 as much anymore. I shot an event with it a few months ago but other than that, it's been sitting in the bag at home while I take my X-H1 everywhere with me and exclusively use it for my day job.
But I took the D800 with me last weekend for fun and imo, it still is fantastic despite it's shortcomings,(no 4K video, 4fps burst, heavy af) that I'm starting to think it would be a ridiculously dumb move for me to sell it lol. Like I can probably sell my entire Nikon kit and pick up an a7III, X-T30/X-T3, X-A7, whatever FF/APS-C MILC with 4K video, but getting something other than the Z7 or a7r line feels like a downgrade and it'd just sit in my bag until I need it again(or my X-H1 gets relegated to backup duties). :\
Considering upgrading from my X100s and finding it hard to decide between the X-H1 and X-T3. The former has the body stabilisation which actually looks incredible, but the size is nearing SLRs which I was happy to leave behind. The T3 has all the video and autofocus improvements and a great form factor (but no IBIS!)
As an X-H1 owner and somebody who also has a goliath DSLR, I will say that the X-H1 just looks hefty, but it really isn't. I've traveled a lot with my X-H1 and it still isn't really an issue.
IMO, it comes down to how you use a camera. If you have a bunch of lenses you'd want to adapt to Fuji then the X-H1 is the best choice. But if you absolutely need the hardcore video capabilities then the X-T3 is it. Personally tho, I think the X-H1 is the better choice out of the two as it strikes a good balance of value, features and usability. Either way, I don't think you'd go wrong with the X-H1 or X-T3... just set that thing to Classic Chrome and don't even mess with your settings... I literally have been shooting on CC for like months now and it's just downright gorgeous lol.
