Own XT3-Won an a73. Keep or sell?

[DangerTF]

Hello everyone. This is my first post so i’d Like to introduce myself to the forum.

so here is my situation. I own an XT3 and really like it. I’ve got the 14mm, 35mm f2, 18-55mm, 55-200mm and the MCEX11. I feel like it’s a pretty decent kit right now.

I recently won a Sony a73 w/ 28-70mm as a prize ($0 spent totally free) so I was really excited. I have not used the Sony at all. Brand new no shutter actuations so it’s pretty much worth open box price to the right buyer.

my dilemma is should I keep it as an awesome second camera, being full frame and great auto focus for stills. Or sell it and put the $ towards more Fuji lenses? I’ve really been thinking about the 100-400mm with the 1.4 teleconverter to expand my wildlife opportunities.

Always having a backup camera is nice and full frame as an option doesn’t hurt. But it’s a totally different ecosystem.

thoughts?
