Go to YouTube and look at some of the videos posted by Omar Gonzales, a professional photographer who provides instruction and information on the Fuji mirrorless cameras, especially the XT-20 and associated lens. Well worth your time.
The Fuji mirrorless system is being used by more pros every day. They are amazing, have numerous support groups and YouTube instructional videos on line and are a hell of a lot lighter than Nikon and Canon SLRs.
Get a Fuji XT series instead. Lighter, great lenses, amazing low light images, many support groups. Many YouTube instructional videos and pounds lighter and smaller (and a whole lot cheaper.)
Fuji XT-20 is remarkable at the price point and handles like a classic SLR. MANY support groups and Facebook groups and YouTube tutorials.
Fuji makes outstanding lightweight mirrorless cameras that produce outstanding photos even in very low light. The X-T20 is VERY popular and there are outstanding YouTube tutorials and several Facebook support groups. Quite few pros have switched to Fuji because of the size and great quality. The Fuji lenses are the best in the business. You should take a look before deciding. I LOVE mine.
I have been a Mac user since the days of the small b&W SE units. I have NEVER been hacked, had a virus or malware infect my Mac. I use a 27" iMac and a MacBook Air. I have had to fight off numerous malware attacks on my Windows 10 machine over the years. Each has their place. Reliability and resale value of Apple products cannot be beaten. I would only consider a Windows machine if the software I wanted was not available for the Mac. I have upgraded hard drives and memory on older Macs over the years. Oh, and did I say they are WAY more intuitive and easy to use?
