Hey everyone, so as the title says, I'm sold on the A7R II. After the 5D Mark IV was announced, and I've tested it for the last few days, I'm completely underwhelmed. After reading comments from A7RII owners, I decided to start researching. After hours of youtube scouring, I think I've made up my mind and I'm going to switch to the Sony A7R II.
I just have some quick questions that I'm hoping some of you might be able to help me with 
My current setup is a 5D Mark III (I just sold this last week), Sigma 35mm ART, Sigma 85mm, and Canon 70-200mm 2.8L
99% of what I shoot is portraits, and many times it's of kids (ie. uncooperative models, running around, etc.)
Onto the questions 
- Can I get away with using my existing lenses with a metabones adapter? I've read some reports saying metabones is buggy and not reliable, but then I've read others that say the latest metabones adapter lets you use canon lenses as if they were native. This is a huge deal for me, as I can't really afford to lose the money/time selling my existing lenses and finding native alternatives.
- Where is the best place to buy a used Sony A7R II? And what would be a fair price? (obviously this is a bit subjective, but I'd appreciate any feedback)
- I'm worried that I'll pay a premium to buy the A7RII now (possibly even new if I can't find any good used deals) and then Sony will come out with the A7R III in June next year. For all of you recent Sony converts, are you worried about this as well? I'd just hate to lose a bunch upgrading to the A7RIII if it releases in 9 months. Coming from Canon, I'm definitely not used to having to worry about hardware being replaced so quickly. I see that the A7R came out in October 2013, and the A7R II came out in June 2015. So it appears to be a 2 year cycle currently.
I would appreciate any and all feedback
and I'd especially love to hear from any people that switched from Canon recently and your thoughts 
Thanks!
