Mounting EF 70-200 f2.8 iii?

I was able to get an EF 70-200 f/2.8 iii in almost brand new condition for around $1k. I am considering either selling it and getting a native lens (possibly a wide angle prime lens or the new Sony 70-200 ii -- though that's very expensive) or reverse mounting it...

I usually shoot with primes on my a7riii which has in some ways skewed my expectations and left me quite disappointed reg the relative sharpness of my new 200-600 G and my old 24-240mm. As a native prime lens user would reverse mounting the Canon ef 70-200 iii have any significant side effects or problems? If I ever get a Teleconverter for the 200-600 it's not going to work on the EF...

I also use a gen 1 A7R multispectrum. Would there be any issues mounting it on the older camera such as weight/mount stress or adapter compatibility?

A few questions for anyone with experience using this lens or mounting EF lenses:

  • How does this lens perform mounted and is it very sharp across all focal lengths?
  • Is the AF accurate and snappy, do eye af and tracking work well?
  • How does the metal build quality, motors, waterproofing, and durability compare with Sonys lighter 70-200's (this thing feels built like a tank)?
  • The lens is currently missing the lens hood and foot. Are there any specific third party alternatives I should consider getting for these?
  • Would getting an ef adapter be worth it given I dont currently have any other ef lenses? If I do keep the lens what EF adapter do you recommend?
