I have one that I picked up on Amazon for £210 used like new, turned up in original opened box box with all internal contents and lens all wrapped as brand new. Its a good lens, the Sony is probably a little lighter, possibly focus slightly quicker than this but its not double, nearly treble the price better. Certainly not to me mind. I have used it with an A7ii and updated to latest firmware (may 2020 iirc) and its works fine. I took this shot today while out walking the dog, worth noting I was hand holding this with one hand to take the shot as I had his lead in the other.
I would recommend it, especially at the £200-£300 mark. I havent done back to back testing in the same environment with both lens so I won't say one is better than the other based on anything scientific. I will say its a well made lens, very quiet to, though a little heavy but nothing I really worry about. I hope this helps.
