I am sitting on the fence about this lens. I was hoping for a fast 85 or 135 to be announced and that hasn't happened. I have the 35 and 55 for my A7r and like them both but use the 55 80% of the time. I bought a Sony 85 2.8 with an adapter to hold me over and while the image quality is excellent in the studio it struggles with focus and even worse will not let me use my Spider Holster when I am on a planned outdoor shoot.
I would like a native lens longer than my 55 but I am not thrilled with carrying a larger zoom rather than a prime. Any opinions out there? Do you love it - would buy it again - never leaves your camera - or it's just a lens.
