Hi all, I'm here again with a buy question: lots of online reviews state that the 85mm f1.8 is nearly identical to the f1.2 II in terms of image quality when stopped down to f2. It even focuses faster than the L version. All that the f1.2 version has going for it seems to be that it is very sharp wide open, and has slightly better sharpness and contract than the f1.8 version. Again, money is not an issue here. Is the f1.2 II worth my money with nearly identical visuals and even slower focus, to be offset with f1.2 for low light conditions? Let me know your real-world thoughts! Thanks!
Before buying any lens, rent one first.
Unless it is difficult to do so where you are, I see no reason to buy one before renting (unless you have the current version or very similar one).
You didn't specify what you need the lens for.
The good news is that you did already the good first step, by reading the internet. Now, go and rent each one of the three in order to see for yourself (including the 70-200), then ask questions. You will be able to determine the right answer from wrong, based on your personality and need.
Don't forget, specialized lenses dictate a lot on your photography style.
The 1.2 is not for everybody. It is my go to lens and I see no other lens that can replace it in my bag for now.
I never had it alone, though. I always have a general purpose lens with it.
