It's a great lens, though in my testing, I found it did have one notable weak spot, but it would only crop up rarely: the lens shows rather strong field curvature when focused close up, when you stop down. So if you're focusing on a flat subject close up, and stop down to f/8, it will actually get softer at the edges as you stop down.

In most real world situations, this is not an issue.

This thread is about the f4 lens....just saying
