Why rent the E? I thought I made it somewhat clear the g2 should have the better corners.

You first claimed that the problem was "field curvature." When several people pointed out that likely wasn't the case, you "proved" to yourself it was.

So, what are you going to do when you buy the Tamron, go to duplicate your train shot, and come up with pretty much identical results? Because I think there's an excellent chance that's exactly what's going to happen. My guess is that you'll end up spending time and money exchanging copies.

My f4 is sufficiently sharp in the center and I assume the g2 is just as sharp in the center if not more. The E is definitely sharper in the center than the G2 but that's not my problem, it's the corner.

I take it you are drawing these conclusions from online tests, since you haven't used either lens yet. Well, those same online tests showed that the 70-200mm f/4 did not suffer from field curvature at 200mm, and yet you "proved" otherwise. So why trust them now?

I get that "seeing is believing," and that it's your gear, your money, your time and your choice. But I suggested renting the "E" so you know what you what is and isn't reasonable to expect.

How was it not likely field curvature? The center of the hill at that distance was clearly sharper and I know the lens has the capability to be sharper in the corners.

I haven't used either the E or G2, that's why I am asking. There are multiple reviews that mention field curvature for the 70-200 f4. I am not looking for no field curvature I am looking for less forward curvature, I don't need it to be perfect with zero curvature just less curvature to the front.

I think the point here is that, because none of us can really see the "problem" as you're seeing it, there's no way that any of us can advise whether the Nikkor E or Tamron G2 might produce a result that you're happier with. As Michael says, the only way you'll be sure is by trying one or both of them for yourself in the conditions that you'd be shooting in.

Sorry, but I fear that's the best we can do.

Well, I just replied to myself a minute ago. Go to the reply labeled "Another opinion" It appears some other people have noticed the problem, if that detail helps you. I'm going to search for people complaining about that issue, the quantity of results I find should give me a good clue.
