Nice Anders,

Mark, you continue to have serious problems with your reading comprehension, as exemplified (once again) below.

When someone whether the 20mm f1.7 AFs fast enough, you state yes.

No, I tell them what I already told them, for example here:

When someone asks whether the 20mm f1.7 AFs as fast as the 17mm, you state yes, UNDER general conditions.

No, I tell them what I already told them, for example here:

So great; you win. Just don't go about commenting that you don't feel there's an issue with the AF of the 20mm f1.7 when others clearly feel so.

I am not telling anyone that. I am telling them what I already told them, for example here:

Oh wait, you need to have 'controlled' tests as a basis of confirmation. Or else whoever states such a claim is speaking ballyhoo and your 'controlled' tests should be more accurate.

You are obviously speaking ballyhoo, time and again, as everyone can readily see.

Even though you are already stating under YOUR needed conditions it works.

Exactly. And I am telling others precisely what those conditions are so that they can decide for themselves whether those conditions apply to them as well or not.

Or when you haven't had a chance to try out the 17mm f1.8.

I note that you dodged my question about the way the 17/1.8 compares to the 12/2 and the 45/1.8 a second time so I simply rest my case.

And FYI, I have had the 17mm f1.8 and the 20mm f1.7 hand in hand. And so unlike you, I am pretty sure which one focuses faster.

We are both sure that the 17/1.8 focuses faster under some conditions.

Clearly under ALL conditions.

Where's your evidence and where's your answer to the question you have dodged twice?

THEN I sold it.

Feel free to sell and buy what you like.

Oh wait, YOU need evidence. So I should go and record the whole process.

Yes, evidence is important for those who want to make rational decisions. You are clearly not among them though.

Do expand your test environments.

No need for that based on anything you have to say.
