But don't forget crops...
I think this is quite possibly one of the most overlooked factors in assessments such as these. One good example of this is with wildlife photography.
Which almost always ends-up being subject to cropping(closing in) as a result of lens limitations.

I agree!
USM belongs in the dark ages.
There are very good sharpening tools now that can sharpen images without haloe's(white and black peaks) and artifacts. So I think that from the angle, the argument simply doesn't work.
Quote: The difference between weak and strong AA filters will never really be visible on anything but gigantic prints. OTOH moire can be visible even at small size...
I also think this is true.
However... in the case of the D7K, I've found ACR/LR to play a diminutive role in moire artifacts. As can be seen here:
ACR 6.3 CROP: NX 2 CROP:
Also, I have replicated the NX2 results with RPP as well(so it's no more special or anything).
The point being, that ACR over-inflates moire by inducing color registration errors where none should exist. Which leads me to say that we may be falsely lead into conclusions where none should exist.
Another good example of this can be seen here: Click image for full size
Which is a good example of what the D7K(with weaker AA filter) looks like when processed with a better RAW processor(RPP). And before jumping-up and pointing out the moire in this image, I'd caution that the Pentax sample(which is JPG) looks somewhat worst than this.
So for me... the argument is not a very strong one in fact.
When this topic initially started(with the first K-5 softness thread), Falk pointed out some pretty convincing moire samples(with the dials). And I was on-board with that. But then... I started experimenting with difference RAW processors and found that the results were not consistent at all, and that it would require more investigating prior to a conclusion.
Anyways, that was probably too long an answer for the actualy comment, but I thought I would share my finding nonetheless.
Quote: I made a
picture this morning with the DA* 50-135mm @f/5.6 and K-5 at ISO 80 on a tripod. I applied LR sharpening. I'm very satisfied with the level of detail produced. You can read the street name far away on a plate that is barely visible on a 24" screen. How much more details do you need to make a picture?
This is quite normal in fact.
I'm reminder when the transition between point and shoot camera's were quite blurred as DSLR became mainstream. At which point we had loads of people making statements like 'I made money with...' or 'I'm perfectly satisfied with...' etc etc. And there's nothing wrong with that. However, I don't think it is appropriate to the issue though.
I don't think anyone is saying the K-5 isn't good enough, or up to the task of doing anything. Mainly because I think the entire arguement exists solely based on the fact that another camera exhibits better than, performance(no more no less). Which is nothing new really. However, in this case, the outstanding issue is that the two camera's in question, are apparently using the same sensor. And I think this perpetuates the issue further than it normally should.
And because of this, I think those who care are either wondering why this discrepancy exists. I know in the case of the Imaging resource samples. There is detail in the D7K that can never be extracted with the K-5 no matter what. This can be visible at 100% and there is no moire issue in sight anywhere in the scene. And though I am not devistated by this(personally), a part of me does sort of feel as though this shouldn't be the case.
