Originally posted by Adam Review aside, all of your comments seem to be trying to prove that the K-5 IIs is no better than the K-5 when it comes to sharpness.
I'm not trying to prove that. It would be a foolish attempt because the K-5 IIs can be superiour (as I've
said before).
The reason why I'm posting "hold the horses" messages is because I
- don't like unfair comparisons, and
- don't want the K-5 IIs to cause disappointment. Even though moiré and other artefacts are rare, they can appear and cause frustration.
Not capture-sharpening images from a camera with an AA-filter is like not boosting the exposure for an image that has been captured with dynamic highlight protection. When the camera purposefully underexposes to protect highlights during capture, the post-processing must pull up the exposure to undo that effect.
Likewise, an AA-filter purposefully introduces blur to prevent detail from reaching the sensor during the capture that the sensor is not capable of recording. Accordingly, the post-processing must undo this blurring. Hence, the need for capture-sharpening.
The K-5 IIs images must not be capture-sharpened at the same level, because no prior blurring has occurred.
Originally posted by Adam The K-5 Iis does have superior resolution, as can be evidenced through something as simple as a snapshot of two distant objects.
What you are seeing is
- better micro-contrast from the K-5 IIs because you don't capture-sharpen the K-5 images, and/or
- focusing issues with the K-5.
You cannot claim better
resolution if you are only referring to
sharper looking images.
If I sharpen a K-5 image, it will look much like a K-5 IIs image, but I won't have increased resolution, i.e., the ability to resolve fine detail.
If you can post an example where the K-5 IIs captures a detail that cannot be made visible by appropriate capture-sharpening of an equivalent K-5 image, then you have demonstrated a resolution advantage.
Originally posted by Adam The test charts can be misleading in a way, as you benefit more from the K-5 IIs's filterless design at long range than at short range.
This statement suggests to me that your K-5/lens combination indeed has an issue with focus near infinity.
It would be really worthwhile looking into this and validate the micro-AF-adjustments.
Why would the absence of an AA-filter have a greater effect if the subject is further away? All that matters is the image that is projected on the sensor, not how far away the original scene is.
The only thing that I can image to change with subject distance are incident angles on the sensor. However,
- I do not suspect the FA 85/1.4 to have an issue for the examples shown, and
- I don't see how the absence/presence of an AA-filter would mean that different incident angles map to different levels of sharpness.
P.S.: Even when you provide a level playing field for the K-5 and K-5 IIs, you could still argue that the latter is superiour in many cases because the required capture-sharpening for the K-5 (that can be omitted for the K-5 IIs) can introduce additional noise. One may have to adjust the threshold parameter when using an unsharp mask, for instance, in order to make sure that the sharpening does not introduce grain where it would be visually unappealing.
Also, I'd love to be able to turn off sharpening in LR altogether, because LR performance is much better if you can switch off the detail panel completely.
