Hi
Not sure what I am doing here is appropriate and in the spirit of the thread.
Also not sure, is it a K-II or IIs image but which ever it is there is still lots of detail that can be had with very minimal PP. I agree with gazong, if it is the K-II than this is all I will ever need. And if it was the K-IIs I don't think it is that fantastic. (I think more and more it was taken with the K-II)

I would probably save myself the extra $$$ and give the IIs a miss because if for any reason I really really need an extra sharp pic, I know I can do that in PP.

Used Viveza to lower brightness a bit (on this part of the pic) and increased structure a little and finally sharpened it in FocalBlade. (Medium).

Greetings

FWIW, I wrote a small article on the "Pros and Cons of Omitting an AA-filter".

...Also not sure, is it a K-II or IIs image

And again: it definitly was that camera shown some posts above, the K5 IIs.
Still belongs to Pentax Germany, Hamburg.

Another interesting shot in the dark by Evil Homer testing K5 II(s)' AF

I'll try to translate:

"... So the AF works still, even if you hardly see something in the viewer.
I found it very impressive!

Here's a picture with ISO12800(!) at f1.8 1/15 sec so can you imagine: it was a bit darker.

Pointing to the little plate on the head - the K5IIs focused sharply.
It took a little longer - but of course she did."


btw: Evil Homer uses a Canon 5D MkII.

He concluded (via PN):
"The K5 IIs is the best APS-C Body on the market".

Couldn't see the photo Keiner uploaded, but judging from those words, I think yeah, enough has been said. )

The photo shows near dark in the dark

I upped it somewhere else.
I can see it. You too?

[Quicksand]

I can see both copies. Not bad.

My pictures at ISO 6400, 1/30s, F1.4 was already approximately -1EV.

ISO 12800, 1/15s, F1.8 is about 1 stop faster in ISO, 1 stop faster in shutter speed, and half stop slower in aperture - meaning -3EV sounds about right. And if it took a little while, but locked nicely, that's fantastic.

Thanks! I can see it now. Looks like that tripod was in a really dark place
Further proof of the -3EV sensitivity that works. I've experienced its effectiveness too, pointing at near-black shadows during the testing time we had at a recent Pentax event in Manila. Couldn't see anything in the VF, but it locked, without hesitation, at something. It wasn't on my card though... I'll try contacting my friend who has it. Hopefully even with just 11 AF points, Pentax did the accuracy right this time!

Your parameters correspond to 0 EV and the tripod shot parameters correspond to -1.4EV.

However, equating shooting parameters with the brightness of a scene only works if the exposure works out to be 18% gray level. The latter is rarely the case so brightness values based on shooting parameters should always be taken with a big grain of salt.

It works, but we don't know if it's accurate or not...

Looks pretty accurate to me. The photo was taken at f1.8, a point where the K5 classics would have struggled locking and been all over the place with accuracy.

If so, I stand corrected - I only go by what PhotoME tells me on my metering matrix.

I hope Adam/deadwolfbones has a production copy by now so we can expect more in-depth tests to prove how accurate the -3EV AF is.

Now i'm tempted to put up the Engineering copy =).................(RAW)
