I hope that K-5 will have same battery and battery grip as K-7

Don't take my AF points schema for anything more than a guess.
Making the wrong addition actually made me think about two possible solutions: one with 19 points as posted before and one with 18 points made with a double center point sensor (one for high aperture lenses):

I'm the one that made the guess on dpr and, yes, it was to early in the morning to do the math right.
Anyway I found a way to put 18 sensors in a workable way, I think. It could be that in the center they put two sensors, an additional one for high aperture lenses.

Let me count them again......yes they are 18!

In my view an AF sensor for high aperture lenses is more important than a higher number of points.
I use the center point in 99% of the time anyway.

EDIT: Wow, this is my 1000. post!

Didn't realise you lurked here as well. Hope you didn't mind my copying your AF sensor layout?

• Complete new AF system superior algorithms.
• 18-point wide autofocus system (SAFOX IX+)
Of course, the nice thing about a wide autofocus system is, IMHO, that it can be used as-is in a FF body. If it was the same arrangement and size as in the K-7 then a FF model would have the problem that the AF points would be concentrated too much in the center. So we have a wide AF in the K-5 and a normal AF point arrangement in the upcoming FF model?

The 18 point AF could be a deliberate red herring to track leaks.

Well, I am in. I am on a K20, so I had already talked myself into the idea that I would skip the K-7 and go for the next flagship model. I wanted three things - better ISO performance, more AF points, and a higher fps (I shoot the hockey team my husband coaches). It looks like I am getting my wish! Now I just wish they would hurry up and announce it so I can get my preorder in.
+1 for everything Allison said (except the hockey team bits )

Yes, and not just that.

The K-5 image seems to be authentic. At least, it was said on a German forum that it was online for a couple of hours on the Pentax Hamburg website

• 18-point wide autofocus system (SAFOX IX+)
• ISO standard : 200-12800
• Expanded ISO : 50 - 25,600
• Hybrid VF utilizing translucent LCD to display focus points and framing grid.
18/19 AF points. Well, if you add up an uneven number of rows with any number of points each where just the center row must have an uneven number of points, then the sum is uneven. Always.

So, the only way to have a center point and an even number (if 19 results from 18 with counting the center twice) is something else than a matrix. Even a sparse matrix where positions are left out (but in a symmetrical way) is impossible. But, why should it be a matrix? The simplest way to get 18 points is 1 point in the center and 7 points in a full circle around and then 5 points in two half circles each to fill the sides. Unlikely but not impossible. It's more likely 19 and the center not counted twice. OTOH, 19=5+9+5 which is strange again.

ISO50. Any ISO below base ISO is implemented by a smaller gain but it doesn't prevent the well to flow over. Normally, the full well capacity is sufficient for something like ISO150 and so ISO200 becomes the base ISO with ISO100 as an extended option which has more risk for blown out highlights. ISO50 then is nothing but overexposure. It can easily be activated in firmware but doesn't make sense. Nevertheless, we don't know what marketing decides these days...

Hybrid VF. That one seems worth a second look. It may not be from a Pentax press text. Because the effort of a translucent LCD (which for frame lines would have to cover the full frame making it an expensive option) is a waste for displaying grid lines. You rather would expect live histogram (from the 77 fields) or other stuff. Except if the translucent LCD isn't matrix type but one with predefined display symbols like in a LCD wall clock or weather station. Which makes it a less desirable thing though. OTOH, optional grid lines via an overlay display is a D300s feature the camera the K-5 most likely tries to copy as close as possible. So, while they had to replace the VF overlay display, they may have added the Nikon-style grid lines and missed the opportunity to have a full matrix overlay, possibly even offering life view thru the VF. That's a pitty for a flagship model.
