Pentax K-x vs. Pentax K-r

goodpics · 10-31-2010, 06:27 AM

Goodpics say hello to the pentaxforums. I like Pentax because it`s not canikon normally (

). At the moment we have K-x, K-r, K-7 and soon one K-5.

Here is the compare about the new Autofocus Savox IV+ (Pentax K-r) and the Autofocus Savox III (Pentax K-x, white):

You Tube

And here the new Live View, he works really great:

Pentax produce a gread new camera with more speed in Autofocus and Live View.

thanks goodpics for videos.

It seems k-r's LV (contrast based) autofocus is much improved, while the with FV (dedicated sensor) performance is similar (?).

Adam · 10-31-2010, 08:07 AM

The k-r has safox IX, not IX+. The plus denotes a light wavelength sensor, which is found in the 645D and the K-5. Nevertheless, seems the new af is much more accurate, and faster!

@ Adam:

12,4 Megapixel CMOS
Empfindlichkeit bis ISO 25600
Bildfrequenz 6 B/Sek.
SAFOX IX+
Duale Stromversorgung LiION Akku oder 4x Mignon
HDR Automatik

(everything from pentax.de)

Where you read about the Safox with no "+"?

Pentax now what is really inside, or it is simply a mistake on the european homepages. I don`t think that the camera is other here in europe.

I agree, the K-r focus system is not +, because it doesn't have the tungsten AF module.

Regarding the video, I would just like to point out that it's much easier to autofocus on a white camera with black trim than it is to AF on a black camera with black trim. Also, some of the time the focus confirmation was on the floor, not the subject. Better targets would have made for a better test.

I now what you mean about the black/white, and the focus from the K-r was at most on the black scroller from the K-x. The test is really not perfectly, but the difference between the autofocus is to see.

RolloR · 11-01-2010, 06:27 AM

i don't care so much about the phase detect AF difference, they have always been pretty fast for my needs, but WOW at the LiveView focus!

melander · 11-01-2010, 06:27 AM

Nice, alot less k-k-krrrr-k-k from the k-r

opiedog · 11-01-2010, 06:53 AM

hard to nail down the differences in phase detect since pointing the cameras to the same locations were not so consistent.

i don't seem much difference in phase detect, but still a bit better than the kx

Yup, it's a typo, just like the "DA L" designation for the 35mm on the Pentax USA website. Apparently the different Pentax branches can't reach an agreement on what to name their products

I have send an email to pentax germany and i tell you what is the answer.

goodpics · 11-03-2010, 02:02 PM

Ok, pentax say that only the K5 & 645D have this sensor. The K-r is without, but on the homepage it is still wrong...
