looks like its got some intense processing - ex03 looks sooooo digital. that sharpening and NR look nasty at large magnification - fruit does not look like that IRL.
otherwise, they look nice - i'm sure they'd print great. and at screen size they look fantastic.

Speaking of image 03, I don't agree about the sharpening. I'm not seeing a lot of sharpening there at all.

One nice thing I AM seeing in image 03 is an impressive amount of detail for a JPEG - eg look at the reflective surface of the black cherry from a 100% crop below of the sample image:



you can see the that the image was shot under natural light and was hand-held (you can see the photographer holding the camera), you can see the clouds and trees in the windows, you can see the check pattern of the table cloth etc.

Very good resolution, very useful for cropping etc.

Impressive. Looks like the sharpness is up a notch but it looks very clean and full of detail. I wonder how would it compare to the K-x?

While these shots look very good, they are shot at low ISO. I would expect shots at ISO 200 & 400 to have good DR no matter the camera these days. I want to see how it performs at 3200 & 6400.

Is it just me, or does the shot of the boy look like it's had work done? His skin looks too clean and smooth, almost plasticy. With a 55mm prime set at f11 you should see every detail in his skin.



And also I seem to see some chroma noise in the shadows. Not much, but I would expect it to be pretty much clean at ISO400. Again it may be my old eyes



The flan looks mighty tasty though......

IMHO, the K-x has little to worry about in the clean and full-of-detail department...


100% crop


Even when using something like the kit DAL 55-300, hand-held, at ISO 1250, and with no PP other than simply opening the image up in LR3, the resolution the K-x can deliver is impressive.

The K-r looks to be a great camera, but I don't see much need to upgrade to it from the K-x. The K-5 may be a different matter though...

I agree with you, whoever has the Kx, the Kr is not much of an upgrade for the extra $. Very fine detail there for ISO 1250. How much detail you think you loose using in-camera J peg? I haven't switched to RAW yet but I will eventually.

I shoot DNG+JPG. Often there is no visible difference between the JPG output from the K-x and the DNG's, but as a guide you usually can expect to dig about 10% or more resolution out of a DNG vs a JPG. Especially using something like LR3, at high ISO's. It's quite impressive how much detail LR3 can find in RAW sometimes.

The best apertures of 55 are f/4-5.6. f/11 MUST be plasticy. The resolution drops substantially.

Agreed. All the sample photos are at f11. It gives you extra DOF but at the cost of resolution. None of the lenses used have f11 as a sweet spot.

It seems like whoever does the test shots for Pentax Japan is obsessed with f/11. I remember when all the 645D shots were first released they were at this aperture. Of course with the 645D this makes a bit more sense...

O/T, but in ex01, what's going on with that kid's front teeth? Looks like two tiny teeth between what should be the two front teeth. Miniature false teeth to fill a gap perhaps? I've never seen anything like that.
