Resolution, noise and sensitivity

As our resolution test images show, the Pentax K-7 is capable of resolving an impressively high level of detail, especially in raw files at the lower sensitivity settings. Simultaneously captured JPEG files are also good.

Kit lenses are rarely perfect, but I was both surprised and disappointed to find that our sample of the new weather-resistant smc Pentax-DA 18-55mm 
f/3.5-5.6 AL WR lens resulted in images that are noticeably softer than the smc Pentax-DA 18-55mm f/3.5-5.6 AL II 
optic supplied with the K20D kit. The corners are especially poor and suffer from astigmatism.

Most of my JPEG files benefit from an application of Unsharp Mask, but it cannot resolve the problem of blurring of detail towards the edges of the image. Several of my images have the main subject towards the edge of the frame and they are disappointingly soft.

Noise makes an early appearance in images from the K-7. High-sensitivity images have a lot of chroma noise, but the raw files are sharp. As usual, JPEG files are softer and a little smudgy when the high-sensitivity noise-reduction system is in its default medium setting.

I prefer the sharper, grittier results when no in-camera noise reduction is applied. The noise is fairly evenly distributed and banding isn’t a major issue. I particularly like the images produced with the camera set to its highest expanded sensitivity setting of ISO 6400 when shooting monochrome images.

These images above show sections of images of a resolution chart, still-life scene and a grey card. We show 
the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the 
better the camera’s detail resolution is 
at the specified sensitivity setting

    Sorry but I disagree with the whole coecnpt of women in combat, the same as in the cops. Ken, Grams & I saw you blow thru the obstacle course. The women were allowed to run around the cinderblock fence and avoid any other parts that were like the tire jumping part. Legs were too short. Also, they must be given Days off when they are PMSing or some other female peculiar ailment. I doubt the Iraqis are carrying around MIDAL just in case . They demand equality then yell for special treatament because I am a woman and can’t deal with it.Be really fair, democratic etc . let Nancy Pelosi & Harry Reid lead the first charge and develop a draft for women . You would see how quickly the baby must have its mother’s milk pumping. Just out of bullet range and heaven help the Major who ordered the Mom to hang the baby in her backpack ready for next feeding.. If they want to fight, neuter them first.I have a REAL problem with minorities getting promoted ahead of better qualified and deserving to pay the quoto debt.Don’t get me started. We have lost a lot of excellent men in our peacekeeping effort for no real good reason. Should have sent some whiney women instread.
