I used to have one of these and they are a lot lighter in weight than the Pentax equivalent.

#1 is reasonably sharp considering the aperture was wide open but I think #2 & #3 have suffered a bit having to shoot through whatever barrier was between you and the cats.

Not quite Ken. I think you have to hold the Menu button in when powering the camera on.

The instructions specific to your camera should be contained within a readme.txt file which is in the zipped file you downloaded.

I think that there are several factors influencing the lack of sharpness in this image.

1: The shutter speed is too slow at 1/200th for a 300mm lens.
2: The aperture is too wide making any available DOF very small.
3: The available light didn't allow the use of more appropriate figures for 1 & 2 above and excessively high ISO (though we don't yet know what was used) on the K7 introduces noise.
4: The eyes are not in the plane of focus.
5: The image is cropped, perhaps a bit too much.

There appears to be some odd green artefacts in the background and unfortunately, your subject is not sharp.

Repairing these cameras is a lot easier when you have a service/repair/spares manual.
Password to all manuals is "Pentax" and is case sensitive.

Funny how real life use doesn't mirror these findings. I use quite a few of the 'turkey' from 7DayShop and I have nothing but praise for them. I use them in torches, clocks, alarms, cameras and flashes and I certainly have no complaints about their capacity or life.

Congratulations to Dan and the baby's mother. Hope all goes well.

Does she come with a two year warranty?

There is a simple answer to this, if you have lenses that duplicate focal lengths, keep the best, sell the rest.

Damn, I thought my LBA was cured.

Is the 150-500mm really the OS version Chris? The lens at this price on your site is the non-OS version, the OS lens is priced at £749.99.
