100% output every time. You'll need to use the camera on manual and set the aperture for correct exposure.

The AF140C is a TTL flash but the K10/20D does not support TTL. It actually works very well with the K10/20D bodies in manual.

Only the *istD and *istDS Pentax digital bodies fully support TTL flash.

I bought this from a forum member (now defected to Nikon, but still visits occasionally) some time ago and have not used it enough to warrant keeping it. I've since built my own twin flash rig for macro work and this is now surplus to my needs.

It is complete, in exceptionally good condition, battery compartment is pristine, all 3 lens adapters are present (49, 52, 58mm), as is the manual. It has its original foam lined box and the original cardboard packaging.

Price to be discussed privately.

PM if interested.

How do you turn off the shutter sound on a K20D? I can't find the menu option anywhere.

Mowog, you have a PM.

How good it is entirely depends on the software you are using to view the captured image. I had problems with it using Lightroom, but I think the latest version of PRA sorts out the issues I had.

You're not mistaken, and I can't think of another use for it, other than studio work.

The system should be simple enough. You set-up PRA to capture it's images into a folder which is then 'watched' by your choice of image editing software for the arrival of new files. These are then immediately imported into said software and are ready for viewing/editing. Sounds simple enough, but versions prior to 3.51 did not work for me.

I think the image has been removed. I can't see it either.

Convert the FAT32 file system to NTFS. If you have any video files that you want to store on this device, and they are larger than 4Gb, they may well be truncated if you copy them to it. FAT32 has a maximum single file size of 4Gb. Not an issue for photos, music etc. but not much use for video.

Several users her use the full blown Silkypix Developer studio. There are a number of other RAW converter options that are arguably better than the supplied software.

I assume that by "remote camera disc" you actually mean Pentax Remote Assistant. This software allows you to control, operate, and capture using a PC connected via USB cable to your camera. The procedure is commonly referred to as "tethered shooting".

Sorry but I don't like it. The vignetting makes her head look disproportionately large compared to her body, she's armless.

With a GN of only 10, this flash produces less light than your onboard pop-up flash.

I wouldn't waste any time considering it.
