The Pentax K-M (K2000 in the USA) is possibly the smallest Pentax DSLR body that can use your lenses.

If you go for it, and get any of the DAL lenses, be aware that lens hoods are optional accessories at extra cost on this range of optics.

I have the Auto Bellows A set and I don't think there is any difference between the K and A versions. Mine certainly doesn't have any electrical umbilical flailing around inside the bellows .

You might learn a lot about the histogram from here.

Feliz año nuevo a todos.

I think what you are calling a 'soft' face is actually motion blur. Good composition and interest but could do with some cropping of the right hand side of the forge. It doesn't add anything, so lose it.

To test the whole wireless flash setup, point your camera and flash at a mirror. Look through the viewfinder when you press the shutter release, you'll see the preflash in the viewfinder (camera's mirror still down). Examine the image to ensure you can see both flashes have lit up.

If you have the onboard flash set to controller, it's flash will be less intense than if it were set to master, but it'll be there.

You can change the cameras communication channel to match the flash.

The camera and the flash need to communicate on the same channel. Once you have set your channel on the flash (and there's no real need to change it from the default of 1 in a simple setup) attach the flash to the camera hot shoe, then turn on the camera and the flash. The camera body will then synchronize with the flash and be set to the same communication channel.

Press and hold the light/format button until the slave mode appears. Press the S button to change it. Slave mode 1 = wireless slave mode (intelligent), slave mode 2 = dumb slave mode.

Wireless does not mean radio. The wire-less communication is done with pulses of light. So that answers one question, no you can't use the Pentax AF360FGZ flash remotely without the onboard flash (or a wireless capable hot shoe flash) being used as a trigger unless you equip your camera with an inexpensive radio or IR trigger.

A slave flash is typically a normal flash which reacts to a flash of light from another flash. No communication occurs between the camera and the remote flash, unlike the wireless flash scenario where quite a lot of information is passing back and forth before the shutter is released and the flash fires.

My charger preference is the Ansmann Energy 8.
