Here's my DIY focus assist lamp. Total cost under US$0.50 for a DX keychain flashlight and a strip of gaffer tape Doesn't affect use of pop-up flash or hotshoe flash.

Well my flash assist on my Vivitar DF-383 doesn't reach that far and isn't as effective as a bright beam of light like onset other DSLR's. Even the Entry-Level Nikon D3000 has it. I need a workaround somehow because it's needed in low light (sometimes I don't use flash so the red assist lamp wouldn't apply in this case)
The reason people mentioned the Pentax flashes is they have a spot beam mode. In this mode the flash is not added to the exposure calculations, or is it activated with the shutter. The flash simply provides a spot beam assist when needed. The Metz 48 AF-1 and 58 AF-1 also have this mode. There may be others.

Thank you
Russell

It's dark, no one can see your camera anyway Anyway DX sells the keychain flashlights in black too, if that helps

Nope, the plastic used to make the flashlight is black and not white

Also with red light?
- That would be a good combi with e.g. Sigma 30 or 50 mm F1.4 prime

I feel there must be a product out there which is based on the following steps.

Obtain wiring diagram of Pentax brand flash with spot beam light assist.
Reverse engineer spot beam light assist and camera communication.
Reproduce the spot beam light assist and package as a hotshoe mountable module.

Maybe add another shoe on top of module for flash, etc or make a slim line hotshoe module with the spotbeam light assist to the side.

.......we need more electrical engineers in this thread.

I'm not though

It seems to me a good idea anyway

Or, you could buy one of the older 35mm cameras like the PZ-1P that has the focus assist light built into the on-board flash.

Or you want until Pentax build it back in...
- I think it is also a pitty they didn't add a connection for an external stereo microphone, but on the other side I like the compactness and IQ/price balance.

Pop up the flash before you autofocus, and then it uses it as the AF assist light, then after the AF confirm just put the flash down before you fire.

Easy and free
Just wanted to note that if you put it in wireless flash mode, you don't have to put the flash down, the flash won't be in the exposure.

The K-x does pretty well with the pop-up flash compared to other bodies that need to strobe the pop-up in low light.

This disables SR however.
