P-TTL ringflashes for Pentax don't exist (I have never found one). The TTL models won't work on K10D etc.
The ringflash I use is a no name version like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=160146845797 They vary in branding, logos etc and sometimes as cheap as $50. These units can do Autoflash which is a little strange on a ringflash. I never use Autoflash and set the unit to full manual. resulting in good exposures at f16, 100 ISO for a F100macro at 1:1. This works very easy even if a PTTL ringflash was available I doubt I would want one On 8/24/07, Toralf Lund <[EMAIL PROTECTED]> wrote: > The thread started by Jostein a few days ago made me realise that I just > have to buy a ring flash.
