I happenned to be visiting the popular photograph (www.popphoto.com) web site and it said that the Sigma 500 series was not compatible with the K100 Series Camera. Evidently a service bulletin has been issued with a mechanasim to resolve this.

I was thinking of the 500DG Super as a long term investment so I could use it with my DL and the use it with my next DSLR (Pentax of course).

Does Promaster have a model that is DL compatible and be forward compatible?

Because the K100D uses an external flash the must be P-TTL capable (please see Leson #2 in the Flash Thread) onlytwo individual or particularmodels of the Sigma 500 flash will work properly with the Pentax K100D.

Those Sigma Flashes are: the Sigma EF-500 DG ST PA_PTTL Flash which is additionally also marked "for Pentax

And the Sigma EF-500 Super DG ST PA_PTTL Flash which is additionally also marked "for Pentax

There are also two Pentax brand P-TTL capable flashes and three Promaster brandP-TTL capable flashes also available to fit the K100D camera, they are mentioned in the posts that follow Lesson 2 in the flash thread.

I have the Sigma EF500 DG ST PA-PTTL for my DL and I saw the same bulletin. Said something about Sigma flashes NOT compatable with the K100D in SR mode or something. It went on to say that Sigma was going to issue a fix for it.

Actually they say that are offering a free upgrade for owners of the DG model.

"To overcome this, we will start supplying a free-upgrade service to our customers"

Check the Flash Thread, please. I have alternatively using both my DS and the new K100D when shooting with the Sigma EF-500 DG ST. Thus far I don't believe that I have had any problems or unexpected surprises. There are a good number of posted sample photos posted in the Flash Thread today (08/06).

It will be interesting to see what Sigma does to remedy this problem.
