I'm doing some xmas shopping and want to get a flash for my brother in law who has a pentax K10D. I was going to get the Pentax AF-540FGZ (a little painfully as it's a bit over my budget) but then I saw the Sigma 530DG. Just wondering if anyone has or knows of this camera/flash combo and can let me know if it's fully compatible etc? General comments on the flash features, build quality etc are also welcome. I want to get the best flash i can but if the Sigma is 90% as good as the pentax one I think it might be a good compromise. Dec 06, 2007 at 10:15 PM

I haven't had experience with that specific combo, but I have had experience with the earlier models of the Sigm 500 on Nikon cameras. Based on my experience, I am sure the 530 model is full compatible with the current Pentax. The build quality of the Sigmas I own is close to that of my Nikon SB-600 flash. I have drop tested all of them at one point or another, but the Nikon is the only one I had to send in for repair. The Sigmas perform well. The only gripe I have with the Sigma's is that they don't tend to be forward compatible. When Nikon produces a new camera, you can't count on the Sigma's being compatible with it. The flash I purchased to use with my D70 is not compatible with my D200. That is not true for the SB-600 and SB-800 which can be counted on to be compatible with future camera upgrades. The same may be true for Pentax. I also think you'd want to get the DG Super model to make sure you get all the features in the 540. With that I think there is about a $40 to $50 price difference. If you can come up with the extra change, the 540 is probably a safer long-term bet. Dec 10, 2007 at 09:08 PM

Sigma tries hard, but there are times when you are going to have to send the unit it for upgrade, assuming they still support the unit. personally, i hated the UI on the Sigma flash units. the Pentax units are much easier to use.
