Sigma EF-530 DG ST with K30

Hi all does anyone know of any issues with a Sigma EF-530 DG ST working with a K30?

Thanks

Hi Steve I have the EF 610 the sigmas do the job and work well off camera, probably not as good a the pentax flash guns but not so expensive

Regards Dave

I think the EF-530 DG ST doesn't work in wireless work and has only two power setting in manual mode.

For a full featured flash in the Sigma line, you need the EF-530 DG Super or EF-610 DG Super.
