Today we rec'd the new Metz 54MZ3 in Pentax, and Nikon fittings. I have not had time to examine in detail, however suffice it to say that I am impressed with the build quality, but must spend several hours with the instruction book. It's significantly different to the 40MZ series, in basic design, and info input. The MZ-S is not mentioned as one might expect, however the flash does claim full sync among the many features. I will let you all know as I have more time. Kind regards Peter - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
