Anyone know what the specifications are on the trigger voltages the a-100 can handle via the Hot shoe?

I am interested in using non Sony/KM flashes (older units) with standard ISO hot shoe. I understand that the FS-1100 will work.

But need to know the trigger specifications that will work without damage to the camera. Voltage range

I am also aware of the Wein safe shoe adaptor available. But several of my older flashes may fall within the safe quide lines of the trigger voltage without a safe shoe adaptor?

Manual mode is my only requirement with older flashes.

Thanks for any feedback Bob

Reference URL would be helpful if the specifications are on-line.

Hi steel120,

I spoke to a Sony tech support guy who said max voltage should not exceed 24volts. I use a guideline personally of not more than 12volts. There are hundreds of flashes at botzilla.com. They give make/model/and voltage. Many are far less than that.

Good luck.

Thanks GeorgiaBoy: From Panama City Beach...Bob   24v is good news.

I have several older flashes, that I measured the voltage at the flash and most are less than 15-16 volts D.C. I used my old Ocilloscope to look at what was going on. I also reviewed the site that has many of the flash unit trigger voltages posted, but my concern most were from standard digital voltmeters, which will not from my understanding give you the peak voltage.

I have the following Minolta 2800AF(? volts), Albinar 924(15-16volts), (Two) Metzs 202 with a guide number approaching 200, however the metzs are 200+volts trigger. Need to measure the minolta 2800af.

I was dumb in using the forum, I did not notice that there were 9 pages of responses to the flash forum until a few minutes ago. I did see you like the 433D a great deal( I was about to sign out when I saw your reply and see what was on e-bay for the 433d). I was extremely dissapointed in the guide number of the a-100 on board flash gn of only 12.

I have ordered the FS-1100 clone and awaiting the china connection.

I am from the old days, gn/feet=f stop...easy enough

I really like the A-100 since I had a closet full of Minolta lens...orginal owner. Using Lightroom to edit raw format.

Thanks Bob
