Old Flash on new cameras
« on: November 13, 2012, 09:43:08 PM »
Hi,

I'm new here, so don't know whether I'm in the right place but here goes. By way of introduction I live in Wales, UK and have been into photography for some twenty plus years - I have a few old Minoltas and now use a Sony Alpha 100 since it came out, and last week acquired an A77 to add to my collection which includes a Dynax 500si , Dynax 7 and 9. Anyhow my question relates to old flashes of which I have a number. The Vivitar 550fd works well on all the minolta cameras and the A100, since I bought the A77 I tested it on that and again it works well. However, this is a tilt only flash and no swivel. I also have a Jessops 280 ABZ that is both tilt and swivel, so before rushing out and spending some £300 on a new flash I wondered whether this one would work. Having checked the A77 manual it says that you can use any flash with a sync lead upto 400 v with opposite polarity.  The Jessops flash is rated at variously (depending where you look) at between 70 -260v, I have tested it on a meter and it repeatedly peaks at flash burst at 70 volts. So in theory it should work, but obviously, it can be a very expensive mistake to make, if it goes wrong. Does anyone have any advice  thoughts or experience in using these types of flashes on modern cameras.

Many thanks,

Welcome andens.

Sorry I am unable to assist you. I am sure someone will have experience with this.

Good luck,

Clive

Welcome from me as well.  I also am not familiar with that flash so cannot help directly but if the Jessops 280 ABZ does not fry the A100 then I believe it will not fry the A77 either....john

Just a quick update, I tried the flash nervously after using the studio flashes both wirelessly and with sync cables. Actually, the battery on the trigger was running low, so I tenderly plugged the sync cable from the flash into the camera and pressed the remote. The result was the flash worked fine and the camera ran smoothly and is still alive. Having said that I would not have tried it, unless I had measured the flash output and checked the voltage capacity of the camera first. I'm not sure of the trigger speed on this flash but no doubt I'll work that out. Are there any other issues that I should be aware of when using a film flash on a digital camera?

Hi Andens,

Welcome to the forum. I have used 'older' flash's on my A200 in the past but like you have read up and tested them before doing so.

There was a thread about this on Dyxum where a A700 user used a Vivitar 285HV with an ISO adapter on the A700 and the camera was fried.

I tend to only use Sony flash's on camera now and just use my legacy flash's as remote fired slaves.

Rgds,
Dave

Vaughaag,

Hi, and thanks for the welcome. Whilst it it useable, I won't be using it that much again, as perhaps it is just me but I noticed the top LCD display blanks out and then comes back. So from now on, I won't be using it any other way but as a remote (wireless) slave. Unfortunately, that means its now time to buy a Sony Flash (and more triggers) and spend not doubt a fair few pound in doing so.

Many thanks,

Andens
