I was looking in the loft for the pentax and praktica cameras I know I have somewhere but found my old slr camera kit. First proper camera I ever bought....There's also another roll of out of date Jessops to experiment with!

The old jessops flash I had with it is also in the bag. Will that work with older minolta cameras like the minolta 7000 safely? I know some put large voltages across the hot shoe so I don't want to risk frying the camera if it is a no-no.

Just need to find a pair of LR44s and I can see if it still works. The shutter magnets have a nasty habit of sticking so it will be interesting to see whether it does.

Lenses I have with it seem to be a centon 28-70, 70-210, 500mm mirror (now I have 2) and a 50mm 1.8. Also got a set of extension tubes and a cable release.
 
Always good to hear of old cameras being resurrected, post some pics when you have taken some shots with.
 
Your flash and camera should be fine, it's usually only new fangled cameras that are in danger of being fried by using old flashes on them. Old cameras + old flash should be fine.

There is a lot of paranoia and mythology involved with flashes. Most modern cameras are rated at 250v for flash trigger voltage.

It's good to know I can use that flash with both. Assuming it still works as the jessops flashes were never very robust.
 
Only two Jessops models mentioned here:-

But the Minolta 7000 is not an old mechanical camera, and can only say what I would do and that is:-

To be safe use a flash gun with trigger voltage less than 9v, but it might be worth checking what is the safe trigger voltage for the 7000 :shrug: or another way would be to find the flashgun made for the camera, note the trigger voltage and once you know that, then any flashgun would do that is similar.

According to the web the trigger voltage of the older Jessops flash guns is in excess of 230v. That would be likely to fry the electronics of your Minolta. You can check the trigger voltage if you have a multi meter. To be safe with a modern camera you should be looking for a trigger voltage of around 6v.

The matching flashguns for my Minolta X-700 and Canon T70, T90 are from 3.75 to 5.24v....the 2800AF flashgun that might be suitable for the Minolta 7000 ??? is 1.7v, wow that's low h'mm ?
 
The older flash is minolta md dedicated one. The later one I have is a minolta AF so I wonder whether the later one would be better with the 7000? I know I can't use the former with the minolta AF cameras as I specifically asked about it when I got the 404si. That had a pop up flash anyway so I didn't bother getting another gun.
 
Quoted trigger voltages for Minolta AF are - 1800AF 1.88v - 2800AF 1.74v - 4000AF 1.8 - 2.5v

Well if the voltage is the same then the probable difference would be, when looking at the hotshoe all the pins around the centre pin (my T90 flashgun has four below the centre pin :eek: )........for matching a camera (and it's use) to a flashgun.
 
I tell a lie. I took the bag off. The flash I had with the centon was a centon FG30 flash not a jessops!

Well I wouldn't use that at 200v :eek: on any modern film camera, would be OK for your old Praktica.....when dismantling old flashguns they always say "be careful of a shock" and although the current is low I did notice on my very old Pentax that the camera's flash contacts need cleaning once in a while, so there might have been a very minute spark each time I used a flashgun.

I'd use the FG30 with the centon.

Jessops page says the minolta AF version of the 360AFD has a trigger voltage of 6v so that should be ok with everything minolta AF but still a maybe with the 7000.

Well maybe for the 7000 :shrug:...it's your call unless someone on google has tried it. Anyway are all the pins on the hot shoe the same, as when I use some of my flashguns on different cameras, they don't always work properly e.g. I don't get the flash symbol in the viewfinder and I don't want to waste film to find out as I'd rather buy the correct flash gun for the camera.
