Post Vivitar ring flash

Has anybody used one of the above for Macro work? (its the 5000 model)

It takes 2xAA batteries, so I assume that it is OK to connect to my K7

Regards

If you can confirm it is on this list with a "good" voltage (which it looks as if it might be), then fine, otherwise run a test as shown here. Some early Vivitar's have very, very high voltages (I have a 283 with 280+volts!) and it does not follow chronologically even within same model, eg. some older 285's are lower voltage than newer pre-285HV models. So probably safer to test if you can borrow a meter.

Note that using it once with no ill effects doesn't prove anything. It is cumulative destruction of the shutter contacts that is potentially possible.

OTOH be aware that very few people appear to have actually damaged their camera, and those who have have been professionals using flashes every day and with high shutter counts.

Thanks for the information, its the Vivitar Macroflash 5000 model. and connects to the camera via a standard sync lead, so it's not using the hotshoe for this flash to work.

On the list it says its EOS safe, with a voltage of ~6v

Glad to have helped.

Whether it's using the hotshoe or sync cord is immaterial. All feeds to the same place.

As you say, it is probably fine. But I'd still check when/if you get the opportunity. Simple meters are so cheap now, you're bound to bump into someone who has one. A v. cheap one will not be particularly accurate, but then you're only looking to see it it is in the 6v range or the 60v range - not too demanding a test.

Just as a follow up, stumbled across this site when looking at ring flashes.

Link - ringflash.co.uk/category/guides/

This could be of use to others

I have just checked the trigger voltage and its 7.9v DC so I assume that is OK (Starblitz 1000 Auto Macro-Lite)

Well within. Pentax seem very coy about max voltage, but most references have this at 25v at least, a few at 12v. I think it was only Canon that was as low as 6v, so you should be good to go.

The effect on the shutter contacts is thought to be cumulative over 1,000's of shots, so for an occasional use item like a ringflash you could probably risk 50v with no downside. It's the old Vivitar 283's and things like it that need to be treated with circumspection - and I don''t just mean with respect to the camera - at 270 to 290v!
