Dine is apparently made by Sunpak or has/had some kind of affiliation with them (to the best of my knowledge). This flash unit looks OLD, but by old I mean that in a classic way. This looks to be a workhorse unit. It seems to pack plenty of power (shooting 1:2 or 1:1 will require F16 or smaller), extremely fast recharge time, and works great on my E-510. I recently picked it up on ebay for around $45 shipped. I tested the trigger voltage, and it's exactly 3.50 volts and perfectly safe for DSLRs. It has two auto modes and a manual mode that allows for adjustable power. It also features a switchable flash head mounted atop the ring. There is even a jack for an external high-voltage power supply (I don't have one). This is quite the Cadillac (http://en.wikipedia.org/wiki/Cadilac) of ring flashes.

Ring diameter is 62mm. A 52mm - 62mm step-up ring allowed this to mount nicely to my 35mm macro.

In short, it is excellent and I highly recommend it for macro and short-distance work. :D Probably works well for things such as dental shots.

See pictures below. (please excuse the Sony DSC-P73 p+s)

Picked one up off of ebay for $30.

Had to jury-rig a cover for the ring flash portion as the original part was missing.

At least for me, it has been challenging to find the right settings to use but I know very little about how flashes work. Still, I've gotten some useful results.

I'm using the Sunpak STD-1D module although it originally came with a different one. I've mainly used it on my 410.

Great deal! I've found the most difficult part is how the distance between the ring flash and the subject has a HUGE affect on the exposure. On my 35mm macro it lists the magnification values on the barrel. I try to keep those numbers consistent to keep exposure consistent as well. It's not the easiest flash to use, but it does have power, and I think if I practice enough with mine that I can get proper manual exposure with it.

Are you able to use this with the 35mm at closest focus?

If your subject is three dimensional, raised up, and is smaller than 52mm... Yes. (for example, the tip of your finger)

If your subject is two dimensional, and on a parallel plane with the camera... Yes. (for example, a document)

If your subject is three dimensional, and larger than 52mm... No, the ring flash will likely intercept it before you reach 1:1, however, you can get quite close, maybe 1:1.3-ish. (for example, a close up section of a object larger than 52mm) The EC-14 should allow greater than 1:1, but perhaps not the full 1.4:1 available without the ring flash.

Thank you.

Unfortunately the same issue I had with the Oly SRF-11. Even holding it back at the tip of the lens didn't direct the light to the subject well at 1-1.

From the looks of it, even the original Oly ringflash used with the OM 20mm f 2 would work either

Doh, forgot to add that the lens is a Sigma 105mm. Sometimes it seems like the focus motor isn't strong enough to retract the barrel if you're pointing it down towards the ground, but the unit isn't that heavy.

That's a good thing to notice. Thanks for mentioning.
