The original 55mm ring at the far right.Amazon-owned robotaxi firm Zoox this week announced that it has acquired Strio.AI. Here the Minolta adapter ring is at the back. On the right, a 72-55mm step-down ring, a 55-55mm spacer and the original 55mm ring from the R1200/1200AF ring flash. Here on the left, the original Minolta 72mm adapter for the R-1200/AF1200. I have not used it recently but i think it can also work with the Original twin flash adapter. Total cost from Chinese makers could be as low as 5$ on this one. Tried it with the ring flash and even with my E-Mount 90mm 2.8 Sony Macro (62-55mm in this case) and i did not get any vignetting like i was expecting. If i were you i would start by trying a simple 72-55mm step-down ring coupled to a 55-55mm step-way ring directly on your 55mm OEM adapter ring. Lens shades optional in case stray light might become an issue since with the normal adapters, you can not use the original shade anymore !Īfter finding the 72mm adapter for the twin flash, i noticed how small the hole that allows the light to get at the lens and this made me think that a 200mm lens having such a narrow angle could still use a narrow window in the adapter. The twin flash holder actually gets pinched at the 77-77mm step-away (spacer) ring. Here was my 25$ ( approximate) use of step-up/step-down/step-away (77-77mm) to get the Twin flash holder pinched within these.

And it's listed as a ring light instead of a ring flash. B&H actually lists another unit that looks identical but is sold as a "BOLT" unit. I'm not sure who actually makes this unit, I doubt it's Polaroid. I have no idea if spare parts - as in mounting rings - areĪvailable. It uses the old iISO flash shoe - you'll need an adapter for newer bodies.ģ. But power level is easily adjustable and I'm using it for fill flash, so no biggie.ġ. Not as powerful as my old Minolta gear, and there's no info on how powerful it is. I assume the last 2 are to provide something of a color cast correction if shooing in tungsten/fluorescent ambient light.Ħ. It comes with 4 snap on "filters" that fit over the ring - clear, diffuser, a blue one and a yellow/amber one.

You can opt for the full ring, or either half. It can be used as either a ring light or true flash unit.ĥ.
#Bounce break strio manual
It's simple to operate - which is good because the "instruction" manual isn't much.Ĥ. It fits lenses from 49-77mm with the included mounting rings.ģ.

Cost - $50 is about as inexpensive as it gets, in particular since I was anticipating spending several hundred dollars.Ģ. Here's the link, I'm not going to repeat everything, just go over the good/bad stuff.ġ. I started looking for a 3rd party ring flash, and stumbled across this Polaroid unit at B&H. The old Minolta rig only comes with a 49mm and 55 mm mounting ring the Tamron has a 72mm thread, which obviously isn't going to work. I'm happy with the new lens, but wanted, in particular, a ring flash to use with it. Recently I purchased a Tamron 180/3.5 macro to replace the Minolta. I've long used a Minolta 100/2.8 D macro lens, and have the MFC 1000 flash controller with both ring and twin flash.
