Saturday, the courier dropped off a 70cm beauty dish. Been looking for one of these for awhile, but didn't want to spend the usual premium. Also considering getting a portable set-up that isn't Multiblitz - probably with the Bowens 'S' fit mount, so wanted a universal fit one, the kind that uses a bolt on speedring adapter. Anyway, the only immediate disadvantage is there would appear to be two distinct areas of illumination, about 1/2 a stop between the outer edge and the center portion. This can be seen on larger group pictures but isn't an issue for head & shoulder portraits. Easy solution was to use the provided 'sock' (or shower-cap as it's sometimes called) which diffuses the light, and evens out this issue and with no loss of output. The dish also came with a thirty degree honeycomb grid, but not put that through its paces yet.
Born in 1956 (so getting on a bit now) I'm married and have two wonderful children we all live in Devon in the South West of England - on the Cornish border.
