Anyone tried these:

I'm interested to know whether they are a waste of money or a cunning, good-value plan....

They have several models and give no dimensions (I asked them for it) and Oly is not stated in their list, so ????
If it realy works, it could be a nice item........

That does look like a pretty good deal if they do indeed workhttps://www.chrome-scene.com/smileys/36/1242750956/smile.gif

Hi, I saw various posts one the FourThirdsPhoto forum on this a while ago, so it's worth doing a search there. Make sure you use the Google search option.

This is a similar one from a different ebay shop, but it has the measurements on the advert

The idea is based on the Rayflash so it's worth doing a search on that too.

Here's an even cheaper option.

Thanks for the info. I think the 175 bit = 175mm, so I've just ordered the F175 (seems to be the same as the RF175 in the other advert, and the way it uses a velcro loop around the flash head to adjust to any head size suggests the fitment is flexible).

The original product does seem to work:

Got an answer from the seller: he says type f155 for Oly.

I have the metz 48 AF-1 - it's down to that distance centre of flash head to centre of lens - I measured mine, it's nearer 180mm - so it's the 175 for me!

All depends on the flash: I have a Metz 44 and it measures 165mm.

I ordered one of these 5 days ago, it arrived today:D

The 175 unit fits my E-3 and FL50, the exif describes it as a fill in flash.

The illumination appears to be fairly even.

That's my impression too. If only the muppets hadn't sent me the F160! A bit of unscrewing and turning things round and all is well, but no +ve feedback for that ebay seller! The results are encouraging. There is a slight top to bottom light variation, but it isn't huge. The lighting is quite even. On 'normal' power, TTL, on my Metz 48, the result is a little dark. I applied +0.7EV flash compensation, and it is now fine. So, I think it is well within the capabilities of even the FL-36, nowhere near full power is needed. (I posted this précis on FTU as well). Looks like a useful and good-value bit of kit, just need it to stop raining so I can try it out properly.

Just a few test shots:

Standard sort of shot, using the 12-60, 45 degrees to the plane of the table the apple is sitting on. Lighting is quite even.

A bit further out, but you can see the shadows cast left and right

The worst case scenario, holding the camera as for a portrait shot, this shows the top to bottom (now left to right) lighting variation. Not too much of an issue unless you like taking shots of white tables!

A more standard type of subject (ignore the composition and the deadness of the flowers!) - lighting is quite pleasing.
