Sorry Ken. I was just trying to keep it simple. Happy for you to bid if you want to, delivery would be at cost.

I clearly can't count. I should have said finishing Tuesday at 8 pm

Just in case anyone is interested I currently have listed my Optex Anamorphic adapter on Ebay. Ending in 2 days on Wednesday at 8pm. Starting price is a very modest £350 so could be a bargain. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=121340539458

I recently bought a couple of Yongnuo YN568EXIIs and I've been very impressed with how they compare to my Canon 550ex. Build quality is okay, not quite as good as the Canons but totally acceptable. In operation though they are great. They aren't exactly dirt cheap but I know Yongnuo do make some much cheaper flashes that would be worth checking out.

It's totally workable I have seen a couple of posts from people using that set up. I recall that one chap was using Auria as the recording software.

The Mix Pre-D connected to an iPad looks like a great option. 

Of course it just dawned on me, metabones are moving the lens closer to image plane, the reduction happens because the lens is closer to the image plane, so projecting to a smaller image circle. I presume the optics in the adapter are to compensate for the reduced flange focal distance so that that image is projected in focus on that image plane.

....An optical reducer is something I have long thought was possible on a DSLR and wondered why nobody had made one....   I had often puzzled over the same question. You can actually already get a Reducer for cinema lenses, Vantage have had a (expensive) 0.7x PL mount reducer available for years    http://www.vantagefilm.com/en/news/news_2002-10_01_i.shtml   But it isn't general purpose, it is only appropriate for long focal length lenses. I think this must relate to the same issue that Chris Mann identified. If the light exiting the lens is almost parallel it isn't too much of a problem if you introduce a reducer, but that won't work for wide angle lenses without losing infinity focusing.    Maybe metabones have added a collimating lens ahead of the reducer in a similar way that Canon and Fujinon do in the extender section of ENG lenses. ENG lenses used to come with 0.8x reducers built in working alongside the extender, to reduce the image circle when cropping a 4x3 sensor to 16x9. There the reduction happened in that collimated space.   I find it difficult to believe there is a conspiracy to deny us photographic reducers, Maybe it has just been too expensive to do so with sufficient quality. It will be interesting to see what the quality is of the image from the metabones adapter. I would love to see a test chart.
