That is damned cool - that sort of digital dirt. I always get something similar on my (analogue) films but much more...
Brings some live into this clean digital world  :)
The rotating anamorphic is arty I think. I love the Moeller!

Yes, easily. But your editing experience will might be a bit choppy if you try and edit directly off your HD. You should consider faster external storage using Thunderbolt.

Took my BMPC for a spin in the Salton Sea, CA.

Vid atlantic claim the smaller sensor of the Black magic will make shooting with these adapters easier in comparison to full frame slr's where you will have to shoot with 85mm+  focal lengths to avoid vignetting.

That article mentions 2x anamorphic adapters whereas the one you listed is 1.33x. 
 
Also the century optics filter your linking too really isn't worth the money, all the test videos are riddled with distortion and it looks cheap. If you want to use anamorphic for a few short films and to play around with get a Sankor 16C, it's 2x so the image is super slim but it's the best looking anamorphic footage for this price range that isn't an iscorama. 
 
The LA700 has been used to good effect with the BMCC however I really don't see the merits of using one. The LA700 creates a bland image and the flares are less than unique. You're better off buying the vid atlantic flare filter than shelling out next to a grand for a pretty useless adapter which you will have to continue spending money on for things such as diopters to really get it to work. It's a pain in the ass you'd rather not have. Just buy a Sankor 16D (cheaper but cooler blue flares) or a Sankor 16C (sharper image), much more reasonably priced and it will allow you to have some anamorphic work on your vimeo/showreel! And the vid atlantic article suggests these 2x lenses will have a better effect due to it's sensor, check em out. We're just enthusiasts not pros so don't blow your money on the LA7200 or century optics. I was once tempted and can safely say I couldn't give a flying f*** now. I'm curious and may purchase a 16C for fun in the hopes of one day buying an iscorama 36.

cost for new PC approximately 1600.
 
If you ever plan on shooting/editting raw, you need at least a 2GB graphics card. I'd go 4GB GTX 780.
USB 3.0 or thunderbolt ports to offload the SSDs
Raid configured hard drive, or SSD  for read/write speed while editing.
Intel I7-37** or above for encoding.
 
There is no need for multiple SSD if you are doing work in the studio. Just get a caddy with USB 3.0 or Thunderbolt and you can offload you footage pretty quickly. 480 GB is plenty for shooting in the studio.

I am upgrading from my loathsome Canon 550D and will have approximately £5000 by December. The recent price drop in the Black Magic (MFT for me!) has finally convinced me after debating the merits of the Sony FS100 with myself but for the price and image compared to the BMCC it seems like common sense to me. I had my hopes set on the FS700 but for it's price tag I'll seldom be able to purchase anything else which is pointless and having rented the FS700 for my past two films I think it's time I avoid high speed for an entire production, I have a tendency to be far too indulgent with it. 
 
Anyway, I want to purchase a rig for studio styled use, matte box, follow focus etc. I want to know how many SSD's I will need (bare in mind I will predominately shoot pro res unless for a short film). I will also be buying an external battery, naturally. 
 
I also need to sell my 27" 2.8 GHz intel core i5 mac as it's incompatible with Davinci Resolve. I am begrudgingly moving from Mac to PC sheerly for the processing power bang-to-buck and will have to shell out even more money. How much would a PC capable of processing the 2.5k raw cost including all it's components such as graphics cards etc? 
 
With that money I will also be purchasing a jib as it proved invaluable in my previous short in achieving fluid camera motion which really dicks all over pans and fixed tripod shots. 
 
Forgive me if this post seems clumsy, I am still getting to grips with using a forum (as I rarely become members of ones) but was very encouraged after reading the discussions on this site regarding anamorphic adapters etc. It seems like a lot of knowledgable and helpful filmmakers actively use this service.

gives a little bit of an idea.  I think my selecting a +2 diopter was a bit overkill.  but you get the idea:)
