Help using oct-18 mount lenses with canon EF

[Rcorrell]

I'm looking into purchasing a set of lomo primes in oct-18 mount. I noticed that to directly mount the lens to a canon camera you have to buy either a oct-18 to oct-19 adaptor, and then an oct-19 to EF. They also make oct-18 to pl, and then pl to EF. Anyways, with either of these adaptor setups, I noticed that the oct-18 versions of the lomo anamorphic primes rear lens barrel rotates when focusing. Does anyone have any insight or experience using or converting oct-18 lomo anamorphic primes to any kind of canon EF setup???? And if so how does the focus work, or ways around it??? Any help is greatly appreciated!!

My understanding is that the OCT-18 lenses are only compatible with mirrorless cameras like the GH2. I'd be reluctant to put two adapters together because single adapters account for the accurate flange distance needed for a full range of focus, but stacking two would compromise that distance and you'd probably lose infinity focus.

With regard to the lens barrel rotation, there is an OCT-18 adapter for Micro Four Thirds cameras that has a pin built in to prevent this from happening ([url="http://www.ebay.com/itm/OCT18-OCT-18-LOMO-lens-Konvas-anamorphic-GH2-GH1-AF100-AF101-4-3-adapter-/260910613284"]http://www.ebay.com/...r-/260910613284[/url]).

You might consider looking into the OCT-19 mount Lomos instead. They are typically more expensive, but I know that they can be adapted for use with Canon cameras ([url="http://www.ebay.com/itm/OCT19-OST-19-OCT-19-KONVAS-LOMO-to-Canon-EOS-5D-7D-60D-1D-T3i-550D-T2i-adapter-/260875544582"]http://www.ebay.com/...r-/260875544582[/url]).
