John, can you recommend any model of Graflex SLR to look into?
not sure if they will accomodate a giant aero ektar
but you could look into a super D ( newer ) or a series D...
i am sure if you throw money at adam and his pals at sk grimes
they can make any camera accomodate any lens

... if you are using small projection lenses, cinephors &c you could probably get the models
that are not 4x5 ( they made a 3x4 ) and use roll film ( 120 ) you will need a roll film adapter
if you are using 4x5 the 4x5 is the size you want, i don't think there are too many options for roll film adapters
i think there are some maybe they are rare or i am clueless about which ones are which ..
i just use black masking tape and tape a graphic23 roll film adapters to the back of my series D and never had trouble
to be honest, i've shot portraits this way, still lives, macro work, faux tri-chromes .. no critical focus issues
(the home made close up lens i made has extremely shallow DOF i've never calculated it, but the DOF is
probably at least as shallow, if not shallower than the AE )
i've never held an AE but it seems to be a giant lens i'd be leery of it on my camera's front standard..
if it was me i'd just get some junk store brass lens, or a projection lens or a tessar and stick it on whatever camera
i am using and not try to remake a solution someone else on the web has come up with. ive found
there is a lot more than a camera and boutique lens to what a lot of people are doing, and often times PS is involved
and they don't divulge that ...
it might be worth finding somene local who has a LF camera who will let you shoot some paper negatives with it
( paper negatives are cheap, film is expensive ) and it will let you see what cameras are capable of
with or without a
speed lens ..
