Noted. That's why I posted what I posted. You mentioned many kinds of light modifiers. My suggestion included no modifiers or accessories.
Of course, you may have already made up your mind on what to use. In which case, why did you make the post? Perhaps you're looking for a spell; 'illumanitis maximus'.
P.S. If you want the best telephoto lens for high resolution and lack of distortion, then you should consider a Mamiya M645 A 200/2.8 APO. Unless of course, you already know what you want to use...
i have no preconceived decision, nor am i looking to justify a decision. i am mostly looking to travel as light as possible and make the process of photographing surfaces as easy as possible.
as to 200mm, i think it would be prohibitively long (and probably too expensive).

I honestly don't think you'll notice any distortion at all using either of the lenses I suggested, just make sure you're shooting dead square/level to the surface to avoid any pp correction. It seems you want to light a large surface evenly with only one light source without any light fall off...if this is the case and you're expecting to accomplish that goal from 30ft away I'd imagine you would have difficulty doing so, particularly when using a single on camera speedlite/ringlite. Of course this also depends on ambient light.
On another note, have you thought of an AB ring...Show more →
with shorter focal lengths, you'll notice objects start to lean toward the edges. i agree that it's probably not a big deal as an image (eg brick wall tests), but while it's subtle as a regular image, it sticks out like a sore thumb while tiling, much like keystoning to an architectural photog. i'll run some tests later to compare 50mm to 100mm, but i'm fairly sure it won't turn out well as a tileable asset.
as to the AB ringlight, i was under the impression that it requires an external battery to function, which sounds rather bulky to be honest. i already have a dual flash rig i can use, but was hoping i could use something much smaller.
