Reverse lens..135mm or two lenses?
Ok so reversed you dont get more WD as you would non reversed 35 vs 100mm?
No, any reversed lens should focus where the sensor is supposed to be. The main idea of reversed stacking is high quality high (supermacro) magnification. And the setup is clumsy. With single reversed lenses, longer FL results in less magnification, and it doesn't make sense practically unless with long bellows.
If you want "ordinary" macro (up to around 1:1, that is object size about the size of your camera's sensor) at relatively long working distances and don't want to buy an expensive long macro lens, try using a normal tele lens (ca 200mm) with a weak achromat diopter, like the Marumi +3 achromat.
Or get a Tamron 90/2.8 or 60/2 DX macro if 10 cm working distance at 1:1 magnification is acceptable.
What do you want to shoot actually, what magnification (or frame size)?
