Man you are wrong here.
T20 is 38mm
T50 or 1503 is 50mm (49,3mm)
And there is always possibility that you did not place them right.
They require some fine fiddling so for example when you building a flashlight you can't just stick them to emitter and expect they will work. You got to find x and y distance where it will perfectly focus and perfectly de focus emitter.
In this case we don't have to find x y point. We got to find X only... Point where it will enlarge object without any distortion or fish effect.
And of course not all lenses will work good. You have various choices of lenses and I really think that plastic flatter aspheric lenses should work the best so I already have few 25-28mm one on order.
