A little quiz. Pick the photo that came from which lens. Both shows were taken at the f/4.0 1/50. One lens it a Pentax A 100mm /4 Macro and the other a Vivitar 105mm /2.5 Macro. No PP, straight JPEGs from a K10D. Tripod and remote used. Click to enlarge. My basil plant died, so sage will have to do.
I'll go with #1 is Vivitar 105mm but you forgot to set the white balance to tungsten . Without 100% crops, identical focus and proper white balance it's hard to tell. Even then, I might be at a loss!
Judging from the background size, my guess would be the Viv 105 was used to take #1. Otherwise, I will agree with cmv. Without 100% crops - it is almost impossible to tell which is which.
