It will not give the same results as the 50mm, it is a 100mm after all now isnt it? Once you get near 1:1 the 100mm has same AOV of a 200mm at infinity which is very narrow to say the least compared to a "normal" lens. Bottom line is they are very different lenses so the 100mm is not better than a 50mm, just different. If I had to go with only one macro lens it would be about a 75mm but nobody makes one! I do use 75mm/80mm macro lenses on a bellows but with a bellows the maximum focus distance is very limited and often too close. JCO

Go go the 100 if you can afford it the working distance for the same results makes all the difference in the world... Vic
