I recently purchased a 500 c/m. I have since added a 50mm and 150mm and am looking for my middle lens/es. I have poured through endless forums but thought this would be a great place to get some more definitive opinions. I am trying to choose between the 80mm, 100mm, and 120mm makro. From the images I have seen, I love the sharpness of the 100mm, the OOF of the 80mm and the combination of the two from the 120mm but fear I will loose too much sharpness at infinity. If I got the 120, would probably add the 80 later. I shoot primarily landscape/cityscapes and some portrait. From your experience with these lenses, which is your favorite and why. Thank you all in advance. These will more than likely be C lenses as that is my budget for the time being.
