Good... now I am thinking about changing my kit. I like the 50mm, I have the CF FLE... so, instead of getting the 80mm and 150mm, maybe I should go for the 100mm and 180mm. And, if I need a really long lens, I can go straight to the 350mm, instead of the 250mm.
I found that 150mm and 180mm is too close to the 80mm lens, to go to the 250mm so there is a 1:3 jump. I have two different approaches I recommend:
50mm, 80mm, 250mm
50mm, 100mm, 250mm
Personally I have 30mm Fisheye, 38mm SWC, 50mm, 80mm, 100mm, 150mm, 250mm and 500mm lenses. I use the 80mm and 100mm interchangeably. My least used lens is the 150mm, in fact a rarely use it especially since I do not take portraits very often. For vacations depending on where I am going and what I am doing so I use 50mm, 80mm and 250mm or SWC, 50mm and 80mm.
