.... For portraits and people, the 110 or 180 are much better.
Tom, do you really find that you use all 5 lenses? Especially 150+180 sounds a little redundant..
Carsten,
I started with 80 of the kit, than bought the 40 and 150, 40 because its wide, 150 because it seemed like the best compromise between weight, focal length and price.
As soon as I had the 110 this became my most used lens, because it is fast, easier to focus than the slower lenses, very short minimum focus distance, and very flexible focal length. The only dowside besides price is the weight/bulk.
The 50 and 180 I got used later on.
Mostly I would carry the Hy6 with 110mm and either 40 or 50mm.
If I had to walk longer I might carry 40 and 80 because its lighter.
I really havent used the 150 much at all.
The 180 with its longer reach and speed is very nice too but its a monster lens and you dont wat to carry it long distances. However you can shoot really special portraits with it.
I might sell the 150 and maybe even the 180 - but then as long as I own ther Hy6 system I think it is great to have those lenses together-specially since they might not be manufactured in the future any more. Plus I dont think they will loose (any more) value right now- so no rush.
What I shall do is to use the 80 more often again.
