Should I trade my lenses for one better one?

[Capt Doufos]

Over the last couple of years I have aquired various lenses and not sold any on. Do you think it would be worth while trading some in for somthing like the Canon 15-85 IS?

Most of my photography is biased towards landscapes with some portraits (Baby, pets etc) mostly shooting at the wide end.

I have a 400D
Canon 18-55mm
Canon 18-55mm IS
Canon 55-250mm IS
Canon 28-135mm IS
Canon 50mm 1.8
Canon 24mm 2.8

I would be interested to hear your opinions. I have had a lot of success with the 24mm so I would be keen to keep that or replace it with somthing as sharp. I don't have a huge amount of spare cash so most of the cost would need to be covered from selling some of the others.

Thanks

Thank you for the input, it gives me a few options to consider.

Thank you for your suggestions, quite a few things to look into. The 24mm is probably might current favourite so it's unlikely I would get rid of it.

17-55 would be a good shout, but £700 is a lot of money, although it doesn't really loose value but you obviously still need to fork out for it in the first instance.

I guess the 2 18-55's, and 28-135 won't be worth more than £200ish?
