Hey Ben. I love the CZ21. The 82mm filter size isn't an issue at
all for me. I can also use the same CPL on my 16-35. I use
Singh-Ray 4x6 grad ND filters on a Lee holder so I just bought an
adapter ring for the CZ and the 16-35.
As for the 24L being soft, haven't seen it yet. I'll see if I can
email you a couple of shots I took in Joshua Tree (granted they are
stopped down around f/10). I love the 35 but I feel that my shots
with the 24 are more "dramatic" so I enjoy shooting with it more.
But, I'm having a hard time justifying keeping it. I have the CZ21,
the 16-35, the 24 and the 24-70 now. I kind of think I need to get
rid of something and am afraid the 24L is going to be the one to go.
I just can't part with the 24-70. I like it too much and the
convenience of a zoom for going light is too big a deal to give up.
These L lenses are great. They hold their value so well I don't
really worry too much about trying a lens out and then having to sell
it. I've been getting about 90 cents on the dollar for them. But, I
think I'm sick and need help. I love buying camera gear...
