Re: Anyone up/in for a "Canon Spring 2013" Thread???


It is interesting that John T. reports his experimenting with 100-400.
I also tried to use a B+W CP with the lens today, and the results were abysmal: the lens IQ suffered in a major way. That\'s too bad, because any gain in polarization would be more than offset by increase in general flare, resolving power and contrast, and colour corruption. Moreover, CP adjustment on a telephoto\'s end is quite awkward, but that was kinda expected. All around a majorly lost proposition there.

This example image required a fair bit of pp before it had become half presentable.

1DX + 100-400 + B+W CP.
