Sorry Bazz. I don't know how to operate my CS5 well enough (hardly at all) to be able to say. Maybe someone else will jump in.
Shifting gears. I should be ashamed with myself. I've forgotten how sharp my Tamron 28-75/2.8 is... Usually need to zoom or use a telephoto to get detail, but when I view this @ 100% the distant antennas are detailed using 28mm! (f/8, ISO80, 15 sec) Taken the previous day to the ones above ... With noise only turned up to 20/100; and I could have got by with 0; I really only need that if I view the image at 100% or intend to print.
This camera body rocks!
