Small experiment done the other day.Shot some IR with the istD, 16-45 F4 and the R72. At iso 1600 in M mode, i was shooting around 1/30 F4 and getting a decently exposed shot. Histo more or less in the centre.
Yesterday, using the D200, 35-70 F2.8, M mode and R72 filter. To get similar results at iso 1600, i had to shoot at 2 sec at F4.
Could this be due to the sensitivity differnce of the two sensors. Just curious Dave Equine Photography in York Region
