Dennis said:I have no problem with it at all. 77mm still very useful to me as I still have my trusty D70 that can do IR like no other, after all 95% of my lens uses 77mm filters. I even shoot handheld without having to change the ISO on the D70.
Don't know why you are having problem with it leh, should be Ok one.
In fact my P&S son't give me better IR shots than my D70.
I am just trying to see if it works with the D200 but it seems like it is worst than the Canon's. I already know that this is going to be a problem even before I get the D200 but I don't get the D200 solely to do IR so no problem here. BTW setting the colour temperature directly on the D200 is not the problem, problem is it does not work. :cry:
For me i kena the hot spot problem on the D70. Must the damn lens then! :sweat:
Oh....setting the WB does not work on the D200, then it really confirms the suspicion that it is only pure monochromatic red that is passing through the R72 (eg 690-700) that is being recorded. 2500WB still won't cut it because it is so red, which is correctly recorded abyway (same for your eyes). Else near-IR will trigger a different response/colour on the sensor.
I like Oly's old P&S best. Coz it's f1.8 at the wide setting, even at ISO 64-100 you can get speeds like 1/30 depending on which cam (older is better!), no problem. Even the wind affect trees and foilage isn't much of a problem, so sometimes slower shutter speeds still got issues. Thing is that it does not go wide enough until the C-5060W, which isn't that good for IR already because of the additional IR filtering.
Here's something i did with the C-5050 at SBWR, i think handheld if i am not wrong.
