No, if you adjust the sensor distance with spacers I mentioned earlier, autofocus will behave as before.


Calculator is here.


on Astrosurf webpage they say 350d needs to be adjusted by 0.8mm

External and internal UV_IR CUT filters will behave the same... You will still need to play with white balance for daylight photography.
Rocolax (that I tried to use) will be OK for daily photography (but it is not good for Halpha, it blocks it).
