Special Hoods with CFV and digitals ?

[blowupster]

Hoods are made for specific lenses. However hoods were calculated for 56x56mm films. With 36x36mm digital sensors, longer hoods are needed.
As I use the kodak 16Mpix I changed my hoods and the 100mm hood works fine on my 60mm. With the CFV-39 perhaps the 80mm should me used.

I tried this hoods with my new CF-39 37x49mm and yes a "80mm" hodd for the 60mm is ok but the 100-250mm hood is too long for the 60mm.
BTW I sell the Kodak DSC and 555ELD with no reserve for the end of the week.
