HI All

Lenses with hotspots

Ef 18-55
Ef 10-22
Ef 17-40
Ef 28-105
Ef 35-70
Ef 28 - 200 (sigma and tamron)
EF 300 + focal lengths

this is all i have for now, but a tip what works for me is to use a piece of card above the filter  and lens which cuts out some of the hotspots, on short exposure times
