How many of us do faithfully use the supplied lens hoods on their PRO series lenses? I haven't hauled the petal style hood for the 12-40 since about a week after getting the lens. I don't notice any untoward ill effects. What about those of you with the 40-150 PRO - is the hood always on or do you venture out without it? I've noticed the M43 lenses I use have very minor flare in any circumstance but am quite curious to hear what it's like with the big zoom.
