Hello everyone. I'm wondering if I should try using lens hoods... I'm not using them now (I just got 2: P45-150 and PL25 - the last one is huge). The problem with hoods is that they take some space in the bags (if I choose to use them I would leave more lenses at home), make the lens changing process longer (if you store them reversed and the lens), and make more difficult the use of filters (ND, polarizers). And they're expensive, even the non official ones (some lens do not even have official hoods...). I'm also quite skepitcal about the hood efficiency for zooms on their longest focal length. I'm not (at all) interested in the protection they can offer, however, I'm wondering if I should use them fort the optical benefit (flare reduction, contrast etc...). What do you think? In which conditions do you use hoods? Did you experience some noticeable difference in the pictures with / without the hoods?
