Lens hood: Metal or plastic clip-on
En cherchant sur google on trouve des anciennes annonces pour des beercan avec paresoleil en metal, d'autre en plastique....
J'ai aussi trouvé ca dans une vente ebay (ca vaut ce que ca vaut comme source, pas grand chose mais ca donne une tendance) :
The clip-on hood that comes with the lens performs well, but being plastic does over time show wear more readily than the finish on the lens. Some f/4 lenses do show up in my stock with dedicated metal hoods that were designed specifically for the lens. They seem to hold up much better as they are very resistant to scuffing, scratching and wear. Perhaps they are from earlier in the production run. Too bad Minolta didn't supply a metal hood on all its f/4's as it is definitely a superior version!
puis sur dyxum
I believe this heavier beercan is an older copy ('original' design?), for, among other things, it has a metal hood. It might be noteworthy that the lighter beercan, with the fungus, had much worse CA. Perhaps the newer copies are more prone to CA? Or was the extra CA a result of the fungus? Don't know.
Mon numero de serie de BC est 1150xxx, il pese tout nu (pas de PS, bouchons, filtre) 700g tout rond.
