Ah, I didn't see the Istanbul part until reading your last comment. I just yesterday received the Heliopan 30.5 metal lens hood. It's nice and small, probably only about 8mm deep, threaded for a 30.5 screw in lens cap or filter at the front. I like screw in metal lens caps and the combo fits well with my 35SE.
Haven't developed any film yet, so I can't confirm that the hood doesn't vignette, but it _looks_ like it won't.
It's a metal hood, marked Heliopan Digital E 30.5. Made in Germany, so you might find a place to buy it in the EU.
