This is not a question but rather a comment about a question a couple of weeks ago about new Delta400.(posted 8233 days ago)The following link to a BJP article about 400asa B+W neg films may be of interest. The Neopan 400 seems to appeal to the reviewer Geoffrey Crawley who knows a thing or two about all this!
Don't be misled by the words colour film in the address; it's about 400asa B+W
