I agree with wamateur (#5), your shots are excellent, kodachromeguy. Especially the rendering of fine details in the first two images. Good one!
True, BW400CN is now discontinued, but oddly there seems to be a lot of it still around, at least in Singapore and Malaysia. when I was last in Singapore a few months ago, a shop in Bencoolen Road still had stocks of it in its window and refrigerated. I intended to buy some (not from the window supplies!) but didn't get back to the shop. I will be visiting again later this month and will drop in then.
Obviously, it's old stock. The same shop does (or it did) C41 processing, so I may test shoot a roll during one of my freewheeling strolls around the city, and see how good it is.
This may be just me, but I've used BW400CN before in 120, and found it didn't scan easily or well for me if overexposed beyond half a stop. For scanning, I've had my best results with slight underexposure, about a third stop does it best for me. As darkosaric (#3) commented, it seems a tad sharper than Ilford XP2. I dislike the heavy orange cast in the (Kodak) film, but again as darkosaric said, it prints very well in the darkroom.
All in all, BW400CN was a good film, and I will miss it when the last of my stash is used up (+/-20 rolls left). Yes, we still have Ilford XP2, which in general does what I want it to in my Rolleiflex with yellow or orange filters, so all is not (quite) lost.
