I use the 135mm El Nikkor for 4x5 negs when I want to make big enlargements, say a 16x20. Then I don't have to have the enlarger sticking out the roof. For 11x14 size enlargements, I use the El Nikkor 150. For 8x10 negatives I use the 210mm El Nikkor. All these lenses cover just fine.
Thanks guys, that's what I was thinking was more correct. I've had my eye on 3 seperate Componon-S's last mos on Ebay and lost everyone for a variety of reasons lol Anyway, I'll con't my quest on Ebay for a Schneider.
