I am stuck on M-39 thread mount because honestly lens boards for Devere 504s are the same price of a dinner for two new. I am happy with the 80 5.5 Nikkor I am using, are there any other M-39 80mm lenses out there I should look for. I know the quality between all of them are pretty much the same.
Bill, pretty much all enlarging lenses up to and including 135mm use a 39mm thread - so you should have plenty of options.

I actually like using a slightly longer than "standard" lens of enlarging - as it gives me more room to wiggle my hands as I dodge and burn.

With an enlarger the size of the 504 column height isn't going to be a problem with any length of lens unless you are into very selective enlargements of parts of a negative

I suspect almost none of us could detect the performance variations between any decent enlarging lens on even the most fabulous 11x14 print, as the performance level seems to start at outstanding and only goes up from there

As well as the Nikkor, the Rodenstock Rodagon and Schneider Componon-S are both excellent. The 80mm f/4 versions of all these lenses are 6 element in 4 groups and are considered better than the 4 element f/5,6 counterparts - but again as 11x14 could you really tell?

Happy hunting
