50mm Enlarging lenses - which one to keep, which one to sell

[hoffy]

Howdy,

I recently bought a bulk lot (LPL-C7700 enlarger, 2 lenses, trays, lights, etc).

The lenses that came in the lot were both Nikkor F4 lenses at 50mm and 75mm. I currently also have a Rodegon 50mm F2.8. Apart from being a little dusty, the Nikkors look in good condition.

Out of the two 50's that I have, which would be better? My untrained eye can't really tell that much difference TBH.

Cheers

Test them, they should both be excellent lenses. My preference would be to keep the Rodagon because it's a stop faster.

That was my thoughts as well.....Will get right into both of them tonight.

Cheers

I'd choose the Rodagon as well. Have one in my LPL 7700 and it works a treat!
But as Ian pointed out, would be a good idea to test them both before deciding.

Keep that 6 elements Rodagon, those 4 element Nikkors (your 75mm is also the same Tessar design) were made in the 60's as budget lenses, they are great performers stop down (f/8) at the center, yet nothing special at the corners.
All this only being evident if you print larger, on a typical 8x10 size, the difference is barely noticeable.

So, hold on that Rodenstock!

I planed to improve the 50mm enlarging lenses at a community darkroom where I instruct. Using f/8 and projecting to 7x10.5 inches, I checked center against edge. I found little difference between the Schneider Componar (3 element) vs my Leitz Focotar f/4.5. A new Fuji f/3.5 was a tad behind. I'm surprised at the results but it was at f/8.

I might add that under a grain focus device you can see a crisper image with the Focotar vis Componar. Can't go wrong with a 6 element lens.
