    Make sure to look for one in good condition, with no haze in the lens or scratches, etc.
    what he said....

    alternately, i've used mine with both a cold light head and the proper condensers/lamp for 2 1/4... once you start to get "complicated" you move beyond what is a rock solid, reliable enlarger that is a joy to use....

    should you need parts, harry taylor in CT harry_g_taylor@sbcglobal.net is an expert on omega enlargers and very helpful

    enjoy

    A 150 would require a longer cone.

    Thanks

    if you can't find the plate on ebay, you can get it at freestyle - an advertiser here, or harry, as noted previously.

    For the record, a 150mm lens with the proper cone on an Omega D-II will enlarge a 4x5" neg to 16x20" with the standard column. I don't know if there was an extended column that worked with a D-II, but you could raise it or easily rotate the column to project on the floor, if you only print that big occasionally.

    Used enlarging lenses are pretty cheap, so there's no reason not to use modern 6-element lenses from the major manufacturers, and it's not much of a stretch to go for Apo lenses that were formerly very expensive (with the exception of Apo EL-Nikkors, which are still very expensive). Ctein published an article many years ago, showing that there was more sample variation among lenses of a single manufacturer and model than differences between comparable lenses from different manufacturers.

    ALL CAPS BECAUSE THIS IMPORTANT. A 150 used a 6" lens cone. A 135 a 3 1/2 . IF YOU PUT A 135 ON THE 6", YOU WILL NOT BE ABLE TO MAKE LARGE PRINTS.

    BECAUSE IT IS TOO FAR FROM THE NEGATIVE.

    IF YOU PUT A 150 ON A SMALL CONE , THEN YOU CAN NOT MAKE SMALL PRINTS.

    SO MATCH THE CONE YOU HAVE.

    A 150 cover 4x5 "better". 135 was for 3.25 x 3.75 " negs.

    When you look at the rodenstock information of the 135 rodagon you'll see that its listed for 4x5 and not for smaller formats. I remember finding some MTF curves for both lenses somewhere on the net and the differences between the two lenses were marginal IIRC. The advantage of making bigger prints with less column hight is a very big plus for the 135 mm for me. And in my personal experience it is an excelent performer.

    I have used a 135 El Nikor (3 1/2 inch cone, as Ronald says) for 30 years for 4x5 with a D2, and have never seen edge or corner problems (and I have looked for them). I, too, enjoy the increased projection scale.
    FWIW - I always (always) use the lens 2 stops down.
