    I'm in the process of putting together an 8 x 10 enlarger and am wondering about the lens(es) to look for. I've heard that the old process camera lenses should work well as enlarger lenses. I have a 355 G Claron - would that work OK? Do you think an APO Nikkor 240 mm lens or work or should I go with something larger than that. What should the "standard" size lens be for 8 x 10 negs?

    The 355 Claron would be a nightmare, it's bad enough with a 300mm Comonon S, the 240mm Componon's, Rodagon's etc are designed & recommended to cover 10x8, the 240mm Nikkor should be similar.

    With the 300mm the column height & bellows draw needed to print 1:1 is approx 1.2 metres as soon as you start to enlarge you need to drop the baseboard & have the head at the top of the column, this limits you and makes working difficult, with a 240mm it's easy far less height's needed (1:1 is only around 48cm neg to paper.)

    300mm and 360mm. There are also 'wide angle' lenses available around 260mm.

    You might look at the Rodenstok & Schneider figures.

    I have a 210mm Componon and that only just fails to cover 10x8, while my 240mm Rodagon covers with room to spare as it's designed to be used as a 10x8 lens, as is the 240mm Componon S. You could also use a 240mm G Claron.

    What will you be using as an enlarger, Dan?

    I'm converting an 8 x 10 camera in to a horizontal enlarger. Still am working on a light source. I looked at converting my 5 x 7 enlarger to an 8 x 10, but I think there would be clearance problems and would not be able to raise the head high enough above the base board.

    It also depends on the print size... since an 8x10 print needs so much bellows draw, you can get away with a short lens without getting ugly corners.
    I use a Schneider 240 myself. It gives a nice working distance.

    I use a EL-Nikkor 240mm. It works great.

    I'd go with 300mm since you won't have a height issue.

    A 240mm is far better :D But a 360mm would be a door stop. :smile:

    Peter, what is the thread size for the 240mm EL-Nikkor? I'm looking at getting one, but it may not have a retaining ring.

    I will have to measure. I had a board made for mine with the threads cut in.

    I have a perfect 300mm Rodenstock Rodagon I may consider parting with.
