    what lenses for 20x24" ?

    Since my 20x24" camera project is moving along nicely, I am trying t find out wich lenses will cover 20x24". Is there a list of lenses some where ? I know there are some brand new ones on the market, but what older lenses will cover ?

    19" Dagor...30" Artar...35" Artar. You could also look for a 24" Dagor( if you can find one..very rare) and the price would probably be near what a xxl 550 would cost you. Of course if you are going to plunck down that kind of cash for 20x24 sheet film then I'm sure a 4000-5000 dollar lens is no problem.

    Hi, there are some other process lenses for less money that will/should work as well. If you can find any Eastman Anastigmat process lenses 19.75" and longer will cover....the longer the better. Also Apo-Ronars longer than 600mm are fantastic if they can be had at a good price.
    Good Luck!

    I have a Manhattan Optical 19" triple convertible rapid-rectilinear that should cover nicely with the rear element or the front element solo (19-27-37 focal lengths I believe). I have only ever seen this one, so they may be somewhat rare. If you get in to antique lenses, many of the BIG petzvals listed as covering 12x16 or larger will probably fully illuminate 20x24, but of course you'll lose significant sharpness outside the listed coverage area, even if used at portrait distances.

    In modern lenses, if you can shake one loose, the 750 Apo-Germinar will cover, and the 600 Apo-Germinar MIGHT at portrait distances. The 600 will vignette at infinity. Both will likely be found in barrel.

    Scott, Good point. I use the rear half of a 14 1/2" Verito on my 8x20 and 12x20 for portraiture. It becomes a 24" lens configured this way and there is no noticable loss in performance. ( still has that gorgeous Verito bokeh). So an 18" Verito's rear half becomes a 30" soft focus lens that just may cover 20x24 at portrait distances. It would be interesting to see the results with it on a 20x24.

    I also own a Versar Portrait and View 17x20 lens f.6 ( 22 1/2") that can be used like the Verito. With using just the rear element you have a 45" lens. Now that would cover with ease. For portraiture you may need 6 ft of bellows...or more.

    Robert,

    Can you post a few pics taken with the Versar?

    Also, is the van fully converted? If so, how is it working out?

    Thanks,

    Joe

    Joe, I'm digitally challenged. But I just so happened to have just picked up a Canon 8mp point and shoot. Its still in the box. I bought it for just that reason, to get a website up and running. I'll try and post an 8x20 that I shot with the Versar here in the near future. As far as the van goes. It is far from finished. I stopped working on it over the winter. I do have a new darkbox for wet plate coming from Steve in Rochester. This will accomodate a 12x20 plate. I seem to have to many irons in the fire. Currently I'm getting the jappanned tin plate production up and running and preparing to get the first sample plates sent off to the wetheads for feedback. As for the van.. I did eliminate the black plexi door that you pointed out wasn't completely opaque. I will go with Porter's darkcloth covers for the red plexi door and window as you suggested. Plus there are numerous little light leaks coming from the rear and side doors that I have fixed. After seeing Bill working right along on his new trailer it has got me anxious for getting started to complete it.
