    Need some help with these lenses

    I recently acquired the following lenses for my large wet plate adventure,

    Nikkor apo 480 mm 1:9 (beautfull lens, light and even fits in a large universal iris !)
    rodenstock klimsch apo ronar s 800mm 1:9 (heaaaaavy)

    although they are slow ( at least for wet plate) i want to try them outside for landscape. I treid to find some info about these lenses in the net, but so many answers...

    what is the coverage of these lenses ????

    According to Nikon, the 480/9 Apo-Nikkor covers 46, probably at f/22.

    Rodenstock claims 42 at f/32 for the 800/9 Apo-Ronar.

    You'll find claims that these lenses cover enormous circles. This is true, but at 1:1, not at infinity. Many of the published circles are for 1:1.

    Thanks !

    But how about wide open ?
    I think i will have to use them open as collodion is slow.

    Alex, they don't gain a huge amount coverage-wise by stopping down. Don't have either of those focal lengths so I can't give you an exact answer though. Don't imagine they get used much wide open at infinity so you won't get many replies.

    What plate size are you aiming for?

    My new camera is 20 x 20 "wet plate.
    I love to uselenses wide open as i prefer to have shallow dof.

    The 480 APO Nikkor covers my 12x20 Korona nicely with plenty of room for movements.
    I haven’t tried it wide open but around F22/32 it covers with enough room for a good 2-4” of rise.

    Alex, I gave you the angles covered. Do the arithmetic to convert to circles.

    Not "stupid" at all ... I've been doing this for 5 years, have 20+ lenses and don't have a clue how to figure out image circle from the angle of coverage information ... and we're probably in the majority here.
