Thread: Macro lens for 11x14. Will the 300mm Rodenstock cover?

    Macro lens for 11x14. Will the 300mm Rodenstock cover?

    I do love table top macro of object. I have the 11x14 Wisner and want to have a really top macro lens. I have the Nikkor 210mm Macro and use it on my 8x10 but will need a linger lens for the 11x14. It is a matter of space between camera and subject. I wonder of the 300MM Rodenstock Macro will cover when I get to 1:1 and even larger say to 3x size Anyone with some solid info on using this lens ?

    I don’t know the specific coverage of that Rodenstock lens, but it should certainly cover at 1:1. The image circle at 1:1 is approximately double the size of the image circle at infinity. Most 300mm large format lenses will have coverage in excess of 600mm at 1:1 and you need 450mm to cover 11x14.

    The issue you may run into is bellows draw you need 600mm for 1:1 and 1200mm for 1:3.

    I can’t answer whether it covers, but if you really want a 3x magnification with such a large camera, I’d recommend a shorter focal length or using a diopter in front of the lens — that only serves to reduce the focal length but that translates to a smaller bellows draw and greater stability. Doesn’t need to be too strong, a +2 will help significantly and shouldn’t degrade the image quality. I actually use a 150mm heidosmat with my 11x14 and that covers at 3x with room to spare at small apertures.

    Close up enough a 300mm lens will easily cover 11x14, depends on the image ratio or magnification ratio in this example. Think how a frame of 35mm film can be projected to 11x14 print with a 50mm lens can do this, but done in reverse where the effective print become 11x14 sheet film and the 35mm film frame becomes the subject to be imaged.

    Light loss factors (inverse square law applies).

    You'll have plenty of coverage for macro work, but as mentioned, a shorter lens will overcome any bellows limitations -- and still give coverage at higher magnifications.

    Close-up lenses are an inexpensive option, but they shrink the coverage/IC -- just like a shorter lens (which is what they create).

    You can cover 11x14" with any lens if the magnification is high enough. Think about what magnification range you want and then compute what focal length lens you need.

    My "later edition" 305 G-Claron actually gives great coverage of 11x14 at infinity - and is quite wonderful close up. But for 1:1...have you actually tried that 210mm?

    If you are shooting at magnifications of 1X and higher, there are lots of much shorter lenses that are designed for close-up work, like the Fujinon A 180 & 240mm. They have ICs of 252mm and 336mm, respectively, at infinity.

    Twice the infinity coverage @ 1:1

    I use the Konica Hexanon GRII 300mm lens for this purpose on my Svedovsky 11x14 with 1100mm bellows. The lens actually covers 11x14 at infinity wide open.

    I am considering the Rodenstock Macro because it is corrected for this extreme close up. Has anyone actually used one? Is it that much better than a lens not designed for closeup work?
