Advice on focal length and lens for 4x5 environmental portraits
Being new to this forum and to large format photography, I would very much appreciate advice from anyone who has experience shooting 4x5 portraits.
Here are my questions:
What focal length (longer than normal or 150mm) would give me a comfortable working distance for environmental 4x5 portraits? And could you recommend a specific lens (that might sell for around $500) in that focal length?
Here is some background:
I have a Super Speed Graphic, which came equipped with the original Rodenstock 135mm f/4.5 lens (and thankfully, a working, super speedy shutter! (and just who shoots at 1/1000 anyway?!)). It’s a very nice lens, and its gentle wide angle works well for the environmental, black and white portraits I’ve been doing. But I am thinking of getting a second lens with a longer focal length in order to capture more tightly framed heads and faces at a comfortable distance and to draw background details closer to the lens.
Here are my assumptions:
1. I will be working in unfamiliar interior spaces (people’s homes) that could be spatially tight.
2. In addition to headshots and head/shoulder shots, I may want to have the ability to capture waist-up shots or fuller body shots and show some of the environment within these limited spaces.
3. I would like a lens in the 180mm to 240mm FL range. The SSG’s 315mm bellows may not allow for enough working room to focus a lens much longer than the 240mm on people in close quarters. According to some (possibly incorrect) calculations, the working distance (closest plain of focus) of a 240mm lens using 315mm of bellows extension would be:
1/f = 1/w + 1/E
1/240 = 1/w + 1/315
1/w = 1/240 - 1/315
w = 1/(1/240 - 1/315)
w = 1/(0.0041666667 - 0.0031746)
w = 1/0.0009921 = 1086 mm = 42.7 in = 3.56 ft
w = E*f / (E - f)
w = 315 * 240 / (315 - 240)
w = 75600 / 75 = 1008 mm = 39.7 in = 3.3 ft
4. I’m not really interested in a tele-design lens, since it seems like they cast smaller images circles, which would impair front standard movements—and I like those movements!
5. Even though the SSG is somewhat of a sturdy camera, my tripod isn’t the heftiest (though I could upgrade, if I had to), and consequently I would need a lighter-weight lens, something in a Copal #0 or #1 shutter or equivalent.
6. I really like the idea of an older lens that has character (like the Heliar, Skopar, Dagor, Ektar, and Raptar) and maybe isn’t optically perfect, but I also would need the lens to be set in a reliable shutter, which may imply the need for a modern lens and shutter combo.
7. I would like a lens that is on the softer side of sharp (as is appropriate for portraits), but not a soft-focus lens.
8. I would like a lens that performs well wide open in addition to being stopped down—I like the selective focus.
9. I’m shooting Ilford Delta 100, using gel sheets to increase contrast, so maximum aperture could be a significant deciding factor.
10. The lens may serve other purposes in addition to portraits, such as landscape/cityscape and tabletop photography.
Now you may say that the answer to my problem is to just get a lens and put it through its paces and see how it works for me, and I am willing to do that, if absolutely necessary. But any advance advice would be greatly appreciated!
