what advantage does a huge sironar 480mm have? large image circle? wide open with 11x14 film? does somebody really need it??
if i look at a fujinon 12.5/450 i can't see a reason to carry a sironar..
thanks, boris

Rodenstock didn't market it as a backpacker's lens. I expect that most of the ones sold have been used primarily on big studio monorails, where the weight is moot and the larger aperture would be a plus for viewing.
Many people who bought it used it in a studio for product photography. We had one studio that used it on a 8x10 Linhof GTL to photograph paper plates and paper cups at 1:1 for production record shots. They used the 480 to preserve the roundness of the objects as the foreshortening when doing these shots with a shorter lens distorted the shape of the product.
Not everyone used large format outdoors.
but it is not just weight also filter size and price were huge...
where are the benefits if you compare it to a apo ronar 480mm?
Much larger image circle. Handy if you're working in 8x10, essential if you're working in 11x14.
The Apo Ronar is a process lens design. It performed optimally only at f22.
The Sironar N and Apo Sironar N hit optimal aperture sooner and held it over a longer range of apertures.
The people who used long Apo Sironars in the studio, as well as Makro and Apo Macro Sironars, were after maximum detail and performance from center to edge. Jewelry photographers; food photographers, etc. are some examples. A process lens could not match the performance and optical quality for these critical workers.
It was not a matter of size or weight or price. It was a matter of performance for the task.
Bob, you mean "only at 22" or "only at 22 and above"? (I have an Apo Ronar 480)!
Thanks in advance,

22. 600mm and longer are optimized at f32.
guys working in the field may need a bright lens for architecture,, I seen a pic of a bi-plane photographed in the desert in darkness with studio flash.. The photographer used a 480mm 8.4 APO Symmar.. It was quite a stunning shot! they covered the sand with shiny black mylar and to get the depth they needed they would have needed moocho swing.. It was one of the desiding factors for my going to LF
Some guys like the angle of veiw so much they take just it on backpack journeys with their 8x10 cameras(older guys like me with bad eyes) but good legs..
