I am looking at the reduced lens options once you go to 8x10 , And i wonder what challenges face ULF shooters and why bother? 11x14 would be challenging but 16x20 4x bigger than 8 x10 !!what lenses would cover this image area?And yes i know Awesome contact prints no need for an enlarger yada yada ,But hey modern films films are pretty good i think they can stand a four times enlargement . And the weight OMG a 8x10 on a four mile trek is hard enough. Just curious as to why anyone would pursue ULF
