Remarkable how much more image circle is available by going up 30mm more in focal length..
210mm f5.6 Symmar S image circle at f22 = 294mm..
240mm f5.6 Symmar S image circle at f22 = 337mm

BTW, a 50mm lens covers 8x10 tooo.... ponder how many 35mm film images have been projection enlarged to 8x10 prints over the decades... Will any given lens cover dependent how how it will be used, the specific lens design formula... and fully understanding the limitations and abilities of any given lens design formula, it's capabilities and it's limitations.
