I've got a Fujinon 250mm f/6.7 lens I paid less than $300.00 for used and the lens has an image circle of 398. It's similar to a 35mm lens on a 35mm camera. There are 240mm lenses out there with plenty of coverage too. I know Fuji did make a 210mm that covers 8x10 but it doesn't give you a whole lot of wiggle room if that's important to you.
