I am currently considering buying a 4x5 camera. I used to shoot a Mamiya RB67 Pro. What would be the best option for an entry kit? I'm not in a hurry and would be willing to piece together a camera if needed. From looking online I am leaning towards finding a Sinar F1. What lens should I look for? I plan to use the camera mainly for landscapes. I'd like to keep the price around $400.

Thank you for any advice,
