美国采购需求：鱼眼镜头、低畸变镜头、扫描镜头、汽车镜头

I'm currently interested in purchasing some lenses, specifically the ones with a certain specification. Could you please provide me with details on the available options, including pricing and minimum order quantities? Additionally, I'd like to know about the payment process and the estimated delivery time once the order is confirmed. Any information about bulk discounts or special offers would also be appreciated. Looking forward to your prompt response!
