My intent is to shoot 8x10, color negative film for big if not extreme enlargements (like 150 x 100 inches). I shoot contemporary art what means that I am not concerned about weight of lenses because all the scenery and subjects are in urban zones and my camera is an aluminum Gibellini.

I like tech specs but to a certain degree. I feel that if I buy an very-very good lenses I won't change them for a long time. If it make a difference I would just buy best choices.

Would you guys be so kind to recommend me three basic lenses? Something about 240-250, 300-320 and 450-480 focal lens.

thanks.

ps I have had some personal discussions with few users of this forum but than I've been suggested to open a discussion about it.
