The best of the bunch is actually the 150 f4. All the others improve in contrast at infinity as they are stopped down but the opposite occurs at 5-6 feet where their contrast worsens as they are stopped down, except the 150 which is equally good at both infinity and closeup. Surprisingly enough the 150 is also the least expensive. I've seen it sell for as low at $25 on Ebay for the Super Tak version.
