Prime:
Canon 50mm f1.8 (easy one $135 ) SHARP!
Cosina 100mm f/3.5 macro ($280)
Standard Zoom:
Tele Zoom:Canon's old 70-210mm f4 ($???) Good: Pictures are sharp and constant f4,
Bad: push/pull design and AF rather slow!
Canon EF 28-105 USM 3.5-4.5 (New or 2nd hand @ $280)
Sigma 28-105 UC 4-5.6 (used @100 - good build and AF, optics as good as canon 28-105)
Tamron 28-80mm f3.5-5.6 ($140+) better than canon kit lens.
Sigma 28-80mm f3.5-5.6 MACRO Asp HF (about$180) OK, better than kit lens.
EF 28-90mm f4-5.6 USM - cheap plastic kit lens ($50-$90, old)
Wide Zoom:
Cosina 19-35mm f3.5-5.6 (about $250) Sharp for its range, nice color.
Tokina 19-35mm f3.5-5.6 (about $199)
Tamron 19-35mm f3.504.5 (think its otherwise known as the Plastic Fantastic) - $250 (old from P&G, cheaper if u get it on B&S)
Sigma 18-50mm f3.5-5.6 DC ($180-200 new) For the price paid, it's a pretty sharp and versatile lens. Good CA control and barrel distortion is quite minimum. Noisy AF and some flare issues cause the hood supplied it a bit short
Tele Zoom:
Sigma 70-300 f4-5.6 APO Macro Super II ($330) Better than Canon 75-300 f4.5-5.6 USM III
EF 75-300mm USM III (even tho its quite soft on the extremes, most newbies i know started off with this lens) - $120 (old)
