    Review by 'Fowl Mouth' on item '500mm f4.5 APO EX'

    I'm truly late to the party with this oldie but goodie. After many years of lust I finally nabbed a used copy one year ago. Mine is a pre-DG. After spending seven years shooting with a Sigma 150-500 OS, this lens surprised me immediately with both how much heavier that much glass is, and how...

    Review by 'Fowl Mouth' on item '393 ( AKA Bogen 3421 )'

    Review by 'Fowl Mouth' on item 'EF 70-200 f4 L'

    Based on almost no existing poor reviews about the net, I ordered this lens to fill my need for something past 70mm in my kit. This baby "L" tele is extraordinary. The color saturation and contrast are beautiful, without much need (ever) for post processing in these regards. Sharpness is...
