Tamron SP 180mm f/2.5 63B Lens Review
It has always been one of my dreams to get this lens. There aren’t many available on the market,made only 3000 pcs for Tamron 35th anniversary. It is a very sharp lens, even at wide open and pretty fast too. It has outstanding image quality, rendering nice colours, if you ever see pictures taken with this lens you will be falling in love with this lens. I would like to say big Thank You to Mr. Paul Martinez who gave me this superior lens.
