Tamron 28-200mm F2.8-5.6 Di III RXD A071 Lens for Sony E - Brand New review
Tamron is the first third party to make a superzoom for full-frame mirrorless, and it's an attractive choice for $730, considering the impressive image quality, solid build, and generally reliable overall performance.
Incredible image quality, for a superzoom, Fast aperture, for a superzoom, Most portable, lightweight of all full-frame superzooms, Attractive value for the performance and quality, Weather sealing and solid build quality, Impressive autofocus speed & reliability in most conditions
Besides sharpness, other image quality aspects are less-than-perfect, Build quality not "GM" status, No-frills basic physical design, No VC (OSS) which is increasingly useful at longer focal lengths, Odd thermal noise pattern at 28mm, ISO 12800, 30 sec.
