Today, Tamron officially announced two new lenses: a 28-300mm Full Frame lens, and an 18-200mm EF-M lens. I believe that the 18-200mm lens is the first lens with AF from a third party for the Canon mirrorless system.

Tamron 28-300mm EF Specs


  • Canon EF Lens Mount
  • Aperture Range: f/3.5-6.3 to f/22-40
  • Four Low Dispersion Glass Elements
  • Three Molded-Glass Aspherical Elements
  • One Hybrid Aspherical Element
  • One Extra Refractive Element
  • One Ultra-Extra Refractive Element
  • Vibration Compensation
  • Piezo Drive Autofocus System
  • Minimum Focus Distance: 19.3″

This seems like a pretty standard all-in-one type lens for a full frame sensor. The F/3.5-6.3 aperture will be a big downside to this lens as the light starts to fade, but for taking pictures of your kids’ daytime sporting events, this may be an option for casual photographers looking for reach on a budget.

The Tamron 28-300mm F/3.5-6.3 is now available for pre-order over on B&H for $849.

Tamron 18-200mm EF-M Specs


  • Canon EF-M Mount
  • Aperture Range: f/3.5-6.3 to f/22-40
  • 29-320mm (35mm Equivalent)
  • Low-Dispersion and Aspherical Elements
  • Extra-Refractive Elements
  • VC Image Stabilization
  • Stepping-Motor AF Drive
  • Internal Focusing
  • Macro-Like Capabilities
  • Filter Size: 62mm

This EF-M lens is a bit more interesting, as noted above, I believe that it is the first third-party – with AF – lens to mount on the EF-M system. The lens itself is not anything new. It was originally designed back in 2011 for Sony APS-C mirrorless cameras, and basically what Tamron has done here is just replaced the E-Mount for an EF-M mount. It also looks as if they have updated the styling a bit to better match the Canon EF-M lens style.

It will be interesting to see how this does, especially with Canon just announcing a new 55-200mm EF-M lens of their own. If you have been looking for a nice all in one lens for your EOS M, you can now pre-order this bad boy from B&H for $499.
