Full video and image samples below.Summary: An impressive range with little image quality loss vs the kit lens from Canon (and Nikon) but increased chromatic aberration and limited maximum aperture across the range. Those valuing convenience above image quality may want to consider this lens. A nice bonus of great image stabilization (VS) and macro like capabilities make this a fun lens for travel and family snapshots. Just be warned that in low light you will need that VS at the longer focal lengths.

Tamron 16-300 Tested on a Canon 70D

Tamron 16-300 Pros:

• Huge range- no one else offers 16mm to 300mm and does it better than many of the 18-200 lenses currently on the market.
• Decent image quality
• Good Vibration control
• Macro capabilities - it is not a macro lens but does let you get close and coupled with the VC you can get good handheld shots
• Focus sound is near silent similar to the STM lenses but. .

Tamron 16-300 Cons:

• Focus was slower than STM lenses and more likely to get confused.
• Increased chromatic aberration (purple/magenta fringe seen at the edge of high contrast areas) common in lenses like this and cheaper lens
• Slow apertures  - meaning as you zoom you will find that you need lots of light or will have a very slow shutter speed to compare. At 100mm the 16-300 maximum aperture is f/5.6. The 70-300 IS USM offers f/4.5. at 200mm the Tamron has hit f/6.3 and the 70-300 provides f/5.
• Zooming presents uneven friction (sticky spots as you rotate the lens) these seemed to decrease during testing but I worry long term about lens creep - the lens zooming as it hangs by your side.
