Question: Is this lens Compatible with canon 70d and video
Document: The combination of the reduced size of the popular APS-C sensors with advances in optical glasses and fabrication of aspheric lenses has allowed the creation of compact lenses with remarkable zoom ranges. This lens spans 16-300 mm, a zoom ratio of 18.75. (With the Canon APS-C factor of 1.6, this is a 35 mm equivalent of about 26-480. At the long end that's quite a telephoto!)
I recently purchased this Tamron F/3.5-6.3 16-300mm lens as an all in one utility lens for my Canon T3i and I was not disappointed. As stated in the description, this lens zooms from 16mm to 300mm. I have used this lens as a macro lens for flowers as well as a zoom lens for moon shots. All of my pictures are sharp and clear. The auto focus is extemely quiet, fast and accurate when there is adequate light.
Bought this lens because I needed a little more zoom. I have a Canon 55-250mm but needed a little more. However I took pictures using my tripod to make sure that I was in the same position and this lens did not zoom any closer than my 55-250mm. There was also more grain in the photo as well. Another thing to zoom you had to turn the lens the opposite direction. Never seen that before. Personally believe something was wrong with the lens I bought.
I have a Canon 70DI try to take some pictures ridding in the monorail at Disneyland.25% of all my monorail pictures are out of focus.Very slow on the focus.Half the time I can't tell if the VC is working or not.I turn on the VC... Take a picture...
The quality of the lens is not what  I expected when I turn the zoom it's not as smooth.
I use it to replace carrying a macro lens, mid-range zoom lens and a long zoom lens. You will not be disappinted.
It's sharp, but not razor sharp. I see only a little pincusion at the long end, but some clear barrel at the wide end. All typical of this kind of lens, but overall fairly well controlled.This is a lens for carrying around, taking on a hike or a trip, or to an event.
I did not like this lens at all. When shooting at 300 mm after pushing the shutter release button the picture seemed like it move. For the price it seemed to be a little on the cheaper side. I return this lens the very next day. The place that I bought it took it back no questions asked.
Mounted on my 70D it has a nice balance. On a smaller body it might seem a bit big for a "compact" zoom.Overall it feels well made, a bit better than the 18-270.To be clear, my rating is for its class, not against a set of prime lenses or a pair of smaller range zooms. This is a lens for when you want to travel light.
Only once did my camera lose connection with the lens. Simply removing and reattaching the lens served as a rapid fix. And it is actually more more compact than my Tamron 75-300mm zoom lens with a much quieter autofocus mechanism.There zoom is slightly stiff but remains easy to use. There is no drift of the zoom when the lens is held facing down. And there is a lens zoom lock at 16mm when the lens is not in use.
Answer: Yes, it is.
