The processing is similar to the aforementioned Canon lens, quite a bit plastic, but seems not yet cheap. This is the Tamron but also very light (
What is often criticized here is the lack of image stabilization. But you knew before you buy, making no criticism in the review. In normal lighting conditions but the problem is non-existent. Clear camera shake is larger, but then you have to stop a lot more money to spend and on the Macro function (which was important to me) renounce
In direct comparison, the Tamron performs better than the Canon from anywhere (except for the image stabilizer)
With its compact dimensions, the lens fits great in my "small" camera backpack
+ Price
+ Weight
+ Size
+ Macro function
+ Lens hood supplied
- Plastic Bayonet with Metal Ring
Conclusion:
Much lens for small money, who want to have more, clear need to spend more
Otherwise, the least expensive alternative / complement the Tamron is mainly equipment
As I said, from the perspective of amateur photographers !!!
Just buy it !!!
