Hi everybody,
I purchased the new Tamron lens, for my Canon 5dm2. As I am no pro, or can I do any advanced test chart so I settled on the newspaper test chart and the simple centering chart.
I struggled to keep everything as parallel/straight as possible. Shot with mirror lock up, self timer.
Here is the RAW image of the newspaper test that seemed to me to be the best from the I made:

Here are some 100% crops of the image save with Digital photo professional in uncompressed Jpeg, with 5 sharpness(out of 10; Contrast :1, other parameters are default/0.

Here are some brick wall photos so you can see the distortions:

As I said, I don't know what to expect from this lens, so if anyone of you would be kind enough to give me your opinion I would be happy to hear it. If you think this lens copy is no good let me know so i return it(please explain why), or if you think the tests are not performed correctly, let me know so i redo them. Thank you.
