Hello, friends!

I already wrote the review and did the f/2.8L IS II USM Canon EF 70-200mm test, and today I decided to add that review of a photo in bigger resolution that it was visible and to lay out full-size JPG.
I also carried out repeated tests to exclude an error in production of lenses. It will be the second tested lens. But it will be in the second part of article, and today we watch a photo.
Today the price of a lens is ~ 1894 USD.

In the course of photographing I was interested in three moments:
1. resolution of a lens (other copy)
2. how the lens behave itself in the plan of HA on an open diaphragm
3. how the lens behaves itself on different focal lengths

I estimate the first point and I shoot brick walls and lattices which are far from me. The second point — I was shooting patches of light and branches on a contrast background. The third point — to shoot portraits and brick walls with a different scale.
As given vent “in the field” doesn’t assume scientific accuracy, all conclusions will be presented by my impressions, the benefit to me is that I can to compare everything because I test optics every day.




How behaves the lens with HA on an open diaphragm


As you can see, if you want it is possible to finish such lens to HA. But in general HA is very well controlled. You look further.


The intricate plot — branches on a light background. On the majority of lenses  there will be violet and green auras around branches. Here they are, but very thin.

As the lens proved itself very well, I subjected it to more tough tests.

F/2.8l is ii usm Canon ef 70-200mm test for longitudinal chromatic aberrations




Optimum focal for catching of patches of light.

Canon ef 70-200mm f/2.8l bokeh is ii usm
I will tell at once there is anything good. “Wadded” soft bokeh. All pictures are made on completely open diaphragm of F2.8



Excellent lens for every day. The high resolution which is a match for good lenses with the fixed focus. Very good on F2.8 and excellent on F4. Here it is the decision with a diffraction limit on the new Canon 5DS. There DLA makes somewhere F6.3 (will  be “fuzzy” above). But Canon ef 70-200mm f/2.8l is ii usm reaches the maximum opportunities on F5.6 so there is to worry about.
On some focal lengths HA are higher, but in general the lens works with them very well. The strong HA and patches of light to me managed to be caught on the 70-100th focal length and an open diaphragm. Extreme tests showed that anything ideal isn’t present. The lens still stops patches of light.

Construct of a lens is excellent, as at all “white” L-lenses Canon (unlike “black” L-ek).
It seemed to me that the image stabilizer in Canon ef 70-200mm f/2.8l is ii usm works much better, than in my Canon EF 100/2.8L IS USM.
It is possible to note that the lens worth its money and still will prove to be on the new Canon 5Ds chamber.
