To begin to tell you that we are on the portal Slo-Foto.net opted for a new format of the tests. Increasing the number of pages dedicated test camera equipment or just a type of equipment, such lenses, we decided to shorten the tests. So say the essence, so that the reader a quick read and see the advantages and disadvantages of a given model. The second reason is of course a lack of time apart from the portal, gallery, forum and news necessary for more extensive tests. We think it is better to publish a series of short tests in the format photographic magazines, as limited to 2, 3 extensive year. Such a format is of course an advantage for someone, and yet another failure. Less technically oriented, but only hardened or hobby-oriented photographer (most visitors to the portal), this format will be better looking, demanding, perhaps professional, especially in the first place most faithful patrons and visitors and almost certainly Sun. I hope you understand that otherwise is not, and that in this segment can not compete with the parties which used to test for "laboratory" for this equipment and dedicated employees and skilled people.

And let us get at the essence, therefore Sigmo 70-200 F2.8 II APO EX DG MACRO. This is the last of the versions of this lens. EX Code says that it is a professional series lens Sigminih with a robust architecture and the best optical quality, which the company can offer. HSM (HyperSonic Motor) ensures fast and quiet focusing, which is also home, so that no moving parts, the front lens does not rotate during AF. Speaking of focusing, I would mention in macro code, which in this case means a shorter minimum focusing distance of at 1m, instead of the standard (for this type of lens) 1.5 m. Large luminous intensity, not only provide better results in low light, faster focus (especially in these conditions) and better control of depth of field, but also using teleconverter.

It is therefore a quite versatile lens, often used in sports photography, "wildlife" photography, as well as fashion and portrait photography. And do not forget to concert photography, of course, when it comes to major concerts, where the distance between the photographer and performing higher than in several smaller clubs. Some of it will also take the trip, although for this purpose because of their relatively large weight is best. I have tested it almost all of the above categories, but for most shooting sports. In the latter has proved to be excellent. Focus is really fast and accurate. Only this is of course also depends on which type of camera lens is wound, in my case, it was the Canon 1Ds MkIII, which was focus in AI Servo mode literally sealed the facility. The difference compared with the second set of which is intended to include more advanced users (not professional) DSLR and a weaker light lens (f4-5.6) was high, despite the good lighting conditions. Is the number of photos in the "Focus", was using the Sigma and professional housing almost 100%, while in the second set of photographs neostrih around 25%. Of course, I also tested the Canon 30D at a walk in the zoo, where I was at a speed and accuracy of focus very pleased, of course, but there was no dynamic scenes as in sports photography (not the nearest to this, I was shooting at moving seals ). When it was wound on the Canon 1Ds MkIII is already solid in the fully open aperture and very good, the "wide end" for the zoom lens is really excellent in rank f3.2-3.5 which I have also used the vast majority of the time. I assume that each purchasing "bright" zoom lens, just want to, acuity in the open or nearly fully open aperture. In the f8 is sharp almost every lens, the only problem in this, because such a small aperture only rarely can use on the ground, either because of the longer focal lengths, or a desire to freeze rapidly moving object, or simply due to lack of light. Using the Canonom 30D is in the same aperture sharpness quite average. Otherwise useful when it is not a big zoom, but when looking at 100% magnification Sun her. This can be seen on the lower specimens. Vignetting is negligible even on full format cameras, visible only at 200 mm and fully open aperture. The same is true for chromatic aberration, becomes noticeable only at 200 mm. As I said at the beginning, EX designation indicates a professional series in terms of buildings. I must admit, the lens is really well made, robust and can sustain many a blow and is thus designed to demanding users, such reporters. Compared to the Canon and Nikon lenses this rank, and saw only that it is completely sealed against dust and moisture, which is particularly evidenced by the fact that there are no seals on bajonetu. Perhaps the building itself is a shade less reinforced, but certainly much more than non-EX lenses marks (or L for Canon, etc.).

In conclusion, I would mention in a very competitive price that would be easily placed the lens in the "best buy" category. In fact for that price offers fast focus and very good picture quality. It would be interesting parallel to compare the image quality and speed AF with almost twice as expensive Canon model (with Nikon, there are no comparable, whereas three times more expensive and, moreover, does not exist in the version without image stabilization-a new model). Original at evolving and really sharp acuity is at least 135-200 mm, a little better (as I said, unfortunately, I have also taken comparative photos) and the building is a little more "Panzer" and extreme conditions is appropriate. Will, of course, but should any decide whether it wants value for money or in the first place uncompromising quality and reliability of the lens, in which case the price is just the latest factor in their purchasing decisions.

As I mentioned in the description, the sharpness of the same or similar aperture (and at any focal length) is far superior to the Canon 1Ds MkIII, such as the Canon 30D. And this despite the fact that I have photos on the 1Ds MkIII covered in sRAW mode (test I combined with orders for which there was no need for a high resolution, so I save much space on memory cards and disk), but despite lower resolution detail in the photograph more. The lens is sharp, of course, exactly, I just checked with Canonom 30D prior to hire.
