Then I was looking for an alternative. As would offer primarily the EF 70-200 mm f: 4.0 L IS USM at. Only a real alternative it was then but not for me. Weight reduction, yes, but the volume was yet again on the border and priced but again quite high. But I squinted, though reluctantly, to a non-L lens, but then I became aware of the EF 70-300mm 4.0-5.6 IS USM. Compared the theoretical test results in short Photo Zone while the "DO" version appraised, it strapped in the store and already she was there, the alternative! Ultimately retired the EF 70-300mm 1: 4.5-5.6 DO IS USM from because of the price. Double price and for me irrelevant advantages such. As non-rotating front lens element. Last but not least it has 0.5 stop more in the minimum focal length in 70mm. Nevertheless, a class Zoom!
Then right out and took some pictures with cruddy weather hamburger, good autofocus, fast, and quiet zooming (at 300 mm but noticeably slower). Of course, there is no L and somewhere you always have to make compromises. But weight, volume, quality of imaging performance and micro USM (no ring) are very good also for the somewhat expensive dealer price. The UD lens here is tuned instrumental. The 8 diaphragm blades (good for the shape of the bokeh), the metal bayonet, the 2Mode IS and the lock were reasons for me to buy it. Negative but priced reproduced I find that although outwardly appealing outer shell, but it is made of plastic and again the lens hood must be purchased in addition to I personally find at these prices Canon unreasonable. Lens hoods are a must for ambitious photography, why they are that I explain in my review for the associated lens hood.
The iris go about from 70-89 f: 4.0, 90-135 f: 4.5, 136-225 f: 5.0, 226-300 f: 5.6. Minimum aperture at 70mm f: 32 300 f: 45th
The added advantage of my alternative is that I now covering the range up to 300 mm. Well all is not very bright. But until I really need in the area of light intensity, I have to give me 2.3 to afford even the wherewithal at 300mm.
Long story short, for a walk of several kilometers, or traveling the ideal companion. And from Preisleistungsverhaeltnis over comparable lenses of a sensation; THE RELEVANT photo forums it is becoming increasingly popular among users.
Technically:
The IS is the 3rd generation, very effective and has two modes. Mode 1 is suitable for horizontal and vertical motion compensation, the mode 2 for monopods is intended, as it only compensates for horizontal movements, which makes it even more effective, weilr an axis can be left out! Has a metal bayonet and eight diaphragm blades. Its optical imaging quality which corresponds to the L-class. Changes the length of the zoom and the filter thread rotates (very limited Polfiltereinsatz possible). Lens Hood ET-65B and possibly leather pouch LP1222 must be purchased separately.
You will find many technical terms in this release, which can not be avoided in my opinion. Most, however, can be very quickly look at Wikipedia. Should you have any further questions you can find me in the photo community.
