The sharpness and color reproduction is absolutely beyond everything else hangs out in this price league. The ability over the entire scale with an aperture F2.8 makes photographing the (perhaps) some missing millimeter focal length at the top more than compensates. Personally, I have the "Always-on" rather with available light situations (if only strong Cloudy sky) to do, as a few millimeters lack of focal length. At some point you have to stop but then times change lenses ;-)
Even at full aperture, the lens produces very good results, all of course under the premise that it is a zoom lens. If you like it even more sharply, must resort to fixed focal lengths, then waived but on flexibility and have to carry while traveling more.
The color reproduction is very good for my taste, as well balanced. If you have a properly calibrated monitor. Chromatic speckles appear only in extreme situations and are usually easy to fix via software.
Distortion has naturally, with this lens, especially at the lower end, which are not pronounced but, as with the (in some cases considerably more expensive) competitors. Distortions, however, are for standard zoom lenses usually not a real stumbling block, here you can always quickly with the appropriate software via correction presets manage automatically or manually. Who photographed eg. A lot of architecture, you should look for an appropriate, specific lens.
(Called at Tamron "Vibration Compensation" or simply "VC") The Anti-Verwackel helper does its job perfectly and is the bottom line of Canon technology in every way. The AF is "conventional", so do not move from one ultrasonic drive. The speed is fine, the operating noise also. Where I shoot any films with my camera. Here, the slight noise could possibly disturb some. The emphasis here is on but "perhaps"!
The Qualitität is absolutely convincing. There is of course no L-lens, for the price, but you get an amazingly robust lens. Just the size and weight are a plus for me. I like to have something in his hand and especially on larger bodysuits one gets with the Tamron good "counterweight". Focus and zoom ring can be turned good, overall "picks" the processed material well.
At the end of the day has to hold you that you get for a small price, a very good look here. The SP AF 17-50mm Di II VC Tamron compares favorably with the more expensive Canon lenses not fear. As an ambitious amateur photographer, to maltreat from practical experience and without any instruments, I see the Tamron in all major categories at eye level to the (usually more expensive) top products in this category. Taking the price into consideration, the Tamron all competitors simply stands out by far. Last but not least it should be mentioned that accompanies a very valued and well-fitting Geli. Canon still does not "create" the.
Again at the end of Note: If you have problems with the AF and / or the general sharpness of the Tamron, should immediately contact Tarmon Germany! I was friendly, helped quickly and without cost in the form of an adjustment especially on my camera! Anyone who has a semi-pro camera (z. B. a 7D), which can also make the adjustment of the focus point mostly self. I do not have the menu item now in the head, just once rummaging through the individual settings.
