I use the Tamron on a Nikon D700. My requirements for a high image quality is extremely high because of my otherwise exclusive use good lenses. Overall, my Tamron 70-300mm VC like it very much. The following reasons lead to this judgment:
1 Image Stabilizer: this works great. Without any problems I can still expose a 30th of second, and camera shake at 300mm.
2. Autofocus: He's not the fastest, but - at least in my copy - all apparently very precisely and accurately, even in poor lighting conditions
3. focal length range: While this is a very individual thing, but I find the focal length range very well! The difference between 70 and 300mm is already huge, between 200 and 300mm is happening not bad lot. A zoom lends itself at the telephoto end simply because you will be less flexible with longer lenses.
4. Sharpness: Of course, the image sharpness never comes close to that of a good fixed focal length. The 12-MP sensor of the D700 seems to be fully resolved at any time. BUT: The sharpness is also at maximum aperture very useful (particularly at 300mm!), Dimmed can hinbekommen really quite good results.
The build quality is absolutely ok. Disturbing is the great sun visor.
But what prevented the lens, the 5-star rating?
The exposure.
I do not know why, but I have about a 2/3 stop more exposure than my other lenses to obtain the same brightness and a balanced exposure. If the bar on the exposure scale in the middle stands, the picture is clear underexposed.
I find that very annoying because you have to constantly pay attention from now on that you also yes somewhat more exposed. While you can just use the exposure of the camera for this, but at the latest when konstrastreichen scenes spot metering has ran or specific emphases of exposure are needed. The Tamron with its underexposure difficult this project. For a star deduction.
Distortion increases from 70 to 300mm to constantly and requires a correction in architectural photography. Dramatically, this distortion is not.
Conclusion: Would not the underexposure, the new lens from Tamron deserves full five points. It is sharp, has a great image stabilizer and focused reliable. For this, the price is okay.
