The price was for me the reason not a lot of this "glass" to be expected. "Good times lenses now cost money". This one has already told me unanimously twenty years ago. Nevertheless, I have been pleasantly surprised by the Tamronobjektiv.
The price a lens hood is included. A first advantage of the Tamron. The lens cap is, especially the, 1a for the front. The build quality and the feel of the lens is very good for this price range. The 70-300 clutches his dibasic. Nowhere is a game to determine (such as in my OriginalKit 18-55 of Pentax). The bayonet is made of metal. The iris adjustment engages clean. The rotational surfaces are rubberized. When zooming the lens gives a "rich" spinning sensation without being stiff. Tamron has built much plastic at 70-300, which the weight is of great benefit.
The AF sits comfortably and safely. To what extent lenses from other manufacturers because better I do not dare to judge. However, so much faster and more secure, it may no longer be in this price range. The first images were very clear and sharp. The Tamron reputed, excessive color fringing so far I could not tell so. However, I use a polarizing filter on the lens.
Also, I find the "Macro function" of the objective class. Until Abbildungsmasstab of 1: 2, the Tamron delivers crisp, sharp images. A switch limitate here the focal length range by a good Minimum focusing distance achieved.
Supplement 07/08: The Tamron is my most used lens. Of course it would give hochertigere lenses that would considerably enhance the imaging performance with safety. Above all, a stronger light option would in the higher zoom range but very helpful. Alerdings these optics are in the five- to seven-fold cost range of Tamron. The Tamron reputed color fringing occurs with very high contrast. This can be but good deal, or the situation considered with a little resolve different (background, etc.). I think the Tamron for the price continues to mercilessly well. Especially for transfer passengers to the DSLR technology, the Tamron lot for little money.
Supplement 01/09: Meanwhile, has also joined the high-intensity 70-200 / 2.8 to my equipment. In direct comparison provides the here-reviewed "Low Budget Tele" really handsome. That can not keep it in poorer light or moving subjects clearly. In comparable circumstances and identical setting, it may compete well in the field. In the area around 200mm it depends my Tamron "travel zoom" 18-250 in sharpness from even.
Conclusion: Where else gets only a used lens for the money obtained with the Tamron is a quite useful, recommended and full telephoto zoom with a large focal length range, a good optical performance and Macro function. And with warranty.
