Professional optics

Since the beginning of 2006 I am the proud owner of the Tamron SP 28-75 XR Di and use it intensively on my Konica Minolta Maxxum 7D. Since I am a semi-professional / commercial photographer in addition, by now several gigabytes of pictures, was able to gain a lot of experience with this appearance I want my personal test results summarize a little here.

First, we can say clearly that the lens a much higher price would be worth it, as such, it is currently being sold. Without exaggerating the benefits of the rich already from Tamron aperture 4 close to the sharpness and brilliance of a fixed focal length zoom. Only when fully open aperture (F 2.8) the performance of the lens falls off sharply and obtained very 'soft-focus' images. For almost the entire zoom range, there is the power out to be significantly more than satisfactory. Only in the largest wide-angle (28mm = 42mm / KB-format) you recognize a barrel distortion, although similar fast means of Photoshop persists. Other artifacts are holding back so far that they are usually not noticed. Chromatic aberration is not an issue since the formation even under extreme conditions hardly fringing to the light / dark edges. Furthermore, the Randabdunklung and the loss of sharpness towards the edge is gone not really noticeable. Referring to the behavior in backlit situations, no fog can be observed as long as the lens hood is attached. Also the processing is on quite a good level, in spite of plastic optics. Only a little shaky mounted zoom ring tarnishes somewhat the Fotografierspaß.

Conclusion: Super lens on the DSLRs from Minolta - at absolutely fair price. In the area of ​​standard zooms through the price hardly beatable. Sharpness and brilliance reminiscent of far more expensive or even zoom lenses. For the professional, this SP version is certainly a highly recommended investment, aiming with their performances in the professional storage of Minolta's G lens and Sigma's EX series. I myself use it as 'always on it' and in the field of portraiture, group and nature photography. 'Even the ambitious amateur photographer, this lens can be quite times closer look, because it certainly is an interesting buy recommendation for him. Beginners, however, have to decide whether they need the same one objective in this price range, and of course their images would benefit from the imaging performance itself. Yet here, less is more and you should take a few steps with the kit lens first. Without someone to come too close - professional equipment makes for a long time no good pictures, it comes down to what makes The one behind it.

Note: As can be seen from several photography forums, Tamron seems to have a large tolerance in the production, since many users are very disappointed after purchasing. Especially with the lenses -'Made in China 'was frequently re-adjustment necessary. However, if his Tamron sent in for servicing to Cologne can look forward confidently to get it back. After reworking Everything is perfect and as desired. So who detects an incorrect focus or want the focus clearly leaves something which should be equal to replace the lens or repaired 'it is worth!
