How does it compares with its competitors? Both Canon and Tamron give more even results, with smaller differences between the maximum and the minimum aperture. You might notice that these differences are so slight because of two factors: one positive and one negative. Firstly, maximum focal length and f/2.8 results are a tad better than Nikkor’s, because Canon and Tamron reach 32lpmm, like Nikkor, but only while working with a 8-megapixel matrix of Canon 20D. On the other hand, their maximum achievements, reaching 40-42 lpmm, even if we take into account the difference between the pixels density level, aren’t as high as Nikkor’s, which can reach even 46-47 lpmm.
To sum up: in the frame centre Nikkor 17-55 mm gives us exactly what should be given by a professional lens – a great picture quality in full range of apertures and focal lengths.
The lack of failures here is praiseworthy indeed. In the full range of apertures and focal lengths Nikkor has results exceeding 30 lpmm so there are hardly any reservations to be expressed. Only one combination of the focus 55mm and f/2.8 gets the result of 29 lpmm so a bit under 30 lpmm. Taking into account the fact that the measurement errors reach here almost 1 lpmm we can turn a blind eye to this fact with understanding.
When we start comparing with the competitors, Nikkon gets even more praise. Tamron 17-55 clearly loses when it comes to maximum aperture, with the results of 20 lpmm level. Canon 17-55 mm f/2.8 is better than Tamron but still worse than Nikkor – for the maximum aperture it gets not more than 30 lpmm. Its best results for the frame border reach only 33 lpmm whereas Nikkor reaches even 38 lpmm. Again, even if we take into account the difference between the pixels density level of the different matrixes, Nikkor wins.
George ik heb er lang genoeg over kunnen nadenken plus dat ik deze lens een week op mijn camera heb gehad en heb er goede resultaten mee gehaald vol open.
Dannog alleen scherpheid is nog niet alles wat een lens nodig heeft.
