It is not in this case certainly one of the brightest models in the market and the relatively large focal length makes the choice of a very small aperture often necessary. In order to stabilize this lens on a crop camera still enough without blurring the same, shutter speed is about 1/500 sec necessary if you go to the generally accepted rule of thumb (1 / (focal length * crop factor), here.: 1 / (300 * 1.6) = 1/480). Depending on the selected aperture is needed here quite a bit of light to get a sharp photo. This lens to choose the maximum aperture, as often as not really good idea, because the image quality suffers noticeably. Therefore, an application example only at the next visit to the zoo in the sunshine makes sense.
The imaging performance even tears in my opinion, no trees, but that is expected at a lens of around 130 euros be obvious she was very noticeably developed for beginners and casual photographers who like to do on the weekend with the family a trip. For a lens in this price range, the processing is actually surprisingly good.
Negative, I judge, however, that this objective apparently no polarizing filter may - at least in my autofocus failed completely his service.
My Conclusion:
If you get this lens in the so-called Canon Double Zoom Kit, along with an entry-level DSLR and a 18-55mm IS II just again, you may like to strike. For me personally it has not really been a pleasure, as the restrictions are just too severe. But what were the alternatives? Beginners, I would rather recommend the Canon 55-250mm 4.0-5.6 IS II. Let me briefly explain why:
From the Aperture ago both lenses are very equal. The image quality does not differ dramatically. The 50mm more obenrum by the 75-300mm you will definitely not miss in practice. Looking at the differences between 250 and 300mm when 75-300mm, it soon becomes clear how ridiculous this is little reserve. The 20mm untenrum there are already noticeable. But the great advantage of 55-250mm lies clearly in its Image Stabilizer (IS). If you need a minimum of approximately 1/500 sec. Shutter speed with the 75-300 without IS, these are the 55-250mm IS without approximately 1/400 sec. Take the IS with this, you will need approximately only 1/100 of a second ( Here: two stops slower shutter speed; also the focal length is slightly less) to get any blur. At the current price difference of 10 euros (!) I would definitely take the 55-250mm.
