The following opinions have been automatically translated with Microsoft Translator. | Canon EF 70-300mm f/4-5.6 IS USM Pros: Autofocus, stabilizer, sharpness, weight, dimensions Cons: On my specimen the rotation of the ring to vary the focal length is a bit 'too rigid Opinion: Bought used and paired with a Canon EOS90D and an EOS2000D. Obviously it does not have the quality of the most recent and expensive optics but still defends itself well (for the type of photography I do, mainly dynamic subjects, cars, planes, birdlife). The AF is accurate, fast and quiet, I do not find the noise described by others. The stabilizer is very good, stabilizing the image well even pointing at fast-moving subjects. Combined with the 2000D it has a strong vignetting that has disappeared by combining it with the 90D (sometimes there are unhappy combinations between machine and lens, it is not the first time that I hear of problems that disappear simply by combining the lens with another camera body). On my specimen, however, the rotation of the ring to vary the focal length is a bit too rigid and sometimes tends to make small shots. This is the only flaw detected on this lens (and that is probably just mine). All in all he always gave me good quality images and overall I am more than satisfied. sent on May 03, 2022 |
 | Tamron 100-400mm f/4.5-6.3 Di VC USD Pros: Nobody Cons: Unresponsive and inaccurate autofocus, non-existent stabilizer, strong vignetting, chromatic aberrations Opinion: Used for more than a year in combination with a Canon EOS90D for dynamic subject photography (cars, planes, birdlife) Weight and dimensions are in line with the same focal lengths of other brands. The stabilizer is practically non-existent, you have to continuously press halfway on the shutter button to hang up the subject but every time the stabilization is lost immediately. The autofocus is poorly responsive, it cannot follow the movements of fast objects and when it succeeds the subject has already left. Often the autofocus goes into lockdown and even pointing to a well-defined and distant subject does not move, in addition to the fact that every now and then it goes crazy and slides back and forth the entire focal length. I also noticed these flaws on another Tamron lens, an 18-200, so the only solution is to turn the camera off and on again. Problems I never had with original Canon lenses and are the reason why I consider my experience with Tamron lenses over. Chromatic aberrations are present, but these can be corrected in postproduction. The vignetting is very strong already observing the photos normally, if you then do the equalization of the photos you realize the phenomenon. It is not very bright, but for the money it costs you can not expect better. Suitable only for photography of static subjects. It is not worth the money it costs, I do not recommend it. sent on May 03, 2022 |
