![]() | Canon EF-S 17-55mm f/2.8 IS USM Pros: Sharpness, brightness, IS, AF, full time manual focus, Cons: Price, not including lens hood, vignetting, weight Opinion: Outstanding optical quality, already at full aperture is very clear, and diaframmando become razor sharp even at the edges, the autofocus is impeccable and extremely quiet, the build quality is not great, but it's well-made plastic, decent but not outstanding resistance to flare. On balance it is one of the best lenses specific for APS-C, perhaps the only Sigma 18-35 is superior, but pays the reduced focal range. Compared to my "old" Tamron 17-50 are on another planet has the Tamron AF of a tractor (both in terms of slowness that noise) the Tamron 2.8 is just enough over the edge and you diaframmarlo f4 to have edges decent. The price is a little high in relation to the fact that you do not give it bag it hood and the weight is not from dragonfly! But for the rest it is to be recommended as an upgrade to the sigma / Tamron 17-50! sent on June 01, 2015 |
![]() | Tamron 18-270mm f/3.5-6.3 Di II VC PZD Pros: Ability to use only one objective, without having to make changes and lose the ability to do a particular photo. Stabilizer fairly effective. Cons: For practicality of use you lose a little bit in terms of brightness, the maximum focal length and with a 270mm MAF infinity is but just reduces the MAF you get to about 240mm, which could make him prefer the canon 55-250 Opinion: It may be a good buy for those who need practicality of using a single objective, or to learn, the only coupled 18-55 55-250 is superior. So buying this lens should be evaluated very carefully, if only for the fact that it is not (except with the MAF infinity) a true 270. Recommended as mentioned in newbies to learn without having to constantly change target, or for those who have space problems in having to manage 2 or more goals. sent on October 16, 2013 |
