![]() | Tamron SP 17-50mm f/2.8 XR Di II LD Pros: Sharpness, price, availability, warranty (5 years), brightness Cons: At this price? NONE Opinion: I was not to buy this objective because of opinions more or less marked on focus, noise and construction. Luckily I changed my mind and not a little. Although it may be agreed that the autofocus is noisy I also understand "compared to what" all this noise does not perceive, remember the Canon 50mm f/1.8 that will surely be felt, but from the reviews that you read I was ready to buy earplugs ... Rest assured it is not. The noise remains the standard of a USM motor and the same can be said for accuracy. As soon as I got the lens I tested the three batteries to check F / B Focus, well precise as a clock. The test was performed in a small room with two bajour lit desk, difficoltà.rnPer without regard to building the rings are accurate and robust, the lens hood has a great groove and the lens has a good weight in case of the undersigned perfectly balances the EOS 50D. Is notsealed, I can not insert it between the "against" because in this price range (277 € sull'Amazzone with 5 years warranty) would be an exaggeration to claim it. The plastic dominates but definitely still gives feeling of strength and solidity, for instance does not seem a plasticotto that you can break at any moment. RnDa praise the sharpness and image quality in general, fantastic and unexpected, you just look at the photos taken with this lens here or on other photo sites to get an idea. rnrnGiusto for the record I own in a kit Canon EF 17-40L, Canon EF 50mm f/1.8, Canon EF 24mm f/2.8, Canon EF 75 - 300 I recently sold a Canon EF-S 17-85 and a Canon EF-S 18-55 IS II so it's not that I have never tried lenses before. rnrnBasandomi direct experience doing so pretend I did not never read anything about this little gem (to erase all forms of prejudice) I can confirm the good in everything and the quality / price ratio superlative. If you need something brightnessknow and sharp in this range of focal lengths there is no reason for not recommending it, take it with your eyes closed. sent on March 31, 2013 |
![]() | Canon EF-S 17-85mm f/4-5.6 IS USM Pros: Focal length, construction, AF, stabilizer Cons: Lack of sharpness, chromatic aberration, very dark Opinion: I've used it primarily as an objective "all-rounder" travel. Apart from the AF fast and accurate enough have never been satisfied by the quality of the images. I was able to test it thoroughly on a Canon 50D and a 300D, with results below expectations. The clarity is low, closing at f8 f9 improves slightly, but need to increase the shutter speed dramatically. In situations of conflict chromatic aberration is very obvious, not always in PP are able to improve it. I would not recommend it unless it is at a bargain price and you do not have big needs in terms of quality. sent on March 25, 2013 |
