The following opinions have been automatically translated with Microsoft Translator. | Sigma 17-50mm f/2.8 EX DC OS HSM Pros: Af fast and quiet, stabilizer, quality / price ratio advantage, housing and hood included Cons: Softness in TA, possible problems of front / back focus, lens hood and cap as a bit 'poor Opinion: I took this lens in place of Tamron 17-50 smooth version, because I felt the need of the stabilizer taking often by hand. I can not say I was disappointed, but the first thing I noticed was the difference in sharpness than the Tamron, Sigma unfortunately is significantly softer at room temperature, is at the center than at the edges, but closing a stop situation fortunately changes, from f5.6 on the sharpness becomes optimal. The stabilizer does work well, does not compensate its fourth stop as stated but still makes a difference. My copy does not seem to have problems sull'af, but apparently it is not difficult to run into a specimen is not perfectly calibrated, probably due to poor quality control on the part of the house, with which the new series, however, seems to have improved the situation . The thing I like most about this is the af ultrasound, fast and imperceptible, compared with the slow and noisy af the Tamron is definitely a nice pasI forward, but mostly does not go into crisis when the light begins to decrease as the Tamron, always manages to hook without major problems. Soft case and lens hood included, which never hurts, even if the quality of the lens cap and attack / hood is definitely improved. Overall it is a very valid objective, solid and well built, with a remarkably affordable price. sent on October 16, 2015 |
 | Sigma 50-150mm f/2.8 EX DC HSM Pros: Quality / price ratio, weight, af fast f2.8 aperture, internal focusing Cons: Limited compatibility with aps-c size, softness to 150mm, slight vignetting Opinion: It is a short telephoto of excellent quality, a lens very valid but strangely not very widespread, there are so few around that has become hard to find. From the exit of the next model comes with stabilizer, the price of the previous version has been significantly reduced making it very attractive. Probably has a focal length a bit 'unusual compared to most telephoto lenses on the market and less curious, but considering it is a lens designed for use on APS-C format, with the crop factor you get to optimal focal lengths (80- 240mm of canon), going almost to equal the alternatives much heavier and above all much more expensive. The constant f2.8 aperture and aperture to 9 blades give a good yield on blurred, is a lens mainly portraits, but manages to be versatile on other uses. A ta is not too soft, the sharpness is already very good, closing one stop becomes exceptional. A slight decrease in sharpness you notice extending thefocal, focal species to the maximum, but it is a common thing. A 50mm is felt just a slight vignetting, but this is something fixable. Suffers a little 'flare, when shooting backlit sometimes creates halos annoying, but nothing dramatic. The af ultrasound is lightning. The building looks pretty solid, non-slip finish of sigma instead I find unpleasant, as well as the attack of the hood, impractical and cumbersome. I think it's worth a try, at least for me it was a pleasant surprise, if you can not find the right price and in fair condition. sent on October 08, 2014 |
 | Tamron SP 17-50mm f/2.8 XR Di II LD Pros: Price, f2.8 aperture, low weight, lens hood Cons: Front / back focus, softness in ta, construction plasticky Opinion: It's a great lens that offers the advantage of a fixed aperture f2.8 and a good sharpness at a very advantageous price, is now used under 250 euro and I would say that overall worth plenty of that figure. Has its flaws, such as building a bit 'plasticky that conveys a feeling of lack of solidity in the hands, the focus a bit' slow and rather noisy, some specimens suffer from front / back focus, but nothing that you can not manage once taken confidence and learned to know him. Perhaps it is a bit 'soft edges to f2.8, and tends to increase the focal length by stretching, but this is a flaw bearable, we say that the whole manages to achieve satisfactory results with a negligible expense. sent on August 20, 2014 |
 | Canon EF 75-300mm f/4-5.6 III Pros: Price, focal length, solid construction Cons: Lack stabilizer, focusing slow and noisy Opinion: It is an excellent telephoto lens for those who begin to experiment with the focal length, the price at which I would say is that is just fine. The zoom range is large, you can cover more or less all need to zoom. The focus is fairly accurate, but it is definitely slow and noisy, but the real sore point is the lack of stabilizer, which can be heard on this type of goals. A 300mm sharpness suffers a bit 'but overall the quality is acceptable. The construction seems solid enough, the bayonet is made of metal and not plastic like other objectives canon in its price class. The professionals who need the stabilizer and an aperture diaphragm greater definitely not would choose, but for everyone else it seems a good compromise, considering the price. sent on June 03, 2014 |
 | Samyang 14mm f/2.8 IF ED UMC Aspherical Pros: Price, brightness, quality construction Cons: Noticeable distortion, exif data, inability to mount filters. Opinion: It is a wide angle lens of rugged construction, the ratio quality / price excellent. The manual focus is not a problem in the focal so short, perhaps the distance scale is not the most accurate, who works with the hyperfocal needs a little 'attention and definitely shooting in live view. One thing to consider is the inability to mount filters on the aspheric lens and the fixed lens hood, the lens is very bright and it gets a bit 'more difficult to handle in long exposure shots. The distortion to "whisker" is obvious, but can be corrected in post. Overall it is a great ultra wide lens, can not be beat for the quality / price ratio. sent on May 27, 2014 |
 | Canon 450D Pros: Price, 3 "display, weight Cons: Building a bit 'plasticky, excessive noise, iso Opinion: It's a great machine for people like me who are beginners, simple and intuitive to use, and at the same time complete in all its functions, the 3-inch display is very bright, it also has the live view mode. It is a machine light and easy to grip, but after having picked up bodies like the 60d or higher models, it is very "toy". The quality of materials is perhaps not of choice, the plastic will wear out easily, but the price to where it is today you can not expect much. All in all, the quality of raw files is good, the only flaw noise management already over 800 iso. Limited sensitivity to 1600 ISO, but it would be unthinkable to go further, the noise would become unmanageable. Once you get a little 'experience can begin to be felt limited, but is great for practice. sent on May 23, 2014 |
