Tamron SP 17 50mm F 2 8 XR Di II VC Análisis | 54 Datos comparados

The-Digital-Picture.com's review of the Tamron SP AF 17-50mm f/2.8 XR Di II VC LD IF lens highlights it as a value-oriented, stabilized alternative to high-end lenses, boasting a highly effective 4-stop Vibration Control (VC) system for low-light, handheld shooting. While offering decent center sharpness at f/2.8, the lens serves as a capable, budget-friendly option for photographers prioritizing stabilization, according to the analysis. Conversely, the review finds that adding VC resulted in significant optical compromises, particularly noticeable soft corners when shooting wide open at f/2.8, which necessitate stopping down to f/4 or f/5.6 for better edge-to-edge performance. Other disadvantages include moderate to heavy vignetting, loud autofocus and VC operation, and overall softer image quality compared to the non-VC version of the same lens.

summary of the lens review: The Tamron 17-50mm f/2.8 VC is a constant-aperture standard zoom lens designed specifically for APS-C crop-frame cameras, offering an effective focal range of 26-75mm on Nikon bodies and 27-80mm on Canon bodies. A major benefit of this lens is its optical performance when stopped down, showing excellent center sharpness at f/5.6 and optimal performance across the frame by f/8. It also boasts highly improved distortion control, with barrel distortion at 17mm falling to 0% between 35mm and 50mm. Other pros include a functional zoom lock switch to prevent zoom creep, low corner shading by f/5.6, and a non-rotating front element that makes it easy to use polarizing filters. However, the addition of the Vibration Control (VC) system introduces notable drawbacks, as the lens suffers from inferior sharpness, weaker chromatic aberration resistance, and worse vignetting compared to its older, non-stabilized predecessor. When shot wide open at f/2.8, there is significant corner softness at the wide end and overall central softening by 50mm. Additional cons include a heavy, mostly plastic build, autofocus performance that is slower and...

The Tamron 17-50 mm f/2.8 DII VC SP XR LD is a fast, versatile zoom lens designed for APS-C sensor cameras and serves as an excellent upgrade over standard 18-55mm kit lenses. Its standout feature is the built-in "Vibration Compensation" image stabilization, which offers about 3 stops of effectiveness for smoother handheld shooting. Built with a solid, play-free zoom ring and a quick, low-light accurate autofocus system, the lens delivers high to very high resolution across the center of the frame at all apertures. Additionally, chromatic aberration is well-controlled, and vignetting becomes negligibly low once stepped down past f/2.8. However, the lens does come with several distinct drawbacks that users must consider. Its optical resolution lags behind significantly in the corners compared to the sharp center, especially at focal lengths of 28mm and 50mm. The bokeh is often considered unappealing because the blur circles are heavily plagued by harsh rings. Furthermore, the lens shows heavy distortion at 17mm and is highly sensitive to strong backlight, which easily produces flare and ghosting. Finally, manual focusing is difficult due to a very...

The Tamron SP AF17-50mm F/2.8 XR Di-II VC LD Aspherical (IF) Review by Darrell Young highlights it as a highly reliable, budget-friendly zoom lens specifically optimized for Nikon DX sensor (APS-C) cameras. The reviewer strongly praises its constant f/2.8 aperture, which enables superior low-light performance and reliable autofocus acquisition during challenging event photography, such as dark wedding receptions. A standout technical asset is Tamron's proprietary 3-axis Vibration Compensation (VC) system, which provides superior diagonal shake protection and a faster, tighter visual lockdown compared to Nikon's standard 2-axis VR system. Optically, the lens demonstrates exceptional sharpness across all apertures down to f/11, highly controlled chromatic aberration, and zero noticeable distortion between 24mm and 50mm. Despite its professional-grade optics, the review points out a few explicit limitations. The physical construction relies primarily on plastic; while described as strong and robust, it does not match the heavy metal build standards of premium Nikkor lenses. Optically, the lens suffers from visible barrel distortion at its widest 17mm focal length. Extreme lighting tests also reveal mild edge softness and slight corner light falloff when shot...

The Tamron SP AF 17-50mm f/2.8 XR Di II VC is a compact standard zoom lens designed for APS-C format cameras, serving as a direct, budget-friendly competitor to Canon's 17-55mm f/2.8 lens. A major highlight of this revamped lens is its highly effective built-in Vibration Compensation (VC) system, which provides four stops of stabilization—outperforming the three-stop stabilization found on the rival Canon model. It features a constant f/2.8 max aperture throughout its zoom range, which is slightly shorter than Canon's by 5mm at the long end. Optically, the lens incorporates Extra Refractive (XR) and Low Dispersion (LD) elements to control distortion, helping it deliver excellent center-sharpness that peaks when stopped down to f/4 or lower. Despite offering great overall value, the lens has several handling and physical drawbacks. Its autofocus system relies on an old-fashioned electric motor that is relatively noisy and causes the focus ring to rotate during operation, forcing users to keep their fingers clear or switch manually to manual focus mode. Additionally, its zoom ring operates in the opposite direction of native Canon lenses. In terms of...

The Tamron SP AF 17-50mm f/2.8 VC XR Di II LD is a high-performing, cost-effective alternative to native standard zoom lenses, offering excellent center sharpness and a highly effective Vibration Compensation (VC) system, according to a review by ePhotozine. Key advantages include its versatility for low-light shooting and the ability to capture sharp handheld images at slow shutter speeds.
