Tamron SP 28 75mm F 2 8 XR Di Análisis | 54 Datos comparados

The Tamron SP 28-75mm f/2.8 XR Di AF is a highly compact, lightweight, and budget-friendly medium-range zoom lens designed as an alternative to pricier professional Nikkor lenses. Constructed primarily from durable polycarbonate with a metal mount, it features a constant f/2.8 maximum aperture that provides bright viewfinder images and excellent low-light autofocus performance. The lens delivers rapid, accurate autofocusing with virtually no hunting, smooth zoom ring mechanics with zero zoom creep, and a non-rotating front element during use. Optically, it provides excellent sharpness at all focal lengths when stopped down, neutral to warm color rendition, and exceptional contrast and flare control. Despite its benefits, the review highlights several distinct drawbacks. When used wide open at f/2.8, the lens lacks the edge-to-edge sharpness found in comparable Nikkor alternatives. Additionally, manual focusing can be tricky because the focus ring requires an extremely short 45-degree rotation to travel from its close-up limit to infinity. The manual focus ring also rotates clockwise toward infinity, which is the opposite direction of standard Nikkor lenses. Optical distortion is another weak point; while it shows only slight...

The-Digital-Picture.com highlights the Tamron AF 28-75mm f/2.8 XR Di LD as a compact, value-oriented standard zoom lens offering solid, well-damped build quality and rapid, short-rotation manual focus/zoom adjustments. Key advantages include its lightweight design and cost-effectiveness compared to first-party f/2.8 lenses, though it sacrifices fine, precision focusing capabilities. Drawbacks noted in the review include control rings that lack optimal grip and a reverse-direction rotating zoom ring that operates opposite to standard Canon lenses, which may hinder usability. While functional, the lens's design choices result in a trade-off between handling ergonomics and speed.

The ePhotozine review of the Tamron SP AF28-75mm f/2.8 XR Di LD Asp IF Macro highlights the lens as an outstanding, budget-friendly optic that delivers sharp images, particularly at the 28mm end, with peak performance at f/8. While resolution dips to softer levels at the 75mm end, stopping down to f/11 restores corner-to-corner sharpness, complemented by excellent chromatic aberration control. Physically, the lens features a compact, lightweight polycarbonate build with effective close-focusing capabilities (33cm). Key disadvantages identified include a noisy, slow micro-motor autofocus, a very limited 45-degree manual focus ring throw, and a lack of built-in image stabilization.

The Photo Review evaluation highlights the Tamron SP AF 28-75mm f/2.8 XR Di LD Aspherical [IF] lens as a compact, affordable constant f/2.8 zoom, offering excellent center sharpness and effective aberration control for both full-frame and APS-C sensors. Key advantages include its lightweight build, internal focusing for polarizer use, and strong performance at 28mm. However, the review notes reduced sharpness at the 75mm end, minor vignetting at wide apertures, and a relatively slow, noisy autofocus motor, along with a lack of image stabilization.

The Tamron SP AF 28-75mm f/2.8 XR Di LD Aspherical (IF) Macro (Model A09) is a budget-friendly, lightweight, and compact standard zoom that provides a constant f/2.8 aperture suitable for both full-frame and crop-sensor Nikon cameras. Key advantages include strong center sharpness when wide open, enhanced performance at smaller apertures, and, according to Radojuva, a useful 33cm minimum focusing distance with low-dispersion glass to manage chromatic aberration. Conversely, the lens suffers from notable cons, including noisy, slower autofocus and the lack of a built-in focus motor in older versions, meaning it will not autofocus on entry-level Nikon D3xxx/D5xxx bodies. Additional disadvantages mentioned include heavy vignetting and soft corners at the 28mm wide end, a reverse-rotating zoom ring compared to native Nikon lenses, and potential quality control inconsistencies in used copies.

The Tamron SP AF 28-75mm f/2.8 XR Di is a compact, highly affordable, and fast constant f/2.8 mid-range zoom lens designed for full-frame cameras. Released in 2007, it delivers impressive central image sharpness even wide open at f/2.8, which becomes exceptionally high across the entire frame when stopped down to f/5.6. At f/2.8, it produces a beautifully circular, creamy bokeh. Chromatic aberration is well-controlled, and its 33cm close-focusing distance allows for excellent close-up capabilities. Its primary advantages are its highly competitive purchase price, fast maximum aperture, exceptional central sharpness, and low overall distortion. However, the lens has notable compromises in its physical design and optical performance. It lacks built-in image stabilisation, and the mechanically driven autofocus is both slow and noisy, occasionally hunting in low light. Optically, it suffers from heavy vignetting at f/2.8—particularly at the 28mm wide end—as well as visible corner softness wide open. It is also prone to flare and ghosting in backlit environments. Finally, the zoom range is somewhat limited at the wide-angle end, and the short focal stroke makes manual focusing difficult.

The Tamron SP AF28-75/2.8 XR Di LD Aspherical (IF) Macro is an exceptionally highly-regarded, affordable standard zoom lens that delivers very strong optical performance across its focal range. It is heavily praised for its impressive center sharpness even when shot wide open at f/2.8, with optimal peak performance reached when stopped down to f/4 or f/5.6. In terms of physical advantages, the lens boasts a lightweight and incredibly compact build that saves about a pound in weight compared to massive pro alternatives like the Canon 24-70/2.8L. Additionally, it exhibits superb control over chromatic aberrations and is highly resistant to image-degrading flare, comfortably outclassing popular consumer zooms like the Canon 28-135mm. However, the lens does come with some notable drawbacks that users must consider before purchasing. While it serves as a highly versatile mid-range option, its overall focal versatility is slightly limited compared to broader consumer zooms, and it completely lacks built-in optical image stabilization (IS). Performance at the widest apertures also leaves a bit of room for improvement; edge sharpness is noticeably soft at f/2.8 across all focal lengths, meaning...

The Tamron AF 28-75mm f/2.8 SP XR Di LD Aspherical (IF) is a highly popular, budget-friendly standard zoom lens designed primarily for classic full-frame DSLR cameras. A key highlight of this lens is its remarkably compact "dwarf" size and lightweight 510g build, achieved by using two Extra Refractive Index (XR) elements that bend light more efficiently than standard glass. It belongs to Tamron's professional-grade "Super Performance" (SP) lineup and features an internal focusing (IF) design, meaning the 67mm filter thread front does not rotate during operation, making it excellent for polariser filters. It offers a close minimum focusing distance of 0.33 meters and a useful zoom lock switch at 28mm. In terms of performance and construction, the review highlights distinct pros and cons. The primary advantages include its very affordable price point, stellar performance on APS-C crop sensor cameras, and a smooth operation of both the zoom and focus control rings. On the downside, the review notes that the finish and material quality feel less premium than competing professional lenses from Canon or Tokina. Additionally, the physical lens barrel extends...

The Opticallimits review reveals that the Tamron AF 28-75mm f/2.8 SP XR Di LD Aspherical (IF) delivers exceptionally high optical performance for its price league when tested on an APS-C DSLR. Its key pros include generally excellent central resolution with borders that follow closely, very low vignetting across all apertures, and well-controlled chromatic aberrations. Distortion is also highly commendable for a standard zoom, exhibiting only medium barrel distortion (~1.5%) at 28mm, marginal distortion at 40mm, and minor pincushion distortion (~0.4%) at 75mm. Conversely, the review highlights notable cons regarding production consistency and construction quality. The lab noted a worrisome centering defect at large-aperture settings on the wide end of the zoom range, which was present in both samples they tested. Additionally, the mechanical build quality is described as merely decent rather than impressive, and the focal range can feel somewhat odd or restrictive when constrained to the cropped field of view of an APS-C sensor.
