Tamron 18-250mm f/3.5-6.3 Di-II LD
8 May 2009
Conclusion: The Tamron is a capable superzoom that delivers adequate results when used carefully. Its versatility is impressive, but you should be aware of its restrictions, such as the maximum aperture of f/6.3 from 200mm. It’s best use will be as a travel lens, where its range and compact size are advantageous.
Conclusion: I was actually quite surprised by the performance of this lens. I didn't really expect a 13.9x zoom to be very good, and indeed it does have some limitations, but it did better than I expected, especially at the wide end of the range. The consequence of squeezing such a wide optical range into such a small physical package is that some optical compromises must be made. The lens isn't fast at the long end. It's f6.3 from 200mm to 250mm.
Excerpt: Not so long ago the more dedicated photographer/hobbyist who wanted to be ready for any picture taking opportunity carried around a big bag filled with several lenses of various focal length lenses. When I started out in the hobby I carried a 28mm fixed focal length wide angle, a 35-70 for the slight wide angle to slight telephoto photos, a 50mm f1.4 standard lens, a 80-200 f4 telephoto zoom and a 2x teleconverter to turn the 80-200 into a 160-400mm zoom.
Excerpt: While you were out, the digital-only superzoom got more super. Tamron, originator of the superzoom lens more than a decade ago, ups the ante with its new 18-250mm f/3.5-6.3 optic -- boasting the industry's broadest zoom range, at nearly 14X (13.9X). A 28-388mm equivalent, it adds 50mm to the tele end and does so at no cost of weight, dimension, or optical performance over Tamron's 18-200mm f/3.5-6.3 lens (which remains in Tamron's catalog).
Tamron’s AF18-250mm F/3.5-6.3 Di II LD Aspherical (IF) Macro; A 13.9x Zoom (!) For D-SLRs

Excerpt: Although Tamron makes some wide aperture, pro-grade lenses, the affordable "multi-platform" 28-300mm zoom and the "digital only" 18-200mm zoom have been their best sellers. That's understandable, since those are unusually versatile and portable lenses. Now, Tamron is marketing a newer 18-250mm Di II model, the first lens on the market with a 13.9x zoom range, the broadest available.
Conclusion: It’s hard to write such an opinion but I must admit I haven’t tested a similarly weak lens for a very long time. Usually in the summary I try to include something positive about the tested devices – here it is really difficult because the Tamron 18-250 mm looks bad from almost every angle. You can say something good only about its 18-50 mm performance, which is like that of stabilized Canon and Nikon kit lenses.
Cons: very weak picture quality at longer focal lengths both in the center and on the frame edge., dreadful macro mode performance,, noticeable vignetting at the shortest focal length,, the lack of stabilization and poor aperture limits the use of the lens to good conditions only or forces to use high ISO values,, autofocus audible and not very accurate,, distortion significantly pronounced at wideangle,, noticeable astigmatism,, significant chromatic aberration at both end...
