Cons: Soft in corners at 2.8. AF struggling in dark and non contrast areas.

Pros: Excellent from f4 to f8. Not heavy and pleasure to travel with. Ideal for street photography and portraits.

Summary: Best compromise value for money. Excellent sharpness from f4 to f8.

Cons: After about 1 year of use this lens quit focusing properly.

Pros: Amazing image quality for the price.

Summary: This was my favorite lens until the focusing issue started. I contacted Tamron and being I bought it used there was no warrenty on the lens even though it was less than 6 years old, which is the length of Tamron's warranty. This must be a common problem, as the CS rep. I talked to knew the problem and fix immediately. I know another photographer who had the same issue, but she bought hers new so Tamron will fix the problem. This is a wonderful lens, but my advise is buy new, not used.

Cons: Feels plastic but build quality is great. At F 2,8 slightly soft on the edges but from F4 it's getting sharper. 28 mm. is not that wide nowadays.

Pros: Focus to 33 cm. 2,8 from 28 to 75 mm. Light weigt and not too big.

Summary: Looks plastic fantastic but after ten years of intens use it works still great. I use it on 35 mm and full frame digital for all sorts of asignments and my costumers are pleased with the results. I have this lens for ten years at a cost of 350 Euro so that is 35 Euro/year. I shot a great deal of work with it so the cost per picture is very little.For me its a real winner.

Cons: Lot of plastics, some stiffness when zooming.

Pros: One of best quality/price ratio lens ever tried before. Has just some vignetting at f/2.8 on FX and very minor pincushion distortion on FX. Very very good, also considering moderate price target.

Summary: Construction could be better, but this is one of best examples of value for money.

Cons: the zoom-tube could be less sticky, AF slow, plastic-fantastic

Pros: EXCELLENT imagequality, best walkaroundzoom (even better than Canon L 24-105 IS), fantastic prize-quality relacion

Summary: A very nice walkaround-zoom for a really cheap prize, matches much more expensive lenses, really nice macro, good colours, clean - what you want more? This is the "real" Tamronlens, much better than the SP 17-35 and even better than the 17-50 f2.8. The plasticconstruccion is alright for the prize....

Cons: poor build quality, not always precise AF

Pros: sharp on all apertures, acceptable size for such fast aperture lense, price

Summary: Very good lense for the price with great optical quality.

Cons: - bad quality control

Pros: - great picture quality - excellent sharpness - fast AF - no chromatic aberration - warm and vivid colors - nice price

Summary: very cheap and one of the best portrait lenses

Cons: it is not a nikon... sometimes the D700 misses exposure, especially with the internal flash. must often compensate, while with nikon lenses it is always on the spot.

Pros: incredible for the price, lightweight. f2.8 is acceptable, f4 excellent. the best walkaround lens you can get for a D700.

Summary: not a stellar performer, but a VERY useful lens. for the price, no ff shooter can do without. it allows shooting ff for almost the weight of a dx.

Cons: slight zoom creep, 24-75mm will be best, a bit slow focusing, opposite direction of zoom in-out (not like canon), No stabilazer.

Pros: Prise, Good resolution, matching canon EF24-70mm in image and colors, Very sharp in f4-f8, Light 500 kgms, Good for Macro.

Summary: I have been very worry abut buying this lensce, but consitering the price i when for it. I have very good pic with the lensce. Highly recommended.

Cons: AF is not blazingly fast but it isnt a big issue

Pros: everithing else

Summary: Its a fntastic lens for the money!!

Cons: Nothing i saw so far

Pros: Sharpness in a good price.Same IQ to nikon but this one is cheaper

Summary: i totally recommended this lens. Nothing can compare. i already try mostly all the same range in differrent brands

Cons: - Soft at 2.8 - ghosting at 2.8 - Flimsy feel of build (But I am comparing it to N's 16-35&70-200 II) - 28mm not "that wide" on full frame anymore. - Light weight (I like the feel of a substantial lens)

Pros: - Screw drive version is very fast to focus and very accurate in all but dimmest light. - Really sharp at f/4-f/8 - Light weight (yes a pro too. A great back up/travel lens if you have pro gear).

Summary: At $350 it's hard to tell f/4 from a Nikon pro zoom. I can tell, but cutomers can't. I consider this a straight f/4 lens. So $350 for a 28-75 f/4 is not bad. I would prefer it to be much shaper at 2.8, but can't complain for the price you pay. Micro contrast isn't as good as Nikon's 24-70 and doesn't quite resolve fine detail the way the pro glass does, but again, it's extremely usable and it's cheap. I wouldn't reccomend it for heavy use, but to have a light, cheap 2.8 in your bag, you can't beat this. It performs just about the same as the Sigma 24-70 HSM, but for half the price. As the saying goes, it's 9/10 the optical quality of the Nikon version, but at 1/5 the price.

Cons: It's slightly soft at f2.8 than the L-equivalent. Its auto-focus is a little noisy and slow. The way it is built is a little plastic. 28mm is not very wide on APSC but quite good on FF.

Pros: Sharper (eye-cuttingly so) than the L-equivalent once stopped down slightly, to say f4-f5.6 before diffraction effects creep in. It's super light for such a fast lens and super cheap.

Summary: The pros of this lens easily compensate for its shortcomings. The lens, after some experience, is more than capable of producing excellent shots for a fraction of the price.

Cons: If you want to pick on the build quality. Tends to be slow focusing

Pros: Fast lens , compact, price.

Summary: Shot bands even high school in-door sports. If you can only afford this lens, you will not be disappointed. Love mine and still us it.

Cons: The inner focusing tube wobbles - makes one feels uncomfortable, though the subpar construction does not seem to affect performance. No stablization.

Pros: Good resolution, matching that of prime lenses at optimal apertures of f5.6-f8.0. Not overly large.

Summary: Good and much smaller and cheaper alternative for full-frame camera - Been using it on a Canon 5D.

Cons: a

Pros: a

Summary: a

Cons: Very slight zoom creep. Mild softness at f2.8

Pros: Very good image quality f4 through f8. Full frame or APS-C. Zoom lock.

Summary: Outstanding value when considering price to performance.

Cons: Could be sharper at the long end @ f 2.8 (from 60-75mm) Vignetting clearly visible, even when stopped down to 5.6 AF not as fast as ASF Nikkors (not that slow either)

Pros: Fantastic sharpness/contrast across the frame. Matches or even outmatches much more expensive pro lenses. Natural color rendition

Summary: I'm excited by the performance of this small and light Tamron (BIM-Version) on my Nikon D700. It's a bit too soft at the long end wide open but things improve rapidly by stopping down to 3.5. From f4 onwards the lens is amazingly sharp across the entire frame. Strangely it doesn't perform that well on my Nikon D90.

Cons: A bit soft at the long end (65-75mm) at f2.8 in my case, not extremely fast when autofocusing (=not for the "sport-" or "wildlife"-shooter, but more than good enough for everyone else), not weather sealed (but cannot be expected at this price tag),

Pros: Very good optical quality on EF and EF-S mount, very cheap lens, f2.8 over the whole zoom range, good built-quality.

Summary: Worth every penny. A very cheap alternative with impressive optical quality to some expensive Canon lenses. Highly recommended.
