• Tamron Zoom Wide Angle-Telephoto AF 28-75mm f/2.8 XR Di LD Aspherical (IF) Autofocus Lens
Reviewsamstel78's Full Review: Tamron A09 for Nikon
Build quality from an aesthetic standpoint though is rather good, with the plastic bearing a textured finish. There are no creaks or groans while handling the lens, and the zoom ring has enough friction. Turning the focus selector to MF allows the user to manually turn the focus ring. This also has enough friction in it to provide an accurate focus. On the other side of the barrel is a small switch which locks the zoom at 28mm to prevent lens creep.
The included lens cap is of the center-pinch design which I like much better than the Canon offerings. It's a lot easier to remove the cap with the included lens hood attached. Speaking of hoods, the included one is rather flimsy, and probably the worst part of the package. There is no interior surface flocking, and the surface of the plastic is a mix between matte and shiny. Attaching the hood is in typical bayonet fashion and locks in place.
The base of the lens has no aperture ring as I mentioned earlier, so the use of this lens would only be suitable for EOS cameras that can control aperture via the camera's body. The mounting ring is made of metal which is nice considering the cheap price. Generally, the lens is put together quite well, and my assumptions where starting to turn positive. However, the most important aspect is image quality and without further ado, I'll move on towards my observations with this lens and the Canon 5D.
Image Quality and Performance:
All of my tests were performed using a tripod, and having the camera set to ISO 100, RAW, and mirror lockup.
*F2.8: Center of the image was sharp with minor softness at the edges.
I only tested to F8 as these where the most commonly used f/stops that I used in my particular style of photography. However, the results were very pleasing, with only minor corner and edge softness at f2.8. The lenses sweet spot begins at F4 which is also a very useable aperture. Color rendition and contrast where also surprisingly good, and while I didn't have a Canon 24-70L next to me to compare with, I did have a few photos taken with that lens that I used to get an "eyeball" impression. Contrast and color where very similar, with no lens being worse than the other. Autofocus performance of the lens was also pretty good, although nowhere near as fast as Canon's USM offerings. The focus ring does turn when the camera is focusing though, and does take a bit of getting used too. Sometimes my finger rubs up against the focus ring while it's turning, which can be a distraction. Motor noise since it's not USM is also louder than Canon's offerings, but nothing that I would consider a detriment.
benjikan's Full Review: Tamron A09 for Pentax
As a professional Fashion/Beauty and Advertising photographer of over twenty years, my demands for optical excellence are quite stringent. I recently used this lens for a fashion editorial shoot and can say that this lens is wonderful. Fast and accurate auto focus and brutally sharp at 3.2 and above. Very good at 2.8. I use this lens on a Canon 20D BG-E2 Grip and it marries very well with it. I shot some beauty close up images and was amazed by the detail that this little lens resolved. The eye lashes bounced off of the page. I was also very pleased with the color rendition. The contrast of this lens is perhaps the best of all of the lenses I own and have owned in the past. Control of flare is superb. There is very little vignetting especially on the 20D which has a 1.6 ratio. The "Bokeh" on the Tamron is beautifully rendered especially wide open. Be sure to purchase a UV filter for this lens to protect the front element and to avoid color shifting in some clothing dyes. I especially appreciate the close focus capabilities of this lens. Not quite a macro, but very close. I was initially concerned by the fact that this lens is polycarbonate in construction which attributes to its' light weight. After reading several reports regarding the manner in which Tamron utilizes this material, I am confident that they made a good compromise. Tamron has been able to decrease the price of this lens by setting up there manufacturing plant in China. R&D is still done in Japan. The components of this lens are also manufactured in Japan
I also own the Tamron XR Di Macro 90 2.8 lens and must say that these two lenses are the best of the Tamron arsenal.
Final point. Would I recommend this lens to a working professional? Yes, Yes, Yes unequivocally!
