Tamron 28-75mm f/2.8 Review - The Sharpest Zoom Lens For Cropped Sensor DSLR

!9#: Tamron 28-75mm f/2.8 Review - The Sharpest Zoom Lens For Cropped Sensor DSLR

If you own a cropped sensor DSLR and are in the market for a great zoom lens, then the Tamron 28-75mm f/2.8 is an excellent buy. I tested this lens on both the cropped sensor and full frame sensor cameras. I used the Nikon mount, though Tamron made the Sony, Pentax, and Canon mounts as well.

Originally designed for a full frame sensor camera, the focal length is not very comfortable on an APS-C (cropped) sensor DSLR. However, the image quality is much better in the cropped censor camera than the full frame equivalent.

If you use an APS-C DSLR and require a wider angle and more versatile focal length, you are better off buying the Tamron 17-50mm f/2.8 VC lens.

With the Tamron 28-75mm f/2.8, I was able to get extremely sharp images, perhaps the best among all Tamron zoom lenses, when used in conjunction with an APS-C camera. Distortion, chromatic aberration, and vignetting are all minimal to negligible. If you feel that you can adjust to the awkward zoom range, you'll get yourself a great zoom lens for your cropped sensor camera.

I was able to take some really sharp group photos and shoot some interesting still life with this lens.

For those using full frame DSLRs, the lens does not perform as well compared when used in conjunction with a cropped sensor camera. All the distortion, vignetting and chromatic aberration will start to show up in the corner. This of course can be remedied by using the proper post processing techniques.

In conclusion, the Tamron 28-75mm f/2.8 is an excellent professional lens at a bargain price.

The other thing I found is, besides with its waterproof condition, Kodak announces this new model will be shockproof and dustproof too. I guess they decided to upgrade its durability to make it more resistant with any extreme conditions.

2 Use the gaping openings faster f/2.8 shutter speed and great bokeh (bokeh is the blurred background, the theme is to ask yourPicture editor and professional looking images.)
3 Take superb portraits, because the focal length this lens is ideal for portraits. On a Canon Rebel, is the focal length of 96 mm with the 1.6 crop factor.
4 Save money by buying this instead of the 100mm macro lens. The picture quality is excellent, so you will not regret the purchase ("buyer's remorse 'no)
5 excellent optics for video on your Canon Rebel, 50D, and 7D. Sharper lensesproduce superior video quality and sharpness of this lens is undeniable. Even higher performance at lower light during treatment with the video because of the large opening.
6 Made specifically for APS-C sensor image. If you have a rebel, a 20D, 60D and 7D, this goal is for you! Canon EF-S produces lenses as the Canon 60 mm handle with this particular type of camera sensor. The technology is ideal for the best score of the entry-mid level digital SLRCameras.

There are a few things on the down side:

Equipped with Canon's Optical Image Stabilizer (IS) technology, the Canon EF-S 18-55mm standard zoom lens is ideal for just about any application. IS technology compensates for camera shake by providing the equivalent effect of a shutter speed up to four stops faster. This allows you to take sharp handheld shots even in low-light conditions--a must for sports and nature photography. The lens also offers an aspherical lens element that corrects for aberration, thus producing a topnotch image throughout the zoom range, and a circular aperture that exquisitely renders out-of-focus backgrounds. Despite its minimal size, weight, and cost, the lens expands the picture-taking possibilities any time slow shutter speeds are needed.

• Focal Length & Maximum Aperture - 18-55mm f/3.5-5.6
• Lens Construction - 16 elements in 12 groups, including UD-glass and aspherical lenses
• Diagonal Angle of View - 74 20' - 7 50' (with APS-C image sensors)
• Focus Adjustment - Gear-driven
• Closest Focusing Distance - 1.48 ft./0.45m (maximum close-up magnification 0.24x)
