Tamron 28-300mm Vc - exquisite Super Zoom Lens For Full Frame Dslr

Digital Photography Secretsby David Peterson Click Here! How to

Today I tried the Tamron 28-300mm Vc Lens on my Nikon D300s Camera. The Vc update is only ready for Canon and Nikon users. The Vibration payment (Vc) highlight is well worth the money I paid for it.

This record will be a short retell on this Lens.

Zoom Lens

I found the visual potential of this lens to be great so I tested it with both full frame (Nikon D700) and cropped sensor Cameras (Nikon D300s). To my surprise, the images came out very sharp on both cameras. To a general viewer, the image potential of the lens is comparable to a professional lens. The super zoom range was just exquisite on my full frame camera.

However, I found the zoom length to be a bit awkward for a cropped sensor camera. If you want a best range, look at the Tamron 18-270mm Vc lens instead. This lens will give you a best zoom range for a cropped sensor DSlr. Although the 18-270mm Vc has a best range, I've found the lens' visual potential to be less sharp than the Tamron 28-300mm Vc.

When doing the review, I'm mildly surprised that this lens has a fast and spoton autofocus mechanism. Here's one tip on autofocus: In low light, switch to hand-operated focus. This will prevent autofocus hunting (due to the lens' small aperture).

In terms of sharpness, I found the town and border sharpness to be excellent. The distortion is also minimal.

Another very handy highlight is the zoom lock mechanism. I'm not afraid of zoom creep, especially when transporting the lens. The lens is also very light weight, production it very easy to handle.

As a final opinion for this review, I rate this lens as a great value proposition, ideal for non-professional use and travel.

I don't advise this for professional use because the slow aperture speed makes it impractical for use in most professional Photography situations. Nor does it make sense to use this lens in ultimate weather.

Crisp and sharp photos are the consequent of the previously mentioned vibration control law but with all lenses, the features don't correlate to the potential Nikon Ed glass inside the lens.
