Tamron 18-270mm f/3.5-6.3

Photozone has reviewed the ultrazoom lens Tamron 18-270mm f/3.5-6.3 Di II VC LD Aspherical IF Macro. The lens got an impressive 15x zoom and optical image stabilization, but it remains to be seen if it is able to produce good pictures. Photozone tested the Tamron lens on a Canon EOS (APS-C) camera (Canon EOS 50D to precise).

Photozone ends up giving the Tamron lens a rather avergae rating as the lens is not able to produce the best pictures on this planet, but what can you expect when you have such a long zoom range. The build quality is ok, you get some chromatic aberrations and there is not that much vignetting, but on a high resolution camera such as the Canon EOS 50D DSLR (15 megapixels) you get some problems with the image quality.
Overall the Tamron 18-270mm f/3.5-6.3 Di II VC LD Aspherical IF Macro lens seems like a very convenient lens, but it does not produce pictures of highest quality.

Sigma 70-300mm f/4-5.6

SLR Gear has reviewed the standard superzoom lens from Sigma, the Sigma 70-300mm f/4-5.6 DG APO Macro lens. The 70-300mm seem to be a zoom range that almost all lens manufacturers produce and it is very handy range for wildlife photographers.

SLR Gear ends up giving the Sigma lens an ok rating due to the fact that the lens is able to produce good picture if you stop it down to f8 and smaller apertures. At bigger apertures the lens has a bit of corner softness. The Sigma 70-300mm f/4-5.6 DG APO Macro lens seems like a cheap alternative to other brands if you are on a budget.
