The Tamron AF 180mm f/3.5 SP Di LD [IF] macro offers a near-flawless performance. Optically it doesn’t leave anything to be desired – the resolution is very good to excellent from f/3.5 all the way down to f/16 and vignetting, CAs and distortions are non-issues in field conditions. The bokeh (out-of-focus blur), a primary aspect in macro photography, is very smooth and buttery. The build quality of the Tamron is very good but there is one bug – the lens has no focus limiter and the rather slow AF combined with AF hunting can be a frequent and rather tiresome experience. Thanks to a focus clutch mechanism you can switch between AF and MF as easy as pushing/pulling the focus ring so if necessary you should give the AF a better hint by manual pre-focusing. Other than that it is a really impressive lens. READ FULL REVIEW

Photo Zone

The Tamron AF 17-35mm f/2.8-4 Di LD Aspherical IF SP proved to be a very decent standard zoom lens within the tested APS-C DSLR scope. The resolution figures are excellent in the center of the image and good to very good at the borders. Distortions are very pronounced at 17mm but very moderate otherwise. Typical for full frame lenses vignetting is very well controlled. CAs are a little on the high side specifically at 24mm. The build quality is generally pretty good but the direct competition does a little better job in this respect. When shopping for a new lens the Tamron AF 17-50mm f/2.8 SP may be a tad better and more versatile in terms of focal length range but without full format capabilities. If you prefer to have a lens living in both camps the AF 17-35mm f/2.8-4 Di SP may be still worth a deeper look. READ FULL REVIEW

Tamron 500mm f/8 SP Review Round-Up

When used with care the Tamron 500mm f/8 SP mirror lens can be able to produce decent results but don’t expect this to be easy – most of my real life sample images were blurred (caused by shake). A (max.) aperture of f/8 is very slow for a 500mm lens (750mm equivalent on APS-C) to start with and effectively this is a f/11 (or to be precise: T/11) lens due to the light loss caused by the secondary mirror. For reasonably sharp results you either need a very sturdy tripod or extremely fast shutter speeds (1/750sec or faster). When used “hand-held” you will need to choose very high ISO settings even in bright light conditions which can’t be desirable in terms of image quality and a tripod would destroy the weight advantage of a mirror lens in field conditions. The rather poor bokeh may be a funny effect in the beginning but once the initial coolness is gone it is just odd and often disturbing. Unless you want to have a lens for “emergency” use you should probably better consider conventional tele lenses. “¦ READ FULL REVIEW
