Olympus Zuiko Digital - lens - 25 mm F/2.8

Sigma EX macro lens - 105 mm F/2.8

Advantages: value for money (compared to pro level), build quality,
Disadvantages: makes you think your a pro, but by its nature, proves you otherwise.

quality macro lens. It's a bit slow on auto focus, but if you shooting macro the chances are that the subject is pretty still. I use mine most days. Tech Spec: Focal length - 105mm Weight - about 500g Magnification - 1:1 f-stop range - 2.8-32 Filter size 58mm Mounts: SIGMA, CANON, NIKON, SONY, PENTAX Final point: Read about macro photography before buying a lens like this. The technique is NOT the same as 'point and shoot'. ...

Review of Sigma EX macro lens - 105 mm F/2.8

The nikon 70-200mm F2.8 VR, top-of-the-line

Advantages: Beautiful bokeh, tack-sharp, vibration reduction, easy to use, many useful accessories
Disadvantages: heavy, expensive, slight vignetting, prone to flaring

their version, the so-called "vibration reduction", was the 80-400mm f/4.5-5.6 ED. An interesting lens to be sure, but Nikon owners really started to get excited at the announcement of the AF-S 70-200 F2.8 VR. This lens, a successor of a highly regarded line of professional lenses, turned out to be spectacular: the image stabila? sorry, the vibration reduction was possibly even more effective than Canon's and the image quality? Well, I am going to discuss that right now! ---Image quality--- The 70-200 VR is a tack-sharp lens, as you would expect of a lens in this price class. It is not even in the same ballpark as normal consumer lenses: the colours are vibrant, the details sharp, and the bokeh (the appearance of parts of the picture that our out of focus) is stunning. The lens is particularly famous for the silky smooth rendering of out ...

Review of Nikon Zoom-Nikkor telephoto zoom lens - 70 mm - 200 mm F/2.8

Sigma EX DG 70-200mm f2.8 HSM Macro

Advantages: Build quality. Finish. Range. Fast maximum aperture.
Disadvantages: Image quality not as good as expected. Chromatic Aberration.

removed whenever you choose to use the lens hand-held. Being an EX DG lens, it is suitable for use on either FF (Full-Frame) or APS-C cropped sensor cameras when it effectively behaves like a 105-300mm f/2.8 (on Nikon APS-C), 112-320mm f/2.8 (on Canon APS-C) or 119-340mm f/2.8 on Sigma DSLR cameras. These make interesting options on the APS-C size sensor cameras and it can be assumed the camera has a completely different set of values when used with such cameras to those when used on full-frame. Interesting? The fast f/2.8 maximum aperture provides great fun for shallow DOF (depth-of-field) shots where particularly at the 200mm end of the zoom, depth-of-field is excitingly shallow. Whilst the lens is referred to as 'macro' within it's descriptive title, the term is used somewhat loosely. True macro lenses provide genuine 1 to 1 life ...
