Sigma 50-200mm F4-5.6 DC OS HSM Review

User Experience3 months

Used on aNikon D3100

This Is a 3rd Party Lens for Canon, Nikon, Sony or Pentax users & it does cost much less than the Manufactures original lens.

From My experiences This lens is great for out door portraits & its quit easy to handle with the “Internal Focusing” system even at the tele end with infinity focus its just 13cm long (with out the l
ens cap). And it comes with a Optical Stabilizer system to prevent camera shake & this does make a difference some times.

This lens has a Metal Mount which Nikkor 55-200mm lacks & when it comes to Fast focusing its quick but takes around 1sec to go from minimum focus to Infinity.Manual Focus is tricky because its little hard to turn the Focus ring.

When It comes to built quality only advantage is the Metal Mount but through out the lens the built quality is better than average for a lens of its class but i prefer my old Tamron Lens over this.

It has a 55mm Filter size & great lens hood (included with the lens).

Between5.6f-8f & over 85mm This lens performs at its best but after 11f the images a soften & the sharpness is dropped around 50mm-100mm.But as i have heard, this lens has a better CA ratio than the Nikkor 55-200mm but i never had a chance to test it out.

This Lens is definitely not for Macro course it only has a 0.22x magnification & the minimum focus distance is more than 3ft.

This lens is ideal for a beginner who’s using a D3100 or D5100 or a 1100D after they are finished testing the kit lens. But I would recommend to Collect some more money & go for a Nikkor 55-300mm VR or a 70-300mm Tamron tele/macro lens because of the longer reach .but for a portrait lens, this one will exceed your expectations.

This is a sample picture of a flower taken at minimum focus distance at 5.6f with 1/200 shutter speed & 200mm.As you can see how the back ground is blurd is brilliant.And the next image is with same settings but at 5omm
