Default Sigma 18-50mm f2.8-4.5 DC OS HSM

Sigma 18-50mm f2.8-4.5 DC OS HSM

These lenses appear available, on the market, MSRP of $500, are usually discounted... and have very, very few reviews. It's as though they are the "mystery lens". I don't know if that is because they are junk or they are great... but they are definity below the radar.

Does anyone have any insights????

Thanks !

SLRGear.com tested one and it appears to be a reasonably good stabilized standard zoom. It's new and so hard to find, but Adorama has them for $299.

if you have stablisation in the camera you would be better off with the the sigma 18-50mm f2.8 - constant aperture means its a whole stop faster at 50mm

then there is the tamron 17-50mm f2.8 better optics than the sigma but build quality well heard bits come loose etc though is apparenlty self maintainable

i chose the sigma and been happy with it - nice and sharp and built like a tank and the f2.8 aperture means it is not to bad for isolating your subjects aslong as they not right infront of other stuff too so thats a bonus

took this photo with it just last weekend

i did look at this lense and if i was shooting canon or nikon which only have lens based stablisation then would have been my choice but since i shoot pentax with in camera stabilsation then it didn't make much sence

Sigma dSLRs also rely on optical image stabilization in the lens.
