Yourlensreview - Lens - Sigma 18-50 F/2.8 EX DC

- This is a sharp lens, especially from F4.0
- Well build
- Price compared to Nikon variants.

- CA when using wide open, even at F8.0 the problem is still visible in some situations
- Slow AF, body driven on Nikon. When does Sigma add HSM to these lenses?
- Lens cap is almost impossible to remove when the hood is on the lens. So I bought a Nikon lens cap.

This is a nice replacement for the Nikon kitlens, when you want a faster lens. Too bad it suffers from some CA and the AF is not really modern. Sigma where's the HSM motor?

- F2.8 on all range
- This lens is sharp, especially from F4.0
- Hood included
- Price
- Build quality

- Warm tuning and contrast (some floot of yellow), however can also be a pro for someone.
- Lens hunt in low light situations.
- Some distorage at 18mm. From > 22 mm no distorage visible anymore.

My allaround lens. Very sharp, sharper as my Canon 10-22 mm. However, not as fast as the Canon and sometimes some CA noticeable, however this is at a minimum.
