Continuing from Part 1 of our review of the PEN E-PL2, an in depth comparison was made between Olympus's new zoom lens, the M. Zuiko Digital ED 14-42mm f/3.5-5.6 II MSC (E-PL2) and the M. Zuiko Digital ED 14-42mm f/3.5-5.6 (E-PL1).
According to Olympus, the M. Zuiko Digital ED 14-42mm f/3.5-5.6 II MSC is an improvement from its predecessor, with careful mechanisms and features added to make it an overall better performer.
Notable features of the M. Zuiko Digital ED 14-42mm f/3.5-5.6 II MSC include:
- Incorporates Movie and Still Compatible (MSC) mechanism that increases auto-focusing speed and reduces operation noise
- Significantly smaller and lighter than its predecessor at only 112grams, with dimensions of 56.5 x 50mm
- ED glass: Reduces chromatic aberration during image capture
- f/3.5 (14mm) - f/5.6 (42mm)
- Lens lockable when not in use
How does the lens perform when put to test sharpness and distortion? Red Dot Photo finds out.
1. Distortion
To test for barrel and pincushion distortion, photographs of a window were taken with both lenses at their shortest (14mm) and longest (42mm) focal lengths.

Both lenses exhibited minimal distortion at both ends of their zoom range. Pincushion distortion is well controlled in both lenses. It is particularly impressive that even though the M. Zuiko Digital ED 14-42mm f/3.5-5.6 II MSC (E-PL2) is smaller than the E-PL1's kit lens, the resulting distortion between both sets of captured images were not significantly different.
2. Sharpness
To test centre to edge sharpness, a simple set up of Olympus's camera boxes were positioned and photographs at apertures 3.5, 4, 8 and 16 were taken.
The 100% centre crops show that images taken with the 14-42mm I at f/8 and f/16 were marginally softer, when compared to images taken with the 14-42mm II MSC at the same apertures.

Both lenses appear to be sharpest at wide apertures of f/3.5 and f/4.0, leading to the conclusion that both lenses would be excellent for low light photography.
The 100% bottom left edge crops show that images taken with the 14-42mm II MSC at large apertures (f/3.5 and f/4.0) were comparatively softer than images captured with the 14-42mm I at the same apertures.
However, the 14-42mm II MSC is sharper than the E-PL1's lens at f/16.

3. Conclusion
The 14-42mm II MSC is definitely a worthy investment for novice photographers desiring to learn more about photography.
Its consistency in sharpness both at the centre and corners surpasses the 14-42mm I and has managed to control the barrel distortion to a better degree than the 14-42mm I. Coupled with the fact that the 14-42mm II MSC comes in a more compact package, it overall offers a marked improvement over the 14-42mm I.
Olympus has done a good job in upgrading its kit lens and achieved a more compact size whilst maintaining (if not surpassing) its signature quality.
