Testurteil: "3.5 out of 5"
Test: Einzeltest: Pentax DA 40mm f/2.8 XS Pancake Lens
Zitat: Pros: + Excellent sharpness from maximum aperture
+ Thin and lightweight
+ Good build quality
+ Vignetting is well-controlled
Cons: - High CA levels towards edges of the frame when stopped down
- Loss of contrast and flare when shooting into the light
- Rubber lens cap falls off easily
Obvious benefits of a pancake lens like this are the compact size and lightweight, but this lens delivers excellent sharpness too.
The issues with flare and high CA levels when stopped down may be off-putting to some, but if care is taken to use this lens within its limits, it can deliver excellent quality images, without the bulk of a normal Pentax K-mount lens.
This basic, but compact lens could be the ideal lens for Pentax shooters wishing to travel as light as possible.
