"New water and oil repellant SP (Super Protective) lens coating for easy cleaning" they say in the presentation of the lens. Which is a good thing for a wide-angle lens - But instead it seems to attrack dust, and with the build-in sun-shade I find it hard to remove with my lens cleaning cloth, so I'll need a rubber bulb blower brush for this lens.

In the sun

Generally the lens shows very little lensflare as long at it is dust free (see remarks above! )

In the first test picture there is some green flare-spots at F/3.5 and F/5.6.

The wierd rays/bleeding you see is a known artifact from the D70 ccd. It hasn't got enything to do wish the lens. In the test picture it was visible up to F/8.

At lower F-stops the sun is rather difuse. The higher F-stop the more it get the destinct star-look

This picture taken in landscape orientation with the sun a little more to the side shows two things.

1. Dust-spots give some flare. (The higher the F-stop the more sharp these spots get so at F/22 it looks more like dust than flare!)

2. In this position the sun is more difuse even at F/22.
