Hi Stefan,

I don't know if it helps but here are three recent shots with the 28/2.
In that session it did wear the 24/2.8 hood and a Hoya-cir-polariser.
Outdoor weather: Cloudy and moody..
Subects: Friendly yet temperamental..
Shots: All the above..

The shots are just scanned and 'auto-leveled'.

As you see, with this combination and in certain circumstances the tendency
to vignetting is quite obvious (see test 1). Yet not always (see test 3).
I'm kind of speculating at the moment about those influencing circumstances
:)

C.S.
