I recently got the minolta beercan lens for my A390. I notice that this lens is a constant F4, yet with my camera I can change to different F-stops as needed. I read through some post on this forum and one poster asked how should I use this lens? The answer seem to be use as you would any other lens. Also most people said the lens was sharper at 2 Fstops than fully open. My question is since the lens is a constant F4 how does that work say when I use F5.6 or F10 or any other Fstop at that matter? Just trying to wrap my head around this.
thanks!
