Caro Betto

Ti ringrazio per l'apprezzemente gentile, particolarmente riguarde l'apertura, e molto interessando.

Ho letto prima su TE che un'apertura piu picolo di f/11 non e un buon idea perche dopo f/12 le lente vanno "morbido". Cosa e la tua esperienza con questa problema?

Un caro saluto
Lisa

Yes Lisa,
as far as I know each lens has its own best aperture point. In the case of your lens, I believe, the best results seem to be at wide apertures and the minimum should be not less than f/16. In your case you should open the lens but it is always a tradeoff, where if you are looking for a very high DOF or a very long time, you will be obliged to close the lens paying the sharpness....
Benedetto
