DLA is Nonsense! It should be deleted from the reviews.

I think what DLA needs is a little more understanding and kindness, not agression and hate.

I do not see it, aggression and hate that is.

Well, if someone said you were nonsense and suggested *you* be deleted, wouldn't you feel someone was acting agressively toward you? Might you even feel that someone hated you? Poor, misunderstood DLA. What did it ever do to deserve this kind of treatment?


(I might add that I was, and still am, being a little silly. I don't actually think the OP was being hateful.)


Though, on a (slightly) more serious note, I personally find DLA useful and would not like to see it purged, deleted, stricken from reviews, or otherwise persecuted, oppressed, or marginalized. Sure, opening up wider than the DLA doesn't mean diffraction is impossible to detect. Does that mean it is nonsense? if I stop down way past the DLA, I figure diffraction will have an effect on sharpness. When I do astrophotography, I feel there is little point using a barlow if the f/ number of my scope is greater than the DLA of my ccd.


It's a rule of thumb. Do what you will with it (even if that's nothing).
