what fstop gives max sharpness

[Ed Kishel]

did a search and found some close answers and I know this is spoken of in the DVX book, but am I correct that the DVX's lens is sharpest at between f4 and f8?

I heard 5.6 was optimal...

thanks, -Ed

I think the rule with most lenses is they are sharpest between 2-3 stops from the minimum aperture and 2 stops from the maximum aperture.

Anywhere between 2.8 and 13 seems good to me.

a lens' sweet spot is usually between 5.6 and 8. DVX lens seems to perform at its sharpest around these fstops.

I remember Barry saying that after extensive testing, he found F4.0 to be optimal. At least that's what I use every time I don't care about shallow depth of field.

between 4 and 5.6, thats what I thought. Is this "middleground" common to most lenses, or just the DVX?

how much does it drop off at F 1.6?
cause i have been having issues with sharpness lately, because of a lack of light ive been shooting wide open most of the time on this last project.

I have no idea about whats the best Tstop for the Dvx100 , but in the 35mm world , with Primo , zeiss , cook and others , the sharpest range is from 5.6 to 11

And actually it is rather rare that we shoot at theses apertures , 2.8 - 4 is the norm... we gota keep that dof down...

I hear wide open reduces sharpness but I dont know by how much.

 

[Michael Summers]

a lot.

That sounds right to me, because there was that huge uproar over the HVX's 720 res chart test being at like 4.4 or something, so 5.6 sounds right.
