why i use F13 le pic still not sharp de? with tripod,mirror lockup,timer and IS off??:think:
Otherwise you can shoot at F22 to get even sharper images.
Depending on lens, F13 doesn't mean your images will be sharp...it is just the depth of field has increased. Otherwise you can shoot at F22 to get even sharper images.
Usually I would avoid going beyond F11 as diffraction would kick in and affecting IQ. Anyway we would need a picture from you before more conclusions can be made.
One more possibility: where is your focus point of the subject?
HAR??????!!!
Diffraction is also called "small aperture diffraction". If happens when the aperture is too small. Usually any aperture smaller than F16 (bigger F number) on a APS-C sensor camera, diffraction starts to set in and you start losing sharpness...
Please. If you don't know the subject matter, or not sure, best to keep your mouth shut. It is ok to not know stuff...
PLEASE provide EXIX details and a sample PHOTOGRAPH if you would like members to assist.
Read his whole post again...?
he meant that DOF increases along with the aperture number and not the sharpness, if not we'll all shoot at f22 to get the maximum sharpness.
I hope you get what he originally meant and what i mean :sweat:

still no sign of TS... i'm wondering why TS specifically chose F13?
But still diffraction do not kick in beyond F11 for most DSLRs. For APS-C diffraction mostly kicks in with apertures smaller than F16. For FF, you can stop down even more before diffraction kicks in. For small sensor prosumer PnS cameras, diffraction can kick in with apertures as small as F11.
