If there are enough of us we can force lens makers to make sharper lenses. If not, they will continue to make 'defective', (i.e., soft) lenses. You want all sharp lenses? No problem, but forget contrast, bokeh etc. and add CA, CL and the myriad of other lens problems one can get. Then you won't be happy, you'll have defective (i.e. won't deliver a pleasing or even usable image) lenses, but you'll have sharp lenses. That's why I don't subscribe to such an aim. As for cults, that's something for vulnerable sheep and ego-tripping, often abusive leaders --- maybe just right for you, but not for most people. F'up, -Wolfgang What difference does buying the sharpest lenses make if you are going to put them on a camera where the mirror slap and shutter slap shake the camera so much that you can never make use of their full resolving power. On reconsideration, I take that back. There is only one situation in which you can use any D/SLR lens' full resolving power. If you mount the camera on a sturdy tripod in a pitch-black room, lock up the mirror, use a slow shutter-speed (about 30 seconds to wait for all vibrations to dampen down), triggered on hand-free time-delay or with a cable-release. Fire a flash mounted off-camera because the firing of the strobe imparts its own pulse of motion, detectable by anyone who has held a firing flash. Trigger the flash pulse 30 seconds after the first curtain opens, while both curtains of the shutter are still open, to create the exposure. Using a 2nd curtain flash-sync setting if you have one. Only then can you detect or use a lens' true resolving power with your D/SLR camera. A unique shooting situation but the only one way where you can accomplish this task. (Wondering when they're ever going to get smart enough to figure this stuff out.) |

Showing that you've never even read the tests done on this problem, nor tested it yourself. What's the matter? You don't own any camera to test? Fire a flash mounted off-camera because the firing of the strobe imparts its own pulse of motion, detectable by anyone who has held a firing flash. Oh, yes, the photons provide *sooo* much pulse of motion! No, you pathetic "can't dazzle them with brilliance so baffle them with your bull****" moron. It's caused by the discharge in the capacitor and its dielectric layers responding to the release of energy. **** are you ever stupid. PROVED AGAIN! ANYONE with a flash unit can fire it off with the test button on it and feel the jolt occurring from the capacitor discharging. Oh wait, that's right. You have probably never even touched a flash unit, nor any camera. You just proved that by refuting that flash units don't impart a pulse of motion when fired. Once you combine a couple million flashes, you could slightly move a very thin piece of paper with a synchronized mass flash ... as it burns to ashes from the intense light.
