Is resolution ever preserved shooting hand-held compared to tripodmounting?

I suggested to Dpreview to test the new 50mp Canon hand-held and on a tripod to see if there is any resolution loss hand-held. They said they'd do it. They're going to use a production model because the ones they have now are pre-production. Pixel density on the Canon (and the m4/3rds gear) is high, each pixel measuring smaller than a red blood cell so any motion by the hand not compensated for could theoretically reduce resolution. Be interesting to see under what conditions resolution diminishes. In normal circumstances hand holding will reduce resolution. Even using the rule-of-thumb of shutter speed faster than FL is only valid for smallish prints. If one could attain really high shutter speeds (1/16000) then it would not affect registration as much, but noise would tend to be higher reducing the resolution benefit. All that said, hand held shots at 1/400 - 1/800 in good lighting tend to look really sharp (given adequate hand holding technique and a smooth release). Combining a high speed flash (high power TTL flash at low power output) with low ambient lighting and a high-ish shutter speed (1/250 or better if the camera will sync there) will also hide movement somewhat. But in the end, nothing beats a tripod with mirror lockup (or a non-reflex camera). |

Such figures aren't much use unless focal length is also considered. Stated earlier along with the clarification that the focal length rule of thumb really applies to smallish prints. I'd expect, in the whole, that that would be clear enough to most without having to re-qualify everything. |

But in the end, nothing beats a tripod with mirror lockup (or a non-reflex camera). Flashes are different. A controlled flash can fire at 1/50,000 second which will freeze anything, more or less. The issue isn't so much the flash but exposure due to ambient light blurring the overall image. |
