The cold, hard reality of 45mp and no in-body stabilization

But only when the shake disallows the higher 45MP grain. -hh In reality you would need some 40MP sensor to measure up to a film like Kodak T-Max 400 hundred ... Sounds about right based on the general rule of thumb of needing to sample at twice the target (times two dimensions in this case). ... but you could easily adapt the "x mm1/x s" rule to 1/2x or whatever you think is necessary for your skills. Agreed, that's really all that this ultimately comes down to. If you're going on a safari planing on sitting on the roof of a tourist buss in the Serengeti at noon then you could probably make do without IS or legs but waiting in a hide in Lappland at dusk ain't the same thing... Even the Sunny 16 situation will depend on just how far one is pushing things. For example, this image's quality is breaking down: http://www.huntzinger.com/gallery/index.php/SAN/rueppells_parrot-7Y8A1520_66 ....but that's hardly a surprise in context, as it was an extreme crop that was left to work with only ~7% of the original frame's sensor data. -hh |
