Superzoom P&S's may have long "effective" focal lengths, but....

On top of that, the images are washed out, and off-colour, plus they show considerable chromatic aberration and lack of contrast. All of which reduces detail. http://forums.dpreview.com/forums/re...ssage=35767510 Here's a shot of a bird's head with an APS sensor camera and a 350mm mirror lens. About a 500mm "equivalent." http://www.pbase.com/andersonrm/image/99552245/original And here's where a 20x superzoom lens' resolution and CA performance EASILY beats an easy to design and build 3X DSLR lens. http://www.cameralabs.com/reviews/Ca..._results.shtml Your point? Oh that's right. You NEVER have one. |

Your point? Oh that's right. You NEVER have one. November 2008 Yes, that original Canon 18-55mm was dog. Not equaled in crumminess until the Sony 18-70mm showed up. But they are hardly representative of good quality kit lenses. But you forgot to compare the resolution of that fixed-focal-length one-aperture-setting-only mirror lens with all focal-lengths from 35 to 420mm and apertures from f/2.8 to f/11 in the superzoom camera. How many mirror lenses would you have to haul around for that much focal-length reach and aperture range in all of them? How much would they cost? How large and sturdy of a camera bag to try to haul it all? Is that the largest aperture you can get at 500mm? F/5.6 isn't even enough aperture to allow shutter speeds fast enough freeze the image of someone walking during sunset let alone any other more demanding wildlife photography. Oh, and if you notice, the gull's image is downsized. The moon images were shot at 1/250 second, the gull at 1/3200 second. Even with all the technique advantages given to the mirror lens' image there's more pixel level details in the cropped-only 1:1 superzoom's moon images than in the gull image, even in its downsized version, where pixel-level details should have markedly increased, not reduced. Didn't you notice that? Could you find any two more totally disparate lens and shooting conditions to compare to try to prove something and yet totally fail even more at doing so? I don't think it possible. At least you got one of your fellow pretend-photographer trolls to out himself again by agreeing with you. He never even realized he was agreeing to your having provided perfect proof that you are 100% wrong and a fool. All that you managed to accomplish is make complete fools of both of you. |
