What is better Optical or Digital?

Rosann Mccomb: OPTICAL is the only zoom to pay attention to??Get a Samsung s630 Great Price Excellent Camera

Arden Strachn: I'm no expert but I think optical zoom is better because is "real" zoom. Digital zoom is like computed or extrapolated zoom, perhaps cheap or cheat zoom, lol.

Arnulfo Seegars: Another vote for Optical here. Optical is the only true zoom, changing the camera's viewpoint to match your needs. Digital simply takes the existing image and stretches it or takes a section of it.Digital zoom is like taking a "one-size-fits-all" teeshirt and tucking it in or stretching it for three different people.Optical zoom is like getting three different size shirts....Show more

Azzie Trembly: Like all the other posters said, optical is the King. But your asking the wrong croud bout the cams. Go to the camcorder section not here. There is the crowd you SHOULD ask. Good luck:)

Robt Betker: digital zoom is a con, all previous answerers have said it! sort of - except mandrey he has been fooled by the demon marketersyou can do a "digital zoom" in the computer - as above its just a crop of the full image, anyone can do that in the computer, your best to have the full file to start with, then do a "digital zoom" in the computer and pick a number like 10x or somethingoptical is real, digital is marketing foolery with the consumer - just pay attention to the optical numbera...Show more

Cyndy Grimes: Im trying to decided between these two Cameras but i dont know which one is the better buy:Cam1:http://www.target.com/dp/B000J5SP26/qid=1192511183...orCam2: http://www.target.com/dp/B000UO796Y/ref=in_pe_rece......Show more

Elden Dedon: I can't help you choose between those two cameras as I am not familiar with them, but...Optical zoom is good and digital zoom sucks. Optical zoom is "real" zoom done with the camera lens. Digital zoom is really just a way to enlarge pixels and degrade the image. Ignore it completely! when you are comparing cameras.See: http://www.flickr.com/pho! tos/samfeinstein/10986660... for one example. The difference is clear. Take note of the digital noise in the so-called digital zoomed image. This is typical. The optical zoomed image is not great, but this is taken with the same point and shoot camera as the other example.Here are three sample pictures taken with my Canon Powershot SD900, which is a 10.0 megapixel camera. All three pictures are taken with the optical zoom maxed out at 3X or 23.1 mm, which is the equivalent of 111.6 mm after calculating for the lens crop factor. There is no image processing at all done with any of these pictures. All were taken using the self-timer to (hopefully) eliminate camera shake as the camera sat on the top of my car. (Okay, I'll use a tripod next time, but I think they are pretty sharp images.) Please click on "View All Sizes" and then view each image at the largest size available, which should be 3648 x 2736 pixels. The first picture (3xOpticalFull) is the full frame image! at 3x optical zoom, or 111 mm. The second picture (4xDigitalFull) is the result of zooming out the additional 4x in digital zoom, for an equivalent of 444 mm. The third picture (3xOpticalCrop) is actually a cropped version of the original image, maintaining the full pixel dimension. In other words, I accomplished the "digital zoom" entirely in the computer and not in the camera. If you compare the full-sized images, I think it is immediately obvious that the third picture is far superior in any aspect that you care to examine. I think it is much sharper (Check the tower and the antenna up near the top of the frame.), has better color, and less digital noise and artifact (Check the plain sky and the shadows on the building.). These images are all tagged "digital zoom."3xOpticalFull: http://www.flickr.com/photos/7189769@N04/459603923...4xDigitalFull: http://www.flickr.com/photos/7189769@N04/459603931...3xOpticalCrop: http://www.flickr.com/photos/7189769@N04/459603939..! .In other words, please ignore any claims of superiority based on "digi! tal zoom" when you choose your camera. It is only "in camera cropping" and it is not anywhere near as good as "in computer cropping." Any attempts at cropping a digitally-zoomed picture will be a waste of time.See also, about half-way down this page: http://photo.net/equipment/digital/basics/...Show more
