What is 20x zoom equivalent

So the other hidden part of your question then, is, what gives you as much reach not as much zoom as a superzoom camera?

For the sake of argument, I have chosen the Canon SX20IS, as it is a current-model "superzoom" camera that has a 20x zoom range. The real, phsycial focal length of the lens is mm. Its "focal length equivalent" is from mm which is where the 20x number comes from, and also approximates what the focal length of lenses would have to be on a 35mm film camera or full-frame dSLR. The bundled mm kit lens takes care of the 14mm on the wide angle. Then you need to get something out to mm on the telephoto side.

That will cover you out to mm and beyond, which gives you an "equivalent focal lenth" of mm , which will give you slightly more "reach" than the Canon SX20IS, with likely vastly superior image quality. Also, though, you'll be missing the focal length between mm. That entire package, of course, will also cost you many times more.

So the conclusion is probably most likely to get the "20x" idea out of your head, because especially if he's never had a 20x zoom camera the idea is truly artificial. Is it worth the hefty price tag? We take a look at the Cine, the high-end model in this series. The Nikon Z9 is the company's first camera to feature a stacked CMOS sensor, which brings a raft of new features, including blazing speed and autofocus performance to the Z lineup.

Nik Silver Efex Pro 3, one of the standout components of Nik Collection 4, is a black-and-white conversion tool that goes far further than the grayscale or black-and-white tools built into all-in-one photo apps.

These capable cameras should be solid and well-built, have both speed and focus for capturing fast action and offer professional-level image quality.

HippiesJimmy am, 7 November I'm very impressed with what I saw with the sony compact digital camera that has 20x zoom I want to know which canon lens is that equates to? Publish Preview.

Here's a quick test of it's range that I did a couple weeks ago.

SLR lenses are not generally designed that way because of the huge compromise in image quality, but also the weight of building something like that for SLR use. Post Reply Preview.

The 20x simply means the longest length is 20x the shortest - so it might be equivalent to mm, mm, mm or anything in between.

Remember that when manufacturers talk about "Equivalent to xxxmm" they are referring to equivalence to 35mm ie full frame DSLR Field of View FoV , so you'll need to take into account the crop of your DSLR if you're seeking somthing of similar reach. Edited by acoustic snails member 9 years ago. Super zoom bridge cameras are all fine and dandy I have owned a few in my time but to have so many elements in a lens will cause a degradation in IQ. TBH it is also quite unnecessary to have such long theoretical focal lengths on a camera.

I used to own a fuji HS20 that had a equivalent focal length of something like 24mmmm ish. I very rarely got anywhere near full stretch because the vast majority of us have no need for a lens above mm really apart from keen birders or wildlife photogs. Dave Wilson Cumbria 9 years ago. Here's the answer - "it's all to do with marketing". After all, most people would buy a 20x zoom camera over one that had a paltry 15x zoom because 'it's better' HippiesJimmy 9 years ago.

Those pics look sharp! The 50mm comes from the diagonal of a full frame size 35mm film. The actual measure is 24mm by 36mm with a diagonal of The diagonal is such an odd number; it is customary to round up to 50mm.

Thomas Edison invented motion pictures to be shown in a penny arcade. Edison and his chief engineer bargained with George Eastman for film. Kodak was making a 70mm wide roll film. The three decided upon 70mm slit down the middle thus was born 35mm. The year was Between the sprockets, the space allotted to the image was 24mm. The height of the image was fixed at 18mm thus the image on the film was 24mm by 18mm. This projected a rectangular image that lingered till wide-screen came about.

In the Leica 35mm camera came to market. Barnack, chief engineer, designed the camera with the film travel horizontal. He doubled the 18mm height to 36mm, this became the width of the 35mm framer. The camera was fitted with a 50mm fixed lens. What is normal and what is wide-angle and what is telephoto is dependent on the image size of the film or digital sensor. Normal for an 8x10 inch view camera is 13 inches mm. Once the image is taken it must be viewed.
