Is 3x optical zoom and 5x digital zoom good? Confidence votes 3. 3x optical zoom and 5x digital zoom are standard features on most mid-range pocket digital cameras. A better optical zoom capability would be 6x or 8x optical.The digital zoom capability can be ignored, since all it does is crop and expand your image, necessarily reducing its resolution.onfidence votes 3. 3x optical zoom and 5x digital zoom are standard features on most mid-range pocket digital cameras.

Summary The Panasonic Lumix FZ72, or FZ70 as it's known in North America, is a super-zoom camera with a 16.1 Megapixel compact sensor and a whopping 60x stabilised optical zoom.he Lumix FZ70 / FZ72 retains the 3D Photo mode which takes a burst of images while you move the camera around 10cm sideways, before automatically selecting two photos from the group and using parallax information to generate a 3D image. It's a similar approach to that pioneered by Sony.

iPhone X review: The best damn product Apple has ever made iPhone 7 was already good at getting images no iPhone could before it. iPhone 8 could get those images with better detail, especially in the details and textures. iPhone X can make sure they're as clear and crisp as possible.

- Still, this doesn't mean that the UltraPixel camera is a bad one. Quite the opposite – it can take pretty pictures and videos despite having just 4MP to work with. And it might serve you even better if you're familiar with all its modes, settings, and peculiarities.Below we've compiled a list of 11 tips and tricks on taking better photos and videos with your HTC One (M8) .. The camera on the HTC One (M8) has a power-saving stand-by mode. You enable it by pressing the power key with the Camera app running. Then if you press the power key again, your lock screen and pattern will be bypassed (assuming you have these enabled) so that you can take the photo instantly.

Birding Binoculars Buying Guide | Recommendations for 2017 As far as bird watching is considered, a binocular with a magnification of 8x would work well. However if you are going to use your binoculars for varying purposes, then a 10x would be the best suited all-rounder. Most preferred magnification for Bird watching by birders is 8x.

Understand Camera Zoom Lenses In other words, the multiplier is the difference between the smallest and largest focal length measurements of the lens. For example, if a 10X optical zoom lens on a digital camera has a minimum focal length of 35mm, the camera would have a 350mm maximum focal length.

"Is 20/20 Vision ""Perfect"" Vision?" On most Snellen charts, the smallest letters correspond to 20/10 visual acuity. If you have 20/10 visual acuity, your eyesight is twice as sharp as that of a person with normal (20/20) vision. Your eye doctor or an assistant will use an instrument to show you choices of lenses to sharpen your eyesight.

iPhone 8 Most reviewers agree that the new cameras are one of the best new features in the iPhone 8 and iPhone 8 Plus. TechCrunch called them killer and said they're the best reason to upgrade this year, while CNET said the most noticeable change is the incredible quality of textures, largely due to Apple's new image signal processor.

Optical vs. Digital Zoom If you are comparing 2 digital cameras with the same optical zoom, but one has intelligent digital zoom and the other has traditional digital zoom, then the intelligent zoom has a slight advantage. But personally, I wouldn’t even look at that because there are a lot more important features to differentiate the cameras.

- They can easily accept larger objective lenses. Many scopes have variable power, which is indicated in their title. Instead of a 4 X 32 scope, you might see a 4 - 12 X 32 scope. In that case, the scope's magnification is variable from four to twelve power and the objective lens is 32 mm. 4-power scope enlarges the image four times. An 8-power scope enlarges things eight times, making it seem to be closer than when seen through a 4-power scope. That sounds good, but there are drawbacks to power. The higher the magnification, the less area you can see through the scope.

Microbiology SS12BMI Laboratory Experiments Using the Oil Immersion Objective. The only reason to use an oil-immersion objective is to take advantage of the highest resolving power available to the microscopist. Unless this is a necessary requirement of the work in hand, stay with the lower power dry objectives -- they are much less trouble to use, and can provide magnifications up to x600 (using a x40, 0.65 NA dry objective with x15 eyepiece) at quite acceptable resolution.

Short Description Superzoom Cameras. Super-zoom digital cameras provide a minimum of 8X zoom with some cameras offering as much as 30X zoom, most offer at least 15X zoom. These offer incredible levels of optical zoom so that you can get close to the action regardless of where you are.his is the scene at 4X zoom, In this case 4X is 56mm which is similar to the magnification of the human eye but a much smaller field of view. Example of a 4X Lens. This is the scene at 8X zoom, In this case 8X is 110mm which is slightly more than twice the magnification of the human eye.

- From the menus you can access in-camera HDR and Dynamic Range expansion settings, plus a series of digital filters. The Pentax 645D’s viewfinder is much larger than on a DSLR, making it easier to manually focus.Despite this, it offers only a 98% field of view, which seems unusual for such a professional product (though is better than the 92-93% FoV on older film models).entax 645D review – Performance. In poor lighting or low contrast scenes the camera does struggle to find focus and there is no AF illumination. In regular light however it performs without a quibble, locking on to the subject with ease. In manual focus there is an AF confirmation light in the viewfinder however.

Understand Camera Zoom Lenses Understanding Zoom Measurement. When looking at specifications for a digital camera, both the optical and digital zoom measurements are listed as a number and an X, such as 3X or 10X. A larger number signifies a stronger magnification capability.

optical zoom Main » TERM » O ». On a digital camera, optical zoom is a true zoom feature. It allows you to zoom in (or out) on the subject in the LCD or viewfinder. This will enable you to get a closer view of the subject before taking your picture. Optical zoom changes the magnification of images with the actual optical glass before the images reach the imaging sensor. Optical zoom allows for better photo quality than digital zoom.

- Welcome On board. In addition to the excellent opinions expressed above, maybe it is a good idea to make a point to test a used Zeiss FL 7x42. It faired very well in comparison to the Zeiss HT 8x42, and, with some persistence, an excellent sample could be found at less than half the recommended cost of the SF. Many in the forum here can give excellent reports on its brightness, stability, and it's closeness to 8x42 size binoculars. Enjoy in good health.

- Thanks for A2A. optical zoom = maximum focal length / minimum focal length. For example a 18-55mm lens would have a 3x optical zoom, and a 18-200mm lens would have a 11x optical zoom. The mm notation is the focal length. Note that when computing the zoom ratio (e.g. 3x, 5x) the units cancel so you can quote the focal length in inches, meters, AU and it won't influence the calculation.

Sony NEX-7 Review Again, we can see the NEX-7 does noticeably better than the A77 at ISO 1,600, despite using the same sensor. The loss of light through the transmissive mirror may be making the A77's noise reduction work harder at keeping noise levels in check, and/or there might be a different low-pass filter, tough to say.ive Sony E-mount lenses are already shipping in the US market: a 16mm f/2.8 prime, a 30mm f/3.5 macro prime, an 18-55mm f/3.5-5.6 stabilized zoom (available in a kit with the NEX-7 body), an 18-200mm f/3.5-6.3 stabilized zoom, and a 55-210mm f/4.5-6.3 stabilized zoom.
