How Do You Know if Your Iphone Camera Lens Has Moisture
Swapping out lenses is 1 of the greatest advantages of modern photography, allowing for photographers to accept vastly different kinds of pictures with the same camera. Simply what should yous know earlier you buy an expensive new lens?
It's important to ask yourself the right questions earlier making a major buy, as even cheaper lenses tend to exist pretty expensive. We'll run down some of those important questions and help readers understand what they're looking for before they commit to a new lens.
Exercise I Have the Correct Kind of Camera?
Many cameras aren't equipped with what we call "Interchangeable Lenses." Those professional looking, big SLR cameras, digital SLRs, and the MILC cameras we discussed last calendar week are the ones we'll exist looking at today. Point-and-shoot cameras have fixed lenses, and are engineered to accept the ability to have adept snapshots with a so-called "normal" lens. Chances are, if your camera came with a lens, it is a normal lens, made to replicate an paradigm similar to the one produced by the man centre. But cameras aren't like human eyes—they can exist made to do things that our eyes aren't very adept at. Interchangeable lenses (metaphorically) add together more colors to the palette of clever photographers, allowing to tailor a lens to a certain kind of shot they promise to reproduce. This is the advantage of DSLR, SLR, and MILC cameras over point-and-shoot, and not whatever astonishing departure in epitome quality caused by larger camera bodies or more megapixels. Let's take a quick look at the kind of info interchangeable lens camera owners need before shelling out lots of cash for new lenses.
What Type Of Lens Do I Want?
In that location are three major types of lenses, but today nosotros'll be talking almost 2 others, just for the sake of being thorough. The three main types are normal lenses, telephoto lenses, and broad bending lenses. The other two types are specific types of wide angle and telephoto lenses, fabricated for special kinds of photography—macro lenses, and fish eye lenses. This is the starting time important question you should inquire yourself—what do I want to buy a new lens for? Let's briefly talk almost how each lens is used, and why you might desire to buy 1.
Normal Lens: All lenses are differentiated by their focal length, or the distance it takes for light to criss-cross and focus on the photosensitive material inside, be it film or a sensor. Like we've said, normal lenses are made to create pictures similar to the images you meet with your eyes, and take a focal length of effectually 50mm for the so-called "standard" format. Cropped format DSLR cameras will crave a smaller focal length, but that'south a circuitous subject field we don't have time for today. Any lens you buy should tell yous if information technology is a normal lens for the format y'all're shooting or not—more on that afterward.
Wide Angle Lens: Lenses with shorter focal length (around 35mm and less) allows for low-cal to strike at the photosensitive material more easily, allowing for a greater angle of view in your image. Broad angle shots will capture more image from a wider field of view when shot from the same spot. They besides have greater depth of field, allowing you to keep clean, tighter focus on more than parts of the image, even in epitome data nigh and far. The shorter the focal length, the tighter the focus. Very wide angle lenses also create prototype baloney, which is a expert lead in to our adjacent topic.
Fish Eye Lenses: When lenses have incredibly short focal length, they fall into a sub-category of wide angle called "fish middle" lenses. These lenses squeeze then much information into the aforementioned image format that they greatly distort the images, and create a bizarre, otherworldly effect we've probably all seen in movies. Fish Eye Lenses are fun, but are not widely used in photography, except as a novelty.
Long Focus or Telephoto Lenses: These lenses are the ones that really seem to impress people—huge barrels of glass, metal and plastic mounted on a professional looking camera torso will make an impression on merely about anybody. Turns out telephoto lenses are some of the most useful to take certain kinds of photos. It seems a given that these kinds of lenses are expert for long range shots, but you may exist surprised that many of these lenses are perfect for intimate portrait photography. Lenses of effectually 85-100mm are sometimes chosen "portrait lenses" considering they can finer eliminate the distortion of shorter focal length lenses, and keep faces looking natural. They likewise allow photographers to go on a skilful standard distance of 10-fifteen feet from a subject and however get a tight, intimate shot. And photographers interested in bokeh shots will exist happy to know that the smaller depth of field is perfect for bokeh.
Macro Lenses: Some telephoto lenses are especially designed to focus in on smaller objects, and we call these macro lenses. There'south not a lot to be known nearly this, except that telephoto lenses are expert for extreme closeups and photographing small objects as well as taking shots of distant images.
How "Fast" Does My Lens Need to Be?
When you wait at the info on an online listing of a lens, you might notice that information technology also includes the f number of the lens, or two in the example of zoom lenses. This refers to the maximum aperture of the lens, or past some terminology, the speed of the lens. The lower the f number, the wider the discontinuity, the more light the lens allows in. A lower f number on the lens means that you tin can utilise lower ISO and faster shutter speed settings, so a drop in f number (especially on zoom and telephoto lenses) ways a dramatic increase of quality in the lens (and probably expense!). Longer telephoto lenses allow in narrower, more intimate images, but also block more lite and accept smaller f numbers. All other things equal, get the smallest f number you can afford.
What Format Am I Shooting In?
Digital photography has created a trouble, in that it has created lots and lots of new "formats." Film simply photographers won't have to worry near formats, considering almost every SLR that uses film will be using the 35mm format. Digital photographers have to deal with cropped sensor formats, and have to employ lenses designed to create clean images on sensors smaller than the 35mm paradigm area.
Yous might purchase a lens for the wrong format, simply you lot'll near likely be returning it if you do. Most lens mounts don't allow for cameras to use lenses for the incorrect format, with one notable exception. Nikon is particularly proud of the fact that it uses a standard mount for its interchangeable lenses (information technology has for many years), and so a photographer might exist tempted to use the wrong format lens. This is never actually a good idea, as the incorrect format lens can bear upon your photographic camera's ability to resolve detail properly or create an improperly cropped paradigm. (Experience costless to ask questions virtually this—if there'southward involvement, we'll probably be writing an explainer nigh this very confusing topic.)
You likely won't have this problem when shopping for lenses—merely google "lenses for " and so your camera model to get an idea of what to start looking for. It'south very (very) likely non going to sell as a lens for that camera if it's in the wrong format!
What Do Other People Think?
This is a critical pace, and an obvious i, just we'll briefly talk about it anyhow. Just like any slice of software or hardware, read lots of reviews before making a buy. Information technology'southward important to be well informed before sinking a couple of hundred bucks into a new lens. But keep in mind what the reviewers are saying. What level do they audio like they're at? Are they describing the kinds of pictures you lot want to take? Are they taking pictures in the kinds of situations you're taking pictures in? Really call back about if the lens is a adept fit or not, from the perspective of accomplishing what it needs to attain.
Does the lens resolve detail well? Does it have whatever anti-shake, or other technology? It's amazing to recall of the level of engineering science that goes into a lens to create a quality prototype, so spend plenty time reading both professional person and customer reviews to exist sure you truly understand what you're getting. Here's a quick example. An aftermarket telephoto lens for a Nikon camera might be excellent at resolving detail and toll three hundred dollars less than a comparable Nikon lens, but might take some foreign quirks (Author'southward note: I've seen a zoom lens that would slide forwards and backward, ruining an image, unless information technology was held in place by manus). Reviews tin brainwash you about these problems then you can make up one's mind if the actress few hundred is worth all the frustration, or the minor frustration is worth saving a few hundred.
How Much Apply Will I Leave of This Lens?
This is always one of the near important questions to inquire before committing to that lens. Are y'all going to get a lot of use out of it? Do you need to take portrait or long range shots? Exercise you really demand to accept goofy fish-centre lens images? If you've got money to fire and photography is a passion for you, get bananas and purchase all the lenses yous think yous can apply. Keep in listen that new lenses will not brand you a better lensman, just they can help you take a unlike kind of picture.
