For relatively new photographers and digital slr owners it can be confusing when it comes to upgrading your kit lens. There are so many different lenses on the market covering a vast number of focal ranges and apertures that it can be very confusing to work out exactly which one you need.
This article will talk about what kind of things you should consider and will point you in the direction of one option that is little discussed about but has long been proved to be one of the best lenses out there as well as one of the cheapest!
You have so many decisions to make when trying to decide which lens to spend you money on. In my opinion the main thing you should look for in a lens is a wide aperture (or a low f number). A wide aperture give your two main benefits: firstly it lets a lot of light into the camera allowing you to take great shots in low light conditions without having to use the flash and secondly it lets you shoot with a cery shallow depth of field. A shallow depth of field lets you blur out backgrounds making close up or portrait shots stand out more and seem sharper.
Personally I feel that too many people place too much emphasis on aesthetics and certainly too much on zoom. After all why buy a lens with a huge zoom when you can zoom with your feet. OK some specialist photographers require a zoom (say for photographing tigers) however I would much rather get a higher quality lens with less zoom than the other way round.
In my opinion the best bet for a kit lens upgrade is the Canon 50mm f1.8. It is the cheapest lens Canon sell, the worst built, the lightest, the noisiest to focus but the optics inside produce absolutely stunning results.

If you're trying to become a professional photographer you might want to ditch the old camera and buy yourself a brand new SLR. Don't worry about choosing the wrong camera because below you'll find a great set of instructions that you'll find very useful while shopping.
SLR stands for single-lens reflex and if you're ready to make the big step toward it a 35mm will help you along the way. This is the best camera format for high-quality images and it's way better than wide-angle lenses, macro lenses or even zoom lenses.
On the other hand, a SLR camera is pretty expensive (almost $5,000) not to mention the rest of its accessories. Why is that? Because it simply offers the best control over the image. The technology behind SLRs uses regular 35mm films: black and white films, infrared films, transparency films and color negative films but you can also find a few models that still use 24mm Advanced Photo System films.
Autofocus vs. Manual Focus
Before buying a SLR you should decide if you want manual or auto focus (AF or MF). If you want AF you should know a few important details about these cameras:
- the electronics can let you down when you need them the most;
- the battery consumption is very high;
- the AF lenses can be pretty difficult to focus by hand especially when you want to switch to manual focus;
- the image provided by AF cameras is not exactly what you'd hoped for and that's mainly because of the limited range of their infrared beams;
- the autofocus is not very silent compared to the manual focus;
- the AF lenses are very often surrounded by plastic components that are not as durable as you may think.
If you use a manual focus you'll see that you'll be the one setting the focus, the shutter and the aperture and for most photographers that's simply great.
A few great manufacturers like Nikon, Pentax and Olympus use few electronics when making a manual focus SLR and this will help you better understand how all this works. Last but not least, a manual camera is considerably cheaper than an autofocus one.
To sum up all the above it's very important for you to know exactly what type of focus you want to use because otherwise you'll be spending a lot of money on a camera that won't be able to make the pictures you want.

Thousands of camera buyers buying their first SLR can't be wrong right? If voting with your dollars counts, then I reckon the Canon Rebel XSi would be the best SLR entry level camera on the market today. Some may disagree, and quibble over which Canon Rebel should be the winner (the T1i is a contender), but it's really a matter of how deep is your pocket book.
Single lens reflex (digital single lens reflex) cameras provide many rewards over traditional point and shoot cameras, not the least of which is the power to use various lenses. Numerous photographers world wide pick single lens reflex cameras for the creativity multiple lenses offer. Those enthusiasts that won't use a DSLR camera end up staring at a skewed representation of their impending photograph. It's not so bad, if you ignore the zoom option, but things could be tougher if you try to zoom a picture and are having issues with focal length. The single lens reflex is best because the viewing and picture taking lens are in synch.
While DSLR purists may be staging a revolt, the conclusion by most camera manufacturers including Pentax and Fuji to allow consumers to use the LCD or viewfinder to shape their scenes is a great thing.The first step in Live View, is to utilise an additional supplemental sensor to apply the image being delivered from the prism mirror. That supplementary sensor image, will commence to buffer and send the perspective photograph to the view screen. While live view has been a hot item, it often meant forgoing autofocus which was unfortunate. The the newer Canon Rebel has made some inroads towards compensating for this.
DSLR Camera Types
DSLR With Interchangeable-lens
When the best SLR entry camera is cited, it's this type that most individuals would associate with. For this article, these are the ones we will be hashing out here. Like most professional DSLR cameras the type of lens you can choose, is entirely up to you. Whatever the photographic surroundings needs can be accommodated with a digital single lens reflex camera that allows for a variety of lenses.
Any of the Canon Rebel cameras, as well as the Nikon D40, D60, and D90 grace this category.
Do DSLR Cameras Come With Non Changeable Lenses?
If you wanted the features of a SLR without the scuffle of lugging a truck load of lenses, you have some selections. While this single lens reflex camera type would have been popular a few years ago, tech has moved ahead, and they have become virtually non existent.
Given the competitive nature of the best SLR entry level camera market, I've found the price and choice I want by shopping on the web. Small local camera boutiques simply can't compete with their high overhead and small makes and selection.

Simply put depth of field (DOF) is how much of the photograph in front of and behind the main subject that is in focus. This however is not an even distribution. The range is approximately 1/3 in front of the main subject and 2/3 behind it.
To maximize your DOF do not focus right on your main subject. Focus 1/3 of the distance into the scene with the lens aperture set to the smallest possible. The part most people have difficulty with is how do you change the depth of field and why would you want to?
So let us find out.
The DOF can be shallow, with the main subject in sharp focus and the foreground and background out of focus. It can also be deep, with the foreground, the main subject and the background all in focus.
The three main factors to determine DOF are:
The focal length of the lens
The distance from the camera to the subject
The aperture or f-stop of the lens
How to change the DOF.
1. By changing the focal length.
A lens with a long focal length, such as a telephoto lens has an angle of view that is narrower than a lens with a shorter focal length. This results in a shallower DOF.
A lens with a short focal length, such as a wide-angle lens means a greater DOF. These shorter lenses have a greater angle of view, which results in the increase to the DOF.
2. Change the distance from the camera to the subject.
You can achieve the same result by moving the camera. The closer to the subject it is the shallower the DOF and the farther away the deeper the DOF.
3. By changing the aperture.
Changing the aperture (also referred to as the f-stop) will also change the DOF. A larger f-stop means a smaller aperture, which results in a larger DOF and a smaller f-stop will result in a larger aperture and shallower DOF.
Keep in mind that when you change the aperture you will also need to change the shutter speed.
When the f-stop is increased, decreasing the amount of light reaching the sensor, you will need to increase the time the sensor stays energized to compensate.
If you do not slow the shutter speed down the image may be too dark.
This may seem a little involved if you are just getting started but do not worry. Check your cameras manual for the semi-automatic settings.
If you chose the aperture priority (AP) setting, sometimes referred to as aperture value (AV) and select the f-stop you wish to use, the camera will automatically set the shutter speed for you.
When a slower shutter speed is selected be sure to use a tripod in order to prevent camera shake.
Why change the DOF.
There are times when you want the whole frame to be in focus such as a landscape shot. In this case set a large f-stop, for example f-22. This will close down the aperture and result in a greater DOF.
At other times you will want to keep only the main subject in focus. For example when photographing a small bird you want to keep all the attention on the main subject and not the surroundings. For this example set a small f-stop, f-2.8 which will open up the aperture and result in a shallow DOF.
To summarize. You should now have a pretty good understanding of depth of field.
For a greater DOF use a wider-angle lens and larger f-stop, or you could position the camera farther away from the subject. You can also use a combination of these two methods.
If you want a shallower DOF, then use a longer focal length lens and smaller f-stop, or position the camera closer to the subject.
Once again you could also use both of these methods in combination.
Play with the settings on your camera to see these results with your own photography. Just keep in mind, no matter what type of lens you are using, the larger the f-stop, the smaller the aperture, which results in a greater depth of field.
The inverse is also true. The smaller the f-stop, the larger the aperture is, which results in a shallower DOF.
There is no better way to understand what to do than by actually doing it.
