DSLR CAMERA GUIDE

______________________________________________________________________________
Common “point-and-shoot” cameras with fixed lenses (lenses that may not be removed and
changed for other lenses) are not acceptable for course use, as they do not typically offer manual
control of basic camera functions or adequate range of aperture control. This lack prevents users
of such cameras from completing required course assignments.
While you may choose to use a digital camera not on the list, please make sure any DSLR
camera selected has manual control of aperture, shutter speed and focus. In addition, the
instructors cannot possibly be familiar with the wide range of cameras that may potentially be
selected, and therefore may be unable to help you with the camera controls and menus if you do
not also have the instruction manual for the camera.
Cameras all cameras need to have manual exposure and focus controls
Almost any DSLR made in the past 3 years will suffice.
Suitable Examples of DSLRs:
Canon DSLR Rebel T3i, T4i, T5i, T6i, and T7i
Nikon DSLR D3200, D3400, D5200, D5600 & pro DSLR
Olympus DSLR – E-5
Pentax DSLR – K-5, K-30, K-50
Sony DSLR SLT A35, A37, A57, A58, A68
Why a digital SLR?
So you've decided to invest in a new digital
camera and have made your mind up that
you want to step up to a digital SLR, but
the huge range of models on offer and
endless flow of technical jargon have left
you more confused than when you started?
Fear not, this page will take the pain out of
choosing the perfect digital SLR for you,
whether you're a seasoned shooter or a
total novice.
Before we get down to business it's worth
stopping for a moment to ask the question:
why would anyone want a digital SLR
when compact digital cameras are so much
smaller, lighter and more affordable? The
answer can be summed up in two words: versatility and image quality.
The versatility isn't just the fact you can change lenses and add a wide range of accessories - from basics
such as flashguns and remote controls to the more specialized equipment that allow SLRs to capture
anything from the tiniest bug to the most distant stars. It's also about the creative versatility offered by the
more advanced controls and higher quality components.
And this leads on to the second factor; image quality. In broad daylight the quality difference between a
good compact and a digital SLR is minimal; both will produce sharp, colorful results with little effort. But

Why a digital SLR?

So you've decided to invest in a new digital camera and have made your mind up that you want to step up to a digital SLR, but the huge range of models on offer and endless flow of technical jargon have left you more confused than when you started? Fear not, this page will take the pain out of choosing the perfect digital SLR for you, whether you're a seasoned shooter or a total novice. Before we get down to business it's worth stopping for a moment to ask the question: why would anyone want a digital SLR when compact digital cameras are so much smaller, lighter and more affordable? The answer can be summed up in two words: versatility and image quality. The versatility isn't just the fact you can change lenses and add a wide range of accessories - from basics such as flashguns and remote controls to the more specialized equipment that allow SLRs to capture anything from the tiniest bug to the most distant stars. It's also about the creative versatility offered by the more advanced controls and higher quality components. And this leads on to the second factor; image quality. In broad daylight the quality difference between a good compact and a digital SLR is minimal; both will produce sharp, colorful results with little effort. But when you start to push the boundaries a bit more; shooting in low light, attempting to capture fast moving sports action or wildlife, or when you want to experiment with shallow depth of field (to add a soft

background to a portrait for example), the advantage of a digital SLR's larger sensor and higher sensitivity start to make a big difference. A digital SLR can't beat a compact camera for 'pop it in the purse or pocket' convenience but for serious photography the DSLR wins hands down. With prices lower than ever it's not that surprising to discover that many people own one of each.

What is an SLR?

The basic physical design of the SLR has remained essentially unchanged for over half a century. The name itself, 'Single Lens Reflex', refers to the hinged mirror that bounces the light passing through the lens up to the viewfinder for framing then flips out of the way when you press the shutter to allow the light to hit the sensor (or film). As the (simplified) diagram above shows, the mirror inside an SLR reflects the image formed by the lens up to the optical viewfinder (via a focusing screen and prism). When the picture is taken the mirror flips out of the way to allow the light to fall directly onto the sensor (or film), which sits behind a mechanical shutter. The mirror is also flipped up for live view operation (where the sensor is used to provide a live video feed directly to the screen on the back).

What do you need?

With so many digital SLRs on the market at so many different price points it's a good idea to narrow down your options by thinking about what 's important to you, and what you want to do with the camera. Do you want the same kind of 'point and shoot' simplicity as you get with a compact camera or are you the type of photographer who likes to roll up his or her sleeves and take control of every function? Many entry-level DSLRs offer a range of 'point and shoot' subject / scene modes, whereas more 'professional' models don't (though all have a basic 'auto' program mode). Do you shoot a lot of sport or wildlife? If so you'll need a fast camera with a high frame rate, and will probably want one of the smaller sensor formats. If you shoot in very low light you'll be looking for a camera with the best possible high ISO performance and possibly in-body image stabilization, if you do a lot of studio, portrait or macro work you may well decide that a 'live view' function is a high priority.

because there's no crop factor are often chosen by photographers who are upgrading from a film SLR and already own expensive wide-angle lenses. The larger sensor also means that - all other things being equal - full frame cameras will produce the best results in very low light and at higher sensitivities. On the downside, full frame cameras are big and expensive, and there is only a handful of models to choose from. You also lose the focal length 'boost' offered by smaller sensor cameras when shooting with telephotos. The larger the sensor the easier it is to get very shallow depth of field effects. The flip side of this is that it can be harder to get everything in focus when you do want to. Overall though, the larger sensors offer more control over depth of field for those that know how to use it. APS-C is by far the most common format, used in virtually all Canon, Nikon, Pentax and Sony DLSR models. With a crop factor of 1.5x or 1.6x you need special digital lenses to get true wide-angle results, but these are readily available and are usually less expensive than their 'full frame' counterparts. The 'kit lens' supplied with most APS-C cameras is a good starting point, offering a versatile zoom range from wide- angle to short telephoto. The difference in size and weight between a full frame professional level camera (Nikon D3, left) and a compact entry-level DSLR (Nikon D60, right) is considerable. The Four Thirds system promises slightly more compact camera bodies and lenses. Four thirds is also the only DSLR system that uses the slightly squarer '4:3' format (as used on virtually all compact digital cameras). Four Thirds is a new 'all digital' format developed by Olympus and currently used in Olympus and Panasonic DSLR models. Unlike the other systems on the market Four Thirds is not based on any existing film SLR system and uses a totally new lens mount, so all the lenses in the system are designed for digital, making the crop factor issues mentioned above less relevant. With the smallest sensor size Four Thirds offers slightly more compact camera bodies and lenses. Although the smaller sensor should in theory mean that these cameras produce noisier (grainier) results in low light and at higher sensitivities, for most purposes the difference isn't huge.
