8 Reasons You Should Buy a DSLR Camera Today (And Which Are Best)

Are you an aspiring photographer looking to elevate your craft? Or maybe you‘re a seasoned pro in need of a reliable, high-performance imaging tool. Whatever your skill level or ambitions, one thing‘s certain—for many, a DSLR camera remains an essential part of any serious photography kit.

DSLR, which stands for "Digital Single-Lens Reflex," is a camera design that has dominated the digital photography landscape for over two decades. And while mirrorless cameras have been generating a lot of buzz lately, DSLRs still have a lot to offer, especially for photographers who prioritize image quality, speed, and a robust ecosystem of lenses and accessories.

How a DSLR Works

At the heart of a DSLR is the mirror-based optical viewfinder system adapted from old-school film SLRs. When you look through a DSLR‘s viewfinder, you‘re seeing a reflected image directly from the lens, courtesy of a mirror that sits in front of the shutter and image sensor.

When you press the shutter button, that mirror flips up out of the way, the shutter opens, and light from the lens reaches the sensor, capturing the image. This mechanical mirror mechanism is what gives DSLRs their signature "clack" shutter sound and also allows for the use of optical "through-the-lens" (TTL) autofocus and metering systems.

The DSLR Advantage

So what makes this tried-and-true DSLR design so compelling for photographers even today? Here are eight key advantages:

1. Superior Image Quality

The single biggest reason to choose a DSLR over a compact camera or smartphone is image quality. Most DSLRs feature large APS-C or full-frame sensors that dwarf those found in point-and-shoots. These bigger sensors can collect more light, producing images with higher resolution, wider dynamic range, and less noise at high ISOs.

Full-frame DSLRs, in particular, are prized for their ability to deliver professional-grade image quality even in challenging lighting. Top models like the Nikon D850 boast massive 45+ megapixel sensors that capture stunning levels of detail and color gradation. And with the latest sensor designs like backside-illumination (BSI), today‘s DSLRs deliver cleaner results than ever at ultra-high ISOs.

2. Vast Lens Selection

Another huge draw of DSLRs is access to an extensive selection of interchangeable lenses. Unlike point-and-shoots or smartphones that are limited to a fixed lens, DSLRs can be used with a wide array of lenses designed for different subjects and shooting situations.

The major DSLR manufacturers, Canon and Nikon, both have massive lens lineups for their respective mount systems (EF and F). These span everything from ultra-wide zooms to super telephotos, fast primes to specialized macro and tilt-shift lenses. Many of these are professional-grade "L" or "Gold Ring" lenses that deliver exceptional sharpness, color rendition, and build quality.

3. Blazing Fast Autofocus

When it comes to nailing focus quickly, DSLRs have a big edge over most compact cameras. That‘s because DSLRs use dedicated phase detection autofocus (PDAF) sensors for viewfinder shooting. These specialized AF sensors can evaluate the distance to the subject and adjust focus extremely rapidly.

The latest flagship DSLRs like the Canon 1D X Mark III and Nikon D6 boast phenomenally dense and responsive AF systems. The D6, for instance, has a 105-point all-cross-type AF system that can focus down to -4.5 EV. Combined with DSLR‘s bright optical viewfinders, these sophisticated AF systems make it easy to track fast, erratic movement, even in low light.

AF Performance Comparison (flagship models)
Model | AF Points (Cross-type) | Low Light Sensitivity
——|————————|—————————–
Canon 1D X Mark III | 191 (155) | -4 EV
Nikon D6 | 105 (105) | -4.5 EV

4. Low Light Prowess

Speaking of low light, this is another area where DSLRs truly excel. Their large sensors allow for much better high ISO performance than compact cameras or smartphones. Modern full-frame DSLRs can practically see in the dark, with many offering extended ISO ranges up to 102,400 or higher.

But it‘s not just about the quantity of light; DSLR sensors also produce much higher quality results at elevated ISOs. Advances like on-sensor noise reduction and backside illumination (BSI) help to maintain dynamic range and color fidelity while fighting unsightly noise and banding. Coupled with fast glass, a good DSLR will let you keep shooting handheld long after the sun goes down.

5. Depth of Field Control

DSLRs also give photographers far more creative control over depth of field. Depth of field refers to the range of distance in an image that appears acceptably sharp. A shallow depth of field, where the background is blurred, is often used for portraits and artistic effect. A deep depth of field, where foreground and background are both in focus, is more common for landscapes and architecture.

Depth of field is primarily controlled by lens aperture, and this is where DSLRs really shine. Their larger sensors allow for much greater background blur at wide apertures compared to point-and-shoots. And DSLR lens lineups include many fast aperture primes and zooms (e.g. f/1.4, f/1.8, f/2.8) that excel at subject isolation. Combined with precise aperture control, DSLRs give photographers immense flexibility in manipulating depth of field for creative effect.

6. Action-Freezing Shutter Speeds

In addition to aperture, DSLRs also provide complete control over shutter speed. This allows photographers to either freeze fast motion or deliberately blur it depending on their artistic intent. Sports and wildlife shooters, in particular, rely on super-fast shutter speeds (1/1000s, 1/2000s, or shorter) to capture tack-sharp images of moving subjects.

Top-tier DSLRs also boast incredibly fast continuous shooting speeds. The Canon 1D X Mark III, for instance, can rattle off full-resolution RAW images at up to 20 frames per second. Combined with sophisticated predictive autofocus algorithms, this allows photographers to capture the decisive moment even with fast, erratic subjects.

Max Continuous Shooting Speed (flagship models)
Model | Max RAW Frame Rate
——|——————-
Canon 1D X Mark III | 20 fps
Nikon D6 | 14 fps

7. Optical Viewfinder Experience

While electronic viewfinders have come a long way, many photographers still prefer the experience of a DSLR‘s optical viewfinder (OVF). With an OVF, you get a clear, lag-free view directly through the lens. There‘s no screen glare to contend with, no pixel grid, and no hunting in low light.

That direct viewfinder connection also makes it easier to stabilize the camera for steadier handheld shots. Composing through the viewfinder provides an additional point of contact compared to holding the camera at arm‘s length. This is especially beneficial when using longer, heavier lenses.

8. Robust Build Quality

Lastly, DSLRs are typically built to withstand the rigors of daily professional use. Higher-end models feature full metal alloy bodies with extensive weather sealing against dust and moisture. Shutter mechanisms are rated for hundreds of thousands of actuations. And critical controls are large, tactile, and easy to operate even with gloves on.

This robust build quality means that a well-maintained DSLR can last for many years of heavy use. It‘s not uncommon for professional photographers to use the same DSLR body for several generations before feeling the need to upgrade. This longevity can help offset the higher initial cost of a DSLR system.

Choosing the Right DSLR

So which DSLR should you buy? The answer depends on your specific needs and budget. But here are some top recommendations in several key categories:

Best Overall DSLR: Nikon D780

The Nikon D780 is a superbly well-rounded DSLR that excels at both stills and video. It features a 24.5MP full-frame BSI sensor, fast 51-point AF system, and uncropped 4K video with 10-bit output.

Best DSLR for Beginners: Canon Rebel SL3

The Canon Rebel SL3 (250D) is a fantastic entry-point into the DSLR world. It combines approachable ease of use with a very capable 24.1MP APS-C sensor, fast Dual Pixel autofocus, and 4K video recording. The guided menu system is great for beginners, while the traditional control layout allows room to grow as your skills develop. And at just 15.8 oz, it‘s one of the lightest and most portable DSLRs around.

Best DSLR for Professionals: Canon 1D X Mark III

For professional photographers who need the ultimate in speed and reliability, it‘s hard to beat the Canon 1D X Mark III. This flagship DSLR boasts a 20.1MP full-frame sensor, 191-point AF system, and blistering 20 fps continuous shooting with autofocus. It also offers 5.5K RAW video, a 400,000-shot shutter life, and built-in ethernet for faster file transfer. All of this is packed into a bombproof magnesium alloy body with extensive weather sealing.

Best DSLR for Multimedia: Nikon D850

If you‘re looking for a DSLR that can do it all—stills, video, timelapse, you name it—the Nikon D850 is a top choice. It combines a high-resolution 45.7MP full-frame BSI sensor with 7 fps continuous shooting, 4K UHD video, and an 8K timelapse mode. The tilting touchscreen is great for video and low-angle shooting. And like other top-tier Nikon DSLRs, the D850 is built like a tank, with a rugged magnesium alloy body and extensive weather sealing.

The Future of DSLRs

So where do DSLRs go from here? With mirrorless cameras generating much of the buzz these days, some have questioned whether DSLRs are a dying breed. But while mirrorless technology continues to advance rapidly, DSLRs are far from obsolete.

In fact, many professional photographers continue to prefer DSLRs for their unmatched viewfinder experience, robust lens ecosystems, and proven reliability. And manufacturers are still investing in DSLR technology, as evidenced by recent releases like the Canon 1D X Mark III and Nikon D780.

Looking ahead, DSLRs are likely to continue evolving and incorporating more advanced features from the mirrorless world. Things like on-sensor phase detect AF, in-body image stabilization, and high-res electronic viewfinders could eventually make their way into DSLR designs.

But even as mirrorless cameras gain ground, DSLRs are likely to maintain a significant presence in the camera market for years to come. They remain an excellent choice for photographers who prioritize image quality, speed, and lens selection, and who prefer the traditional shooting experience of an optical viewfinder.

Getting the Most from Your DSLR

To wrap up, here are a few tips for getting the most out of your DSLR:

Experiment with different shooting modes: DSLRs offer a variety of exposure modes, from fully automatic to semi-automatic (aperture priority, shutter priority) to fully manual. Experiment with these to understand their effects and take control of your exposure settings.
Learn to read the histogram: The histogram is a graphical representation of the tonal distribution in your image. Regularly checking the histogram can help you to identify and correct exposure problems before you take the shot.
Shoot RAW for maximum flexibility: RAW files contain all of the unprocessed data captured by your DSLR‘s sensor. Shooting RAW gives you far more leeway to adjust things like white balance, exposure, and color after the fact without degrading image quality.
Master your autofocus modes: Most DSLRs offer several different autofocus modes optimized for different subjects. Single-shot AF is great for stationary subjects, while continuous (AI Servo) is better for moving subjects. Many DSLRs also offer automatic subject tracking and face/eye detection.
Use exposure compensation: Exposure compensation allows you to quickly adjust your exposure up or down to account for tricky lighting situations. It‘s a great way to fine-tune your exposure without having to switch to full manual mode.
Back-button focus: Many DSLRs allow you to decouple autofocus from the shutter button and assign it to a rear button instead. This "back-button focus" technique allows you to control focus and shutter release independently for more precise control.

Conclusion

DSLRs may not be the flashiest or trendiest cameras on the block anymore. But they remain an indispensable tool for many serious photographers thanks to their excellent image quality, speed, lens selection, and ergonomics.
