Interchangeable Lens Cameras: Are They Worth The Hype?

DSLR cameras are a popular choice for photographers, offering the ability to swap out lenses for different purposes. While lenses are interchangeable in the sense that a camera can use different types of lenses (standard, wide-angle, macro, etc.), they are not completely interchangeable across different brands and camera types. This is mainly due to the lens mount, which is the part of the camera where the lens clicks into place. Each major company uses its own proprietary mount, so a lens from one brand won't fit another brand's camera without an adapter. Even with adapters, there may be limitations in lens functionality, such as slower autofocus or manual adjustments.

Mirrorless cameras are more compact than DSLRs

Mirrorless cameras are generally more compact than DSLRs. DSLRs are chunkier and heavier, with a prism and mirror system that makes them bulkier and heavier. The body of a Nikon D5600, for instance, is 2.8 inches deep before adding the lens. In contrast, mirrorless cameras, such as the Sony a6100, have bodies just 1.6 inches thick. This compact size allows mirrorless cameras to fit in small spaces like coat pockets or purses.

The weight difference is also significant. The Nikon D5600 with its kit lens weighs about 1.4 pounds, while the Sony a6100 with its kit lens is only 1.3 pounds.

The compact size and weight of mirrorless cameras make them easier to carry and more convenient for travel. They take up less space in a camera bag, leaving room for extra gear like additional lenses.

However, it's worth noting that some newer mirrorless cameras, especially those with full-frame sensors, are nearly as large and heavy as DSLRs, so the size and weight advantage may not always apply.

Lenses and Accessories

Mirrorless cameras often have smaller lenses, contributing to their compact form factor. This is particularly true for Micro Four Thirds cameras, which have sensors half the size of a full-frame chip, resulting in smaller lenses.

Additionally, mirrorless cameras usually have a shorter back-focus "flange" distance, which is the distance from the lens mount to the image sensor. This shorter distance allows for more compact camera designs.

However, when it comes to the range of lenses and accessories available, DSLRs have the advantage due to their longer history. They have been around for decades, so they offer a wider selection of lenses and accessories, including speedlights (flashes).

While there are exceptions, mirrorless cameras are generally more compact and lighter than DSLRs. This makes them easier to carry, travel with, and fit into small spaces. They also tend to have smaller lenses, especially those designed for Micro Four Thirds sensors. However, DSLRs offer a broader selection of lenses and accessories due to their longer history in the market.

DSLRs have a true-to-life view of the scene

DSLRs (or "digital single-lens reflex") cameras are a type of digital camera that has become synonymous with interchangeable lenses. They are a photographer favourite due to their flexibility, durability, and ability to pair with other lenses and attachments.

When light enters the camera lens of a DSLR, it is reflected by a mirror inside the camera body, allowing the photographer to see their subject in the optical viewfinder. When the photo is taken, the mirror swings out of the way, and the light goes through to the digital image sensor to capture the photo on an SD card.

This is different from mirrorless cameras, where the light goes directly to the image sensor, and the photographer sees what they are shooting via a rear LCD screen or an electronic viewfinder. The mirrorless camera's sensor sees the same exposure, allowing for fine-tuning of camera adjustments on the spot.

DSLRs, on the other hand, rely on the mirror for some of their focus, which can be problematic. The image that the DSLR's viewfinder sees may not be the same as what was exposed to the image sensor. This means that you might not get a good look at exactly what your camera captured until you start editing your shots.

Despite this discrepancy, DSLRs offer a true-to-life view of the scene through the optical viewfinder. This is because DSLRs use a mirror system, which reflects the light entering the lens, projecting it onto the viewfinder for the photographer to see. This mirror system is also what gives DSLRs their name, as they are "single-lens reflex" cameras. The mirror reflects light through a single lens, projecting it onto the viewfinder, hence the "reflex" in the name.

The mirror system in DSLRs offers a true-to-life view of the scene in front of the camera, which can be beneficial for certain types of photography. For example, wildlife photographers might prefer the optical viewfinder of a DSLR, as it provides a clear and uninterrupted view of the subject, without the potential lag or distortion that can sometimes occur with electronic viewfinders.

Additionally, the optical viewfinder in DSLRs can be advantageous in low-light situations. Mirrorless cameras, which rely on an electronic viewfinder, may struggle in very low light conditions, as the sensor has to work harder to produce an image. The optical viewfinder in DSLRs, on the other hand, will still provide a clear view of the scene, even in low light, as it is simply reflecting the available light.

Another benefit of the mirror system in DSLRs is the ability to use autofocus with optical viewfinders. While mirrorless cameras have autofocus as well, the autofocus system in DSLRs tends to be more advanced and reliable, especially in low-light or high-contrast situations. This is because the mirror system in DSLRs directs more light to the autofocus sensor, resulting in faster and more accurate focus.

In conclusion, while DSLRs may have some disadvantages compared to mirrorless cameras, they offer a true-to-life view of the scene through their optical viewfinders. This is due to the mirror system, which reflects light onto the viewfinder, providing a clear and uninterrupted view of the subject. This feature can be beneficial for certain types of photography, such as wildlife or low-light photography, where an uninterrupted and clear view of the scene is crucial.

DSLRs have a wider range of lenses

DSLR cameras offer a wide range of lenses, and this is one of their key advantages. While lenses are interchangeable, allowing photographers to use different types of lenses (standard, wide-angle, macro, etc.) with their camera, they are not always completely interchangeable across different brands and types of cameras.

DSLR cameras have a broader selection of lenses than other types of cameras, such as compact system cameras, which have a more limited range of compatible lenses. DSLR lenses are also designed to be adaptable to mirrorless cameras, which have become increasingly popular in recent years. This adaptability provides DSLR users with even more options for their photography.

When it comes to lenses, DSLR manufacturers typically offer a wide range of options designed specifically for their cameras. For example, Canon has its EF lens range for DSLR cameras, while Nikon offers F-mount lenses. These lenses are often not compatible with other brands, so a Canon lens usually won't fit a Nikon camera without an adapter.

The availability of third-party lenses further expands the lens options for DSLR cameras. Companies like Sigma, Tamron, and Tokina produce lenses that are compatible with DSLR cameras from major brands like Canon and Nikon. These third-party lenses provide additional choices for photographers, often at more affordable prices.

In summary, DSLR cameras offer a vast array of lenses, from those manufactured by the camera brand to third-party options. This wide range of lenses allows photographers using DSLRs to have greater flexibility and creativity in their work, making DSLRs an attractive choice for both amateur and professional photographers.

DSLRs have longer battery life

DSLR cameras offer longer battery life than their mirrorless counterparts. This is because the battery capacity of mirrorless cameras tends to be lower, as they are more compact and lighter than DSLRs. The electronic viewfinder of mirrorless cameras also uses up a lot of power.

DSLRs use lithium-ion batteries, which have a longer lifespan than the AA batteries used in early digital cameras. Lithium-ion batteries can be recharged at any time and hold their charge for longer. They also provide more accurate information about their remaining power.

The battery life of a DSLR will depend on how it is used and stored, as well as the number of times it has been recharged. On average, a DSLR battery should last at least five years. Some batteries for DSLR cameras that were released over a decade ago are still going strong.

To prolong the life of a DSLR battery, it is recommended to recharge it after each use and avoid letting it fully discharge. Extreme temperatures can also affect battery performance and lifespan, so it is best to avoid very hot or cold conditions.

DSLRs are more affordable

The fact that DSLRs have been around for so long, and are in many cases descended directly from even older analogue film cameras, means that the range of compatible bayonet-mount lenses they offer is enormous. Systems like Canon EF and Nikon F have huge catalogues of compatible lenses, not to mention tons of accessories like tripods, ball heads, and filters. Plus, with manufacturers' focus on mirrorless systems, the lenses are only likely to get cheaper as time goes on. DSLRs aren't just affordable upfront—they are a smart budget choice for thinking long-term.

DSLRs are also more affordable because they don't have the super-fast autofocus systems of mirrorless cameras, nor the dizzying, high-resolution video specs. However, if you don't need to be on the cutting edge of imaging tech—and most people don't—DSLRs are a superb camera choice.
