Those, who are new to the art of photography, are often confused by the terms SLR and DSLR while buying a camera. They have no idea about the differences between these two types. In this write-up, we have made comparison between these two types based on some important criterion to help you understand the real differences between them.

Technology

Both SLR and DSLR cameras use single-lens reflex technology that makes a good use of internal reflex mirror to help the users see what the camera is able to capture through its optical viewfinder. On this ground, DSLR offers a little more advantage over SLR. Some DSLR cameras have rear LCD screen to provide live digital viewing.

Image Sensor

Sensor is another most remarkable difference between these two cameras. SLR cameras are versatile analog/film models. The letter ‘D’ preceding SLR stands for Digital and was added only after SLRs with digital sensors were developed. Digital SLRs or DSLRs save thousands of images in their memory cards whereas SLRs shoot a particular number of images for each roll of film.

Physical Properties

With emergence of modern versions of SLR and DSLR cameras, it gets more difficult to identify the cameras only by their appearance. Traditionally, SLR models feature two-tone colors, more buttons and have no rear monitors. On other hand, digital SLRs tend to have mono color and a monitor. SLRs, made of more metal, feel heavier than DSLRs. 

Interchangeable Lens Feature

Unique imagine technology has made it possible for both types of cameras to use interchangeable lenses. It enables the users to equip their SLR or DSLR models with lens choices based on unique shooting styles and imaging requirements.

Video Capability

Thanks to advances in modern technology, DSLR cameras are able to record videos – a great feature conspicuously absent in SLRs.

Resolution & Quality

Film cameras ensure better image quality in terms of dynamic range, contrast and colour. On these points, even the most advanced digital cameras lag much behind the film cameras. If the available types of analog and film sensors are taken into consideration, SLRs offer great pixel outputs than many consumer digital SLRs.

Price & Value  

These days, more digital SLR models are available in the market and it has led to a drop in their price. If value and cost are preferred to convenience, SLRs are a far better option as they don’t need an upgrade like DSLRs do.

Our Suggestion

Before investing in any type, you should consider your shooting style, personal choice and affordability. Evaluate which factors make a priority for you and decide whether an SLR or a DSLR makes a better investment in your case.
