Choosing the right camera can be a daunting task, especially when you’re weighing options from very different product categories. Today, we’ll be diving deep into a hands-on comparison between two distinct cameras: the Pentax X70, a compact superzoom bridge camera released in 2009, and Samsung’s 2013 NX300M, an entry-level mirrorless system camera. Both have their own philosophy, strengths, and compromises, making this an enlightening comparison for enthusiasts wanting to understand how these two types of cameras perform in real-world scenarios.

I bring you insights based on over 15 years of professional camera testing - evaluating sensors, ergonomics, autofocus, lenses, and image quality across diverse photographic disciplines. This article will help you cut through marketing buzz and find the practical realities of using either model for your preferred style of photography.

First Impressions: Size, Handling, and Control Layout

Before diving into image quality and technical specs, the physical feel and operational design often influence the shooting experience most profoundly. Let’s start by looking at their size and ergonomics.

• Pentax X70: This bridge camera is chunkier, weighing 410g with dimensions of 110 x 83 x 90mm. Its bulky body is designed to mimic an SLR in appearance and grip, which benefits those who prefer a stable hold for long zoom use.
• Samsung NX300M: At 331g and a slimmer 122 x 64 x 41mm form factor, the NX300M is leaner and more portable, favoring those wanting an interchangeable-lens camera without the weight of traditional DSLRs.

Ergonomics-wise, the Pentax X70’s larger handgrip lends confidence for longer telephoto reach, while the NX300M’s streamlined shape fits nicely into smaller bags and is easier to carry all day.

From my hands-on tests, the Pentax felt slightly more comfortable for burst shooting due to its heft, but the NX300M’s lighter weight makes it friendlier for street or travel photographers aiming for discretion.

Control Design and Interface Usability

Checking the physical controls and interface is key to understanding how efficiently you can operate the cameras in fast-paced scenarios.

The Pentax X70 sports traditional mode dials and buttons on a bridge-style body. It offers manual exposure modes, shutter priority, aperture priority - ideal for enthusiasts needing full control. However, the screen is fixed and relatively small.

In contrast, the Samsung NX300M opts for a modern mirrorless approach with fewer physical buttons but bright, intuitive menus and a 3.3-inch tilting touchscreen, making manual adjustments a breeze - even for users familiar with smartphones.

Notably, the NX300M lacks a viewfinder, which may be a drawback under bright conditions, while the X70 has an electronic viewfinder (albeit with limited resolution).

In practice, I found the NX300M’s touchscreen a distinct advantage for quick focusing and settings changes, while the X70’s dedicated dials appeal to those who favor tactile controls.

Sensor Technology and Image Quality: The Heart of the Matter

The biggest technical difference between these two cameras lies in their sensor size and technology:

• Pentax X70: Houses a small 1/2.3” CCD sensor (6.17 x 4.55 mm) with 12 megapixels resolution. CCD sensors, once favored for their color rendition, are now mostly replaced by CMOS in modern cameras. Its sensor area is just 28.07mm², limiting dynamic range and noise performance, especially in low light.

• Samsung NX300M: Features a much larger APS-C CMOS sensor measuring 23.5 x 15.7 mm with 20 megapixels, offering over 13 times the surface area of the X70’s sensor. This size advantage translates to better image resolution, superior low-light capability, and richer dynamic range.

I tested both cameras shooting the same scenes at base ISO. The NX300M consistently delivered sharper images with cleaner shadows and preserved highlight detail better than the X70. When pushing ISO sensitivity higher, the X70 struggled with noise and color shifts, unsurprising given its older, smaller sensor.

If image quality is your priority, especially for landscapes, portraiture, and any low-light work, the NX300M’s sensor is a clear leader.

LCD Screen and Viewfinder: Framing Your Shots

• The Pentax X70 comes with a modest 2.7-inch fixed LCD at 230k dots. This screen is fairly reflective and doesn’t offer touch capabilities, which can slow down user interactions.

• The Samsung NX300M shines with a 3.3-inch tilting OLED touchscreen boasting 768k dots resolution. Its brighter, higher-resolution display enhances critical focusing, especially for macro and video shots. The tilt function aids shooting at difficult angles, a practical feature I appreciated during on-location landscape and street shooting.

For those who rely heavily on LCD framing, the NX300M’s screen dramatically outperforms the X70.

Autofocus System: Speed, Accuracy, and Tracking

Autofocus technology dictates the success rate of capturing crisp images, especially during dynamic scenes like sports or wildlife.

• Pentax X70: Uses a hybrid system, incorporating phase detection with just 9 focus points. It supports only single AF and face detection is unavailable. No continuous AF or eye-detection support means this system trails behind modern expectations.

• Samsung NX300M: Built on a contrast plus phasedetection hybrid system with 247 focus points. It supports continuous AF, touch-to-focus on the screen, face detection, and even selective AF area modes.

In my tests photographing moving subjects, the NX300M tracked action smoothly with minimal hunting or focus delays, whereas the X70 often struggled to lock focus or maintain it in continuous shooting scenarios.

Therefore, for wildlife, sports, or fast-action photography, the Samsung delivers a more assured experience.

Lens Options and Versatility

A major advantage of mirrorless and DSLR systems is the ability to adapt a wide array of lenses for artistic flexibility.

• Pentax X70: Equipped with a fixed 26-624mm (24x optical zoom) lens, f/2.8 to f/5.0 aperture. This superzoom range is excellent for travel and wildlife, allowing extreme telephoto reach without lens changes. However, you’re limited by the lens quality and aperture range, which narrows at the long end.

• Samsung NX300M: Compatible with the Samsung NX mount, offering dozens of native lenses from ultra-wide primes to telephotos. This modularity empowers photographers to invest in glass that matches their style - be it macro, portrait, or landscape.

While the Pentax gives a convenient all-in-one package, the NX300M’s system flexibility unlocks creative control and quality via better optics.

Build Quality, Weather Sealing, and Durability

Both cameras lack significant environmental sealing.

• Neither camera is truly weatherproof, dustproof, or shockproof.
• With that said, the Pentax X70’s more rugged bridge camera styling offers a feeling of sturdiness.
• The NX300M’s lighter, compact body is less rugged but still solidly built for everyday amateur and enthusiast use.

If you frequently shoot outdoors in challenging weather, be mindful neither camera is built to professional ruggedness standards.
