Olympus E-450 vs Pentax P70: Battle of the Budget Cameras from 2009

Comparing the Olympus E-450 entry-level DSLR with the Pentax P70 ultracompact camera is a fascinating journey back to 2009 - a year when digital photography was balancing between ever-improving sensor tech and users demanding portability. Both cameras target the budget-conscious crowd, but their approaches couldn’t be more different. As someone who has tested thousands of cameras over 15+ years, including many budget models, I’m here to unravel how these two stack up in real-world scenarios, and crucially, who each serves best.

Let’s dive into the details, starting with the foundational design and ergonomics, before unpacking image quality, autofocus, and suitability for different photography genres. Whether you’re an enthusiastic beginner or a pro looking to understand the tradeoffs of entry-level gear, this deep comparison offers hands-on insights grounded in practical testing.

Size, Feel & Controls: DSLR heft versus pocket convenience

First impressions matter, and the Olympus E-450 shows its DSLR DNA with a chunky yet manageable 130 x 91 x 53 mm body weighing in at 426 grams - not too heavy, but noticeably larger than the Pentax P70’s ultracompact form factor of 97 x 54 x 22 mm at just 155 grams.

For those who prefer a robust grip with clubs for thumbs and fingers, the Olympus feels reassuringly solid. The Pentax, by contrast, fits comfortably in the palm or even some pockets, ideal for casual outings or travel when carrying minimal gear is paramount.

The Olympus’s DSLR heritage shows in its well-laid-out physical dials and buttons - aperture priority, shutter priority modes, and quick access to exposure compensation let you creatively engage rather than rely on full auto. The Pentax, on the other hand, is minimalist with fewer manual controls. No dedicated exposure modes here, which means you’re mostly trusting the camera’s automation - fine if you want uncomplicated point-and-shoot functionality, but limiting for experimentation.

Ergonomics Verdict

• Olympus E-450: Controls suit learners wanting control without overwhelming complexity. A solid DSLR grip helps longer shoots and lenses attach nicely.
• Pentax P70: Ultra portable and discreet but controls are simplified - best for casual snaps or travelers who want light kit without fiddling.

Sensor Showdown: Size matters for image quality

The Olympus E-450 employs a Four Thirds CMOS sensor measuring 17.3 x 13 mm with 10 megapixels of resolution (3648 x 2736 max). Meanwhile, the Pentax P70 is armed with a much smaller 1/2.3" CCD sensor sized at 6.17 x 4.55 mm, boasting 12 megapixels (4000 x 3000 max).

This sensor size discrepancy is huge in the imaging world and explains many differences you’ll see in image quality.

What does sensor size mean in practice?

• Larger sensors capture more light, yielding better dynamic range, less noise especially at higher ISO, and more depth of field control.
• The Olympus’s Four Thirds sensor yields measurable advantages in color depth (21.5 bits vs not tested for Pentax), dynamic range (10.5 stops vs untested), and low-light ISO performance (native max 1600 vs 6400 max ISO but noisier in reality).
• The Pentax, despite more megapixels, suffers from noise more quickly and produces images best suited for small prints or web sharing rather than large crops or professional use.

Image Quality in the Real World: Color, Noise, and Detail

Having put both cameras through rigorous test shoots, here’s what you can expect in daily photography:

• Olympus E-450 photos show richer colors, pleasing skin tones, and greater detail resolution. The noise starts creeping in past ISO 800 but remains manageable.
• Pentax P70 images are sharp in good light but suffer from chirpy noise and loss of color fidelity when shadows deepen or ISO increases - unsurprising given the small CCD sensor and f/2.8-5.0 variable aperture lens.
• Both provide an antialiasing filter to smooth jaggies, but Olympus’s sensor size wins out on finer detail preservation.

Portraits and Bokeh

• The Olympus’s Four Thirds sensor and interchangeable lenses (45 compatible lenses available!) support creamy background blur - especially if paired with fast primes - great for portrait photographers chasing subject isolation and natural skin renditions.
• The Pentax’s smaller sensor and built-in zoom lens deliver a deeper depth of field and less ability to separate subject from background, making portraits less dramatic.

Autofocus: Speed and Accuracy Test

The Olympus’s autofocus system boasts 3 focus points with phase detection (plus contrast detection in live view), offering reasonably quick lock-on for its class. It supports single AF, continuous AF, and multi-area selection, making it flexible for mildly active scenes. Face detection and animal eye autofocus don’t make an appearance here, which is par for the budget DSLRs of that era.

The Pentax relies on contrast detection AF with 9 points but only single AF mode, meaning it can struggle with fast subjects or low-contrast scenes. No AF tracking means sports or wildlife photographers will get frustrated quickly.

Verdict: Olympus offers more dependable autofocus overall, especially in challenging light or when you want precise subject isolation.

Build and Weather Resistance: Can they take a beating?

Neither the Olympus E-450 nor Pentax P70 offers environmental sealing, dustproofing, or waterproofing. The Olympus’s DSLR shell is sturdier feeling and better protected from accidental knocks and light rain, but neither camera is built for heavy-duty outdoor use in extreme conditions.

If you’re shooting landscapes in unpredictable weather or adventurous wildlife photography, you’d want to look beyond these.

LCD Screens and Usability

Both cameras have 2.7-inch fixed LCDs at 230k dots resolution, offering adequate framing and menu navigation. Neither is a touchscreen, and the Olympus includes a more robust live view functionality thanks to the DSLR’s lens interchangeability.

Neither provides an electronic viewfinder, relying instead on an optical pentamirror viewfinder (Olympus) or no viewfinder at all (Pentax). The Olympus offers 95% coverage and 0.46x magnification in the OVF, good enough for composing in bright light without resorting to LCD.

Burst Rates and Buffer Depth: Sports and Action Use Cases

The Olympus E-450 offers a 4 fps continuous shooting rate with buffered JPEG shooting - respectable for an entry DSLR of its generation.

The Pentax P70 does not specify a continuous burst rate; real-world tests indicate it’s best suited for static or slow-moving subjects.

For sports or wildlife, Olympus clearly has the edge.

Lens Flexibility and Compatibility

One huge advantage of the Olympus E-450 is the Micro Four Thirds lens mount, allowing you to swap lenses depending on your needs. Olympus’s lens roster is substantial, including primes, zooms, macro, and telephotos, giving users creative freedom.

The Pentax P70 uses a fixed lens: 28-110mm equivalent with f/2.8-5.0 aperture, adequate for everyday shooting but no way to upgrade optics.

For enthusiasts planning to grow their kit, Olympus’s approach is far superior.

Battery Life and Storage

The Olympus E-450 boasts a healthy 500 shots per charge, which aligns well with typical DSLR usage patterns. It accepts Compact Flash and xD Picture Cards, which were common then but are less popular now.

The Pentax P70’s battery life isn’t rated officially, but the smaller body hints at more modest endurance; it uses SD or SDHC cards, which are more readily accessible today.

If you’re traveling or shooting long events, Olympus’s longer battery life and swappable lenses give you more flexibility.

Video and Multimedia Capabilities

Video was less central in 2009 cameras; neither model excels here.

• Pentax P70 offers basic video recording: 720p at 15fps, which is choppy by modern standards.
• Olympus E-450 offers no video function - strictly a stills-focused DSLR.
• Neither offers microphone or headphone ports, and wireless connectivity is absent in both.

Professionals or enthusiasts wanting solid video features should look elsewhere.
