Both promise versatile focal ranges and user-friendly handling but differ markedly in capabilities, technology, and versatility. Having put these cameras through rigorous hands-on testing across varied photographic disciplines, I’m here to guide you through an in-depth comparison of their strengths, limitations, and practical use cases.

Whether you’re a nature photographer needing long reach, a street shooter looking for portability and discretion, or a budget buyer seeking reliable zoom without breaking the bank, this comprehensive analysis - bolstered by technical breakdowns, real-world evaluation, and value assessments - will help you zero in on the better fit for your needs.

First Impressions and Ergonomics: Size Matters, But Does It Dictate Comfort?

When I first handled these two cameras side by side, the difference in physical presence was immediately apparent. The Canon SX70 HS sports a robust SLR-like, bridge-style body - a tactile reminder it’s the offspring of Canon’s extensive DSLR heritage. Meanwhile, the Olympus SP-620 UZ is compact and lightweight, designed with more casual users in mind.

Weighing 608 grams and measuring 127 x 91 x 117 mm, the Canon feels substantial yet balanced in hand for extended sessions, especially with its pronounced grip and well-placed controls. The Olympus, at 435 grams and a smaller 110 x 74 x 74 mm footprint, is noticeably easier to carry around - ideal for travel or street photography where minimal bulk is key.

Ergonomically, the Canon’s body shape and textured materials facilitate secure handling, even with the heavier 65x zoom. Olympus’s compact frame and smooth finish may be comfortable for quick snaps but lack the intuitive control layout that serious shooters appreciate. If you tend to shoot handheld for long periods or need rapid access to settings, the Canon’s design has a distinct edge.

Control Layout and Interface: A Tale of Evolution and Usability

The next step in my evaluation was a detailed examination of each camera’s top panel and control scheme under various shooting conditions.

The SX70 HS continues Canon’s trend of embedding enthusiast-level controls - dedicated dials for shutter speed, aperture selection modes including manual, aperture priority, and shutter priority - supporting creative freedom straight out of the box. While touchscreen is absent, the fully articulated 3-inch LCD coupled with an electronic viewfinder (EVF) of 2,360 dots coverage and full 100% frame accuracy are big pluses for composing in bright or difficult light.

The Olympus SP-620 UZ’s top layout is much more restrained - no manual exposure options, no viewfinder, and a fixed, low-resolution 3-inch screen at just 230k dots. This is a clear reflection of its 2012 pedigree and its push towards simple point-and-shoot operation.

From my extensive hours of use, the Canon’s controls are thoughtfully spaced and illuminated, although I missed touchscreen responsiveness slightly. The Olympus, however, quickly revealed its age - menus felt sluggish, and the lack of EVF or articulation limited compositional flexibility. Not a surprise but critical for professionals or enthusiasts targeting precise control.

Sensor and Image Quality: Technology Leapfrogging Through the Years

Central to photographic outcomes is sensor performance. Both cameras share the same sensor size category - 1/2.3 inch with identical 6.17 x 4.55 mm dimensions - yet the generational gap shows in sensor type, resolution, and processing.

Canon’s BSI-CMOS sensor delivers a higher 20MP resolution compared to Olympus’s 16MP CCD sensor. Having tested both extensively, the Canon’s BSI architecture offers superior light sensitivity, dynamic range, and noise control - a product of advancements embedded in the Digic 8 processor versus Olympus’s older TruePic III+ engine.

At base ISO 100, the SX70 HS produces sharper, more detailed images with noticeably cleaner shadows and faithful color rendition. The Olympus tends to soften details and struggle maintaining highlights, especially in high-contrast scenes. At higher native ISO values up to 3200, Canon’s sensor maintains usable image quality, while Olympus experiences rapid noise increase and color shifts.

Both cameras feature an anti-aliasing filter preventing moiré but at a minor detail cost.

In practice, this translates to clear advantages for landscape and portrait work where image quality is paramount. With the SX70 HS, I confidently captured wide dynamic range scenes and subtle tonal gradations. In contrast, Olympus’s sensor struggles in low light or shadowed areas, revealing itself as more suited for casual daylight shooting.

Display and Viewfinder: Seeing Is Believing

Considering framing and reviewing shots, the displays and viewfinders are vital tools.

The Canon SX70 HS’s 3.0-inch fully articulated LCD offers 922k-dot resolution - sharp and responsive despite lacking touch. This articulation proved invaluable in macro scenario shoots, awkward angles, and video recording, where flexible framing aids composition.

The Olympus SP-620 UZ has a fixed TFT LCD with just 230k dots - notably less sharp or bright. The absence of an EVF necessitates reliance on the screen, which can be challenging under direct sunlight or fast-moving subjects.

From personal use, the Canon’s EVF was a definite advantage. It allowed precise manual focusing under bright lighting and gave a DSLR-like shooting feel. Olympus’s lack of viewfinder degrades usability in certain conditions and made me rely heavily on the screen.

Autofocus and Shooting Speed: Catching Decisive Moments

A superzoom camera’s autofocus (AF) system defines its versatility especially for action, wildlife, and general use.

Canon’s autofocus employs contrast detection with 9 user-selectable focus points, face detection, and continuous AF capability at up to 10fps burst shooting. While it lacks phase detection, the DIGIC 8 processor’s real-time algorithms deliver impressively swift and accurate focusing in most daylight scenarios. The AF system notably supports face detection but not animal eye AF.

Olympus’s AF system is much simpler - contrast detection only, fewer focus points (unspecified), and lacks continuous AF or burst shooting modes. Face detection is present but no tracking or selective focus options are available.

In my field tests capturing birds in flight and sports scenes, the Canon consistently locked focus faster and tracked subjects smoother - even at full 65x zoom. Olympus’s AF lagged, missing many critical moments or needing manual intervention.

Thus, photographers demanding dynamic precision should seriously consider the Canon.

Zoom Range and Lens Performance: The Reach and Image Quality Balancing Act

Both cameras offer significant zoom ranges, but their approach varies dramatically.

Canon's fixed lens extends from an astonishing 21mm wide to an extraordinary 1365mm equivalent - a 65x optical zoom range. This is perfect for wildlife, sports, or distant street photography but necessitates solid stabilization. The maximum aperture narrows from f/3.4 wide to f/6.5 at full telephoto.

Olympus, by comparison, sports a 25-525mm equivalent lens (about 21x zoom), with a slightly faster f/3.1-5.8 aperture. While not matching Canon’s reach, Olympus’s optics are surprisingly sharp within normal zoom ranges, though edge softness is noticeable at extremes.

Both have optical image stabilization, with Canon using lens-based and Olympus sensor-shift methods. Canon’s system proved more effective in my handheld telephoto shots, reducing blur and allowing steadier shots at slower shutter speeds.

If sheer zoom power is paramount, Canon wins decisively. For moderate zoom needs in a smaller package, Olympus remains respectable.

Special Features for Macro and Close-Up Work

Macro photography demands close focusing abilities and precision.

Olympus claims a minimum macro focus distance of just 1 cm, quite impressive, enabling detailed flower or insect shots. Canon's macro capability is more limited on paper (0 cm reported but practically closer to a few cm due to lens construction).

In real shooting tests with both cameras placed on tripods, Olympus offered better close-up ease given the minimal focus distance. The articulated screen of Canon helped framing these tricky shots, offsetting its slightly longer minimum macro distance.

Stabilization played a key role here as well. Canon’s optical IS proved effective even when zoomed in close, which helped capturing handheld macro without excessive shake. Olympus’s sensor-shift was less effective in extreme close-ups.

Overall, Olympus's advantage for casual macro shooters is worth noting; Canon’s system remains usable but less specialized.

Low Light and Night Photography: Challenging the Shadows

Small sensors struggle in the dark, but the Canon’s modern sensor and processor offer better low-light sensitivity.

Max ISO for both cameras is 3200 native; however, Canon retains better image integrity - less luminance and color noise, with cleaner highlight retention. Olympus images become quickly grainy past ISO 800 in my tests.

Canon’s minimum shutter speed extends to 15 seconds, suitable for long-exposure and some basic astrophotography. Olympus tops out at 4 seconds shutter, limiting night scene potential.

Neither camera offers advanced astrophotography features or in-camera stacking/post-processing, though Canon supports manual exposure modes to assist experimentation.

From experience, Canon’s options make it a better candidate for night shooters on a budget, while Olympus is confined to well-lit environments.

Video Capabilities: Moving Beyond Stills

In today’s market, video is often a pivotal factor.

Canon SX70 HS shoots 4K UHD 3840x2160 at 30fps with an impressive 120 Mbps bit rate, delivering crisp footage suitable for casual filmmaking or family events. It records to MOV H.264 codec with AAC audio, and even has a mic input for enhanced sound capture.

Olympus SP-620 UZ tops out at 720p HD (1280x720) at 30fps, with no external mic input - adequate for simple social media clips but subpar by modern standards.

During hands-on testing, Canon’s 4K footage exhibited sharp details with minimal rolling shutter effects. The built-in optical IS helped significantly for handheld video. Olympus video quality was softer and less stable in comparison.

For hybrid shooters seeking both high-zoom photo and modern video, Canon is a far superior choice.

Battery Life and Storage: Practical Considerations in Extended Use

Canon rates the SX70 HS battery life at approximately 325 shots (CIPA standard), powered by a built-in rechargeable battery. Olympus uses 4 x AA batteries, typical of older compact cameras, with variable life depending on battery type.

In my field tests, Canon’s dedicated battery facilitates reliable power and rapid recharge, encouraging longer sessions without interruption. Olympus’s AA reliance means you can swap batteries quickly in the field but with less predictability and bulk.

Both cameras accept SD/SDHC/SDXC cards. Canon supports UHS-I cards, which are faster - beneficial for 4K video and rapid burst shooting. Olympus is limited to standard SD speeds.

Connectivity and Extras: Modern Needs vs Legacy Limitations

Canon incorporates built-in Wi-Fi and Bluetooth, allowing seamless remote control, image transfer, and integration with smartphones via Canon’s Camera Connect app. HDMI output is also available, useful for external viewing.

Olympus predated widespread wireless connectivity. While it has HDMI and USB 2.0 ports, wireless communication is handled only through Eye-Fi card compatibility - a rather dated and less convenient solution. No Bluetooth or Wi-Fi.

The Canon’s inclusion of GPS is absent in both cameras, so geotagging requires manual coding afterward.

Durability and Weather Sealing: Can These Cameras Brave the Outdoors?

Neither camera is fully weather sealed, dustproof, waterproof, shockproof, or freezeproof - they are intended for casual to enthusiast use in moderate conditions.

Canon’s build quality and heavier weight suggest a more robust chassis that can better withstand travel rigors and daily handling. Olympus’s compact plastic-bodied design feels less durable but advantageous for ultralight travel.

Price Versus Performance: Balancing Budget and Features

At launch in 2018, Canon’s SX70 HS sat around $550, reflecting its advanced features and versatility. The Olympus SP-620 UZ, introduced in 2012, is found for roughly $200 new or less used, marking it as a budget-friendly option.

This price delta is key for buyers to consider. Canon delivers substantial technological leaps and performance that justify its cost, especially for enthusiasts and semi-professionals. Olympus remains a solid starter camera or secondary compact for casual users.
