Canon SX150 IS vs Canon SX620 HS: A Hands-On Comparison for Serious Enthusiasts

Choosing between two small sensor superzoom cameras that are a few years apart - Canon’s PowerShot SX150 IS from 2012 and the newer SX620 HS released in 2016 - may sound like a no-brainer at first. After all, newer usually means better, right? But as someone who's extensively tested compact cameras across dozens of real-world scenarios, I can assure you it's never that simple. Let’s pull back the curtain on these two models to see where each shines - and where they fall short - for various types of photography and use cases.

If you're scratching your head about which superzoom to invest in for your photography adventures, this detailed comparison is built on personal hands-on experience, technical nuances, and practical workflow insights. Expect deep dives into sensor tech, autofocus, video capabilities, ergonomics, and more - all filtered through the lens of hands-on use over hundreds of shoots.

Size and Handling: How Compact is Compact?

Starting with the basics: physical size and ergonomics really shape the daily experience of shooting. While both cameras aim for pocketable superzoom appeal, their dimensions significantly impact handling, especially for prolonged use.

The SX150 IS measures 113 x 73 x 46 mm and weighs about 306 grams (using 2 AA batteries), making it a bit chunkier and heavier than the SX620 HS, which is 97 x 57 x 28 mm and weighs just 182 grams - thanks to a built-in rechargeable battery pack.

Having shot with both, I can tell you the SX620 feels modern and sleek in the hand - a clear win for portability enthusiasts or street photographers who value discretion and fast grab-and-go setups. The SX150 IS, with its larger grip and beefier body, offers a bit more stability but at the cost of bulk.

Top marks to the SX620 here, especially for travel or casual day trips where every gram in your pocket counts. The SX150 IS does have a firmer hold, but might tire your hand in long shooting sessions.

Looking Down (and Around): Design and Control Layout

True control aficionados will appreciate the difference in user interface. Buttons, dials, and menu layouts shape how fast - and thus how successfully - you can capture fleeting moments.

Both cameras feature fixed 3-inch LCDs, but the SX150 IS sports a low-res screen at 230k dots, while the SX620 HS boasts a sharper 922k dot display, which makes composing and reviewing images far more pleasant.

Before diving into LCD quality, let’s peek at their topside:

The SX150 IS (left) offers dedicated mode dials with manual exposure options - shutter priority, aperture priority, plus exposure compensation - which is a rarity in this class and necessary for those who want some creative depth. The SX620 HS (right), while sleeker, omits these manual modes for the most part, leaning more toward automatic shooting.

For photographers craving full manual control (a bit unusual for compact superzooms, but vital for learning or creative flexibility), the SX150 IS asserts a clear advantage. Those prioritizing simplicity and compactness might prefer the SX620's minimalism, though it means less direct control.

Sensor and Image Quality: Old CCD vs. New BSI-CMOS

At the technical heart of any camera is the sensor, determining resolution, noise handling, dynamic range, and - ultimately - the aesthetic quality.

Both cameras share the same sensor size: the popular 1/2.3-inch format measuring 6.17 x 4.55 mm, equating to roughly 28 mm² of light-gathering area. Don’t let the same sensor size fool you: sensor technology evolved significantly between the SX150 IS's older CCD sensor and the SX620 HS's newer BSI-CMOS sensor design - a fast-evolving niche known for improving light sensitivity and speed.

The SX150 IS offers 14 megapixels, while the SX620 HS increments to 20 megapixels - seemingly a considerable jump on paper, but with caveats. Higher pixel count on the same-sized sensor tends to mean smaller individual pixels, which can increase noise, notably in low light.

What’s the real-world impact? Shooting outdoors in good daylight, both cameras produce decent images with respectable sharpness. The SX620 HS benefits from the BSI-CMOS's improved noise performance, kicking in especially at higher ISOs up to 3200 (versus 1600 on the SX150 IS). If you shoot in dim conditions, the SX620 HS displays crisper images with less grainy messiness - a step up.

But for general travel, family snapshots, and well-lit scenes, the advantage narrows - a testament to Canon’s solid imaging pipelines in both models.

Autofocus Systems: Speed, Accuracy, and Flexibility

Autofocus can make or break shots of anything dynamic - wildlife, sports, or on-the-fly street scenes. The SX150 and SX620 have AF systems that reflect their eras.

The older SX150 IS relies on contrast-detection autofocus alone, with a single focus point and basic face detection. It supports center-weighted AF and a modest ability to track faces in live view, but no continuous AF tracking for moving subjects.

In contrast, the SX620 HS steps up with nine focus points, including center and multiple areas, plus continuous autofocus modes and more sophisticated face detection - although phase-detection AF is absent in both (an expected limitation at this price and sensor class).

This translates into real world advantages for the SX620 HS in moderately fast-moving situations - sports or kids running about - where it can better keep subjects sharp during bursts of shooting. Speaking of bursts...

Burst Shooting and Buffering: Catching the Action

While superzoomers aren’t exactly race cars in frame rate, their ability to capture sequential images can matter a lot depending on your subject.

• SX150 IS tops out at a sluggish 1 fps continuous shooting.
• SX620 HS pushes that up to 2.5 fps.

Neither will rival dedicated sports cameras or DSLRs, but the SX620 HS's more responsive burst mode and superior focusing will give it a fair edge in tracking and capturing decisive moments - like an impromptu performance or street action.

Video Capabilities: From Snippets to Showstoppers?

If video is on your radar, the SX150’s max video resolution is 720p HD at 30 fps, while the SX620 HS upgrades to 1080p Full HD at 30p, a noticeable boost in quality and detail.

For casual vlogging or family highlights, the SX620 delivers more cinematic footage. Audio is mono on both, and neither supports external mics, so if sound fidelity or advanced video features like 4K are mandatory, neither is your go-to.

Still, optical image stabilization on both smooths handheld footage somewhat, with the SX620’s newer processing offering cleaner results.

Portability and Battery Life: Staying Powered on the Go

Compact cameras should be travel-friendly, and battery life is a serious factor in those multi-hour excursions.

The SX150 IS, running on 2 AA batteries, is both a blessing and a curse: you can grab spares anywhere, but at only about 130 shots per charge, you burn through juice faster than on a DSLR. I often found myself replacing AAs mid-shoot during winter hikes - annoying but manageable.

The SX620 HS employs a proprietary rechargeable lithium-ion battery with a longer life of 295 shots, more than double the SX150's. No AA swapping required, but you must charge or carry a spare pack.

If you’re backpacking or traveling light, the SX620’s battery endurance and smaller size are significant wins, though you’ll miss AA convenience.

The LCD Screen and User Interface: Seeing is Believing

Returning to the LCD, the quality difference affects framing, especially in bright daylight.

The SX620 HS’s brighter, higher-resolution screen makes composing more accurate and reviewing shots a treat. The SX150 IS's lower-res screen can appear dim or grainy outdoors, occasionally making manual focusing tricky - a dealbreaker for macro or landscape obsessives wanting pixel-peep accuracy in the field.

Lens and Zoom: Who’s Got the Reach?

Both cameras come with fixed superzoom lenses with focal length multiplies of 5.8x sensor crop factors.

• SX150 IS covers 28-336 mm (12x zoom) with aperture range from f/3.4 to f/5.6.
• SX620 HS extends to an impressive 25-625 mm (25x zoom) but with a somewhat narrower aperture of f/3.2 to f/6.6.

That means the newer SX620 HS doubles the telephoto reach - a killer feature for wildlife, sports, or distant storytelling.

Of course, the trade-off is sharper images become challenging at the far end unless you nail stabilization. Both cameras have optical image stabilization, which helps, but small sensors and superzoom reach often come with softness near the max zoom.

Weather and Durability: Can They Take a Beating?

Neither camera is weather sealed or ruggedized.

• No dust, splash, shock, or freeze proofing.
• Both compact and lightweight but fragile compared to adventure cameras.

For casual use in dry conditions, fine; for outdoor photographers who brave the elements, you’ll want to add weather protection or consider more robust models.
