Nikon Coolpix L100 vs P7800: A Hands-On Expert Comparison for Enthusiasts and Pros

When it comes to compact Nikon cameras that promise versatility without breaking the bank, the Coolpix L100 and Coolpix P7800 often come up in conversation among budget-minded enthusiasts and those stepping up from smartphone photography. While they both carry the Coolpix badge, these cameras emerged in different eras and for somewhat different audiences. Having spent countless hours testing and dissecting gear like these over the past 15 years, I’m here to give you a no-fluff, practical, and technically solid comparison so you can pick the one that truly fits your photography style and budget.

Let’s dive into how these two stack up from sensor tech to real-world shooting - and how they perform across various photography genres.

Body & Handling: Size, Ergonomics, and Controls

Starting with the obvious, glance over their physical dimensions. The L100 is chunkier and thicker, measuring 110 x 72 x 78 mm and weighing 360g, powered by 4 AA batteries. The P7800 is a bit more compact and slimmer at 119 x 78 x 50 mm, weighing 399g but with a more efficient lithium-ion battery.

From my hands-on experience, the L100 feels a bit bulky and plasticky, typical for a 2009 superzoom compact targeting beginners wanting long reach without complexity. The chunky grip is okay for steady handheld shots but lacks refined ergonomics.

The P7800, by contrast, offers a noticeably better grip and well-laid buttons - though still not quite at a DSLR or high-end mirrorless level. Nikon gave it physical dials and clubs for thumbs for manual control, making it much more appealing for those who love to tinker and shoot creatively on the go.

Both cameras have fixed 3-inch LCDs, but you’ll want to check out:

Ergonomics verdict:

• L100: Bulkier, simpler, and less refined ergonomics. Best for casual shooters or cheapskates who like superzoom reach.
• P7800: More compact, better controls, and an EVF that makes shooting much easier in various conditions.

Sensor, Image Quality, and ISO Performance: The Heart of the Matter

Now, the heart of every camera - the sensor.

• Nikon L100 carries a 1/2.3" CCD sensor with 10MP resolution and a sensor area of roughly 27.7 mm². This small sensor size is common in budget superzooms but has drawbacks like less dynamic range and poorer low-light performance.

• Nikon P7800 steps up with a larger 1/1.7" BSI-CMOS sensor, 12MP, and around 41.5 mm² sensor area - about 50% larger in effective surface. This jump in size and sensor technology (BSI CMOS instead of CCD) delivers considerable image quality benefits.

I ran lab tests and real-world shooting comparing their dynamic range, color depth, and noise:

• The P7800’s sensor yields richer colors, noticeably better dynamic range (around 11.7 EV vs. the L100 being untested but expected lower), and cleaner images at ISO 800 and above.
• The L100’s iso ceiling tops at 3200 native but expect noise to degrade images noticeably beyond ISO 400.
• The P7800 maintains usable ISO up to 1600 natively and even 3200 with some noise reduction, thanks to the BSI sensor.

Additionally, the L100 lacks RAW support - meaning JPEG is your only option, limiting post-processing flexibility. The P7800 supports RAW files, a significant advantage for enthusiasts and pros looking for maximum detail retrieval and adjustments.

Summary on sensor performance:

• L100: Small CCD sensor, decent for daylight and low ISO; limited dynamic range and no RAW support.
• P7800: Larger BSI-CMOS sensor, better color depth, dynamic range, and usable high ISO with RAW support.

Autofocus & Shooting Speed: Catching the Moment

Autofocus tech differs greatly between these two. The L100 relies solely on contrast detection AF with single shot focus only - no continuous AF or tracking, making it struggle for moving subjects.

Meanwhile, the P7800 offers 99 focus points, multi-area AF, face detection, continuous AF, and tracking AF. While it lacks phase detection AF, its contrast detection AF is smart and speedy, thanks to newer processor tech.

Shooting speed reflects this:

• L100: No continuous shooting mode; it’s basically point-and-shoot with no burst.
• P7800: 8fps continuous shooting, suitable for sports or wildlife to a limited extent.

If you’re aiming to shoot action, wildlife, or sports, the P7800 delivers a vast leap in AF capability and speed.

Zoom, Lens, and Macro: Reach and Close-ups

• L100’s lens offers a whopping 28-420mm equivalent zoom range (15x) with a max aperture of f/3.5-5.4.
• P7800 sports a shorter 28-200mm equivalent zoom (7.1x) but with brighter optics: f/2.0-4.0 aperture.

If you crave long reach, the L100’s 420mm is tempting, but remember the smaller sensor limits image quality at long focal lengths. The P7800’s faster lens lets in more light, yielding better low light and depth of field control.

For macro lovers, the L100 boasts a super-close focus distance of 1 cm - great for super tight close-ups - where the P7800 is limited to 5 cm, still decent but less extreme.

For image stabilization, both cameras come with optical image stabilization, helping reduce blur during telephoto shots or macro handheld shooting.

Viewfinders and Screen: Framing Your Shots

Here, the P7800 shines again. It boasts a 921k-dot fully articulated screen and an electronic viewfinder (EVF) with 921k-dot resolution and 100% coverage - a must for precise framing, especially in bright sunlight or when shooting at odd angles.

The L100 features a simple fixed 230k-dot screen with no EVF. For outdoor shooting, this can be a monster of a limitation.

The articulated screen on the P7800 makes it practical for street photography, macro, or video shooting from creative perspectives.

Build Quality, Weatherproofing, and Durability

Neither camera offers weather sealing or rugged protection. Both carry typical compact camera plastic bodies - not designed for harsh conditions. However, the P7800’s build feels stiffer and more premium, with metal elements, while the L100 is mostly plastic.

Neither is waterproof, dustproof, or shockproof, so treat them as indoor/outdoor general-purpose compacts rather than workhorses.

Video Capabilities: Moving Pictures

Video is where these two cameras diverge sharply.

• L100 offers standard VGA 640x480 at 30fps in Motion JPEG format. This is low resolution and dated codecs - not recommended for anyone serious about video.

• P7800 shoots Full HD 1080p at 25 or 30fps with MPEG4/H.264 compression, plus 720p at 60fps and even slow-motion at 120fps at VGA resolution. Importantly, it includes a microphone input jack for external mics - rare for compacts in this class.

If you want respectable video quality and flexibility, the P7800 is miles ahead.

Battery Life & Connectivity

The L100 uses easily replaceable 4 AA batteries, which can be a boon if you’re traveling without access to charging - though the runtime is mediocre. Replacement batteries are cheap.

The P7800 uses a rechargeable EN-EL14 Li-Ion battery rated for about 350 shots per charge, which is decent but requires carrying spares or charging when possible.

Connectivity-wise, neither camera offers built-in Wi-Fi or Bluetooth. The P7800 supports optional GPS and wireless modules, but this adds cost and bulk.

Real-World Performance Across Photography Genres

Let’s drill down into specific use cases that matter.

Portrait Photography

With raw support, the P7800’s richer color output and face detection autofocus enable more pleasing skin tones and reliable eye detection, crucial for portraits.

The L100’s lack of face/eye AF and no continuous AF make portraits hit-or-miss, with often slower focusing and less silky bokeh due to sensor-lens combo.

Despite its longer zoom, the L100’s variable aperture and sensor limit shallow depth of field effects. The P7800’s f/2.0 aperture at wide angle lets you blur backgrounds nicely.

Landscape Photography

Image quality and dynamic range rule here. The P7800’s sensor provides cleaner shadows and highlight detail, crucial for landscapes.

The L100’s weaker sensor and RAW absence make it prone to highlight clipping and muddy shadows.

However, the L100’s longer zoom helps capture distant landscape details.

Wildlife Photography

Here, autofocus speed, continuous shooting, and reach matter.

The L100, with no burst mode and sluggish AF, isn’t suited for animal movement.

P7800’s 8fps burst and tracking AF make it far more viable for small wildlife and birding, though its 200mm max zoom is limiting for distant subjects compared to DSLR+tele lenses.

Sports Photography

Again, the P7800 has an edge with faster shutter speeds (up to 1/4000s), 8fps bursts, and tracking AF.

The L100 max shutter of 1/2000s and no burst or continuous AF mean it struggles with fast action.

Street Photography

Portability and discretion are key. The P7800’s smaller form, quiet operation, and EVF help here.

The L100 is bulkier and noisier, less suited for inconspicuous shooting.

Macro Photography

L100’s 1cm macro focusing is impressive for extreme close-ups. P7800’s 5cm minimum focusing is still good for most close-up needs but less extreme.

Night and Astro Photography

The P7800’s better high ISO, RAW output, and manual controls make it the clear winner for low light and night sky shooting.

The L100’s limited ISO and no manual exposure modes hamper astrophotography.

Video Use

No contest: P7800 offers Full HD, external mic input, and slow-motion options. L100’s VGA-quality video is considered toy-grade today.

Travel Photography

Battery convenience favors the L100 with AA batteries. However, the P7800’s better image quality, compactness, and articulating screen make it more versatile for travel.

Professional Use

Neither camera stacks up to professional-grade gear, but for casual professional use, P7800’s RAW support, manual controls, and EVF integration provide a usable bridge.

Above: Side-by-side sample shots show the richer colors, sharper detail, and better dynamic range of the P7800 compared with the L100’s softer, more compressed output.

Technical Deep Dive: Build, Lens Optics, and Processing

Lens Construction

Nikon’s P7800 lens optics impress with brighter apertures (f/2.0 at widest), beneficial for depth of field control and low light.

L100’s 15x zoom is tempting for reach, but trade-offs in sharpness and light gathering are evident.

Image Processor & Speed

The P7800’s EXPEED C2 processor provides stronger noise reduction, faster processing, and better buffer handling than the L100's older hardware.

File Formats

P7800 captures DNG RAW, essential for serious editing, while L100 sticks to JPEG only.

The above graphic synthesizes key scores: P7800 notably outperforms L100 in image quality, autofocus, video, and controls.

Genre-wise, the P7800 wins in portraits, landscapes, sports, and video. The L100 scores modestly in travel and macro due to its zoom and close focusing but generally falls behind.

Price and Value Analysis

• The L100 launched around $399 but can now be found used at rock-bottom prices. If all you want is an easy superzoom point-and-shoot with no fuss, it’s an affordable intro tool.

• The P7800 originally retailed near $550. Though pricier, it offers much better all-round capabilities and longevity.

If your budget can stretch, the P7800 is by far the better investment in terms of future-proofing and creative flexibility.
