DxOMark Camera, Lens & Sensor Score Scraper

Extract objective lab-bench scores for cameras, lenses, and sensors from DxOMark — the world's leading independent image quality measurement authority since 2008.

What this actor does

This actor scrapes scored products from DxOMark, discovering them via the site's sitemap (3,500+ products). For each product it fetches:

  • The test/review page to get the overall DxOMark score, protocol type, and review date
  • The product page to get the brand and full set of sub-scores

Camera sensors — sub-scores extracted:

  • Portrait (Color Depth, in bits)
  • Landscape (Dynamic Range, in EV)
  • Sports (Low-Light ISO)

Lenses — sub-scores extracted:

  • Sharpness (P-Mpix)
  • Transmission (TStop)
  • Distortion (%)
  • Vignetting (EV)
  • Chromatic Aberration (µm)
  • Tested-on camera body

Input configuration

Parameter Type Required Description
maxItems integer Yes Maximum number of products to scrape
startUrls array No Specific DxOMark test/review page URLs to scrape. Leave empty to discover all products via sitemap.

Scrape specific products

To scrape specific products, provide their DxOMark test/review page URLs:

{
  "maxItems": 10,
  "startUrls": [
    { "url": "https://www.dxomark.com/sony-a9-iii-sensor-test/" },
    { "url": "https://www.dxomark.com/sigma-90mm-f2-8-dg-dn-for-sony-lens-test/" }

Discover and scrape all products (sitemap crawl)

Leave startUrls empty to walk the DxOMark sitemap and discover all scored products:

{
  "maxItems": 500
}

Use cases

  • Gear recommendation tools — build recommendation engines using objective sensor scores
  • Affiliate content sites — programmatically enrich product pages with lab-measured scores
  • Price-intelligence platforms — correlate DxOMark scores with market pricing
  • ML training datasets — build computer vision and image quality models with ground-truth measurements
  • Camera comparison apps — power comparison tools with the same data DxOMark uses

Notes

  • No proxy required — DxOMark serves plain HTML with no anti-bot challenges
  • launch_price_usd and rank_in_category are loaded via JavaScript on the product page and are not available in the static HTML; both fields output null
  • Smartphone camera tests are filtered out; only camera sensors (-sensor-test/) and lenses (-lens-test/, -lens-review/) are included
  • The sub_scores field is a JSON-encoded string; parse it with JSON.parse() in your downstream code
