How We Recommend Lenses
Every recommendation on LensPicks is backed by data. Here is exactly how we evaluate and recommend lenses.
1. Real-Time eBay Price Data
We use the official eBay Browse API to pull live listings every time you search. This means every price, condition, and listing you see is current — not cached data from hours ago. We track 18+ lens categories including Canon RF, Nikon Z, Sony FE, Tamron, Sigma, and more.
2. Price History & Market Averages
Every 6 hours, our automated system re-fetches prices for popular lens searches and records them in our database. Over time, this builds a price history for each lens. When you see a listing, we compare its price to the 30-day market average and show you how good the deal really is. Our deal scoring ranges from 🔥 20%+ below market to above market.
3. Value-Based Curation
We surface lenses that offer the best value at their price point. A lens that is 20% below its 30-day average gets flagged in our Hot Deals section. Lenses consistently priced above market are deprioritized. Our goal is to save you money, not to show you every listing.
4. Editorial Expertise
Our buying guides and articles are researched and written by the LensPicks Editorial Team. We evaluate lenses based on optical performance, build quality, autofocus speed, value retention, and real-world usability. Our recommendations are independent — we do not accept payment or free products from manufacturers.
5. Transparency
Every product link on LensPicks is an affiliate link. If you click and make a purchase on eBay, we may earn a small commission at no extra cost to you. This is how we keep the site free. Our editorial content is never influenced by affiliate commissions. We clearly mark all affiliate links with and sponsored attributes.
