Condition
Second-hand product inspected by Camera Market. Includes standard 6-month warranty and 24-48h shipping from Barcelona.
What condition is the camera in?
Every camera that leaves Camera Market goes through a 28-point inspection protocol: shutter condition, autofocus accuracy, sensor integrity, seal tightness, electronic viewfinder calibration, original battery health, and eight further tests on connectivity and firmware.
The specific cosmetic condition (marks, scratches, signs of use) is documented in the actual photographs and in the technical table on the product page. We do not use catalogue images.
What is included in the purchase?
You receive the Phase One Digital Back 2900mAh Battery body with its original NP-FZ100 battery, BC-QZ1 charger, PHASE ONE shoulder strap, original box and printed manual. The 28-point inspection and the 6-month warranty are included in the price.
SD card not included. If you need additional accessories, browse our accessory selection.
What warranty does it have?
All cameras include 6 months of free warranty covering functional defects and technical failures.
You can extend the coverage from the warranty section on this same page:
- 12 months for CHF 6.50 · single payment
- 24 months for CHF 7.85 · single payment · recommended
We also offer 14-day returns with no questions asked. If you are not satisfied, full refund.
How long does shipping take?
Standard shipping to the EU in 4–5 business days with tracking number. For mainland Spain, express 24–48 h option available at checkout.
Technical packaging with custom-cut foam and tamper-evident seals. Transit insurance included.
Is it suitable for beginners?
Yes, without reservation. It has full automatic modes and eye-detection autofocus that works practically by itself, so you can start taking professional photos from day one.
When you grow, the manual controls and customisation curve are exactly what you would expect from a professional body. It is a camera you can learn with for years.
Why buy refurbished?
For three honest reasons: price (between 20 and 40% below new on high-end models), sustainability (keeping a body in circulation avoids manufacturing a new one and all its waste), and transparency: every unit has its own serial number, visible shutter count and inspection date.
Market depreciation does not affect optical or electronic performance. A Phase One Digital Back 2900mAh Battery with 12,000 shots takes exactly the same photos as one with 0.
