Economic feasibility of purchasing a carcass with a mileage of 100k+

On the secondary market, full-screen professional cameras (such as Nikon D750, D810, Canon 5D Mark III/IV, Sony A7 III) with mileage from 100,000 to 150,000 frames are **40–60% cheaper** than similar models with mileage up to 20 000 frames.

A natural question arises: is such a discount purchase justified, or will the savings be eaten up by the first visit to service center?

Pros of buying a high mileage camera

• Significant financial discount:You get a top-end full-frame sensor, fast autofocus and metal waterproof body for the price of an amateur crop camera.
• Proven Reliability:If the shutter and mechanics took 100,000 frames without failure, this means that this specimen does not have a hidden manufacturing defect.
• Minimum loss of resale value:Camera purchased for 40,000 rubles with mileage 110k, in a year with a mileage of 125k it will be sold for the same 35,000–40,000 rubles.

Cons and possible risks

1. Risk of unplanned shutter failure:The shutter may fail during critical shooting. (wedding, reportage). A spare carcass will be required.
2. Wear of the mirror mechanism and diaphragm drive:In addition to the shutter itself, production is tested mirror unit springs and aperture drive motor.
3. Loss of presentation:Scuffs, wear of rubber pads, loose mount.

Profitability calculator

Let's calculate the mathematical model using the example of a top-end full-frame SLR camera:

Parameter	Option A (Mileage 15,000)	Option B (Mileage 115,000)
Average price on the used market	85,000 rub.	45,000 rub.
Cost of potential shutter replacement	0 rub. (not required yet)	12,000 – 15,000 rub.
Total costs in case of breakdown	85,000 rub.	57,000 – 60,000 rub. (with fresh shutter!)
Net benefit to the buyer	Base price	Saving RUB 25,000!

Key takeaway: when should you buy?

Buying a camera with over 100,000 frames is **very profitable** if it is a top pro model (Nikon D800/D810/D850, Canon 5D III/IV) with an official resource of 200,000–300,000 frames, and the financial discount exceeds the cost of repair shutter twice.
