Lens rental vs buy is a financial decision based on how often you'll use the lens. The break-even number of uses is simple: purchase price ÷ rental cost per day. Below that number, renting saves money. Above it, buying does. Factor in lens depreciation to see your true net cost to own.

Analysis
How to Decide Between Renting and Buying a Camera Lens
The rent-or-buy decision comes down to one number: how many times will you use this lens? Divide the purchase price by the daily rental cost and you have your break-even point. A $3,000 lens at $100/day breaks even at 30 uses. If you'll use it 50+ times a year, buy. If you'll use it 5–10 times, rent.
When to Always Rent
Always rent for specialty lenses you'll use on a single project: super-telephoto lenses for a one-time sporting event, tilt-shift lenses for an architectural shoot, or cinema lenses for a video project. A Canon 400mm f/2.8 costs $12,000 to buy — if you're shooting one wildlife assignment, renting at $300/day makes obvious financial sense. Renting also lets you test lenses before committing to a purchase.
Improving the Buy-Side Math
Buying used significantly reduces your break-even point. A used 70-200mm f/2.8 at $1,800 vs. $80/day rental breaks even at 22 uses instead of 35. Factor in resale value: quality lenses depreciate slowly. If you buy for $1,800 and sell for $1,400 after 2 years, your net cost was $400 — less than 5 rental days. Buying makes sense when you shoot regularly enough to amortize the cost over many uses.
FAQ
Is this calculator free?
Yes, completely free with no signup required.
When should I rent instead of buy a lens?
Rent when you need a lens for a one-off project or to test it before buying. If a lens costs $3,000 to buy and $80/day to rent, and you'll use it fewer than 15 times per year, renting costs less. This calculator shows your exact break-even point based on your usage frequency.
How do I find lens rental prices?
LensRentals.com and BorrowLenses.com are the largest US lens rental services. Typical prices: 50mm primes $20–35/day, 70-200mm f/2.8 $60–100/day, super-telephoto 400mm f/2.8 $150–300/day. Local camera shops often rent at lower prices but with less selection. Weekend (3-day) rates are typically 1.5–2x the daily rate.
Does renting save money on expensive gear?
Yes, for specialty lenses you use occasionally. A Canon 400mm f/2.8L costs $12,000 new. At $250/day rental, buying only pays off if you use it 48+ times per year. For most hobbyists and semi-pros doing occasional sports or wildlife, renting expensive telephoto lenses makes strong financial sense.
What about lens depreciation?
Lens depreciation is much slower than camera body depreciation. Quality lenses from Canon, Nikon, Sony, and Zeiss hold 50–70% of their value after 5 years if well-maintained. This makes buying more attractive than it appears — your net cost over 5 years is only 30–50% of the purchase price if you resell. This calculator uses a simple break-even model; for long-term ROI include resale value.
Should I buy used to improve the rental vs buy calculation?
Buying used significantly improves the buy-side math. A 70-200mm f/2.8 that costs $2,800 new often sells used for $1,600–2,000. Buying used at $1,800 vs. renting at $80/day breaks even in just 22 uses instead of 35. Used lenses from reputable dealers (KEH, B&H Used, Adorama Used) with inspection grades are usually reliable.
