The Canon EOS 5D Mark III is rightfully a legend. Part of Canon’s incredibly popular EOS 5D line that revolutionised filmmaking, the 5D Mark III is a full-frame DSLR that has remained enduringly popular among professionals and enthusiasts alike. But this is a camera from 2012. Can the Canon EOS 5D Mark III really be worth buying in 2026?
I think so – in fact, I think for a lot of advanced hobbyist photographers, this DSLR is the smart play. The reason for this is simple: its price has plummeted on the used market since release. A camera that once would have cost you £2,999 in 2012 money is now available for as little as £369 used. I’d recommend pairing it with a used Canon EF 24-105mm f/4L IS USM lens, a do-it-all zoom that can be bought used for as little as £224. For a total spend of just under £600, you’ve got yourself a professional-level camera setup.
And I do mean professional-level – the EOS 5D Mark III images has been used by countless pros over the years, its images having graced front pages, magazine covers and billboards. Its dual SD card slots enable a professional workflow, its weather-sealed body can stand up to the elements, and its 22MP full-frame sensor produces detailed and dynamic imagery. In terms of balancing price and performance, I think it’s one of the best Canon full-frame cameras to buy second-hand.
Of course, tech has moved on. If we compare the older DSLR to a newer mirrorless camera, pit the Canon 5D Mark II vs the Canon R6 Mark II, we can see some pretty stark differences. The EOS R6 Mark II can shoot at a blistering 40fps, compared to 6fps on the 5D Mark III. It boasts built-in IBIS (in-body image stabilisation) and its autofocus is significantly more sophisticated, with AI-powered automatic subject recognition.
But here’s the thing. Paired with an equivalent lens to our first combination, the RF 24-105mm F4-7.1 IS STM, the Canon EOS R6 Mark II comes to a total cost of £2,549. That’s more than four times the cost of our used combo – and, I have no doubt, is likely beyond the budgets of many hobbyist photographers.
Sure, you don’t get the latest tech. But both cameras use a full-frame imaging sensor to deliver stunning, professional-level quality.
How safe is it to buy used cameras?
You might feel you prefer the safety of buying a new camera right off the shelf. But buying used photo gear is as safe as can be when you use a reputable retailer – any decent photo retailer worth their salt will offer a limited warranty on used gear (at Wex, ours is 12 months) and you shouldn’t buy from anyone who doesn’t.
It’s also an advantage of buying used professional cameras – because pro gear is built to last. The Canon EOS 5D Mark III is a heavy-duty, well-armoured camera that’s capable of taking knocks and bumps and keeping on shooting. And should issues arise, a dedicated repair service such as that offered by Wex’s in-house team will keep it shooting for many years to come.
It’s a close-run thing, but I think the Canon EOS 5D Mark III is the best used professional Canon camera to buy right now – and for many hobbyists, is the best Canon camera to buy, full-stop.
