One decision that a lot of improving photographers face when it’s time to buy or upgrade their DSLR or mirrorless camera is whether they should buy a new crop sensor camera or an older, second-hand full frame camera. There are arguments to both sides so let's dig in.

If you’re reading this article, you’re probably already familiar with the differences between full frame and crop sensor cameras. If you’re not, you should check out our full article on the subject, but, in brief, there are two main formats of DSLR and mirrorless cameras: 35mm or full frame and crop sensor or APS-C. Full frame cameras are based off the 35mm film standard while APS-C cameras use a sensor that’s about two-thirds the size. Professional cameras tend to use full frame sensors while consumer and entry-level cameras use crop sensors.

Brand new full-frame cameras, like the Canon 5D Mark IV, cost a few thousand dollars. Even the Canon 6D Mark II starts at $1,600 on Amazon, although its list price is $2,000. Crop sensor models are a lot cheaper. The Canon Rebel T7i is $749 while our sister site’s pick for the best beginner DSLR, the Nikon D3400, is just $400—with an 18-55mm lens.

The thing is, you can buy second-hand full frame cameras for crop sensor money. You can get a good Canon 5D Mark II, one of the most successful professional cameras ever made, for around $600. A Canon 5D Mark III, the camera I use, can be had for less than a grand if it’s a bit beat up or about $1,300 if it’s in good condition. This means that, especially for improving photographers, there’s a choice to be made.

Consumer and Professional Cameras

As I mentioned above, full frame sensors get used in professional cameras while crop sensors get used in consumer cameras. The differences between the two are worth highlighting.

  • Build quality: Professional cameras are designed to take a beating. They’re made out of aluminum alloys, often have weather sealing, and generally work anywhere. Consumer cameras are meant for vacations and family photos. They’re made from plastic, and a proper rainstorm might not be good for them.
  • Better controls: Consumer cameras have lots of automatic modes, so you don’t really have to think about taking pictures. Professional cameras give you a lot more manual controls. Expect to see things like dedicated shutter speed and aperture dials, custom presets, and a more ergonomic layout.
  • Multiple card slots: Multiple storage card slots let you shoot to two cards at once, so all your photos are backed up. Consumer cameras only have one.
  • Different lens mounts: Consumer and professional cameras have different lens mounts. In general, full frame lenses will work on crop sensor cameras while the reverse is not true. If you have a lot of DX or EF-S lenses, this might be a dealbreaker.
  • Better autofocus: Professional bodies—or at least recent ones—tend to have better autofocus with more points than consumer bodies.

And we haven’t even talked about image quality yet!

Although, that’s where things get a bit trickier and really, it depends on what two cameras you’re comparing. For example, a 5D III has a 22.3 megapixel full frame sensor while the T7i has a 24.2 megapixel crop sensor. They both have the same ISO range of 100-25,600. The 5D III, despite being older, definitely has the superior sensor. On the other hand, the 5D II has a 21.1 megapixel sensor and an ISO range of 100-6400. In good light, it is better than a T7i but in low light things are a lot less cut and dried.

As a general rule, I’d say that any full frame camera released in the last decade is, if not as good as, at least in the same ballpark as a brand new crop sensor camera in most situations. Camera quality matters less than lens quality anyway.

What You Lose By Buying an Older Second-Hand Camera

It’s probably clear by now that, as long as a full frame camera isn’t too old or too badly beaten up, it’s likely to be better in many ways than a brand new crop sensor camera. Again though, things aren’t sewn up yet.

When you go with an older camera, you give up a lot of newer features. An incomplete list of things you probably won’t get includes:

  • Wifi or Bluetooth connectivity
  • A touchscreen
  • A tilt-swivel screen
  • 4K, high speed, or slow motion video shooting
  • A fast burst mode—which is an issue if you shoot sports or wildlife photography

These may or may not be things you’ll miss. You also don’t get the comfort and protection that comes with buying a brand new product. We’ll look at where to buy a good second-hand camera next but don’t expect an extended warranty or a replacement if something breaks.

Where to Buy a Good Second-Hand Camera

Buying a second-hand camera can be a bit risky. You don’t really know what you’re getting, especially if you buy from some stranger off Craigslist.

My advice is to buy from one of two places: your local camera shop or a reputable online marketplace like MPB.com and B&H.

With your local camera shop, you can go in and check the cameras out. The staff will also be able to advise you on your options. They will have cleaned up and checked out anything they’re selling so they’re unlikely to try and sell you a broken camera. They might even offer some kind of warranty.

It’s much the same with MPB.com and B&H. They’re two of the largest used camera marketplaces online. Anything they stock, they’ve tested and made sure it’s in working order. MPB.com offers a six-month warranty while B&H offers a 90-day one.

You will pay a bit of a premium buying local or from MPB.com or B&H but, in my opinion, it’s worth it.

So, Which to Choose?

Which option you go with is up to you. If you’re reading this article, there’s a good chance you’re looking for reassurance that image quality hasn’t changed massively in the last two years or that a touchscreen is now considered an essential feature—don’t worry. Good cameras are built to last and, if you buy one that’s been vetted and has a warranty, you’ll be alright. I think the manual controls, rugged build, and larger sensor are worth the tradeoff, especially if you plan on getting better at photography.

On the other hand, cameras have come on in the last few years. If you want the latest features—and I can’t fault you, Wifi control is awesome—then you need to get a new camera. The latest crop sensor cameras are incredible so go with which suits you best.
