Okay, let's be clear. If you're reading this, it's because you've been going back and forth for days about ditching your phone and moving to a real camera. And you're right to do so. But watch out, because the second-hand market is full of traps for those who don't know what to look for. I've spent years seeing cameras come and go through the shop, and I'm going to tell you exactly what's worth it, how much you should shell out, and how not to end up buying a problem shaped like a camera.
Why a used mirrorless and not a new phone?
I'm not going to fool you with the megapixel talk. Your phone takes 50 MP photos, and that's it. But the sensor of a mirrorless, even if it's APS-C or Micro Four Thirds, is physically much larger. That means better low-light performance, that natural background blur you love so much on Instagram, and a shutter without lag that you notice as soon as you try photographing something in motion.
And then there's the electronic viewfinder. Seeing the exposure before you shoot is a huge paradigm shift. No app can give you that. You learn more in three months with a camera like that than in three years shooting blindly with your phone.
The system matters more than the body
Here's the key that almost nobody tells you: when you buy a mirrorless, you're buying an ecosystem of lenses. A camera with a Sony E mount has hundreds of available lenses, many at bargain prices. A dead proprietary mount leaves you with no options and a camera hanging around your neck. Choose the system before the model. Always.
The four systems you'll come across
If you're looking for second-hand mirrorless cameras, the market is divided into four families. Let me summarize them without the fluff:
Sony E
The king of the second-hand market. Huge lens selection, from 30 euros to whatever you want to spend. The APS-C bodies from the 6000 series are an excellent entry point, and the autofocus has always been among the best. The downside: the menus on the first generations are a maze.
Fujifilm X
The favorite of those who want to feel they're handling a real camera. Physical dials for speed, ISO, and compensation. The colors it produces are legendary, and the build is solid. The problem: Fuji lenses are expensive compared to Sony. If your budget is tight, a Fuji body and a 35mm equivalent prime, and off you go.
Micro Four Thirds (Panasonic and Olympus)
Smaller sensor with a 2x crop factor. But the lenses are tiny and the cheapest on the market. Ideal for travel and street photography. The focus isn't as lightning-fast as Sony in action, but for almost everything else, it's more than enough.
Canon EF-M
The mount is officially frozen. That's scary, but it means there are bodies and lenses being given away. The M50 is a great option to start with very reliable focus. However, don't expect Canon to release new lenses for it.
How much do you really need to spend?
I'll be honest. In 2026, with the market stabilized, these are the ranges I deal with on a daily basis:
- Basic, €150-€300: Older but decent bodies. With this, you already surpass your phone in image quality, but accept limitations in battery life and autofocus in fast scenes.
- Intermediate, €300-€550: Here are the cameras that won't leave you wanting more for years. Fast autofocus, decent 4K, and already professional handling.
- Advanced, €550-€900: Bodies that professionals use as a second unit. If you get here, you won't regret it.
My golden rule: don't spend more than 70% of your budget on the body. A good body with a bad lens gives worse photos than a mediocre body with a decent piece of glass. Leave room for the lens and a fast SD card.
Models I do recommend, level by level
Basic level
The Sony NEX-5 - Compact Mirrorless Camera is one of those that started it all. It's old, but the sensor still holds up, and the price is a steal. Perfect for deciding if this photography thing is for you without breaking the bank.
The Sony Alpha NEX-3N is its little sister, even more compact. Ideal for always carrying it with you. However, don't expect quick controls or a viewfinder other than the screen.
The Canon EOS M100 is one of the cheapest on the market. No viewfinder and only one dial, but with some of the best autofocus of its era. To move away from your phone, it's more than enough.
Intermediate level
The Olympus Pen E-PL7 is a gem for urban photography. In-body stabilization, tiny size, and a retro style that captivates. Olympus's menu is peculiar, mind you, but you get the hang of it.
The Olympus OM-D E-M10 is probably the best value for money in the MFT system. Electronic viewfinder, top dials, and stabilization that saves you in any situation. A perfect travel companion.
The Fujifilm X-T20 (BODY ONLY) - Mirrorless Digital Camera has those Fuji colors that hook you and dials that invite you to touch. Autofocus is good, not lightning-fast, but for portrait, landscape, and street it's wonderful. If you like manual control, look no further.
Advanced level
The Fujifilm X-S10 is the one I recommend when someone wants the best without overspending. In-body stabilization, comfortable grip, and the same sensor as the more expensive X-T models. A camera for years.
And the Nikon 1 J4 is the odd one out. 1-inch sensor, super fast burst, and tiny. Ideal if you want something for sports or action without carrying weight. However, the lens system is limited. Think carefully before diving in.
Quick comparison
| Model | Used price | Strengths | Weaknesses |
|---|---|---|---|
| Sony NEX-5 | ~120-170€ | Price, APS-C sensor, light | Slow autofocus, short battery |
| Olympus OM-D E-M10 | ~250-320€ | In-body stabilization, size | MFT sensor, complex menu |
| Fujifilm X-T20 | ~400-480€ | Colors, dials, quality | Expensive lenses, AF just okay |
| Fujifilm X-S10 | ~550-650€ | Stabilization, grip, sensor | Average battery, price |
Mistakes I see every week in the store
Buying the body without thinking about lenses
It's the most expensive mistake. The camera is the body, but the lens makes the photo. Before buying, check our second-hand lens section and get an idea of what to expect. If the system you like has expensive lenses, maybe another one suits you better.
Obsessing over the newest model
Cameras don't become obsolete like phones. One from 2018 is still perfectly valid in 2026. The difference between one model and another doesn't justify paying double if your budget is tight. Buy what you need today, not what you might need in a hypothetical future.
Ignoring the shutter count
It's the camera's mileage. 100,000 shots on a 2014 camera is normal; on a 2019 one, it's a sign of wear. Always ask for it before buying. If the seller doesn't know, there are ways to check it with a photo.
Not checking rubber grips and dials
The rubber grips degrade and the dials loosen. It's not a fatal defect, but it's a negotiation point. If they are sticky or peeling, ask for a discount. The fix is cheap and you can do it yourself.
Buying without warranty
This is the most important point. A mirrorless camera is a complex electronic device with mechanical parts. It can fail a week after buying it. Never buy without warranty, unless the price is so ridiculous that you can absorb the loss. In our store, all second-hand mirrorless cameras undergo a 27-point check and come with 12 months of warranty. That's the minimum you should demand.
Beyond the body: lenses and filters
If you enter the MFT system, the 7Artisans 25mm f/1.8 - Micro Four Thirds Fit is a bright and very cheap prime that opens you up to low-light photography without breaking the bank. It's manual, but you'll learn more with it than with any kit zoom.
And a tip I wish I had received: buy a UV filter from day one. The B+W 67mm F-Pro 010 UV-Haze MRC Filter protects the front glass of your lens from knocks and scratches. It costs little and saves you a big headache. A scratched lens has no cheap solution.
Where to buy and how to secure the purchase
You have three channels: private sellers (Wallapop, eBay), specialized second-hand stores like ours, and outlets from large retailers. Each has its pros and cons.
Private sellers offer the lowest prices, but you assume all the risk. You don't know if the camera has suffered a knock, if the shutter is at its limit, or if it has lived in a humid environment. Specialized stores charge a bit more, but in return you get a check, warranty, and someone to claim to if something fails. For me, peace of mind is worth it.
So now you know: choose a system, leave room for the lens, check the shutter count, and don't buy without warranty. If you have doubts about any model, drop by the store and we'll look at it together. This photography thing is much more fun when you start on the right foot.
