What is a cheap full-frame DSLR body that shoots RAW?
The cheapest full-frame DSLR that shoots RAW is a used original Canon EOS 5D, commonly listed at roughly $190 to $250. Sony makes no full-frame DSLR, so the closest Sony answer is the mirrorless Sony α7 II, which records ARW RAW files on a roughly 24MP full-frame sensor and adds 5-axis in-body stabilization.

01Context
Does Sony Make a Full-Frame DSLR?
Why a Sony buyer ends up comparing an old DSLR with a mirrorless α7 body.
No. Every Sony full-frame interchangeable-lens camera is mirrorless. The α7 series uses an electronic viewfinder instead of a mirror and optical finder, and it takes Sony E-mount lenses rather than DSLR mounts.
For a RAW shooter the practical result is the same: a full-frame sensor, interchangeable lenses and RAW capture. Sony bodies save RAW files with the ARW extension, which mainstream editing software reads like any other RAW format.
So the real decision is between the lowest-cost full-frame DSLR on the used market and the cheapest sensible Sony system. You can browse current Sony full-frame cameras on sale alongside this guide.
02Used DSLRs
Which Full-Frame DSLRs Cost the Least?
The two older bodies that set the price floor for full-frame RAW, and what you give up.
Canon EOS 5D and Nikon D700
The original Canon EOS 5D from 2005 is the lowest-cost answer. It records 12.8MP full-frame RAW files, shoots at about 3 fps with a 17-frame RAW buffer and has a 2.5-inch, 230,000-dot fixed LCD. Used examples are commonly listed from about $190 to $250.
The Nikon D700 sits at a similar used price, around $250, with a 12.1MP full-frame sensor. It is generally the more capable action and low-light body of the two, and it suits photographers who already own Nikon F-mount lenses.
Both are stills cameras from another era. The original 5D records no video and has no live view, neither body has in-body stabilization, and autofocus is far behind modern subject detection. Old batteries, card slots, seals and shutters may also need attention.
The body price can mislead you. A usable lens, battery, charger and memory card can cost as much as the camera itself, so price the whole kit before you call it cheap.
03Sony pick
Why the Sony α7 II Is the Budget Sony Answer
A stills-first full-frame body for portraits, landscapes and travel, and a natural step up from Sony APS-C.
- Sensor
- Full-frame CMOS of roughly 24MP. Sony lists 24.2MP while some independent specifications list 24.3MP, almost double the original 5D.
- RAW format
- Records Sony ARW RAW files; independent specifications list 14-bit RAW support in relevant shooting modes.
- Stabilization
- 5-axis in-body stabilization, which Sony rates as equivalent to a 4.5-step faster shutter speed for stills and movies.
- ISO range
- ISO 100–25,600 standard, with ISO 50 available as an expanded setting.
- Battery and weight
- About 350 shots per charge and approximately 556 g body only, so carry a spare battery.
- Trade-offs
- Slower startup and operation than newer bodies, less advanced autofocus and Full HD 1080p video only.
04Compare
Old DSLR, α7 II or α7 III?
How the three routes to cheap full-frame RAW differ in practice.
Older full-frame DSLR
Lowest body price and an optical viewfinder. No in-body stabilization, dated autofocus, and the original 5D records no video.
Sony α7 II
Cheapest practical Sony full frame: about 24MP, 5-axis stabilization and E-mount lenses. Best for portraits, landscapes and travel stills.
Sony α7 III
24.2MP back-illuminated sensor, 693 phase-detection points, 10 fps, 4K 30p, about 710 shots per charge and dual card slots.
05How to choose
How to Buy Cheap Full-Frame Without Overspending
Work through these steps in order so the body price does not hide the system cost.
- Set a total budget that covers body, lens, battery, charger, memory card and RAW editing software.
- Choose the lens system first: Canon EF, Nikon F or Sony E-mount, because lenses outlast bodies.
- Price a usable lens before buying the body, since full-frame lenses can cost more than a used camera.
- Pick the body by use: Canon EOS 5D for the cheapest stills, Nikon D700 for low light and action, Sony α7 II for cheap modern full frame, Sony α7 III for events, action and video.
- Buy in person or from a seller with returns, then test the shutter, card slots, dials, autofocus, battery, hot shoe and ports.
- Open sample RAW files at 100% magnification to check for dust, banding, dead pixels and exposure problems.
06Avoid
Common Mistakes With Budget Full-Frame Cameras
The errors that turn a bargain body into an expensive system.
- Do not confuse full frame with professional: an old full-frame body can be slower and less reliable than a newer APS-C camera.
- Check the shutter count, because mechanical wear matters on older DSLRs and mirrorless bodies alike.
- Do not expect modern autofocus from the EOS 5D or D700; neither has subject recognition.
- Remember that α7 bodies use E-mount, and Sony states adapted lenses work with optional adaptors only, with function varying by adaptor and lens.
- Budget for replacement batteries and a compatible charger when buying an older camera.
- Plan for RAW storage and editing, since RAW files are larger than JPEGs and need processing software.
- Treat a very low price with caution: sensor marks, a damaged card slot or a failing shutter can erase the savings.
