Short answer: Sony’s support page lists 28 E-mount interchangeable-lens bodies for the NP-FW50 — ZV-E10, the α7 / α7R / α7S first and second generations, the APS-C models from α6500 down to α3000, the entire NEX line and the ILCE-QX1. Cyber-shot RX10 models and some early SLT bodies use the same cell but are not part of that E-mount list. Many bodies released later moved to the NP-FZ100, which is a different shape and does not fit. The reliable check is the label inside your battery compartment plus the official compatibility table, not “it is a Sony mirrorless camera”.
The official E-mount list, grouped
Model codes are more useful than marketing names because they are what is printed on the body plate and in the manual. Every code below appears on Sony’s NP-FW50 compatibility page. Some models carry a “compatible with restrictions” note there, meaning an individual function may be limited.
| Group | Model codes | Common names | Count |
|---|---|---|---|
| Full-frame | ILCE-7 / 7R / 7S / 7M2 / 7RM2 / 7SM2 | α7, α7R, α7S, α7 II, α7R II, α7S II | 6 |
| APS-C | ILCE-6500 / 6400A / 6400 / 6300 / 6100A / 6100 / 6000 / 5100 / 5000 / 3500 / 3000 | α6500, α6400, α6300, α6100, α6000, α5100, α5000, α3500, α3000 | 11 |
| NEX series | NEX-7 / 6 / 5T / 5R / 5N / 5 / F3 / C3 / 3 | NEX-7, NEX-6, NEX-5 family, NEX-3 family | 9 |
| Other | ZV-E10, ILCE-QX1 | ZV-E10, QX1 lens-style camera | 2 |
The table is useful as a negative list too: a body that is not on it should not be assumed to take an NP-FW50. Our NP-FW50 compatible cell states coverage of 21-plus popular bodies, a deliberately conservative count of commonly used models rather than the full official table. The two figures are not in conflict.
The boundary people get wrong: NP-FZ100
The NP-FW50 belongs mainly to the 2010–2016 generation of E-mount bodies. Sony later moved most new bodies to the higher-capacity NP-FZ100, with a different shell, contact layout and marking, so it physically cannot go into an NP-FW50 compartment. The FZ100 camp includes the α7 III, α7R III and later, the α9 family, α6600, α6700, and video bodies such as the FX3 and FX30.
The trap is that the names are almost identical: the α7 II takes FW50 while the α7 III takes FZ100; the α6500 takes FW50 while the α6600 takes FZ100; the ZV-E10 takes FW50 but that does not mean every later ZV body does. Even “the α6000 series” is a loose label that sometimes gets stretched to include the α6600 and α6700, neither of which is on the list above.
| Easy to confuse | NP-FW50 | NP-FZ100 |
|---|---|---|
| Full-frame | α7, α7 II, α7R II, α7S II | α7 III, α7 IV, α7R III and later |
| APS-C | α6000, α6100, α6300, α6400, α6500 | α6600, α6700 |
| Video | ZV-E10 | ZV-E1, FX3, FX30 |
Bodies outside this E-mount list
Sony’s page counts interchangeable-lens E-mount cameras only. Retailer and equipment references also list the Cyber-shot RX10, RX10 II, RX10 III and RX10 IV bridge cameras, plus early SLT models such as the A33, A35, A37 and A55, as NP-FW50 users. They share the same release era and the same W-series pack.
For any of those bodies, the compartment marking and the accessories page of the manual still outrank a third-party list. A list narrows the field; the label on the camera settles it.
Three checks before you order
- Open the battery door and look for
NP-FW50printed inside or on the compartment label. This is the least error-prone step. - Find the ILCE-xxxx / NEX-xx / DSC-xxxx code on the bottom plate and match it against the table above. Do not match against loose labels like “an a6xxx”.
- Decide whether you need a cell or an external-power accessory: the TNP-FW50 with USB-C has a port built in, while our NP-FW50 has none. Both are batteries and both fit the same bodies.
If you are still unsure, the NP-FW50 category groups articles by body and by capacity. Copying the exact model code into a question gets a far more accurate answer than describing “a Sony mirrorless camera”.
FAQ
Can the α7 III use an NP-FW50?
No. The α7 III (ILCE-7M3) takes the NP-FZ100, a different size that will not fit. The α7 and α7 II are the ones on the NP-FW50 list.
Which battery does the ZV-E10 take?
The ZV-E10 is on Sony’s NP-FW50 compatibility list. Check the marking inside the compartment before ordering; other ZV models with similar names should not be assumed to share it.
Is it 28 bodies or 21-plus?
Both, with different scope. 28 is the full count of E-mount bodies on Sony’s table, including older NEX and QX1 models. The 21-plus on our product page is a conservative count of popular bodies. Match your own model code and the question disappears.
Will a third-party cell be recognised?
The NP-FW50 is part of Sony’s InfoLITHIUM W series, so the body exchanges charge data with the pack. Compatible cells normally need a decoder chip to show remaining capacity. Camera firmware updates can occasionally change recognition behaviour, so no universal guarantee is sensible.
