Canon **RF-S** optics are **APS-C–native** designs for crop **[EOS R](/photography/canon/canon/)** bodies (**R7** / **R10** / **R50** family). Same **RF** bayonet as full-frame lenses; the difference is image circle and typical size/price. Full-frame options on the same mount: [RF lenses](/photography/canon/rf-lenses/).

- **Same bayonet as full-frame:** **RF-S** lenses use the exact same **RF** mount as [full-frame **RF** glass](/photography/canon/rf-lenses/) — you can swap them on the same camera body.
- **Built for APS-C only:** they cast a **smaller** image than full-frame lenses — **enough for R7 / R10 / R50** sensors, **not** for a whole **full-frame** chip. On bodies like **R5** / **R6** / **R8** you would normally see **strong vignetting** (dark corners) or uncorrected coverage; Canon intends **RF-S** for crop **EOS R**, not as full-frame tools.
- **Full-frame RF on your APS-C camera:** you can mount **any** **RF** lens on **R7** / **R10** / **R50** too. The sensor uses the **centre** of the bigger image, so coverage is fine; framing is **~1.6× “longer”** than on full frame — often quoted as **35 mm equivalent** (e.g. a **50 mm** **RF** prime gives about the same angle of view as **~80 mm** on full frame).
- **Suffixes on the barrel:** **L**, **IS**, **STM**, **USM**, **Macro** mean the **same thing** as on **RF** lenses (build class, stabilisation, focus motor, close-focus design). Table of meanings: [RF lenses](/photography/canon/rf-lenses/) (*Lens name suffixes*).
- **What Canon actually sells as RF-S:** **five** general **zooms** (kit / travel / ultra-wide / **power-zoom** wide–standard / tele) plus **two** compact **VR / spatial** lenses with **twin front optics** — still **no** normal **RF-S** **single-focal prime** from Canon (aside from those VR models); see tables below and [Prime lenses](#prime-lenses).

### Standard zoom lenses

| Lens | Notes | Price |
|------|--------|------|
| [RF-S 18-45mm F4.5-6.3 IS STM](https://www.canon.cz/lenses/rf-s-18-45mm-f4-5-6-3-is-stm/) | Compact basic kit zoom | **~8 000 Kč** |
| [RF-S 18-150mm F3.5-6.3 IS STM](https://www.canon.cz/lenses/rf-s-18-150mm-f3-5-6-3-is-stm/) | Better one-lens APS-C travel range | **~13 990 Kč** |

### Wide-angle lenses

| Lens | Notes | Price |
|------|--------|------|
| [RF-S 10-18mm F4.5-6.3 IS STM](https://www.canon.cz/lenses/rf-s-10-18mm-f4-5-6-3-is-stm/) | Ultra-wide APS-C zoom for travel and vlogging | **~9 990 Kč** |
| [RF-S 14-30mm F4-6.3 IS STM PZ](https://www.canon.cz/lenses/rf-s-14-30mm-f4-6-3-is-stm-pz/) | Compact **14–30** mm with internal **power zoom** (PZ) for smooth video; **58 mm** filter; pairs well with **R50 V** / gimbal work | **~10 000 Kč** |

### Telephoto zooms

| Lens | Notes | Price |
|------|--------|------|
| [RF-S 55-210mm F5-7.1 IS STM](https://www.canon.cz/lenses/rf-s-55-210mm-f5-7-1-is-stm/) | APS-C tele companion to 18-45 / 18-150 kits | **~11 490 Kč** |

### VR and spatial 3D (dual optical unit)

Two compact **RF-S** lenses with **paired front optics** for stereoscopic capture (Canon VR / spatial stills & video). Output is usually processed in **EOS VR Utility** or the **EOS VR Plug-in for Adobe Premiere Pro** (see [Canon VR system](https://www.canon.co.uk/virtual-reality/)). Body compatibility evolves with firmware — check the lens’ official specs for your **EOS R7** / **R50** / **R50 V** (and updates) before buying.

| Lens | Notes | Price |
|------|--------|------|
| [RF-S 3.9mm F3.5 STM DUAL FISHEYE](https://www.canon.co.uk/lenses/rf-s-3-9mm-f3-5-stm-dual-fisheye-lens/) | ~**144°** immersive fisheye pair; strong **VR / 180°**-style workflow; rear **30.5 mm** filter / gelatin holder; **STM** | **~37 000 Kč** |
| [RF-S 7.8mm F4 STM DUAL](https://www.canon.co.uk/store/canon-rf-s-7-8mm-f4-stm-dual-lens/6795C005/) | ~**63°** natural field of view for **spatial / 3D**; optimised for closer subjects; **58 mm** front filter thread; very light (**~130** **g**) | **~15 500 Kč** |

*UK RRP converted with rough **£1 ≈ 29.5** **Kč** (spring 2026); local offers differ.*

### Prime lenses

Canon does not list a conventional **RF-S** single-focal prime (aside from the dual-optic VR pair above). Standard **RF** primes cover the APS-C sensor on the same mount.

### Macro, teleconverters, and longer reach

Canon does not sell **RF-S–only** macro primes or **RF-S** teleconverters. **1:1** macro, long telephoto zooms, and **Extender RF** pairs are all in the full-frame **RF** lineup on the same mount — check Canon’s compatibility charts before buying.

**Firmware:** keep camera firmware updated for AF and lens communication.
