The a6700 is Sony's best APS-C body — a 26MP hybrid with a 1.5× crop factor, so an E-mount lens frames like a lens 1.5× longer would on full frame. A 30mm reads as a 45mm-equivalent, an 11mm as a 16.5mm-equivalent. And because it's E-mount, every full-frame FE lens works too (just cropped). Here's the kit that gets the most out of it — each pick shown in the simulator, crop already applied.

Quick picks
① Do-everything

Sigma 18-50mm f/2.8 DC DN

The perfect a6700 companion — a 27–75mm-equivalent standard zoom at a constant f/2.8, tiny, sharp, and a fraction of the price of Sony's G glass. If you buy one lens, buy this; it does most of everything.

② Vlogging wide

Sony E 11mm f/1.8

A 16.5mm-equivalent — wide enough for arm's-length vlogging and gimbal work — that stays tiny and fast at f/1.8. The a6700 is a video powerhouse, and this is the lens that unlocks it for talking-head and run-and-gun.

③ Fast prime

Sigma 30mm f/1.4 DC DN

A 45mm-equivalent "normal" prime with f/1.4 for gorgeous background blur and low light — for about the price of a nice dinner. The cheapest way to make a6700 photos look expensive.

30mmf/1.445mm eq

Want a premium wide? The Sony E 15mm f/1.4 G (22.5mm-eq) is the upgrade vlog/landscape prime. The Sigma 16mm f/1.4 (24mm-eq) is another great value wide. For portraits, mount a full-frame FE 85mm f/1.8 — it crops to a flattering ~127mm-equivalent — and check the framing first.

The 1.5× crop — free reach

The crop that "shrinks" your wides also stretches your teles: put a full-frame FE 70-200mm on the a6700 and it reaches like a 105–300mm. That's why APS-C is a wildlife and sports bargain. See exactly how any lens frames, with the crop done for you:

Common questions

Which single lens should I start with?

The Sigma 18-50mm f/2.8 — the widest useful range in one compact, fast lens. If you mainly shoot video or vlog, start instead with the Sony E 11mm f/1.8.

Should I buy APS-C or full-frame FE lenses?

Buy APS-C (E) glass for wides and standard zooms — it's smaller, cheaper and designed for the sensor. Reach for full-frame FE lenses when you want telephoto reach (the crop works in your favour) or plan to move to a full-frame body later.

Can I adapt other lenses to the a6700?

Yes — the short E-mount flange adapts EF, vintage and cine glass. Manual vintage lenses give the a6700 character cheaply, cropped 1.5×. Check any pairing in the simulator first.
