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.
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.
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.
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.
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 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:
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.
