Sony, Sigma or Tamron?
All three make autofocus lenses that work properly on E-mount, including eye autofocus and in-camera corrections. The differences are real but narrower than brand loyalty suggests.
Sony has the widest range by a distance, the only options at the extreme ends (the fastest apertures, the longest reach), and the deepest weather sealing in its G and G Master lines. Resale is strongest here too.
Sigma is where the value is on crop bodies. The DC DN primes — the 30mm and 56mm on this page — have no first-party equivalent at anything like the price, and they are the reason an APS-C Sony kit can be genuinely cheap to build out.
Tamron competes on full-frame zooms by shaving range off each end. Its 28-75mm starts at 28mm rather than the 24mm of a first-party 24-70mm, and its 17-28mm stops at 17mm rather than 14mm or 16mm. In exchange you get a constant f/2.8, markedly less weight, and a much lower price — and Tamron standardizes on a 67mm filter thread across several of these lenses, so one polarizer and one variable ND covers the set.
The two lenses that cover most of what people shoot
If you are building a kit rather than filling a gap, the shape that works is one fast prime plus one standard zoom. The prime handles low light, portraits and anything where you want the background to melt; the zoom handles everything where you cannot move your feet.
On APS-C that is the Sigma 30mm f/1.4 plus the Sony E 16-55mm f/2.8 G. The 16-55mm is expensive — more than most crop bodies — but a constant f/2.8 across a 24-82mm equivalent range genuinely replaces two or three primes for run-and-gun work, and it is sharp corner to corner. Its honest costs are the price, the weight next to a prime, and that it has no optical stabilization, which matters on the many Sony crop bodies that have no in-body stabilization either.
On full-frame it is the Tamron 28-75mm G2 plus whichever prime suits your subject. At 540 g the Tamron is light enough to hang off one body for a whole day, and its 0.18 m close focus at the wide end is unusually useful for detail shots. It has no stabilization at all, so it leans entirely on your body’s IBIS, and 28mm is noticeably tighter than 24mm in a small room — the two things to weigh before buying it over a first-party 24-70mm.
Portraits, and why the 85mm is the one people keep
The Sony FE 85mm f/1.8 is the best-value portrait lens in the full-frame line and the one we would buy first. 85mm is the classic flattering length: long enough that you are not standing uncomfortably close, and compressed enough that it renders a face kindly. At f/1.8 the background separates cleanly, it is sharp wide open, and it costs a fraction of the f/1.4 G Master.
Two caveats worth knowing. It has no optical stabilization, so it relies on in-body stabilization or a fast shutter. And on an APS-C body it becomes a 128mm-equivalent lens, which is tight for indoor use — if you shoot portraits on a crop body, the Sigma 56mm f/1.4 is the lens that lands at the right field of view instead, and our portrait lens roundup ranks that whole decision.
Going wide without going broke
The Tamron 17-28mm f/2.8 is the sensible route into full-frame wide-angle. You give up the last few millimeters against a 14-24mm and you get a lens that costs far less, weighs 420 g, and — the part that matters most for landscape work — takes ordinary 67mm screw-in filters. A polarizer and an ND are how you control a sky and smooth water, and a bulbous front element that cannot take them is a bigger practical limit than three millimeters of extra width.
What it is not is the most dramatic wide-angle available. 17mm is wide; 14mm is startling. For tight interiors and big night skies that gap is real, and our landscape lens guide covers the wider options and what they cost.
What is missing from this page, and why
No G Master glass. Sony’s flagship line is excellent and we have no reason to talk anyone out of it, but almost nothing on it changes the recommendation for someone building a first or second lens kit: you are paying a large premium for a fraction of a stop, weather sealing and the last few percent of optical performance. When we can make the case for one on buyer value rather than prestige, it will appear here.
No telephoto either, beyond what our wildlife and sports lens guides already cover in depth — those pages rank long E-mount glass properly, and repeating them here would make this page worse rather than longer.
How we ranked these
What the lens does for the money first, which is why two picks are not Sony-branded; then maximum aperture and whether it holds across a zoom range; then equivalent focal length on the body it fits, because a 56mm on APS-C and a 56mm on full-frame are different lenses in practice; then weight; then filter thread. We have not tested these lenses — here is exactly what we do instead— and every figure quoted is the manufacturer’s own published specification with the date it was read. Where a maker publishes no stabilization rating, we say nothing rather than estimate one.
