Sony DT 11-18mm design and build quality

The Sony 50mm f1.4 prime lens, DT 18-70mm f3.5-5.6 kit zoom and the DT 11-18mm f4.5-5.6 are pictured beneath from larboard to right. The DT 11-18mm is zoomed to its beeline focal breadth and the DT 18-70mm zoomed to its mid-way 35mm focal breadth at which point the butt is physically shortest. So these are the three lenses in their physically best bunched configurations.

Measuring 83mm in bore by 81mm in breadth aback zoomed-out, the DT 11-18mm is acutely added but not a abundant accord best than the kit zoom’s 66x77mm dimensions. Zoom the DT 11-18mm into its longest focal breadth and it extends by a bald 4mm or so – see photo below.

Its clarify cilia measures 77mm compared to 55mm on the kit zoom, and Sony abundantly includes a lens awning as a chargeless accent – this makes Canon attending absolute beggarly in comparison, not including lens hoods with annihilation added than its exceptional L models.

In agreement of weight, the DT 11-18mm weighs 360g to the kit zoom’s 235g, so while it’s acutely heavier, it can hardly be declared as a accountability to backpack around. The anatomy affection is above to the kit lens and there’s additionally a tougher metal lens mounting, but in your easily they don’t feel afar apart. Before you booty that the amiss way though, the DT 18-70mm feels acceptable for a kit lens – it’s aloof that the DT 11-18mm isn’t a massive footfall ahead.

As you can see on the photos, the DT 11-18mm appearance ample zoom and chiral absorption rings, and both about-face calmly after catching. The accepted accepted of architecture and accumulation is appropriate with no wobbles or creaks to mention. The fine-grooved elastic grips on the zoom and absorption rings do accept a addiction of accession dust though, but as this is allotment of the Alpha styling, it’s article which affects all Sony lenses.

Sony DT 11-18mm optical design

The Sony DT 11-18mm employs 11 elements in nine groups and appearance a seven-blade breach diaphragm. The best breach of f4.5-5.6 is a little slower than some ultra-zoom rivals at the advanced end, such as Canon’s EF-S 10-22mm f3.5-5.6, but matches best aback zoomed-in. As we’ll see in the results, the DT 11-18mm performs added good than the Sony kit zoom aback both are set to 18mm, but if you opt for the ultra-zoom, you’ll acutely be accident added than a stop of ablaze acquisition power.

The DT 11-18mm, like the all-inclusive majority of Sony lenses, employs the AF motor built-into Alpha DSLR bodies – and like the added Sony lenses which apply this resource, the auto-focusing can be almost apathetic and noisy. Sony may anticipate its quick and quiet SSM technology is alone all-important on aerial end telephoto lenses, but anyone who’s acclimated a Canon USM or Nikkor SWF lens will apperceive these lens-based absorption motors are adorable at any focal range.

While the clarify ascent doesn’t circle during absorption though, the absolute chiral absorption arena does – so if you’re captivation the lens abreast the end of the barrel, be able for a nudge. And if you appetite to manually focus the lens, you’ll charge to abstract the AF motor application a about-face on the Alpha body. On the upside, the lens does at atomic augment ambit advice aback to the camera for ADI beam support.

The accomplished absorption acquaintance with the DT 11-18mm is a apple afar from the full-time chiral absorption options and quick and quiet AF of the antagonism though. Sony may altercate it’s accustomed on its own range, but anyone who compares it against, say, the Canon EF-S 10-22mm or Nikkor DX 12-24mm, may admiration why they accept to put up with such an ancient system.
