Sony DT 11-18mm f/4.5-5.6 Reviews

Ephotozine reviews the Sony DT 11-18mm f/4.5-5.6 and writes;
“Chromatic aberrations, the cause of purple fringing in digital images, are well controlled in the centre of the images but the corrections fail somewhat towards the edges.. Contrast and colour rendition are nice and go a long way in overcoming the resolution shortcomings, producing an overall pleasing image.”

Popphoto reviews the Sony DT 11-18mm f/4.5-5.6 and writes;
“Lens bench test data showed Excellent sharpness and contrast at the three tested focal lengths, in keeping with the majority of performances among today’s digital-only ultrawides. In DxO Analyzer 2.0 tests, barrel distortion was in the Visible range at 11mm (0.49%), and in the Slight range at 14mm and 18mm (0.27% and 0.13%, respectively). These are among the best distortion performances in the digital-only ultrawide category.”

Photozone reviews the Sony DT 11-18mm f/4.5-5.6 and writes;
“Typical for most dedicated APS-C lenses the Sony 11-18mm DT produces some vignetting at wide-open aperture but the issue is actually well controlled for an ultra-wide lens – the maximum vignetting remains below 1EV and when stopping down by 1 f-stop the problem isn’t really significant anymore (for this type of lens).”
Rating: ★★★☆☆

Photoreview reviews the Sony DT 11-18mm f/4.5-5.6 and writes;
“Imatest testing showed the DT 11-18mm to be a good match for the Sony DSLR A100′s sensor. We achieved the highest resolutions at around f8, with a slight fall-off in sharpness between the centre and edge of the field. However, most users would be hard pressed to see much difference in overall sharpness across the aperture range when the lens is in general use. Lateral chromatic aberration was so low as to be negligible. “
Rating: ★★★★☆

Cameralabs reviews the Sony DT 11-18mm f/4.5-5.6 and writes;
“The Sony DT 11-18mm delivers an ultra wide angle range which perfectly complements the standard DT 18-70mm kit lens. It essentially takes over where the kit lens stops, capturing a progressively wider field of view until you find yourself at 11mm and enjoying 104 degree coverage. Certainly if you’ve ever zoomed-out your Alpha general purpose lens and wished it went wider still, then this is a lens you should be considering very seriously.”
Rating: ★★★½☆

Kurtmunger reviews the Sony DT 11-18mm f/4.5-5.6 and writes;
“The Sony DT 11-18mm lens has sub-par color fringing control, and the corners at 11mm are pretty soft, but again, in proper use you won’t notice the corners, and they look exaggerated due to the nature of super wide lenses. The centers are very sharp wide open, and that’s real good, light fall-off is controlled well, and 11mm distortion is not noticeable in normal photos, and is nearly gone by 14-15mm. Ghosting is average, but veiling glare control is above average. “

User Opinions

Sony DT 11-18mm f/4.5-5.6 User Reviews

Great Sharp Lens | Rating: ★★★★☆
“This lens performs as advertised. It’s sharp, clear without any noticeable color fringing or shift..requires no color adjustment that I can see. “ – by ROSE RN

superb wide angle lens | Rating: ★★★★★
“I saw the Sony 11mm/18mm wide angle zoom lens passing through Frankfurt airport, I thought it might be useful for the rare occasions when the 18mm is not quite wide enough. Fortunately I waited to buy until I returned to the US, where it cost 50% of the price in Euros. This is another exceptional lens, with quite astonishing performance. As with any super wide angle lens, there is a risk of distortion on straight vertical lines, but far less than I’d expected. The 11mm/18mm is now in my travel kit. It’s great. “ – by Avedon if only

Quality and Beauty, | Rating: ★★★★★
“What I will say is that so far I’ve had some damn good photos using this lens having made the mistake previously of buying a wide angle Minolta lens. Which now having read a bit realise that it isn’t when on a digital camera because of the film frame size compared to the photsensitive chip used in digital jobbies.” – by M. G. Chisholm

Watch for ideal price before purchase | Rating: ★★★★☆
“Great lens. Be aware that it is a DT lens and therefore will only work on APS-C sensors. Basically, if you are never going to shoot old Minolta 35mm SLRs or the upcoming A900 body ($2500+ probably), don’t worry about it. “ – by J. Coates

wide wide-angle range, handicapped by variable aperture, | Rating: ★★★★☆
“Solid, sharp and virtually distortion-free wide angle zoom for Sony Alpha. However, non-para-focal construction handicaps usability because of variable aperture. Come on Sony, surely you’ve got the resources to design a constant f/4 aperture wide-angle zoom at this price point. “ – by Rudy

Was not sure. Now I am | Rating: ★★★★★
“Then I decided to give a try to the ultra wide angle. Now, I have to admit I love it very much. The couple Alpha 700/Sony 11-18 is very fast. The pictures are sharp, the color are rather accurate (I get what I see) and there is no barrel distortion (depending how you compose the picture, of course). “ – by Olivier Douin

Sony DT 11-18mm f/4.5-5.6 Aspherical ED Super Wide Angle Zoom Lens for Sony Alpha Digital SLR Camera, | Rating: ★★★★★
“It produces sharp images in my opinion and the super wide angle pictures are awesome. To me, it is well built. Whoever is reading this review, stop reading it, stop reading “official” lens ratings and resolution test results on the Sony 11-18mm super wide angle zoom lens and go get one, and you will not be disappointed.” – by Paul J. Adams

Features & Specifications

Sony DT 11-18mm f/4.5-5.6 Specifications

The perfect lens for fast shooting — interiors, crowd scenes and more. With the capability to focus quickly and zoom from super-wide-angle to wide-angle, this lens captures interior scenes with greater flexibility and handles fast action in close environments. Its DT design is ideally suited for the APS-size CCD imager of the Sony Alpha DSLR-A100 camera — and its 35mm-equivalent zoom range of 16.5mm to 27mm gives you wide latitude in framing and composition.

Lens Features
Internal focusing system
Lens elements at the rear of the optical system move, allowing rapid auto-focus response.

Aspherical lens elements
Aspherical elements correct frame distortion to provide more visually accurate super-wide-angle shots.

ED (Extra-low Dispersion) glass
ED glass lenses minimize flare and greatly reduce chromatic aberration, giving you photos with sharper focus and more accurate color separation.

Circular aperture
In low-light shots or nightscapes, out-of-focus light sources have a pleasing circular defocused effect.
