Sigma 60mm f/2.8 DN vs Sony E 35mm f/1.8 OSS

8($348.00 at Amazon)(Opens in a new window) resolves 2,055 lines at its maximum aperture, is capable of capturing more than twice the light as the Sigma, and is optically stabilized.

2: It is supposed to be a low-light fast performer, but I did not find that the image quality I got from it was better than the 18-55 NEX kit lens. I know that sounds crazy since the kit lens is 3.5F at its widest focal length, but it is true. I got this lens to compliment my small collection of E-mount lenses with a wide aperture lens capable of doing more than the kit lens

It's an impressive performer, delivering 2,342 lines per picture height at f/2.8 and virually no distortion. Edges are nearly as sharp as the center, and sharpness is even from f/2.8 through f/5

The Sony E 35mm F1.8 OSS lens offers a bright aperture and standard angle of view for capturing sharp images with a shallow depth of field.

I am used to using a DSLR with a 75mm lens but with this lens at 120mm I am farther away from my subject than I would like to be. However, I can accept this since the sharpness is so good. For the price paid, this lens is very hard to beat.

Best lens for the NEX cameras. I keep it on most of the time on my NEX-6, and rarely switch to the pancake kit that it came with. In fact, the pancake zoom has failed to work recently, after only about 4 months, whereas this is still going strong. No zoom that needs to be extended on power-on, so you can take turn your camera on and start taking shots very quickly

I already knew from other reviews about the clunking sound when it's not powered up, but there's another annoying noise it makes when it is powered up. The stepper for the aperture diaphragm chatters loudly as it opens and closes rapidly whenever light is entering the lens until you hold down the shutter button. The lens focuses quickly and accurately, but manual focus seems a little less responsive than my Olympus lenses. All in all, it's still a great value in a prime lens of that focal length, and I can put up with a few quirks as long as the picture quality is good

I've had problems with the aperture blades not working. The aperture simply stays full open (1.8) resulting in a number of totally overexposed shots. IOW, the lens views and focuses while fully open as it should but does not close down to the proper higher f-setting

The noise, or rattling, is part of the construction, the design, of the glass inside the lens. Once on your camera and turned on, shoot away with an amazing lens at a more amazing price. Thanks Sigma!

The build quality is great, and the focus ring feels smooth during manual focusing. Autofocusing is fast. With the recent firmware (v1.02) update on my NEX 5R camera, I get hybrid autofocus (CDAF and PDAF)

Two reasons why I didn't give it 5 stars: 1) the internal AF motor moves around and makes the lens feels like something is broken internally (it's just the design). 2) I'm not a fan of the "focus by wire" but it seems to work well. I also don't like the smooth focus ring. Having said all this, I really can't complain because it's super sharp and only $200

Because you need to adjust the aperture with the camera, instead of a ring on the lens, and the focus by wire nature of this lens can be a bit slow (as I feel they have got the ratio off by a small amount). In other words, you have to turn on ring on the lens way more than you should have to. This is great for very very fine adjustments, but for large adjustments it can be tiresome. The autofocus, on the other hand is an absolute delight
