Sigma Contemporary 65mm 2.0 DG DN für Sony E schwarz

The Sigma 65mm f/2 DG DN Contemporary may not be a mainstream lens but this doesn't make it any less desirable. It isn't all that fast and fairly heavy compared to similar lenses. However, it's also one of the best lenses in the 50-75mm class - on multiple levels. The optical performance is excellent, if not outstanding. The image center is extremely sharp and the quality in the outer image field is still impressively high even at f/2. At f/4, the lens shows true greatness. Lateral CAs are pretty low. And it doesn't stop there - the bokeh is silky smooth with very pleasing out-of-focus highlights. LoCAs/bokeh fringing is present at large aperture settings but that's true for the vast majority of fast lenses. RAW images exhibit some vignetting at f/2 and image distortions aren't perfect either. However, image auto-correction will take care of this. The build quality of Series I lenses is exceptional and the 65mm f/2 is no different. If you like having the quality of a vintage lens combined with modern optics and AF, this is it. The lens body is made of (thick) metal and the aperture and focus control rings just feel awesome. The magnetic lens cap as well as the metal lens hood add to the luxurious impression here. The environmental sealing doesn't seem to be optimal, though. Sigma is only mentioning a mount gasket. However, the inner focusing system should help in this respect. The AF is may not be the fastest on the market but it's certainly sufficiently quick and silent. If you haven't noticed, we are pretty thrilled by Sigma's new offering here. And if you are a sucker for premium glass, the Sigma 65mm f/2 DG DN Contemporary Series I is definitely worth a look. Highly recommended!

The Sigma 65mm f/2 DG DN Contemporary is another superb I-series lens from Sigma.

The Sigma 65mm f2.0 DG DN achieves a convincing balance between quality, size, and price. It's very sharp at least in the APS-C image circle, shows little longitudinal color aberrations and low vignetting and distortions (through lens profile), and produces a nice Bokeh. Its size makes it a good fit for a mirrorless camera and the full metal body leaves the impression of solid build quality and ruggedness although making the lens heavier than need be. Be aware though that the lens has no special weather sealing, focus breathing could be lower, and field curvature softens the corners of flat or distant subjects a bit. All-in-all though - assuming that the AF problem is an individual glitch on my copy of the lens - I'd reward the Sigma 65mm f2.0 DG DN a Recommended!
