Pros: Solid construction, bokeh, sharpness, excellent microcontrast, AF speed, no AC
Cons: Nothing, maybe the famous 24mm vignetting but nothing dramatic
Opinion: Yes, in the end I took this Sigma glass to replace the Lumix 24-105 f4. A choice considered for a long time because the Lumix is a great lens, but the Sigma quality and the f2.8 aperture were decisive in the final decision. Having the Lumix 70-200 I also wanted to rationalize the kit, completed by the Sigma 14-24 f2.8 DG DN that I own, and count with a valid lens also for video shooting. Praised in dozens of editorial reviews and videos (take a look at Youtube), loved by many professional photographers and enthusiasts. So, fantastic goal, if ever there was any doubt. Superlative sharpness, perfect contrast, CA practically absent especially at focal lengths and lower apertures, distortions under control, very well managed flare or almost absent. Light vignetting, easily solved in PP, while I point out the presence of a delicate and progressive bokeh thanks to the f2.8 aperture and the 11 blades of the diaphragm. Pro construction like every Sigma Art, weight adequate to the general quality, perfectly balanced on the Lumix S1 on which it is mounted, lightning AF on a par with native optics, very fluid and regular rings and a very useful function button that I use for selecting the focus area, hood with lock button. I thought that any alternative could make me regret the beloved Lumix 24-105, but this Sigma replaces it perfectly and painlessly, offering more even at the expense of the lower focal length. I also point out the reduced focusing distance (18 cm on the 24mm focal length) and the gasket on the bayonet that protects the lens and camera from dust. It is not stabilized, but the excellent stabilization of the S1 makes up for the lack. It must be said that some specimens have presented dust tightness problems, with dirt infiltrating the front lens block. Sigma has provided free total cleaning and dust tightness adjustment for specimens that have registered this problem up to serial number 55641775. Beyond this serial the lenses produced have been updated with a dust and dirt proof seal, definitively solving the problem. To conclude, Pro objective to which to deliver your creativity without fear, with the certainty of using a truly valid tool in terms of optical performance, versatility and general quality. All with a very affordable price. |
