Showing 1-10 of 20
very soft.terrible quality control overall, do not buy or try at least more
8 March 2013
Summary: tested 4 of these lenses , they were all VERY SOFT. recently i borrowed the same lens from a friend to give it another try. that one was sharp. also recently Sigma advertises with ; "enhanced quality control" . nice they more or less admit the previous era was terrible! And indeed the latest sigma's (end 2012, start 2013) are generally much better in IQ and QC.
Summary: I bought this looking for a 1.4 that didn't cost as much as the Canon 24mm or 35 mm L lenses. Despite good reviews, my experience was different. The autofocus was all over the map, picking peripheral extraneous points instead of an obvious subject. It consistently metered like an EV -1 producing underexposed pictures, requiring me to keep the EV on +1. The white balance was off too. I was nervous buying a non Canon lens for my 40D, and won't ever do it again.
Summary: The lens looks and feels great.According to the datasheet, I thought this would be the perfect prime lens to go with my D70.Unfortunately, focusing problems made the lens that I bought, useless for me. Read more below. Problems Encountered: I own another Sigma lens which I am very happy with - a 10mm-20mm DX zoom, also purchased at B&H, the prime lens I ended up using with my DSLR is the Nikon 35mm f/2, which is optically far better than the Sigma 30mm f/1.4,...
Excerpt: Kohdalle osui himmenninviallinen versio ja muiltakin olen kuullut, että tämä Sigman 30/1.4 on erityisen herkkä laatuvaihteluille. Erinomainen valovoima, mutta täydellä aukolla valitettavan pehmeä. Himmentämällä paranee, mutta ei loistavaksi missään vaiheessa. Ei kiinteäpolttoväliseltä tällaista odottaisi. Itse valitsin loppujen lopuksi Nikkor 35/1.8G:n.
Pros: + Laadukas fyysinen rakenne ja tuntuma (koko, tarkennusrengas ja yleinen tuntuma), + Mukana hyvä kuljetuspussi ja vastavalosuoja, + Ikkuna tarkennusetäisyydelle, + Hiljainen HSM
