Arek - Czw 14 Lis, 2013 Temat postu: Test obiektywu Sigma A 24-105 mm f/4 DG OS HSM http://www.optyczne.pl/in...ywu&test_ob=311 Zapraszam do lektury! Arek hijax_pl - Czw 14 Lis, 2013 Fajny obiektyw ale zupełnie nie rozumiem dlaczego akurat taki szkieł wypuścili. No chyba, źe to stary projekt był i już odleżakował swoje... MM - Czw 14 Lis, 2013 Niech lepiej wypuszczą 400/5.6 ze stabilizacją 
Koniecznie z możliwością podpięcia TC Canona 
Arek - Czw 14 Lis, 2013
Albo niech wypuszczą swoje konwertery w nowej wersji. Pewnie mogą zrobić lepsze niż oryginały jak się postarają. MM - Czw 14 Lis, 2013 Problem w tym, że jak ktoś już ma komplet TC Canona... a te obecne od Sigmy są zwyczajnie słabe. dcs - Czw 05 Mar, 2015 "dpreview: There were some rumors going around that your 24-105mm zoom lens was discontinued. Obviously the rumors were untrue, but has that lens performed as well as you'd hoped? Kazuto Yamaki, CEO of Sigma: I'm happy with the optical performance of the lens as a standard zoom. This kind of lens is among the most difficult to design because it covers wide-angle, through standard to telephoto. The ideal construction of a wideangle lens compared to a telephoto is very different. So we need to compromise to some extent. And the 24-105 has good performance for that type of lens. In the market, its performance hasn't been excellent, but it's OK. The rumor about discontinuation came about because we can't supply it in enough volume. We forecast demand for this lens as being very low, so we didn't plan to make many. But at some point they all sold out, and we then suddenly had a lot of orders placed - but then it takes four months[to restart production]." http://www.dpreview.com/a...sigma-interview |
