Toen ik aan het zoeken was naar een nieuwe dSLR kwam ik al snel uit op de Nikon D5300Omdat ik de hobby wat serieuzer wou gaan uitoefenen besloot ik niet om een kitlens mee te kopen maar gelijk voor een beter alternatief te gaan.De zoekcriteria waren...

hoek@ 50mm: Iets minder chromatische aberratie te zien hier, voor de rest concludeer ik hetzelfde als op 29mm. Zoals de scherpheid testen al te zien was heeft de lens wel wat last van chromatische aberratie. Dit is uiteraard te corrigeren in Lightroo...

Sigma 17-50mm F2.8 EX DC OS HSM er et stærkt objektiv i god kvalitet. Det tager gode billeder og lysfølsomheden gør det til en skarp konkurrent til selv objektiver med mere zoom men mindre blænde. Hvis jeg selv ejede et Sigma 17-50mm F2.8 EX DC OS HSM...

Sigma 17-50mm F2.8 EX DC OS HSM 不是什么新镜头了，但这支在2010年推出的镜头放在今天的标准仍然称得上是一支相当出色的镜头，简单做了个试用，与大家分享。这支镜头最大的亮点，应该是采用了两块FLD镜片，大大改善色散、像差等现象，再加上超声波马达和OS防抖系统，该有的功能都算是齐全了。此外这款镜头是专门为APS-C画幅而设计的，用在全幅机型上会有暗角。造工上体现出了适马的最高水平，手感要远胜于适马17-70那支。镜片结构采用了17片13组的方式，正如前面提到过的采用了2片FLD...
