一起点评一下适马50/1.4 HSM
<p>我用的是DX40也是我第一台单反。目前一直套头18-55，一直55-200/3.5-5.6</p><p>想加已知定焦大光圈。原来看中的是适马的30/1.4。</p><p>年底了准备入手中，发现适马又新出了50/1.4，不知道究竟怎么样啊，有人用过么？77mm的滤镜好亮骚啊</p><p></p><p><table cellspacing="1" cellpadding="2" width="230" border="0"><tbody><tr><td width="100" bgcolor="#ffffff"><span style="FONT-SIZE: 9pt;
