3. 尽量从有保修和退货政策的经销商或技术助理处购买

人们经常认为,购买二手设备自动意味着如果它不能工作,你就没有保障或保修。 是的,如果你从互联网上的个人或甚至亲自购买相机或镜头,这是真的。 但如果你从公司购买,情况就完全不同了相机和镜头)和转售设备通常提供3至6个月的保修,包括缺陷情况下的退货政策。 因此,从技术助理那里购买通常是一个不错的选择。 毕竟,他们交付的设备已经过测试和修改。 寻找你所在地区的技术助理,看看他们是否有二手设备出售。

4.购买二手相机或镜头,最好是作为备用。

明智而谨慎的做法是,千万不要购买二手相机或镜头作为排练或活动报道的主要设备。 毕竟,无论你做多少次测试,都不可能检查二手设备的所有部件。 因此,购买二手相机或镜头作为活动中唯一的主要设备是相当危险的、最好将这种设备作为备份,或偶尔使用,或在出现任何故障的情况下,我们可以重做照片。

5.快门寿命计数

每台相机都有一个寿命,我们可以通过每次点击时触发快门的次数来衡量。 通常情况下,快门可以发出10万至20万次点击,之后它们会随时停止工作。 当然,这个快门寿命因型号而异,所以在你购买二手相机之前查看设备已经发射的子弹数量,并检查制造商告知的使用寿命。

例如,佳能EOS 5D Mark II的快门在平均点击17万次后就会停止工作。网站//www.olegkikin.com/shutterlife 显示了尼康、佳能和索尼几种型号相机快门的平均寿命,而网站//shuttercheck.app/data有一个超级完整的佳能型号列表。 下面我们列出了佳能和尼康主要型号的使用寿命:

佳能相机型号 快门寿命
佳能1D X Mark II 500.000
佳能5D Mark II / III / IV 150.000
佳能6D Mark II 100.000
佳能7D Mark II 200.000
佳能60D / 70D / 80D 100.000
佳能T5i / T6i 100.000
尼康相机型号 快门寿命
D4 / D5 400.000
D500 200.000
D850 200.000
D3500 100.000
D5600 100.000
D7500 150.000

索尼没有正式披露其相机的快门寿命。 该公司披露快门寿命的机型只有A7R II、A7R III和A9,所有这些机型的额定点击次数为50万次。

检查传感器

除了检查快门的使用寿命,另一件非常重要的事情是检查相机传感器是否处于完美状态。 取下镜头,手动提起快门,观察传感器上是否粘有灰尘、划痕或真菌。 如果只有灰尘,很容易清洁。 要测试传感器上是否有其他缺陷,如像素缺失、斑点或颜色变化,可拍摄一张照片如果有任何问题,你会在这张照片上注意到。 如果一切正常,现在用镜头前的盖子拍另一张照片,这样你会有一张全黑的照片,你可以再次检查传感器上是否有任何缺陷。

7. 检查和测试二手镜头的重要细节

如果你想买一个二手镜头,在完成交易之前要检查以下细节:

  • 拿着手电筒照一下镜头,先照正面,再照背面,看看是否有划痕或真菌。 如果你有这些问题,你在自动模式下的对焦不可避免地会出现问题,同时也会在照片中出现这些瑕疵。
  • 检查镜头上是否有跌落或磕碰的痕迹,因为这可能会大大影响镜头的内部电路,导致故障。
  • 另一个重要的测试是在自动模式下进行对焦,然后在不同的焦距下以手动模式进行对焦,如果是变焦镜头的话,检查它是否在所有条件下都能完美工作。
  • 最后,改变镜头所有光圈的光阑,看看它是否能完美工作。
