俄罗斯 鲁比纳尔 500/5.6

那是什么东西啊？

我们这有，价格800－1000左右，也许还要稍高些，不知您能接受的最低价是多少？

看过

那个反射膜寿命应该还是可以的，至少70年代产的那些也没有被氧化。我手里这个头从02年开始用，到现在依然完好。

800到1000我能接受,但镜子是什么情况的您有照片吗?
方便的话发到我的信箱行吗?

没有照片，镜子质量肯定没问题，以前有同好在我这里买过，不过那里现在有没有货我要去看一下，然后在回复您。

等楼主收到,拍个深空给我们看看啊,我关注这个头也很久了.就是不知道彗差会不会很大,所以一直有些犹豫

我一直不晓得哪个反射的膜有没有寿命   很好奇  有人知道吗？

如果同好谁那里有的话，我也求一个N口的（价格800~1100元)，要求：使用正常、镜片没问题，无严重磨损、划痕、掉漆的。
一般是镀银的，镀的越好(越密实)越耐用，和镜子放时间长了以后损坏的情况一样，好一样可以用N年，N>10...

是的毒很深,已经不行了 ,时间再长点就该住院治疗了.姆托的10/1000和这个比怎么样?

那个太重了，据说对焦更难一些。主要看楼主用什么相机(支持手动头自动测光就好了)。现在也有自动对焦的折反头，如美能达、肯高。。。

楼主可以向赵玉春老师咨询一下俄头的情况，北京那里或许能买到这款俄头，价格可能会相对便宜一些，甚至低于800元！

It's physically impossible for a Mirror lens NOT to render out of focus highlights as doughnuts. And, I would also point out that there is sample to sample variation. The Tamron 500mm f8 is mechanically excellent, but optically mediocre, in my experience with multiple samples. I found that the Soligor C/D 500mm f8 that I picked up for

$60 on ebay was just as good. Personally, that's what I'd recommend: Get one that was mechanically well made for cheap used on ebay, and see if it meets your needs. If it doesn't, you can sell it for just about what you paid for it. If it does meet your needs, you got an adequately good lens for really cheap.


The ones I'd recommend trying for are either the Soligor C/D, The Tokina, or the Spiratone 500mm f8, as these are each as good as the over-rated Tamron, IMHO, and they are noticeably less expensive used.

The MTO is quite good optically, but it's much bigger than most.

The Celestron (not the excreble C90) and Questar are quite good, but much more expensive.

Most mirror lenses are awful but others are rather good, especially when you consider the cost. Do remember that they have a lot of limitations like ugly bokeh, low contrast, inability to change aperture, no AF etc.
Happy shooting,

也就是说：“如果折反镜价格太贵，买了就不划算了。”

I am sure that some folks have success with mirror lenses. You could be one of those, but I wish someone had told me to avoid mirror lenses before I bought mine.
