只听说过有反接镜头的办法，但没有尝试过。反接的话镜头如何固定？

以前没玩过微距，但自从慕美能达50微和百微两个犀利镜的大名入了之后才深感微距魅力，在没什么大的景色可拍的地方，几朵花几个虫子可以让你玩半天，而且微距的影像世界充满着美丽和独特，展现出各种平时我们根本看不到的细节，非常让人着迷。

我觉得微距片子要出彩关键在于提升放大倍率以展现出更多细节，但提升到超过1:1的倍率需要添置设备，同时拍摄难度也会成倍增加。最近在考虑上一个增倍接管，但貌似用在老美AF的微距镜头上不能调节光圈，这个问题不知如何解决？

Breaking news! Sony Announces Addition of Uncompressed 14-Bit RAW Still Image Capture for New α Cameras!!!!

http://www_sonyalpharumors_com/category/miscellaneous/Sony Alphauniverse just broke the news! Sony will add uncompressed 14-Bit RAW on the A7sII and via firmware upgrade on the A7rII and later to many more cameras. Read here:

Sony Electronics, a worldwide leader in digital imaging and the world’s largest image sensor manufacturer, has today announced user selectable Compressed and Uncompressed 14-Bit RAW image capture will be featured in the new α7S II once it arrives in stores this October.

Additionally, they have announced plans to add user selectable compressed or uncompressed 14-Bit RAW still image capture via firmware update to additional cameras beginning with the recently introduced α7R II full-frame mirrorless model.

“The voice of our α community remains the most important guiding force of our product development plans,” said Neal Manowitz, Deputy Vice President for Digital Imaging at Sony Electronics. “The addition of Uncompressed 14-Bit RAW processing is a direct result of customer feedback. Widely requested by photo and video enthusiasts, we believe the choice of RAW processing types will further elevate the performance of these extraordinary cameras.”

The α7S II and α7R II are compatible with Sony’s growing lineup of α -mount lenses, which now totals 63 different models including 12 native ‘FE’ full frame lenses. By early 2016, Sony will add an additional 8 new lenses to its FE full frame lineup, bringing the FE total to 20 lenses and the overall α -mount assortment to over 70 different models.

Wow! That’s a huge news! And as I reported yesterday the new FE lenses will be announced right before the Photoplus start in October! Expect new 24-70m GM, fast prime lens, telephoto len, 21mm FE Loxia and more.

And I can’t wait to see how much difference the 14BIT will make on my Sony A7rII! Thanks Sony for listening to your customers!

:总结得好good:+100
做个有主见、求真的人。

豆娘很小，

图片很精彩。

为了拍这豆娘，已经把老百微的放大倍率用到了1:1的极限，
对焦只能靠前后移动机身来完成，因为转动对焦环的同时也会改变1:1的放大倍率。
我拍微距纯粹是为了好玩，没有那么专业，微距头带在身边，碰见好看的花和虫子什么的就拍一拍，
对于和我情况类似的朋友说几点心得：
1、老美能达的百微和50微用到1:1的放大倍率是一个什么概念？
     像豆娘这类比较小的虫子的复眼，用1:1的放大倍率，在7r2上拍出来100%看就是下图的效果。
2、拍虫子身上的纹路和汗毛一般都没问题，但想要拍清楚复眼时，即便7r2的高感已经足够好，但仍然要尽量避免使用ISO400以上
     因为当你放大到100%时，和复眼的大小相比，噪点会变得比较可观的，因此尽量使用低ISO
3、必须固定住相机，有条件就使用脚架，没脚架看能不能把相机放在某个固定的台面上。
     手持的话很难控制相机不会前后移动，需要特别好的运气才能刚好在按下快门的同时把焦点放在眼球上。
4、因为微距的照片通常都需要大幅的截图，用到100%的画质，需要像素级别的清晰度，
     所以尽可能用上一切可以保证清晰度的手段，除了固定机身，电子前帘、延时自拍、小光圈、较快快门速度、辅助光源等等。

借花老的地盘，喜欢微距的朋友多交流。

发图祝贺，以后我的7R2拍到什么图，就发到这里好了，让花老指点指点。

转接美能达老百微拍的豆娘，感觉这张拍的特别萌

感谢你，

其实你看国内外一些测试就可以，

我也是看他们的测试和评价买东西，

只是我多了一个自己实际去佳能体验店操作或者在摄影城的二手店实际操作来得到自己的第一感受，

我回国会去使用这几种镜头感受转接的效果，

因为我也关心其中的几只。

能够期待花老对EF镜头转接做一个测试吗？比如11-24，24-70II，70-200ISII，35L，50L这些常规镜头。
本人期待了很久，一直希望有一个客观公正的摄友能说几句。

看来退休后时间是咱自己嘀，

一定又拍摄了很多好照片。

刚从外地回来。才看到花老的强帖，学习并继续关注中……
