請問各位師兄，當小弟把Nikon TC-201 2X 加於nikon 180mm f2.8 之後，在D700 上只能顯示f7 或f6 光圈，而測光也好像不能！是不是D700不能對應Nikon TC-201 2X 呢？請各位師兄指點!謝謝！

After adding the TC, largest aperture will reduce. I am also using D700. After adding TC-20e3, the largest aperture for my 70-200 F2.8 lens will change from F2.8 to F5.6 only. 測光 should not be affected. I don't know why.

多謝師兄指點，請問師兄是否將鏡頭lock 係f22,然後再用機身轉光圈呢?d700 機身要唔要特別set 比機知用緊增距環呢？謝謝！

Cannot say "指點" as I am not an expert - just to share the experience as we use similar camera/lenses. I don't think we need any settings on D700 when using TC. I did not. I assume your TC is TC-20eI (first generation)? I only used 2nd and 3rd so dont know about 1st. My 70-200 has a fixed F2.8 so I never have to adjust it on the lens. The D700 can totally control the aperture of the lens.

d700 機身要唔要特別set 比機知用緊增距環呢?
==================================
I don't think so.

唔該晒，師兄！番去再試清楚先！謝謝！

無用nikon dslr好耐，但據聞d3，d700可以手動選擇對應唔同嘅nikon ai／ais鏡profile作配合，而TC 201係畀手動鏡用嘅增距鏡，安裝在180 f2.8後，該鏡光圈會變為f5.6, 所以你可以選擇一枝profile係f5.6嘅如400mm f5.6 ed-if. 睇吓可吾可以cheat到佢！

多謝師兄指導，但我嘅情況係支鏡set 咗f22 ，但唔知點解D700顯示最大光圈只得F7.....請問有冇nikon 2x 增距鏡可以用係冇ASI嘅鏡但仍能對應埋AF 呢？謝謝！

應該無！只要你其中一樣(鏡／增距器)係手動，都應該做吾到af. 不過nikon好耐之前出過一個TC 16A,加喺F4，F801同F90／90X上可以將AIS鏡行使自動對焦。但應用係現今DSLR上面，我估佢啲接點同TC 14E/20E所控嘅野已經吾一樣。所以應該用吾到！
