    Re: 400mm f3.5 + TC301 on D2X - problems

    Thanks all for your help -Jack, Marcel... i had already tried different methods of mounting the TC and lens in combinations, and nothing works

    Lenswork - thanks for that detailed info.. makes things very clear now, but still not sure why i get proper readings from f3.5 to f22, when starting in this direction, but not backwards from f22 to f3.5, where the ap ring no longer works, and the display remains at f22...see below

    I had got to the point where i could get to see F3.5 in the display, as long as i had the aperture ring on F3.5 ( obviously ), and the aperture coupling tab on the TC ( body mount side ) pushed round to its natural stop. Then, as the aperture ring was moved from F3.5 to F4 / F5.6 / F8 / etc etc, the display would show all apertures correctly as I moved the Ap ring towards the minimum aperture.

    But....soon as I moved the Ap ring back from minimum, to maximum , the display remains at F22 and the Ap ring no longer works. I have to start again by getting a finger nail onto the Ap coupling lever on the body side mount of the TC, push this to its stop, then i get the display changing immediately to F3.5 again, and as before, i can then go to F4/ F5.6 and all the way to F22, and the display will show each aperture in turn. And once again, soon as i reverse the action and come back to F3.5, the display remains at F22, and Ap ring does not work at all on its way back to F3.5. Then i have to use the fingernail once more to shift the Ap coupling lever back to its stop....blah blah

    PS what i called the Ap coupling lever is the one you pointed ( No. 4 ) on the diagram, Lenswork. Thats the little lever that i keep moving with my fingernail when TC and lens is mounted on the D2x

    Problem solved.

    The track that coupling tab on the TC runs in, thats the tab that lines up with the aperture tab on the lens, was slightly dinged in. It took some better eye glasses to spot the ding, it was that small. It was this ding that was grabbing the tab and not letting it spring back.

    Yeah life can be good - if you dont weaken, as my elders used to say !

    I did a sample shot today after fixing the TC last night. A 200 ft shot, 800mm @ effective f7. The 4,200 pix 100% crop is a bit ropey, but once downsized to something reasonable like 1500, then IQ looks better
