One more test shot with the mod TC-16A, this time with the 135/2:
Modified TC-16A teleconverter test with 135mm f/2 AIS by labecoaves, on Flickr
Great Kiskadee captured at ~4m of distance. This is a ~20% cropped image.
D7000 + TC-16A modified teleconverter + Nikkor 135mm f/2 ais hand held, ISO 320, f/4(=8) at 1/250s. Though exif shows a 145mm f/8, in fact this was an effective 216mm f/6.4 (x 1.5 crop factor of D7000 = 324mm lens).
We need at first manual focus and then activate the AF by the modified TC-16A. I would say it is a 80-85% MF work and just 15-20% AF - the lens movement inside TC16A is truly limited.
It appears to have a slight front focus; I need to confirm this and AF-tune the combo.
Curtis, if this is forbidden here, please, let me know and I will put just a link instead of the image.
