Re: So who likes using a 2x TC?


More experimental than artistic, a moon shot with the 400/2,8 IS, 2X TC II and 2X TC III stacked. Resolution is approximately 50% of original.

It tried to autofocus, but the f/11 lens/converter combination would not allow that. I did get it to autofocus during live view, however, and it seems to be pretty accurate. A bit better than I could do manually with 10X magnification on the LCD panel, but I was experiencing some vibration that interfered with manually manipulating the focus ring.

It seems that 1600 mm amplifies minor shake A LOT!

Edit - a little more information - ISO 1600, 1600 mm, f/13 (exif says 9, need to add 2 stops), 1/160 with some contrast and exposure tweaks in DPP.
