Re: Manual Focus Nikon Glass


Rafael, your last moon image with the "2240mm" lens is simply outstanding, not only by the image itself - crisp and sharp, but also by the technical difficulty - 3 TCs! Truly a feat!!

I have used a similar to yours procedure when shooting moon, but I left the mirror up for more than 10 sec, sometimes even more than 15sec to avoid any residual vibration.

I have some "old" moon images with the 800mm + TCs, at least one or two already posted here, anyway, you estimulate me to post them again and share some TC combos:


With the TC16A ( not so bad in the 800/5.6 as you have found for the 400/3.5):


_DTR2508 800mm+TC16A = 1280mm by labecoaves, on Flickr

D300 + 800mm f/5.6 ais EDIF + TC 16A = 1280mm f/9 @ f11 [x 1.5 crop = 1920mm].
Tripod + cable release. I think this is not bad for an overlooked and old TC.


One of the first test shots with the mod TC20EIII + 800/5.6 (1600mm x 1.5 DX= 2400mm!):


Moon 800mm f/5.6+TC20EIII = 1600mm f/11 by labecoaves, on Flickr

D300, ISO 200, 1/50s at f/16(=8), tripod, MLU during 20 sec, cable release.
Spot metering, -0.33 EV. Just a small pass of smart sharpen was applied, amount 50, 0.2 px.



And one of the craziest TC combos I made until today:


Moon shot with a 1904mm telephoto by labecoaves, on Flickr

D3 + TC17EII + TC14A + Nikkor 800mm f/5.6 ais EDIF = 1904mm f/13.
We need a sturdy tripod + Mirror lock up + 10 s to wait any vibration finnish.
Exposure was 1/50s at f/22. Some levels adjustments; ~30% cropped, resized to internet and a small pass of smart sharpen 50 x 0.2 px.
For my surprise the image appears more than usable.
