big lens + d60 + crop factor 1.5 = wow

Blake Billings , Oct 20, 2012; 07:53 p.m.

just got an old tamron 500mm mirror adaptall lens with a 2x teleconverter with nikon mount and leica mount

i put my new toy on the d60 and mounted on the tripod... we're talking roughly 1500mm here... still trying my technique and going to use this for shooting lunar pics....

the shake is my biggest fear... but wow ... it's an impressive looking deal... pics to come soon

first test shot......

still working on getting this configuration working with no camera shake...

tripod, iso 100, tamron 500mm mirror lens with 2 x converter with a camera that has a 1.5 crop factor... that makes this roughly a 1500mm lens this is some serious lens capacity... it shakes like a heroin addict going through withdrawals....er... scratch that... it shakes like michael j fox....

but nonetheless, check out the lunar craters -- just shot this

I know the D60's sensor is not too great at high ISO, but you might get better results if you raise it to, about 400 or even 800, so you can raise the shutter speed and, if you want a lighter moon, the exposure.

it shakes like michael j fox....

That's unfair. Michael J. Fox can't help his shaking, it's the result of a terrible disease, but possibly you could, by applying intelligent technique, and maybe using a better tripod and head.

i have a really good slik brand tripod....

am playing with the setup, it's a big ole lens and for the shot i had to have the tripod stems and neck raised to high ---

it's just gonna take some experimentation to get my technique down ---- with the 2x teleconverter, I'm losing a lot of light

Wow, a Nikon D60, an old 500mm mirror lens and a slik tripod. That is impressive! The photo of the moon is almost in focus, CA isn't too bad and the exposure probably isn't off by more than a stop or two and the composition is...well it is a composition. Will you be entering this in any competitions soon?

Matt Laur , Oct 21, 2012; 05:11 a.m.

Keep the tripod's vertical mast down. Consider weighing things down to stabilize, and - as Hector mentions - giving up a tiny bit of high ISO noise in favor of a higher shutter speed. Were you using the self timer to avoid physically pressing the shutter release at the time of exposure?

Hector Javkin , Oct 21, 2012; 06:33 a.m.

Ray, that is hilarious!

Mike Halliwell , Oct 21, 2012; 06:57 a.m.

Without knowing the shutter speed, maybe it's Lunar movement?

If you've got a strong enough tripod +head, put a 2LB bean-bag on top of the point above the head, probably where the lens joins the body and use the self timer. Some tripods allow you to hang weights from beneath as well. More mass = more damping.

If you feel the camera is still moving from the shutter release or mirror-flip, use the very old method of using, say, a 4 second exposure with a black card shading the lens for the first 2 seconds and then whip it out of the way for the last 2.

Make sure not to touch the set-up...that big magnification works on camera shake as well as the Moon!)

" .........and for the shot i had to have the tripod stems and neck raised too hig..........." maybe go somewhere where you can see it from about 3ft up, and sit on the floor next to it?

Ray. Too much or too little coffee today.....? :-)

I am not sure the OP would appreciate Ray's comments.

However, the problem is indeed that regardless of how great your tripod/support maybe, addinga a 2x TC onto a 500mm mirror lens is not going to yield very good image quality. Years ago, I used to have the Nikon 500mm/f8 reflex lens and it was difficult enouth to get good images on the F4; adding a 2x TC is not exactly making it easy. The D60 has no live view, but on a body with that feature, live view may help focusing, but you probably will never get an image that can be loosely considered sharp.

With that find of focal length, essentially you need to use two tripods to stop vibration, one tripod for the lens and one tripod for the body. Needless to say, that would be a pain to use. And with a 500mm mirror lens + 2X TC, I doubt that using two tripods would help much.

I do believe we're feeding a troll here.
