Super close up rig, and yes, that's gaffer's tape! The only way that could be more redneck is by using duck tape.

I think I have a reverse coupler ring or 3 laying aroun

And the result of this little experiment:

You made a tiltshift!

Kinda.

You know, somewhere I have a few reverse couplers. If those lenses just happen to be 52mm filter ring I'd be happy to send one to you. (provided I can find where my wife "filed" it). I'd bet it would be less messy than gaffer's tape...

Why doesn't the leader board show up any more - did you guys burn it out? It was almost like watching one of those digital displays of time to the thousandth of a second - always flickering, although the board here didn't flicker (or it was too fast to see).

I appreciate it but I'll order one. You might want to start a "lens across America" type project and include it in that,

I think the admins took it off the thread pages in the hopes we would go away. It's still on the main, front TPF page.

There is a series of posts a hundred or so pages back on the LB's hiding.

Maybe I should use my 300 and 80-200 and reverse one ... see how that is .... nah .... i have better things to do

I saw where someone make a Lens Baby style T&S using PVC pipe and a cheap 50mm, I think. I'll have to look for it - another forum. I have a 35-80 that's hard to focus and zoom - that might be worth playing with.

Magnification would be 1.5 to 3.75. Go for it - I'll give you fifty post points.

HELL NO, WE WON'T GO!

HELL NO, WE WON'T GO!

HELL NO, WE WON'... bored now. See ya.

btw, I played with my new 300/4 lens.
pretty nice
I tried it with the 2x TC though and it lost some detail
but it's a cheap 600mm/8
and my other lens is a 160-400/5.6

I've been thinking about playing around with some of the lenses I got back a few months ago, either reverse lens or freelensing with some of them. Just haven't gotten around to it.

So, Charlie--what happens if I take my Tokina 100mm f/2.8 macro lens and reverse attach another lens to it, say a 50mm f/2? I've never really understand how to figure the magnification.

2x mag,

The longer lens (primary) is mounted on camera. The shorter (secondary) lens is reverse stacked to the primary. Set the aperture of the second lens at wide open.

Maginfication = primary focal length divided by secondary focal length, so 200/100 = 2. In my testing, I used a 50 and a 24; 50/24=2.08333.

 

[snowbear97]

If you reverse the lenses and put the short one on the camera, you get the opposite - 100 / 200 = 0.5. Like looking through binoculars backwards.

Luckily all of my lenses have 52mm threads, or rather the Nikkors do. The Vivi is 205mm max, close enough to the 55-200 Nikkor that won't bother with an adapter.
