Default Inverted Lens for macro?

I have been reading quite a lot of posts on results and techniques that an inverted SLR lens serves the purpose of being a macro lens.

I have two questions.

Can a filmSLR lens be used for this purpose?

If I find a way to attach both, how do the results turn out to be?

Since the film SLR lens is the one being inverted there shouldn't be any problem as there can't be any communication with the camera body. Results will depend on the quality of the lenses involved.

I've seen both filter thread to filter thread and filter thread to camera mount inverters.

Hmmmm... I've never heard of this!!! Is this just a matter of turning a lens around and attaching it to the camera body???

Okay one final question on this issue, can you please guide me to a reasonable link perhaps where I can get some information about inverting, say, a lens XXYY abc-def mm, for my Fz40 and a D3100?

I haven't had the fortune to read loads on it yet, but there is this technique apparently.

They even have commercially available inverted lens mounts to go with this kinda gimmickry.

I searched Google for "reverse lens macro" and got a number of hits on the technique. Perhaps if you add your specific requirements you may find someone who has tried it. This isn't a new technique as 40 years ago I had a 50mm Rokkor macro lens that came with a filter thread to lens mount reversing adapter.

Lots of people do this. Go to B&H or Adorama,they have reversing rings for just about any camera. I reverse my 50mm. I even put my 2x TC on , then reverse the 50 on that and then add a 1x, 2x,3x close up filter to that and achieve somewhere around 2:1. The biggest problem is that you have a very limited DOF and you need LOTS of light. It's a lot better getting a macro lens if you're interested in macro. I do it my way because I'm not all that interested in macro and don't want to spend any money on a macro lens.

What you need for Nikon cameras is called the Nikon BR2 (about $40) or a generic equivalent. Also you will want an older lens that has a aperture ring or you will be stopped all the way down all the time.

OK I just did these they are hand held in low light so not so sharp but you'll get the idea


Nikon D5000 the 18-55mm kit lens held on backwards with a BR2

first shot at 55mm


Next at 18mm Notice how small the Depth of field is

If you drill out the center of a rear lens cap and put it on the reversed lens, you will have the aperture wide open and you can adjust it by turning the cap. If anyone is interested, I'll be glad to post photos of how I rigged my 50mm.
