A quick question about reversing a lens. Is a reversed 50 only good for shooting extreme close up like small bugs and closeup eyeballs? Or can it be used for closeups of flowers frogs ect?

Jim,

I can be used for any thing you care to photograph. Given the limitation of the working distance. If you can get with in 4 inches of a frog etc. you are on the right path.

I'm not having any luck at all with hand holding my 50mm reversed. I tried taking shots of a lady bug and some flowers today. I've tried all shutter speeds and I cannot get a good, clear shot. All the photos come out hazy and blurry. They looked like cell phone camera quality or something. I was going to buy a reversing adapter but I need to figure this out first. Any ideas anyone? Thanks alot!

Finally got my reversed 50 on a tripod. Worlds of difference in sharpness.

Sorry boring subject, but proves my point. This was indoors at night. f5.6 1/1.6 sec. The lens is canon FL 50mm f1.8 which is nice because there is a ring right next to the aperature ring that I can turn to stop it down. Only bummer is that it takes a 48mm filter so I need to use a 48 to 52 step up ring to use the reversing ring.

I was going to try my Nikon 50mm 1.8D just now, but it appears that the step up ring is stuck inside the reversing ring. That's ok, it's getting late.

I got two reverse rings for the 50mm f/1.8 to directly couple to the camera and to another lens. Reversing it onto another lens is difficult, at least for focusing. Maybe I'll save it for when I have enough to get a rail (or enough time to do one myself). Reversing the 50mm directly onto the camera, however, is awesome. Thanks to Tom for posting these 2 threads, and thanks to others who took time to answer my stupid question (particularly mbaumser for showing that trick to set the aperture of the lens).

Here's the result:

This is taken handheld, so it's not good. But I'm still excited about what this can be done.

Just a thought, has any one hacked a mount for the MT-24 to fit a reversed a 50? If so would you share your idea.

Thanks Thomas

Sorry for the dumb question, but how do you set the aperature for an ef lense with it reversed?
thx

George,

You mount the lens in normal fashion and set the aperture, depress the DOF button and while the aperture is stopped down take off the lens. The aperture will stay stopped down and you will be able to reverse mount it.

This looks like a great vacation from all of the soccer/football teams I've been shooting this month. I'm going to try to dig out my old minolta and see what lenses I had for it.

Just received my fotodiox reversing ring today. Can't wait to try it out...

Does anyone know whether you can use the depth of field preview button trick on a 40D with an EFS lens. I don't want to take it off and damage the camera or lens. Otherwise, I guess I'll shoot wide open for now.

Thanks all.

I have a few questions regarding this reverse set-up. First of all it seems some properties have a inverse relation while others maintain the properties of a lens that is normally mounted.

For instance, focal length is inverse to magnification so the shorter the FL the greater hte magnification.

But aperture is still the same, so a high aperture f/8 still results in a greater dof than say f/1.4, correct?

Also, I noticed in the other thread comparing 50mm lenses that magnification differed quite significantly, why? Is it due to the lenses normal max magnification? Would a lens with a greater magnification also have greater magnification when reverse or would it be inversed? Or is this completely unrelated?

What would happen if I take my macro lens and reverse mount it? At 1:1 with a 60mm macro would the magnification remain unchanged? What if it is at 1:3, would this effect the magnification and how?

Essentially I want to move beyond 1:1 magnification. But with my Sigma 70mm it is already too long at 1:1 so I cannot use a hotshoe mounted flash or onboard as the lens casts a shadow thus requiring a off shoe bracket. But with an inverse 28mm or 35mm I get greater than 1:1 magnification and the lens is incredibly short so I can use my hotshoe mounted flash or even the onboard one.

So, now I'm looking at some 28 and 35mm primes and wondering how I can determine which 28 or 35mm lens will provide the most magnification. Essentially, if I have 4 35mm lenses can I use max magnification or min focus distace to determine which lens will have the greatest magnification when reversed.

Saw this thread in the main part of the forum and remembered these shots I fooled around with a couple days ago. These were made by stacking/reversing a 50mm f1.8 on my 105mm f2.8 macro lens. Not the most technically perfect shots but the first one, especially, illustrate to me the insanely thin DOF we macro folks work with.

I have a really dumb question (at least I suspect it's dumb). There are discussions of several sizes of lenses being reversed (the part that normally holds the filter is mounted on the camera, right?). Well - the external optics on lenses are all different sizes, so do you need size-specific reversing rings? And what goes on the part that normally mounts on the camera?

I told you - dumb question. But heck, while I'm at it - here's more . . .

I have two old manual Minolta lenses (boy, I loved that old camera). One is a 45mm prime (I think it's 45mm - not more than 50mm), and I have a zoom lens - probably something like 28-75 or whatever they made back then; I'd have to check. I currently use Canon bodies. Can those old manual lenses be used for reversing?

If anyone has read this far - thanks! I appreciate any info I can get!

p.5 #20 · p.5 #20 · rev 50 revisited.

Marcy, I picked up a reversing mount on E-bay for just at $20 + S&H, $23 total. The native thread on the mount to reverse to is 58mm, will fit the 50mm f/1.4, several of the 28-XX lenses, the 18-55 family and others. I also have a couple of manual lenses that I picked up a 49-58mm step up ring to mount an Olympus Zukio manual 50mm f/1.8. I've found the 50mm to be very good on either a FF or wither crop, 1.3x, My 1D Classic and 1.6x, my 30D, depending on the subject. I'd like to find a very inexpensive 28-XX lens to get more magnification on the wide end. Very neat concept, and don't need a ton of money...

The manual lenses are a little more convenient to change the aperture in mid focus/shoot. With the auto focus lenses, you have to mount the lens normal, adjust the aperture and use the DOF Preview, and while holding that unmount the lens, and then reverse mount it. Poses another problem when using apertures stopped past f/5.6 cause the VF is very dark.
