Intro: Hacking Macro Bellows
How to take some junk macro bellows and modify them to work for your dSLR, point and shoot, and digital video recorder.
Cost: 5-10 usd
Step 1: Gathering the Junk
there are 3 parts which are needed to hack some old bellows and make them into something you can use on your dSLR of choice, point and shoot, or to make video of small things.
Those are the old bellows (preferibly 35mm, brand doesnt matter as long as they are light tight), a body cap for your dSLR (skip this part if this is for a point and shoot) and some way to mount the lens.
Also needed is some 5 min epoxy, a file, a knife/drill, electric tape.
In this case i bought a titan body cap (to fit a nikon ai mount) and i used the cheepo lens cover that came with the kit lens. My bellows were given to me as a set of junk cameras and are Miranda Focabell s. Whatever that means. No camera came with is, so its junk. If you can not find bellows in your basement or local pawn shops, check ebay. Remember, any crappy bellows will work.
Step 2: Round Peg Into Square Hole
Once the parts are gathered, you have to trash the lens cap and body cap. The clear plastic piece gets the middle cut out to the edges, same with the body cap. Note: I didnt remove the treads that lock the body cap to my camera. Most important. Also take time to note how the bayonet mount of the body cap attaches, so when this is finally assembled your bellows fit on right (i messed up on this part as you'll see later)
cost up to this point, 5$ for the titan body cap from hunts photo and video.
Step 3: Epoxy!
now is the most difficult part. all you have to do is epoxy the body cap to the back of the bellows, and the lens cap to the front of the bellows. I double checked to make sure that i could still mount the lens with the macro bellows rail in the way. No problem!
The only way i could let my 5 min epoxy set was setting the bellows on end. This was proped up by the disused kit lens.
Step 4: Light Proofing
The clear plastic lens mount will cause ghosting and all sorts of problems. I covered it with a single layer of electric tape (For a photo student, i have no idea why i dont own gaffers tape).
At this point, it is important to check for other light leaks, cover the lens cap end with black paper and look thru the body cap side. Any points of light must be delt with.
This is the bellows mounted on my dSLR. Notice it isnt level... my own fault.
Step 5: Using the Beast
Note: No autofocus, No automatic apature, no ttl metering.
This is in the relm of guess and check.
The lens is a 50mm nikkor. I recomend this lens for any nikon dSLR. Best quality for the lowest price. Anyways, for focusing it has to be set to f1.8 (or f2.8) then stoped down to get the DOF you need. Using a 'g' series lens which is without an apature ring means you will be stoped down to the highest apature all the time making focusing a really big problem. go buy the 50mm. I havnt got this to work with my 24mm nikkor nor have i tried with the kit lens (18-55) or my telephoto (55-250). I dont care to try. My information of bellows is that a normal lens (50mm ish) or wide angle will be the best bet.
SO i mount the lens on my camera, point it at somthing then move the bellows in and out. untill it looks in focus. I set a shutterspeed in ""Manual mode (m)"" on my camera because any auto mode will not work at all, as the camera belives there is no lens mounted. I shoot a pic.
I adjust focus according to the lcd screen on the back of my d50 and take another stab at exposure. When i have a properly exposed well focused macro image, i will then trade shutter speed for apature until i get the depth of field i want.
This is a 100% crop. Notice the fine detail. The edges are a little softer, but this is macro photography and that is expected.
Step 6: Video Camera or Point and Shoot
set the camera or video camera to manual focus, focus as close as possible then point the video camera or point and shoot into the macro bellows. Use the cameras zoom untill the frame is filled with the circle of light projected by the mounted lens.
Use the focusing nob of the macro bellows untill the subject is in sharp focus. I made a video of my gf's eyeball moving about, but it isnt of the quality im willing to show here. But i am very confident that this can be done well.
