Home made macro lens

Sick for the last couple of days. Haven't been sick in 10 years or so, feeling much better today.
Instead of laying around, I found a cardboard tube and fitted a 2" glass 2x magnifying glass to one end.
I then mounted it to a swinging lamp base and shot through the other end. 15 minutes to construct and mount it
to the base. Here are the results.

    The idea works much better if you use an achromat instead of a single element lens which causes chromatic abberation

    Very crude I know, but I was seriously bored. Zip ties yes they are handy.
    The magnifying lens is held in place with paper clips with a 90 degree bend, for the lens to lay on.
    The lens fit perfectly inside the tube.

    Not bad. Does your camera have filter threads on the front of the lens so that you can get a decent close-up lens that doesn't have the chromatic abberation issues?

    <<MacGyver-like>>

    I'm good at being resourceful for sure. I was looking at the swivel stand, knew I had a couple of cardboard tubes and a magnifying glass.
    I thought to myself, could I construct a crude lens? Not going any further with it just a little fun.

    No it does not. I would have to get a an extension tube with set screws to mount it to the fixed lens, with a female
    threaded end for lenses.

    I believe this is what messydesk is referring to......these 3 macro lens cost about 15-30 bucks depending on what brand name ya buy.

    Is your lens a 72mm? if its not it won't fit. My Sony came with a 52mm......

    The Canon 250D (+4) and 500D (+2) are achromatic close-up lenses that should work quite well if you have filter threads. They're more expensive than the cheap kits of multiple lenses, but you get what you pay for here. If you're able to use one of these on a fixed-lens camera, you'll be able to zoom the camera toward telephoto a bit and still get close, which will give you the comfortable working distance afforded to users of a longish macro lens on a DSLR. I would probably choose the 500D for most applications.
  • lcoopielcoopie Posts: 8,873 ✭✭✭✭✭
    I have a fixed macro lens
    and a close up filter

    and I thought that what the filter does
    is allow me to get closer

    which is not helpful in coin photography

    ?

    I also have extension tubes which does the same thing?

    Cool experiment...
    Thanks for sharing. Better quality than I might have expected actually.

    Not bad for an experiment that didn't require duct tape.
    I brake for ear bars.

    Love the ingenuity incorporated into the design (I.e. paper clips, cardboard tube, already available lamp arm and zip ties.) Reminds one of some of the things POWs were able to come up with despite limited resources.
  • ConstantineConstantine Posts: 2,369 ✭✭✭
    Impressive shot considering the home-spun lens you created. Nice.
  • morgansforevermorgansforever Posts: 8,470 ✭✭✭✭✭
    Thanks for all the comments, this set up will be short lived. I just picked a 72mm adapter that
    will mount to my Fuji S3280 using 3 set screws. This has 72 mm female threads in the front allowing me to
    mount a 72mm lens. I'm gonna go with the 8x and 2x, probably from B&H Photo. I know the best route is a DSLR
    with a macro lens but hopefully this setup will produce some crazy macro shots.
