Lens cap holder – Never lose your lens cap again

Where do you keep your lens cap when you are shooting? I keep mine in my pocket. But i may give this DIY a try it look quite simple.

This diy is to create a holder that makes it easy to attach the lens cap to the camera strap. Quick to use, the cap can be attached from above or below.

Materials you need:
- A piece of plastic, size 45 x 35 x 1 mm , this can be found in shampoo bottles.
- Elastic cord (shock cord), diameter/size 2,5 mm, 3/32 inch or 2 mm, length: 8-25 cm ,

Step 1.
- Cut out the plastic piece and flatten it,
- print out the template SkottiRotta.pdf and cut out the one that fits your strap,
- tape the template onto the plastic piece.

Step 2.
Mark along the line with sharp pin and make the hole using a hole puncher. You can use a electric drill to make the hole also.

Step 3.

Remove the paper template and cut out the cord lock. Important : cut out the “cord holder hole” like shown in fig. A-C and make the opening/gap thin to start with, if the cord is difficult to remove make the opening wider in small steps.

Now it time to make the small elastic loop on lens caps.

Step 1.
Make two holes with a drill of the same diameter as the elastic cord.
( distance between the holes, center to center : 12 mm)

Step 2.

Attach a 8-9 cm long elastic cord like shown below. Then tie them up and you are done with it. Enjoy using them.

$6 Macro Tilt Lens without glue or duct tape

This guy bought a discarded slide projector for $6 at a recycling center. He then turn the projector lens into a tilt macro lens for his dSLR.

Any lens can be adapted as long as the distance from the back of the lens to the focal point (slide, film, or whatever it is projecting from or to…) is more than the distance from the flange (where the lens attaches) to the sensor. Below is the projector the guy got from the recycling center and he is going to use the lens and convert it into a macro lens for his dslr.

Some addition material needed to build this macro lens. You will need a length of hose and a body cap for your dSLR

This is how he get the focus length correct. Something to bear in mind do not put the ruler inside the dslr.

After getting the measurement correctly the next thing is to cut a hole on the lens cap. Use a hole saw and cut the hole slightly larger than the inside diameter of your hose.

This is how it look like after fully assembled and it is now ready to be attach onto the dslr.

Another picture of it being attach to dslr and a macro shot taken with it.

He do it by first removing the iPhone back casing. Then you need to get a spoil or not in use anymore CD player so that you can use the lenses inside for your iPhone. This is to magnify the iPhone lens aperture so as to minimize the vignette that is cause by the dslr lens. After that he wrapped a thin layer of putty around the edges of the stacked lenses to stick thin strips of paper around the edges of the lenses. This is done so that they can be assembled together and handled as a single unit

He made use of old end lens cap, and two pieces of two-inch PVC pipe connectors to make the lens adapter to hold the dslr lens. It was important that the connectors could be connected via a screw thread – this way we can move the whole SLR lens back and forth for secondary focusing.
