Do-it-yourself tilt-shift lens


The tilt-shift lens differs from a conventional lens in that it moves and allows you to get significantly more effective photos. Such lenses cost a lot of money and are not accessible to everyone. That is why we present to your attention a video review that will save a lot of money and make a tilt-shift lens from an ordinary lens using budget materials.

Let's start by watching the author’s footage.

What we need:
- ordinary lens;
- scissors;
- a small screwdriver;
- a bicycle camera.

We take a bicycle chamber, from which we need to cut a small piece.

The next step is to disassemble the lens. To do this, first of all, unscrew the bolts on the side of the lens. On the lens that the author uses, there are three of these bolts.


After unscrewing the bolts, the lens begins to rotate quietly. Remove the cover and unscrew the lens.


Next, remove the adapter. According to the author, the adapter may not be installed in the factory lens, so you may not need this step.


After that, three more bolts will become available, which also need to be unscrewed.


So, after the simple steps of disassembling the lens, you can go to the next step. At this stage, we need a lens, adapter, back and a piece of the bicycle chamber, which we cut off at the very beginning.

It is necessary to connect the lens to the back with a piece of the bicycle chamber. It should be noted that the elastic should not be worn completely, but on the narrow part of the lens.

You need to start from the second end of the rubber chamber and put on most of the rear lens element.

Turn the next end inwards by about one and a half centimeters. It is also possible to skip this step if the width of the lens part on which you want to put on the camera is wide enough. In the case of the author’s lens, this part is narrow, so he has to twist the elastic band so that it sits more tightly.


Press the lens inward and see the tilt-shift effect itself. The lens shifts and tilts in all directions.For the sake of example, we note that the cheapest tilt-shift lens in online stores costs about 9,000 rubles.

Here from GOST 27017-86 Fasteners. Terms and definitions (with Amendment N 1): "Slot of a fastener. - Deepening a special form at the end of the bolt head, screw or a screw, at the end of the set screw without a head, along the generatrix or at the end of the nut. "
The definitions of bolt and screw in this GOST are cloudy, which still causes holivar. But the above definition absolutely unambiguously interprets the possibility of a slot at the bolt.
Smart people who studied sopromat and DM say:
"The bolt and screw differ in the type of design load.
The bolt works (and is calculated) for TENSION and CUT. The screw works (and is calculated) for TENSION.
Hence their design features (sopromat):
The bolt has a seating surface with a diameter EQUAL or BIG of the thread diameter. The screw has either a full thread or a smooth surface with a diameter LESS than the thread diameter. "
According to GOST (I don’t remember the number now), a screw is what is screwed into the part, and a bolt is what is with a nut (or other similar part), that is, what is loose before the connection is tightened. And the head actually has nothing to do.
Why is it jarring me when the screws (what’s the screwdriver) are called bolts (what’s the key)?
Thanks! But is it possible to use Helios-44M?
