DIY Plastic lens-hood for Industar-69 28mm f2.8 Lens

Industar-69 28mm f2.8 lens is a tiny pancake lens. It's cute and very pocketable! The lens comes without any coating so it has less contrast than the coated lens. Using a lens-hood at times increases contrast so I've found a cheap way to make a lens hood for Industar-69 28mm f2.8 using plastic bottles!

Online, there are many ways people have made lens-hood for Industar-69 but mine is the cheapest way especially for people without much tools and materials at hand.

So it was a trial and error for me. Not yet perfect but it works well. You can make neater one than mine.

The materials I’ve used:

1. Three (3) empty bottles of 1/2 litre sprite (a kind of aerated drink). Any such bottles will do. I too three bottles for trial and testing and also making various sized lens-hood.
2. marker pen
3. bread knife/ blade/ or any sharp cutting tool
4. small scissor
5. Black enamel paint 
6. small flat paint brush

I've made a mark using the marker pens around the neck of the bottle by guess the diameter of the lens and sliced through it with a bread knife. You can find a better way than this or do a trial and error way like mine. The cut shouldn’t be bigger than the lens because then it will be too loose to fit on the body of the lens. The cut should be more or less same as the diameter of the lens.

Then, I've cut through the body of the bottle to make an appropriate sized lens hood.

Got the edges trimmed with a small scissor for a more neater looks

Three slanting small cuts towards the male side of the lens hood/ bottom of the lens hood were made so that it fits around the Industar-69. This way it holds the focus ring snugly and moves along the focus ring while focusing.  

Painted the lens hood black and let it dry. Viola! It's ready to be used.

 

I've done a before and after testing with the lens hood and the contrast changed dramatically adding to the overall sharpness of the picture.

RESULTS below: 

The photos effects are raw. No post processing done except resized for sharing and cropping the edges slightly to show the before-after using lens-hood difference better.

All the photos were shot at Manual mode, i-Enchance and at aperture f/2.8 wide.

After

The above photos of before-after lens-hood was taken against the strong sunlight and it is obvious that using lenshood improved the overall contrast of the photo.

After

The above before-after photos were taken in normal sunny circumstance and here too it shows that using lens-hood improves the contrast and minimizing glare to a certain extend.
