Well now that you've made the camera hood now you need some camera equipment! Haha. I got a pretty cheap but very sturdy camera shoulder support from this place:http://www.habbycam.com/category_s/43.htm?searching=Y&sort=5&cat=43&show=10&page=1
The basic idea is good but it must be a screw-in type. Maybe I should use a filter and take out the glass?
What intrusion are you protecting the lens against? dust? rain? sunlight? other?
There are commercial solutions that won't endanger your brand new lens like a DIY solution might.
Any photography shop can show you their products and catalogues of products that will work but that must be ordered (as will the net)
In the link I specified my efforts to buy one. They failed as it eventually turned out that Mamiya never made a lens hood for this lens. I want to protect against sun and against a fall to the ground. Over the night I thought about it and realized that I can make one from a Canon hood I have available and a filter, which I'll remove the glass from. Now my only problem is how to attach both in a good and firm way.
ah...my apologies...i read the link but missed that reference.
You *may be able to find an adapter ring that will reduce your efforts some, although I can't say for sure, just trying to point the way...
I finally bought a generic lens hood, made of metal and screws in. I wonder what it will be like.
Find a styrofoam cup the right size, cut a hole for the lens to fit in. Then paint the inside black with poster paint not spray paint. Spray paint will dissolve styrofoam.
Styrofoam is way too fragile. If I am to make something then I want to make it from hard plastic. General shape should be something like http://www.adorama.com/MYLH35AF.html?searchinfo=mamiya+35+3.5+lens+hood
That lens hood used to keep extrainous light from entering a wide angle lens and spoiling a photo. It provides almost no protection for the lens.
What exactly is it that you are trying to do?
I'm trying to make a DIY lens hood that will protect both from sun (flare) and an accidental fall. That is why I prefer hard material like hard plastic.
