New Lens Hood - Petal syle

Art Scott

Ok I have been making my own lens hood/shades for quite some time after the one that comes with the lens either get broken or is lost for some reason....I have been using either old step up filter rings or old collapseable lens hood that have tears for my ring and gluing a video cam rubber lens shade to the ring and it has worked well and I have never been a fan of the petal shades ahy who as they seem to only work in one position.......landscape......but a few dasy ago I ran into soem on Ebay that screw in and the shade is rotatable for both landscape and portrait positions......
Here is the link to the one I bought and it arrived today and I like it quite well.

I had one of those when I used to have my S3 and S5 cameras. They are indeed adjustable to whatever angle you want. Lets say the sun is about 2o'clock to the lens you can put the big part of the petal at said position.
Good stuff.

Be a little careful with vignetting using those "petal" hoods that rotate. The reason the manufacturer hoods don't rotate has to do with the rectangular shape of the imager. I agree that using full-frame lenses on a crop censor reduces the effect of the vignetting considerably.

PS, That should read "crop sensor" above. My typing sometimes exceeds my spelling.

It also allows one to use "not recommended" hoods as well.

For example, I have three lenses that are all 77mm filter sized with a common bayonet style hood attachment. I can use the hood designed for my EF-S 17-55 on my EF 24-105 without any vignetting, at any focal length. And, as long as I'm careful, I can also use the hood from my 24-105 on my EF-S 10-22. I have to be careful to pay attention to the selected focal length as this combination will start vignetting at about 12mm and get's worse as the focal length gets shorter.

What this really get's me is a more effective hood, better protection from sun induced flare as the hood is larger than that recommended by the manufacturer.

As a final note, I found out the hard way that, on the 17-55, you can't rotate the hood designed for that lens and expect to not suffer vignetting. At a wedding reception, the hood got bumped and I now have about a half-dozen shots with two very dark corners. Luckily, most of these were ones that would never have seen the light of day anyway and I was able to crop the vignetting out of the the one I really liked.
