Good Evening,
Excuse my ignorance but where else to find considered opinions?
I have new Canon 80D bought from B&H on Amazon with several attachments. It came with 2 ultimax studio series uv filters by Japan Optics. It also came with efs 55-250 IS and efs 18-55 IS Kit lenses. Then I purchased with no research or much knowledge a couple of Bower 58mm tulip style hoods for the lenses.
Q1: is the tulip lense hood supposed to fit on the camera at a certain configuration angle. i.e. Do the leaves need to be at certain angle to the camera to perform it's intended purpose?
Q2: when searching online for a canon lense for the 55-250 I am only referenced to a cup style and not a tulip. Is this the proper style hood for that lense or does it matter?
Q3: other than for protecting the lense is the filter of lesser quality than others? I cannot find much info on this filter. Ultimax StudioSeries MC
Digital HD UV 58mm.

I know these questions are for kit lenses but generally some of the response will apply to better lenses that will come in time.
Thanx for considering a response.
Pat

Pat have you considered shooting a test chart (with mirror lockup and on a tripod) with and without the aforementioned filter?
The result therein will allow you to best evaluate what perceived acuity attenuation you filter has on the optic to which it is attached...
btw, this is what I have found to be the most valid approach to understanding how each filter actually alters the optical properties of the lenses which I use them on...

Lens Test Chart: http://www.graphics.cornell.edu/~westin/misc/ISO_12233-reschart.pdf

Food for thought: After several years of testing I no longer purchase "budget" filters... enough said...

As for your lens hood? Did it not come with instructions? Google the vendor and download their spec sheet, that would be my first choice.
That said, I always purchase lens hoods from the lens maker except for older "previously owned" lenses some of which only after market hoods are available... In those rare cases the after market hood functioned rather acceptably... and even mounted in reverse...

Hope this helps or is at least food for thought...
I wish you well on your journey Pat

Pat, those will work just fine. They are most likely indexed so they can only go one the correct way. If not, The larger petals of the hood are oriented towards the top and bottom with the camera in a normal "landscape" position. As for the filters, they are not a great quality filter. B+W is one of excellent quality, Hoya makes some also. They are worth the money.

I'm a little confused about where you purchased your gear . Did you buy from Amazon or B&H. If from Amazon, did your order actually say fulfilled by B&H? When you purchased the Bower hoods did they indicate they were made specifically for your lenses. Almost every lens takes a hood designed specifically for it. Which specific versions of the two lenses did you buy. There is the 55-250 IS and the 55-250 IS STM. The same for the 18-55mm lens. They are different designs so that a hood which works with the STM version will not fit the non STM version unless its a screw in. Its entirely possible the hoods you got are not designed to work with your lenses.

Purchasing anything with no knowledge or research is always risky

As UHH members have already said, lens hoods are specifically designed for the lens. The tulip style hood is designed to block light entering from outside of the frame without causing vignetting. I made this sketch for an article I put in my camera club's newletter.

The tulips on the left and right sides have a convex curvature. When you view the hood at an angle that corresponds to the field of view of the lens, they form a straight line.

Thanks,
The lense hoods were purchased from Best Buy. They don't fit as you describe. I will purchase canon hood and filter directly from canon. Your quick tutorial confirmed my suspicions and provided excellent information. I got a little hasty in my product purchase. Did not realize the hood was peculiar to the camera. As usual I am learning the hard way.
Thanx
Pat

Thanks for the help. Small mistakes can cause major headaches. In this case the camera purchased as a kit with attachments directly from B&H. The the hoods purchased separately from Best Buy and likely not correct. The lenses are STM. I was unaware that that small difference in data could cause another incorrect purchase. I was not using the STM in my search parameters for a hood and may very well have purchased an unusable product. Thank You. I must lean the hard way as per usual.

I wonder if B&H and Adorama sell through Amazon. I know they sell on ebay, but I never noticed them selling on Amazon. I wouldn't be surprised if they do. I see they sell Adorama-labeled products.

I buy the specific lens hood for the lens except when I need a rubber screw-on lens hood for aquarium or through the window photography

Q1: The extended part of the tulip goes on the top and bottom cause wides go wide left to right more than top to bottom. Understand?
Q2: I always use the lens hood that comes with the lens, however, the cup type works better for normal to long than for wides.
Q3: I never use skylight or UV filters, I always, always, have my lens hood attached for protection,besides it makes the lens look cool. I always have my rocket blaster with me to clean the lens. https://www.bhphotovideo.com/c/product/541904-REG/Giottos_AA1903_Rocket_Air_Blower.html?sts=pi

There is no such word as lense. The word is lens. The plural of lens is lenses. I realize you're a total newbie but it's good to learn the proper words.

Wise move. If you buy a clear glass (you do not need a UV filter) to keep the lens clean, make sure it is multi-coated, because even the OEM hood on a zoom lens is only effective at the wide end. There are some collapsible rubber hoods available that cover two or three focal lengths, but they’re not too convenient if you are zooming in and out much. I have one lens with a hood that travels with the zoom, maintaining maximum effectiveness at all focal lengths. It’s the only one of its type I know of. Edit: 28~50 f/3.5 Zoom-Nikkor AIS, HK-12 hood.

You are incorrect, it is a "Proper" term. Try Googling the word "Lense" and you will see it is an alternative spelling. See link below...

https://www.google.com/search?q=lense&oq=lense&aqs=chrome..69i57j69i60j69i65l2j69i61l2.1807j0j7&sourceid=chrome&ie=UTF-8

As for filters for "Protection", you will find many differing opinions on this. I am of the camp that doesn't use "protective" filters and haven't had an issue in over 45 years of shooting. Just use the search function and type in "Protective filters" and you will see the subject has been discussed ad infintum. Yes, I believe the filters you bought were the lower end but be careful as the better brand names of filters usually make different grades at different price points. The better ones aren't cheap either.
