Does putting this on my lens eliminates the need of a lens hood in blocking unwanted light?

No - a lens hood eliminates flaring & is great protection for your front lense element.+

not really, but it will help some. It is more to get rid of reflected glare: this allows you to have very pretty blue skies, greener grass, whiter clouds,...., In general richer colors, ability to look into water that has reflected light (glare). In general I highly recommend in most outdoor situations (even if rainy or overcast) as glare often present and we don't see it is there until it is gone. Of note: you will loose about 1 to 2 f-stops, so in darker situations you may need to decrease shutter speed or open up by 1-2 f-stops.Hope it helps.

No. I normally shoot outdoors with a skylight filter (which I keep on at all times to protect my lens) and use the polarizing filter in highly light reflective situations ( e.g. Window, mirror, water, bright metal, etc.). The lens hood further reduces the flare.

No. Lens hoods block lens flare, which has nothing to do with the polarization of light.

The hood helps prevent flare by blocking light from cutting across the lens from the side. It doesn't actually replace a cap, but does put something in front of the lens and so protects against bumps. The cap won't fit on the hood - you'd need to find a larger one, but I'm not sure of the diameter. It's a bayonet hood though, so it's easy to take off and put on the lens cap when you put the camera back in your bag.

In addition to the other answers, using the filter holder function of this hood is essential, because the lens protrudes forward of it's surrounding ring when focussing at certain distances. If you screw the filter directly onto the camera, the lens impacts the filter, makes an ugly grinding noise, and the camera shuts down. Don't ask how I know this.

I'm not an expert, but to my knowledge, lens protection is main purpose. No added value to photo using clear glass. Since it's an extra layer of glass, there will be very slight impact on light transmission, but I certainly don't have a finely calibrated eye to see it with my camera and photo's I shoot. If you already have UV filter on your lens, you don't need to add NC.

The lens hood is to keep out unwanted light - say if it is really a bright sunny day out. Also for any dirt, rain or such from the end of the lens.

Robbie, did you get the filter? Will your lens cap and hood fit over it? I would like to leave it on all the time.

It does, yes. The cover ONLY fits if you have the hood on. For this lens, you'll basically always want to leave the hood on.

The hood is just out-of-frame, so I rarely find myself wanting to remove it, but yes, it's easily removeable by twisting it off. It's a feature Opteka added to the newer version of the lens, which is this one.

So... these filters serve two different purposes. The UV filter that I purchased is on my lens to protect the first element when I'm in situations that require me to be less than 100% diligent about where my lens is. A hood serves the same purpose so I supposed it is kinda redundant redundant... The Circular Polarizer is designed to reduce glare coming off of non-metallic surfaces. It can add "pop" to landscapes and cloud scapes much in the same way that polarized sunglasses do for your eyes. They do reduce the amount of light that makes it to your sensor and you'll need to take this into consideration. Hope that helps.

I find that the lens hood is very helpful in bright sunlight. The only hood that I have used is the one that comes with the lens.

No. I don't think so. I use a 49mm ND screw on filter and I cannot use the Lens Hood at the same time.

I'm using it on a Nikon zoom lens with 58mm threads, As the ad mentions, it does show slight vignette when extended, but I was able to remove some of the material on the hood that was causing the vignette with a file.

If lense hood has a circular flat outside edge then yes, if the outer edge is scalloped or uneven, then no.

This type of hood has an intermediate ring that screws into the filter thread and it has a lock ring to position the hood. If the filter fits, the hood fits. Whether the hood will or won't mask the corners depends on the focal length of the lens. I cannot help you more than that. For the price it's not a great risk! Good luck.

Thank you for the question. A hood cannot be attached if a lens cap is attached. Thank you for your consideration.

This filter screws into the inner threads on the nose of the lense. When in place it is stationary, flush with the edge of the lense and does not interfere with the lense hood on my XL2 in any way.

The only problem i have with it is when the lens is in full wide angle. Sometimes you will see the bottom of the lens hood so i take it off for those shots. Other than that it does keep your glass from banging into things while walking around.
