Less expensive to replace then your lens. You need one.

Fits perfect and is what I would recommend on your lens so you don't have to worry about the cap all the time. Plus this is way less expensive to replace then your lens.

You should pickup a lens hood on every lens you buy. It protects your lens and prevents lens flare, a must.

A great item to add to your lenses so you can take pictures of small rooms like a bathroom.  With each click you will be saving money by not buying that $600 normal wide angle lense.

I have enjoyed not having to exchange low to medium MM lens. I use One lens until I use my 150-500mm Sigma Lens.

I have had a pair of Oakleys for a couple years the lenses got scratched and the polarized coating was damaged. Bought these and replaced the lenses. Far cheaper than getting a new pair.  Now my glasses are like new again.

The lenses are easy to change you just have to be a patient and take a minute to really align them, once in, perfect!

This is a second, one. my original one cracked when the camera fell on the floor whilst in its case. There was no damage to the camera lens - exactly why i bought this filter

Saved our lens!  Don't buy this because it's a UV filter (although it works fine for that, too) - buy it because it can be the last point of protection for your expensive lens. Case in point: Our $2800 Canon 70-200 F2.8L IS lens.  Dropped it. Fell directly on the end of the lens. Filter was destroyed, but no damage to lens. The front lens glass would have shattered with this drop, but the Filter took the brunt of the abuse.

it's pretty cheap and it works. This will protect your expensive lenses and clear that it doesn't interfere your quality of your photos.. at least it's not noticeable...

same exact lens hood that originally comes with the 70-300 mm lens. identical replacement for the original. if you are looking for this, you probably already have one you broke. this is that exact same thing you broke.

Even if you don't buy this to use different filters, consider getting it and a 46mm UV filter just to protect your expensive lens at all times. If the lens cap gets knocked off, the worst that can happen is you get dust on your filter. If you're hard on your cameras, this is a must-have. [No I /can't/ justify the price for this small tube.]

You should have a filter on every lens you buy. Works just as expected. Protect your investment. This thing is great.

We recently dropped our nikon camera, resulting in this ring being cracked.  We called a couple of camera shops and they said that we they could not repair it but offered to sell us a new lens.  For the price I figured it was worth a try.  Found a great DIY video on youtube and made the repair myself.  The lens worked perfectly after I repaired it, and saved me a fortune on a new lens.  If you can use a screwdriver and have a steady hand then you can repair the lens yourself

I really needed this part to protect the motorized lens,  and finally bought it.  This only adds a little to the thickness,  but is much needed for protection.  This part is easy to install,  and is made of anodised aluminium.  A great addition to protect your investment.  When deciding on buying this part,  don't look at it as an expensive part,  look at it as an investment to keep your expensive camera working without malfunction.

Quality is excellent.
A must have to protect the lens from knocks and to prevent flare.
Price is reasonable compared to original.

A cheap fix to scratched lenses on your GoPro waterproof case, a constant problem.  Easy to replace.  Get two!

You know if you need this cap - you have a 35-135mm Canon lens and you lost your lens cap.  It's an exact replacement, functions same as the original, not expensive.  Do it.
