If you shoot outdoors, you need this filter.

Assuming I have enough light, I always use a circular polarizer when shooting outdoors. I was considering purchasing the Sony DSC-RX100 M4 and before I actually bought it I did some research to see if there was a way to mount a CPF on it. I then discovered this terrific product. They kit includes 2 metal rings and a pouch to store the filter in. It's easy to install the ring. You just have to be careful to align the ring with the camera lens so it is perfectly centered.
The filter snaps on securely and stays in place. Even when taking the camera in and out of my pants pocket it didn't fall off. The quality of the glass appears to be very good, I don't see any imperfections. It's a simple and easy process to rotate the filter at the end of the lens to acquire the best angle.
The only thing I would change is the storage pouch. It's designed to clip on to your belt, or belt loop. It's kind of big for what it does and kind of flops around. I would have preferred a smaller plastic case that I could put in my pocket.
The attached picture is a jpeg straight from the camera using the filter. Got to love that deep blue sky.

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.]

This is a great filter, thank you. I'm a professional photographer specializing on commercial work.

Good circular polarizer reduces glare, helps color - probably not THE BEST but its great when used with precision by someone who know how. Doesn't just sit on the lens, you have to adjust it for your lighting conditions.

Well made construction, metal, not flimsy at all.

Toddler niece knocked over my camera while it was on a tripod. Luckily this filter did its job and saved my lens from breaking. Had the filter on my camera for close to 10 years. Rebought the same exact filter again just in case another accident happens.

Love this Lee filter foundation kit . It does take a bit of a learning curve to get the have of it , but if you calculate the times right during the day you can produce some imaging results with streaking clouds and smokey looking water etc...  This is a must have in all camera bags. I wish I would have of bought this a long time ago.

Saved my camera from a rock to the lens, exactly the reason I bought it. As a climber, buy this and slap a filter or two over the lens of your LX-5 and you have the best hiking camera on earth.

I jumped off the bergshrund and into a glacier just below the saddle of Challenger on Kit Carson Peak, and this kept all the ice/water and rocks from destroying the delicate collapsible lens. My entire torso slid past a rock on the way down with this around my neck, and thought I had broken the filter as I heard an impact on the glass, but I did no damage to the camera when I should have destroyed it. My lens would never survived the summer without this.

It turns a worrisome delicate camera into a holdable tank, and this is the most wonderful upgrade to remedy a constantly misplaced lens cap.

I wanted a filter that would protect my 18-200mm Nikon VR lens but not degrade it's quality. I put a cheap filter on it until I could find a good one. I had a lot of problems with light flares and sun spots on the cheaper filter. The Promaster Digital Protector filter does a much better job of dealing with these problems. If you lay it on a white piece of paper you can't really even see the glass in the filter. It's that clear, and you don't get the reflections of light on it. I'm thinking if you pay hundreds of dollars for a good quality lens you shouldn't degrade it by shooting through a cheap filter. This filter is made for Digital cameras and I've been very happy with it and the price is very reasonable.

In my experience Tiffen makes a very good filter and this one is no exception. Threads match nicely and the filter seats firmly yet is easily removed. The rotation of the filter is buttery smooth and stays put. The Tiffen adds a nice degree of polarization that gives colors a bit more saturation and contrast with a minor loss of overall transmission. If you're not shooting with a polarizing filter you probably don't realize just how much stray/reflected light is affecting your photo's. Once you see the difference a good filter like this can make you'll wonder why you didn't start using one sooner. Put your UV filter back in the bag and put something in front of your lens that will actually improve every shot. I've spent bigger money on other brands of filter (Hoya, B&W, et al) and I just don't see that money buying me a better filter. Maybe I'm missing something but, "the proof of the pudding is in the eating" and Tiffen filters do the job for me without breaking my budget.

This is likely one of the best UV Haze filters I've ever bought for a camera...  if not the most expensive of that type.  However, quality and precision do cost a bit more and when it comes to optical glass, you'll generally get what you pay for.

The application for this filter is to fit on the lens of a FujiFilm bridge camera and essentially provide protection from dust, fingerprints and other errant contaminants.

None of my older 35mm film camera filters are a 58mm size, so it was time to go shopping.  Had I seen the B+W clear protective filter before buying this one, I would have opted for it.  That said, I am very satisfied with the performance this filter provides.

It is definitely multi-coated glass as reflection and flare are virtually non-existent with this filter.  That just happens to be exactly what I was looking for!

Hard water is such a problem in our area and this filter really helps.

If you are thinking of only having one ND filter for making flowing water then I would say this should be it.

The quality is top notch for both the ring and the glass.  Overly large case but that's B+W and it's nice to have the extra padding.

To give you an idea, I tested this filter on a very sunny day during the brightest part of the day and got around 2 - 3 second shutter speeds at f22.  Add a Circular Polarizer filter and you get 6 - 10 second shutter speeds.  Perfect for those flowing waterfalls and streams.

I didn't notice any color cast and only a slight warm tone when used with a CPL.

I got this filter as a sort of poor man's astrophotography filter, since I live fairly close to a large city. It really does improve contrast on long-exposure night shots.

Best filters for landscape photography. Period. You'll need adapter rings and the Lee foundation kit to go with it.

I find it protects the lens well.  Sometimes can cause lens flare if you're not careful, but that's true of most filters.

I bought it mostly to protect the lens on my point-and-shoot.  It works well there and seems to perform ok as a UV filter.
