B + W UV-Haze Protection Filter for Camera Lens – Ultra Slim Titan Mount (T-PRO), 010, HTC, 16 Layers Multi-Resistant and Nano Coating, Photography Filter, 62 mm

I wish I had just ordered this filter in the beginning. These are really expensive and cause you to pause when you need to outfit seven really expensive L series Canon lenses. This is not the place to try and save some money, especially if you do any professional shooting.I originally went with HOYA top of the line MRC filters which are a bit less expensive. Unfortunately, if they get dirty, it is almost impossible to get them clean again - especially if the dirt on the filter is oily like finger prints or skin oil. No matter which optical cleaning solution you use they will leave a very slight haze on the filter and this is after almost 20 minutes of cleaning. Not a good thing to happen during a shoot when the talent and crew are standing around waiting for you.I then tested the B+W non MRC filters, these are good as long as no light source is in the frame - you will have ghosting especially at night. For about 30 additional dollars you get the MRC version and this is at the top of the filter hierarchy. I had previously worked in Motion Pictures and the B+W coatings are far superior to all the different brands I have previously worked with doing film.Finally, I bit the bullet and ordered a bunch of the B+W MRC filters. They are perfect and clean very easily. I am slowly but surely replacing all my other filters with these exceptional filters. I also use one of their circular polarizers (had to sell a kid to afford it) but it is amazing and produces great results at the right angles.Summary: This is the top of the line absolute best filter for UV haze protection that is easy to clean, durable and very high quality construction. The only downside is they are very expensive.

Background and Context: I've never given haze filters much thought in the past and have used many Hoya and Tiffen filters (obviously I'm not a professional) on my lenses for the sole purpose of protection (mostly because I have a toddler). I needed a filter for my Canon 24-105 F4/L, and Amazon recommended this filter in the "frequently bought together" section of the product description. I wasn't too sure about spending the extra money on a "magic coating" for a utilitarian haze filter, but all I can say is that I am amazed with this thing and that it is definitely worth the money (see math below for justification)!Problem Statement: I waste a lot of time cleaning my lenses/haze filters (you would too if you had a toddler)- and I still can't get them crystal clear. I also need a filter that won't distort my lens, and most of all, i need something to protect my lens from damage.Math and "Business Case": Assume you have to clean your lens once a week and it takes you 10 minutes each session (you are very thorough) on your uncoated filter. That's roughly 40 minutes a month which equates to 8 hours a year. If you paid someone at minimum wage ($8.25 if you lived in Illinois)to clean your lens, that would be ~$66.00 a year. Then let's assume you will spend 1 minute every two weeks wiping off your B+W filter- using the same calculations, your cost to clean that would be $3.30 a year. So your hypothetical potential labor savings would be about ~$62/year (assuming a non-unionized workforce)- or roughly the cost of the filter at today's amazon price. If you are looking to purchase this filter, most likely you make more than minimum wage; therefore if your time is money- this filter is definitely worth the time it gives you to do other things (such as take pictures or watching prime time network television).Evidence: The "aha moment" occurred when I took my camera to a water park for my son's birthday party; and as kids will do, they started splashing and shooting water guns at me. When I went to wipe off the lens, I was amazed that the water had actually beaded off and the filter remained relatively crystal clear- i didn't have to do anything. This never happens with my other filters as similar events would result in a long session with lens wipes/solutions, microfiber cloths, and a blower (and the filter still wouldn't be crystal clear).More Evidence: In addition, I am lazy with my cameras and the lens caps are rarely on. I just took a look at my camera and the filter is still crystal clear with no dust or smudges. I hate to sound like an infomercial but this is really amazing!OK, I've spent way too much time discussing a circular piece of glass.Bottom Line: If you hate spending a lot of time cleaning your lenses and you perceive your time as valuable, buy this filter!Cliff Notes:Pros: Crystal clear, solid quality (made in Germany like Sham Wows), and the coating really works. Will save you time.Cons: Pricier than other Haze Filters

A filter is a filter is a filter.....NOT!!!!!!! I have been a photography enthusiast for some 45+ years. During that time I have used mostly Hoya and Tiffen filters with a couple of other brands occasionally.......I have tried to stay away from what I thought were the el cheapo filters thinking I was buying good ones. But all that changed TODAY!!!!!I had just recently bought a new Nikon zoom and decided that with a nice zoom like this one (instead of the generic brand lens) that I would actually splurge on what I thought was an overkill filter. I had seen reviews on the B+W but figured it was simply hype. The lens arrived Saturday and the B+W filter showed up today.The first thing I noticed about the B+W was the weight........this filter easily weighs twice what the others do. There is no mistaking that the entire mount is high quality metal. Impressive at first sight. Then I held it up to catch the mirrored reflection of a lamp next to my recliner, expecting to see the reflection of the lamp. It was not to be so...........instead of the single reflection on the front surface of the filter, I saw the multi colored texture of the filter with NO solid reflection of the lamp...............WOW..............I then proceeded to mount the filter on my lens and it is absolutely unbelievable. There is no reflection from the front of the lens with the filter mounted.Without a doubt, this is the best filter I have ever bought. It made a believer out of me and I will never again erroneously think that a filter is just a piece of glass and as long as it is coated it will be okay.............I learned my lesson. So much in fact, that I just ordered another one just like it for another lens that I just put one of the other brands on a month ago...............In summary..........there are filters, and there are filters............And then there are B+W filters..............and there is no comparison. This is the real McCoy and I will NEVER settle for a cheapo filter on a nice lens again. If you have the mindset I did originally, just try one of these and you will be amazed as well...............Easily, the best filter I have ever seen. Pricey compared to the others.......but worth it.
