The sample photos with the polarizer shown today was taken using the B+W 82mm XS-Pro Kaesemann Circular Polarizer with Multi-Resistant Nano Coating. First off, let me tell you why a circular polarizer is good. First of all, if you love landscape photos, you have to get one, a circular polarizer helps contrast the colors and deepen the blue sky. Using a circular polarizer can also help get rid of glare from water, glass, leaves (what I'm showing you today), etc... A polarizer will also protect your lens from the elements like fingerprints, scratches, and water. It is a good idea to use a filter. I have also read online that a filter saved his L model lens from a fall! Definitely worth the investment because $100 < $5,000. LOL
If you are serious about photography like me, I recommend you not get the cheap ones because they cause unwanted glares in your photos and the polarizing effect isn't good. The ones I have are a B+W 58mm Kaesemann Circular Polarizer and a B+W 82mm XS-Pro Kaesemann Circular Polarizer with Multi-Resistant Nano Coating. They are German made filters, and includes special nano-technology coating that causes water that collect on there to drip right off. There is also little vignetting at wider angles. However, this filter is pretty expensive, but most good ones are. The 58mm one cost me around $100 and the 82mm one cost me around $250 (still worth it for the great German optics).
If you don't know much about polarizers, you will find two types of polarizers. One type is the linear polarizer and one type is the circular polarizer. The linear polarizers will have a slightly better polarizing effect than circular polarizers, but will render your auto focus function useless as the polarizer will prevent the auto focus sensor from seeing light. Linear polarizers are usually cheaper than circular polarizers. Circular polarizers won't effect the auto focus sensor and is what most people use. Circular polarizers are more expensive.
The only down sides to using a circular polarizer (like with all filters) is that since filters is suppose to filter out the light, it will also slow down your shutter speed and the time of day it will work the test (due to the sun) is slightly limiting. If the shutter speed gets too slow, make sure you have your camera on a tripod.
Alright, let's move onto the sample photos I took. All these photos were taken on my road trip traveling from the SF Bay Area to Vancouver, BC, Canada. If you want to see my trip photos, you can do so here. Please note some of the "non-polarized" shots still had the polarizar on, but it was rotated to not have a polarizing effect on the image as taking off the filter is a bit of a hassle.
A non-polarized shot at Eureka, CA.
Here is a polarized shot. As you can see some of the glare from the water has been removed.
Here is a non-polarized shot from Wheeler, Oregon from the deck of the Wheeler On The Bay Lodge.
Here is a polarized shot. As you can see the glare from the window is minimized.
Here is a non-polarized shot from Government House in Victoria, BC, Canada.
Here is a polarized shot. As you can see the reflection from the glass is minimized.
This is all the sample photos I got. Remember the filters I have is a B+W 58mm Kaesemann Circular Polarizer and a B+W 82mm XS-Pro Kaesemann Circular Polarizer with Multi-Resistant Nano Coating. If you are going to buy it, please buy it through my link. :) I get referral money that way and you'll be supporting the costs of running this blog. Even if you don't, please click in to check it out. I understand this filter might be a bit expensive for a lot of people, there are cheaper filters out there, but I don't recommend those. Also, when purchasing, don't forget to check if you got the right size filter!
Thanks for looking at this demo. I hope you have enjoyed it. If you haven't seen my past sample photos taken with circular polarizers, you can do so here.
