Not All Lens Filters Are The Same

Filter Comparison

The subject of using or not using protective lenses can invoke heated debates among photographers, with both sides often fiercely defending their choices. I am not going to debate whether it is right or wrong to use protective filters – that’s certainly a personal choice. I have been using them for a number of years now to protect my higher-end lenses and make it easier to clean lenses with recessed front elements (such as on Nikon 50mm f/1.4G / f/1.8G). Having had bad experience with purchasing a low-quality no-name brand filter when I just started photography (it was sold to me as a “must-have” at a local photo store), I learned what such a filter can do to my photos the hard way. Since then, I have only been purchasing multi-coated B+W filters that use high-quality Schott glass. I have been very happy with these filters and have been telling our readers to either use the best they can find, or not use filters at all.

Do Filters Affect the Resolution of Lenses?

Filters to Use or Not to Use

Just like the old “film vs digital” or the “Nikon vs Canon” debates, lens filters often create endless discussions on the Internet. Some people argue that one should never use protective filters, since it is another piece of glass in front of the lens that reduces resolution and emphasizes other optical problems such as ghosting / flare, while others argue that filters make it easier to protect the front element of the lens and make it easier to clean that element. I personally have been recommending use of protective filters for years, as long as they are of high quality. The filters that I have been using do not seem to affect the resolving power of lenses they are mounted on and mostly do not seem to heavily affect ghosting / flare either. Having spent the last couple of weeks in a lab testing many lenses, I wondered if I could actually measure the resolution of a lens with and without a filter. I recently purchased a used lens that came with a crappy plastic filter, so I decided to run two separate scenarios – one without a filter, one with a high quality B+W filter (more on B+W products below) and one with a cheap plastic filter. The results of the study came out very interesting!

Hitech Neutral Density Master Kit Review

Hitech Neutral Density Filter Kit

This is a review of the Hitech Neutral Density Master Kit, which contains a number of filters that I use with the Hitech Filter Holder for landscape photography. Since I personally prefer soft edge graduated neutral density filters over hard edge (doing mountain photography with hard edge can be problematic), I decided to go with the Soft Edge ND Kit instead of the Hard Edge ND Kit Density Kit. The nice thing about this particular master kit, is that it contains two sets of filters – one standard set of square ND filters (1, 2 and 3 stop) for slowing down the shutter speed when photographing moving water, waterfalls, etc., and one set of soft-edge GND filters (1, 2 and 3 stop) for those tricky high-contrast scenes during sunrise, sunset, etc. If you do not understand what any of this means, I highly recommend to read my article on Lens Filters, which explains all this in detail.

Hitech 100mm Modular Filter Holder Review

Hitech 100mm Modular Filter Holder

It is no secret that many landscape photographers, including myself, heavily rely on filters for field work. As I pointed out in my Landscape Photography Guide and Lens Filters Explained article, filters can be very helpful for, among other things, capturing more dynamic range in difficult lighting conditions, decreasing reflections and haze, enhancing colors and slowing down the shutter speed. I have been using a number of different filters and filter systems ever since I started photographing landscapes (more filter holder system reviews coming up soon), so when I found out that Hitech came out with a new filter system this year, I decided to give it a try.

Hitech Pro Stop 10 ND Filter Review

Hitech Prostop 10 Case

This is a quick review of the Hitech Pro Stop 10 ND Filter, designed to dramatically decrease the amount of light that enters a camera lens. Why and when would one need such a filter? With less light passing through the lens and reaching the film or digital sensor, slower shutter speeds/longer exposures have to be used, which ultimately blur any kind of motion. This neutral density filter is specifically designed for landscape photography: for photographing waterfalls, flowing rivers, moving clouds and other type of motion.

Hitech 105mm Circular Polarizer Review

Hitech 105mm Circular Polarizer

This is a quick review of the Hitech 105mm Circular Polarizer, designed to decrease reflections, reduce haze and saturate colors in photography (see our article on how to use a polarizing filter). The filter is specifically created for the Hitech Filter Holder system to be used with a 105mm plastic threaded ring that the polarizer mounts to and then both get attached to the filter holder.

Must-Have Filters for Landscape Photography

With Polarizer

While I was photographing the beautiful scenery of the Glacier National Park at sunrise, I realized that some filters are pretty much required to get good results when photographing landscapes. While many photographers think that some of the built-in tools in Lightroom and Photoshop can simulate filter behavior, making filters redundant in the digital age, some filters in fact can never be simulated in software, while others help in getting even better results in post-processing. If you do not know what filters are and what they are used for, I highly recommend reading my “lens filters explained” article before you continue to read this one.

Lens Filters Explained

Wide-angle lens polarization

Camera lens filters can serve different purposes in digital photography. They can be indispensable for capturing scenery in extremely difficult lighting conditions, they can enhance colors and reduce reflections or can simply protect lenses. Filters are widely used in photography and cinematography and while some only use filters in rare situations, others rely on filters for their everyday work. For example, landscape photographers heavily rely on various filters, while street and portrait photographers rarely get to use them. Since digital photography is all about the quality and intensity of light, lens filters are often necessary to modify the light before it enters the lens. Many photographers think that some of the built-in tools in Lightroom and Photoshop can simulate filter behavior, making filters redundant in the digital age. As I will demonstrate below, some filters in fact can never be simulated in software and some actually help in getting even better results during post-processing. In this article, I will talk about the different types of lens filters available, what they do, when and how to use them.
