Marumi 67mm DHG Circular Polarising Filter

Most folks run to Hoya for all their filters, nothing wrong there as the company makes some fine filters at various price points (avoid the super budget stuff though) But in this case it's worth looking at other makers too.Marumi are a make I've been using for a few years now, and I've been very pleased with their products overall.This Polariser isn't cheap, you can hit the usual auction site for bargains (some are ok, some are not) The DHG is the digital high grade range of filters (the super DHG has an additional coating on it to aid cleaning)At this price you start to get good quality, but without the B+W wallet busting price. This filter outperformed the B+W CPL filters on lenstip's testing, and most other makers too. In the real world it's well made, with a slim frame so vignetting is less of an issue on wider angle lenses.Rotating the filter is smooth and without any grinding, optical quality is very good with an excellent polarising effect on images.As a side note a CPL is useful for a few areas in photography- Removing reflections on non metallic objects, and for effect in Landscape photography (darkening of the sky and increasing contrast)I tend to use them mostly for removing reflections which can be useful for product photography or items in display glass, but the effect can also be handy for cutting out water reflections too. If it's not metal a CPL will kill reflections with ease.For scenic work a CPL can be very useful, however I'd resist the temptation to use one all the time, or to always use one "dialled up to the max". When you rotate the filter the effect of polarisation becomes stronger, but there are times when you might not want to use it at it's strongest. In short a very useful filter (I'd buy a step down ring for smaller filter sizes it can get expensive otherwise), though to be used when required and with some caution (with wider angle lenses you get edge darkening with a CPL this is the effect of polarisation not vignetting)It's also worth noting you do lose some light with a CPLThe Marumi is a good filter, well made and with good optics, there can be some very slight flare when used with strong light sources, though many rivals have a little here too. A fair price for a good product

Use it every time I shoot, would not be without it ANYWHERE. It has saved my valuable lens from desert sand blowing, corrosive seaspray, debris during storms or pollution in urban environments. A good investment for any photographer...pro or beginner.

On a sunny day a polarising filter is a must. This one is smooth to use and of good quality with good polarising effect.

A good brand that has lived up to its name.It is worth paying a little more for good quality.

does the biz,no complaints.

My second Marumi Polar. Perfect as always.

If you have to use a filter, pick good ones. This one is one of those, and doesn't seem to impact on auto systems (I've had a Tiffen that really mucked up AF). The Marumi brand is one I had to research a little before buying, having normally bought Hoya or B&W, but this has proved to be an excellent choice, with image quality unchanged, other than with the desired effect of the filter.If you want to know more, look up lenstip.com, where they have excellent test data for various filters.Overall, recommended for the price, but match it well to the quality of lens you have too.

This circular polarising filter is one of the best I have used. It is easy to adjust for maximum effect. It has enabled me to take some stunning pictures of cloud formations.
