I wrote and published this short article / post originally way back in January this year, on the 29-01-2009 at 17:24 on my old blog ‘Paul Inglis Media Web Journal’ to be more precise. I am republishing it here because new XDCAM EX users, whether it be, the PMW-EX1 or the PMW-EX3 are unsure which filter fits under the hood of the camera and still performs well.
Please note that this isn’t a cure for the ‘infrared’ or ‘far red contamination’ that is frequently seen on dark fabrics, black in particular. This is simply a cheap filter that’ll protect the lens element. I will write an article / post about the ‘infrared’ or ‘far red contamination’ in due course.
Anyhow in my opinion I believe that protecting the element on the PMW-EX1 is far more crucial than the PMW-EX3, simply because it is built in. With the PMW-EX3 you could replace just the lens (which costs around £1,500 to 2,000), whereas the PMW-EX1 costs more than twice that.
Nonetheless, it would be best not to have to replace anything more than a cheap filter would be much more viable. A UV filter on the lens element will help protect it from scratches, dirt, grease, knocks, bangs along with all manner of things that can happen.
Hoya 77mm SHMC PRO1-D UV
The biggest problem most EX users have found is finding a filter that allows the lens hood to be reattached once the filter has been screwed on to the lens. Please note that the PMW-EX1, PMW-EX1R and the PMW-EX3 all have a 77mm thread, so bare that in mind when ordering your filter.
After trying a few brands I found the Hoya 77mm SHMC PRO1-D UV has a Low Profile Frame which is just 3mm thick will allow the lens hood to be reattached. Furthermore there is no vignetting on the super wide angle either.
As all users of the XDCAM EX family know that the CMOS sensors are highly susceptible to reflections and this stray light which can ruin the footage. However, by using the Hoya Digital Multi-Coated filter substantially reduces the appearance of lens flare and ghosting caused by reflections consequently giving a clearer image with greater contrast.
Happy shooting,
Paul
