About Hitech P 85mm

The Hitech 85mm PROSTOP 10 Stop (3.0) Filter is designed for use on long exposures. It is primarily used to control the image on longer exposures allowing use of much slower shutter speeds. The visible effects created by using longer exposures is the effect of motion blur on any movement within your pictures, such as clouds, waterfalls, seas and rivers. The PROSTOP filter is fitted with a foam gasket perimeter, which creates a seal between the filter holder and lens, thus reducing light spillage around the sides of the filter.

Less expensive alternative

I have the Cokin P series filter holder which I have used with other Cokin filters. Not planning on doing a lot of 10 stop ND work, I felt that this was a good entry purchase into the world of long exposures. Various reviews that I read indicated that one might experience different levels of difficulty bringing your image to proper color balance. So I was prepared for this problem. One strong advantage of the Hitech filter is that along its outer edges there is a sponge baffle which dampens light leak when attached to the Cokin filter holder. When I first experimented with using this filter I had all sorts of mixed lighting problems. For a while I thought I would have to send the filter back as I just couldn't get a good color adjustment on the resultant images. As I looked at my "procedure" a bit more closely I noticed that even though I was blocking light leak coming through the viewfinder I was not shielding the front element or resin filter to a maximum ability. I had been shooting in the shade but still there is an abundance of ambient light bouncing all about. So, at least the solution for me, is to use your hat or some shading element making sure that you "see" its shading difference. When you observe these practices then your image will come out "neutral" or be very easy to color correct via Lightroom, Photoshop, etc.

Blue tint, but does what you need

By

Product is a resin not a glass (high quality plastic). Works great for 30 second shutters in mid day sun. Main use for me is water blur and clouds. Must know how to use your white balance controls in camera and highly recommend shooting in RAW for greater white balance control as the filter does leave a heavy blue tint. However, can be fixed in post or with AWB in the camera

RICH S  Yes, the Yes, the Hitech 85mm P Series PROSTOP10 Stop Filter will fit inside the P Series Holder
Shopper  what case is included for this filter?
BRIAN R  The one I bought came with a leather like pouch that is cloth lined on the inside. Velcro hold it closed. It's a nice case. It's not padded though.
Brian R  Is this returnable?
JOSEPH R  Yes - I did as it was giving a strange blue color cast to my images. I have read this can happen and you can correct this issue in LR or PS by simply adjusting the color temp, however I did not want to deal with it. I have used the B&W 10 stop in the past and ordered it instead as I really liked it.
