    ND filter

    I used a B+W 10-stop ND filter on my a99 ZA 24-70 and recently picked up one for my A7R FE 24-70. I haven't done a ton of long exposure work in the past, but plan on doing more going forward. I've decided that I'm done with these screw-in filters. So, I'm thinking Lee Big Stopper, or similar type of arrangement. Anything you folks like that I should check out?

    Re: ND filter

    Lots of debate over what is a good ND filter when you get up to that high of a filter factor.

    Some have massive IR leakage which turns the shadows magenta, and makes it hard to color balance.

    Others appear to be less neutral, but once color balanced, seem to work better then the ones with the IR leakage.

    I don't believe that there is any real universalities that you can apply, as it doe appear to somewhat depend on the camera's sensitivity to IR.

    Look here:

    The JT Signature Edition Kit - Formatt-Hitech ProStop IRND filters BWVISION – Black and White fine art photography and long exposure photography

    for a comparison with the Lee product. Not saying the Hitech is better, but there is some information out there.

    Of course, for every opinion, you can find another that disagrees:

    I use both because I had the Lee when I owned a D800 and H4D/40. The Lee is easier with optical viewfinders. You just compose then slide into place, but the screw in filters work great with the A7/r because in most cases the image can be previewed in the EVF. Make sure to block the viewfinder before long exposures or you'll get color shifts and stray light.

    I'm just tired of the fiddly nature of the screw-in filters. Maybe it's just me, but I always have problems getting them 'started', and it gets on my nerves. After a little more research, I'm gonna give the Lee system a go and see how that works out.

    Re: ND filter

    I feel your pain LOL... I can not tell you how often I was cursing like a docker because of that circ.pol. screwed onto the 10ND did not come off again. Only with rubber gloves and the utmost patience I managed to get them unscrewed, eventually. These slimlines can be a pain in the butt, but hey they are top notch quality. No idea about the slot in filters and the quality of the glass.

    This advice is not applicable to mirrorless cams like the A-99 and A7R.

    Re: ND filter

    I've lately done many long exposure shots with A7R and lee filters on Canon lenses. Work a treat ! I staked them all the time, big stopper and one 0.6 or 0.9. Result is razor sharp, and WB is a little blueish but easily corrected in raw and Lightroom.
    I used screw filter years ago (BW ND1000) and lee filters are really, really better in the field, not even in the same league. Sure it has a cost, you have more stuff to carry and pay care to, but I would not use anything else !

    I've set C1 to manual BULB, so I frame and measure light in Av, switch to C1 and put filter holder and shoot with remote. Check this also : https://itunes.apple.com/fr/app/ndca...822835884?mt=8
