bought this for viewing the partial phase of the upcoming solar eclipse.obviously I have not used it for that yet. experimenting on the bright full sun it works great. the 1/100000 filtration calculates out to be very accurate. it's hard to say whether or not the image is sharp because the sun doesn't have a distinct edge. I'll have a better review in about 3 months, but you probably won't be in the market for it then.

There is not enough contrast for autofocus to work. Manual focus provides for a sharp photo.

Won't know until August, but it seems to fit the bill!

seems to be quality construction.

You need a tripod with this filter

This is a special filter for shooting the sun, which has special effect to withstand the light and heat from the sun, and can reduce the light volume to 1/100,000 in order to shoot the sun.
There is the case that you carry multiple standard ND filters and choose one of them, or stack them to realize desired ND value at the shooting site. This filter can reducelight intensity over a wide range from 1/2.5 to 1/500. Since the desired ND value can be adjusted by rotating the filter ring, there is no need to carry many ND filters with different densities. Despite of its double frame structure, it employs slim profile frame (thickness is 5.9mm without thread) to prevent vignetting.
Variable Range
For adjusting exposure time
The desired shutter speed can be adjusted without changing the aperture.
For adjusting aperture
The desired depth of field can be obtained by adjusting aperture without changing the shutter speed.
Effective for creating digital movie
Since the shutter speed is fixed for digital video camera (ex. 1/60sec., 1/50sec., 1/24sec., etc.), the light volume has to be controlled to adjust aperture for the desired depth of field. This filter is effective to obtain it at any values. This filter is useful for making fade out effect also.
[REMARK]
In the range of high density, the cross pattern image may happen depending on shooting condition.
