Computer Watt Calculator

The 10 stop filter is simple to use with the long exposure calculator.

Photography in a dark room. Love the calculator being available at all times

This calculator is beautiful, stylish and perfect. Item exceeded my expectations. I would purchase again.

The battery is for an older calculator. Back of the calculator indicated a different battery. After opening the calculator took the old battery out and the new one from B&H in it's place. Simple fix.

its almost a mpc1000 inside a calculator, and the automatically chop input sound to the pads feature is insane

This camera is very well built as well as sturdy while at the same time being light in weight. I got great images on my first try. It comes with a simple calculator that gets you in the ballpark of exposure times. I am also enamored of how easy it is to pack and carry around.

I've been using this for work for a few months now and it's been working great. I set a programmable key for the calculator app which I use frequently. With use of 8 - 10 hours a day the batteries have not needed to be changed. The mechanical keys are much more accurate that the standard I've been used to using. Much easier to type on.

Was concerned about if it would range & input less than 29 yards to the ballistic calculator was pleasantly surprised when it registered @ 7yds does all it claims to

This is a fantastic sight, I like all the options that come in the package. I purchased the ranger calculator with it and they work perfectly together. Thanks for a well made product.

Most ND filters do not block IR at the level suggested by their rating so images are overexposed if you use an LE calculator. These Firecrest ND filters are great for long exposure IR shooting with the resulting exposures very near what the calculator suggests.
