My Olympus EE-1 does not need any tools at all. It does have two adjustment wheels that may feel a little awkward until you get used to them. One moves the "dot" vertically and the other horizontally.

The first time you use it, it might might help to put it on a tripod and twist the wheels until both the screen and sight agree.

Once accustomed to the wheels, you can aim the dot at a distant object, take a picture and see if the object is high, low, left or right of center. The little adjustment wheels have "clicks". You'll learn how many clicks and which way to turn the knob.

Once you've trained your fingers you can skip the tripod. Shoot and adjust a couple times and it will be good until you take the sight off and put it in your bag.

If there is anything wrong with the design, it is that the adjustment knobs are easy to bump when attaching or removing the sight. The more expensive Nikon came later than the Olympus and may have a better adjustment system.

No contacts, circuitry etc so the mount is just a solid piece, the hot shoe is just a place to attach it. So it fits any camera brand hot shoe.

I adjust mine at about 60-70 feet (distance from my desk, through the sliding doors to a block wall in my yard) and then use "Kentucky windage" for other distances. hold high, hold low etc, I don't bother with readjustments every time. I also back off a little on the zoom lens to allow some cropping space for for poor aiming on my part, esp with a moving subject.
That adjustment knob bumping problem is why the sights made for guns either use allen wrenches to make adjustments or large over sized knobs that do NOT turn easily.

robertjerl - In the first photo, where did you get the vertical handle mounted to the tripod collar? Thanks.

I'm not Robert, but my guess is there are a lot of them. This is one: https://www.bhphotovideo.com/c/product/823279-REG/BARSKA_AF10926_ACCU_Grip_Camera_Pistol_Grip.html/?ap=y&gclid=Cj0KCQiAkfriBRD1ARIsAASKsQLEyCiQNx4WOY0IoJWq03cE0ExartAHm0F4VjmwcXlH8PEEz64FWZsaAinnEALw_wcB&lsft=BI%3A514&smp=Y

Bought the Olympus Stylus SP100EE a few years, ago, now - which has the dot sight built-in ….

And besides the "real" photo shops like "bsprague" posted they are all over Amazon and Ebay only two or three styles but a gazillion brand names and prices from under $10 to $30. I suspect there is one factory in China cranking out all of them with what ever name or color the buyer will pay for.

You could also buy a $5 weaver base, drill out a larger hole and mount the base to a tripod foot (1/4x20). Most dot sights come with split rings that will fit the weaver base (see Champion Shooters Supply). Dots have been around since the early 80s. Used on an a 22 High Standard for those indoor ranges that were dark. Later went to general use as did many others trying to prolong a competition career after the eyes started to age too much.

So, I tried it. The Nikon DF-M1. Yes it fits my camera just fine. Yes it calibrates easily. That's were the fun ends. The brim of my hat doesn't clear the high stack. Calibrate again.
Shot a couple of gulls. Practice Practice Practice.
Drive to a new location - check the calibration - got to calibrate again. Haul out the tripod, try again.
In the car, the camera won't sit comfortable on the floor and rolls over, knocking off the site.

It's simply a PIA with little to say that's positive. If I had one of those P1000's zoomed out to capture Tranquility base, perhaps it's the best site. On my D7500 shooting real birds - I'll stick with the view finder.

Thanks for your input.

I have to realign the Olympus when mounting it, but not had trouble with my hat or camera rollovers. Here is a shot I would never have managed without the dot sight.
