Lens Focus Calibration Tool Alignment Ruler Folding Card(Pack of 2)...

So I bought this knowing that it had a really small 0 focus target, meaning that it only REALLY works well if you're really close to it, enough to where your entire center focus point on your camera can cover the focus target. And that is this products biggest downfall in my opinion. Other than that, it's great. Especially for the price. I mean, comparable focus tools are 12+ TIMES THE PRICE - some magical how. Idk how that's even possible for them to cost that much, I mean... they're all just plastic and paper o_o ANYWAY: Here's how I got around that and turned this thing into a very useful focus tool that works for ALL of my lenses, ranging from 14mm all the way up to 1,200mm!!! 1. Print out a lens focus target - just google image search "lens focus target" and you'll find a ton of them. Print any of them out but try to cover the entire paper. I like the ones that have lost of stuff on the target so there is a lot to focus on (see the pictures attached for the target I used). 2. Cut out that target to exclude any extra bits of blank paper. 3. Cut out a piece of cardboard that has a long "stem" at the bottom. Make sure that this "stem" fits into the hole in the paper focus calibration tool (see photos attached). You'll want it to be long enough to where you can tuck it into the hole and then fold it, so it can be taped to the inner base of the focus calibration tool. I included rulers in the picture so you can kind of get an idea of lengths. Make sure to leave one side empty! This way you can still see the "ruler" on at least one side of the focus calibration tool. 4. Stick your target onto the cardboard using tape, glue or basically anything that works (and is light in weight). 5. Slide the "stem" of the cardboard into the hole of the focus calibration tool and bend it in an "L" shape towards the bottom. Tape the borrom of the "L" shape of the cardboard to the inner base of the focus calibration tool and tape the upright part of the "L" shape to the "target" of the focus calibration tool (see photos of the inner part of the calibration tool. 6. MAKE SURE that the part of the cardboard with the large target on it is pointed straight up and roughly in line with the "0" point of the focus calibration tool. NOTE: Due to the thickness of the cardboard, the new, larger target will be slightly pushed forward. But for the most part, this is negligeable. Just keep it in mind. Especially if you're using thicker cardboard. That's it! Now you can get even 30-50' away from the focus calibration tool and STILL get a good idea of where your focus point is hitting thanks to the larger focusing target! :) Is this the absolute best focusing tool ever after the modifications? No... But it's inexpensive and it seems to work really well. One of my lenses in particular was way off, this helped me get my subjects in the peak focusing point very quickly :) Hope this helps others out there! If you found it helpful, click the "Yes" buttons where it says: "Was this review helpful to you?" If not, leave a comment explaining why and I'll try to make it better :) I'd like to help people out there in any way I can :D Other notes, possibly to manufacturer: I really think you could make this tool a lot better by making the target a lot larger. It seems like you could include a second hard piece of paper to attach to this tool OR even have the "cutout" use a larger piece of the tool itself. It seems like there's a lot of space you could work with to achieve that. Also wouldn't mind if the tool itself was a little larger.
