What's not to like??? Hello!
Clayton•November 16, 2017
So for $2.25 I am not quite sure what people expect. If this was a $75 product, sure give it something other than 5 stars. Yeah, it's cardboard people...what do you expect for $2.25? Of course, you have to fiddle with it to get it just right and put scotch tape on some spots to make sure sure everything is square. But once you do, it's great. I absolutely recommend this without any reservations. I'll get accomplished what I need to for $2.25 and everyone else can spend 25-75 times more and get the same result. You get two of them for $5.50...I am going to give the other one to a photographer friend.
Best Value for the Money

Great product for the price. Used them to AF fine tune 6 lenses on my D7200 and still have one chart left over. I can't see any reason to pick up a more expensive focusing chart when this one does the job just as well. I was able to fix the back focusing of my new 17-55mm f/2.8 so I'm very happy with the results. There aren't any instructions included, but Google "AF Fine Tune" and plenty of tutorials will come up if you own a Nikon camera. Matt Granger has a good one on his YouTube channel that explains the process.
Just OK IMO

It's OK. You need good lights surrounding the calibration papers to get better results. But, I found this calibration tool is hard to proceed the fine tuning when you only have a few ticks + and - from 0. I could do better lens adjustment and easier too by shooting my fence tips(or nails) outdoor at 30-45 degree in day time.
Big bang for your buck!

If you are a photographer of any kind, get a couple of these and calibrate auto focus on all your lenses. On my main workhose lens, the Canon 24-105 F4 L, this made a huge difference. Prior to this I didn't realize that the lens was front focusing and causing me to miss shots. It wasn't an issue at F8 or above, but was a big problem at F4 and this product fixed all of that. It's funny how such a modest investment could yield such big returns.
Works great once you sort it out

This definitely helped with my 70-200mm focusing. Now I can reliably get a sharp shot wide open! 4 stars because it doesn't fold very well - it required some tape to make it keep it's shape though that's a small price to pay for a dependable focus aid and once you build it, works as well if not better than much more expensive alternatives.
