AutoFocus Lens Calibration Tool Compatible With Most DSLR Cameras

Who knew that you could adjust your autofocus to be crisper? Not me until I read about it. The process takes some time to get set up but once you have done it to one lens you can get through the rest pretty quickly, unless you need to move either the cameral or pyramid to compensate for longer lenses.If you're not happy with what your autofocus shots look like I highly recommend this inexpensive do it yourself tuning tool. Don't forget to get a bubble level for your camera.

It’s my fault for not reading the full description, but this is a piece of card stock you fold into a pyramid. I thought it was solid. I’m not sure I’d have paid $20 for this if I had known. The description is accurate and the print on the item is clear, so this isn’t a critique, per se, but a more clear warning would be nice. There are other card stock lens alignment tools on the market for a quarter the cost and some solid plastic ones for only a few dollars more.

I was having problems getting sharp tack focus with my Nikon D800. Some of my lenses always appeared to back focus. I purchased this handy little tool and calibrated all of my lenses using it. BAM! Tack sharp focus every time! Every camera lens has some variations in focusing, this will help you to zero in on that focus and significantly improve your focus. Worth the money. My only complaint is that it was hard to find the instructional videos on how to use this and then I had to find the instructions for adjusting my Nikon on lens focus settings on my own by doing a web search.

I'm going to rate it as a 3 and that's most likely due to user error. I could not achieve focus probably because I don't know what I'm doing. I watched some videos on youtube to help me but I would much rather a professional to do this for me. My focus is really off on default settings but I feel like I was not getting any closer to achieving focus correctly. After I folded it, it wasn't completely flat so I don't know if that plays a part in it as well but it's not as easy as people say.I would also say it's too expensive for what it is made out of. Now again, maybe if I could do it, my tune would be a little different. LIke many have said though, it's really a cardboard piece of paper and you have to fold it to shape.

I was expecting a solid pyramid like as it shows in the photo, instead it was a thin piece of cardboard paper that had the pyramid printed out on that you’re supposed to fold by. For about $25 I do not think it’s worth it. If it was made with at least a thicker piece of cardboard or a flimsy plastic, I think it would be a better option, but for the amount you’re paying, and for what you getting, you could easily just print it out on a piece of paper and hope for the best.

This is a great product.Included are very easy setup instructions.Putting the tool together only takes moments.Setup takes a few minutes.Finding the settings in my older Nikon DSLR was the hardest part.I only have nikkor lens's and to my surprise did'nt need any tweeking.However may i suggest you get some sort of Hot Show Bubble Level!This will make the process more tolerable.I picked up the "Polaroid Hot Shoe Three Axis Triple Bubble"

I wish I'd read the reviews before purchasing. Had I, then I would not have expected a precision calibration tool made of - oh, I don't know - precise hard plastic. Imagine my sheer confusion and dismay when I opened the Amazon box to find the "pyramid," yet it was flat. And made out of bend-and-fold-tab cardstock. You know, the photographer cousin to Steak-n-Shake's kids' menu (fold tab A into slot 1, bend until B folds into C, and now you have a nifty car!).So okay, moving on from the cardstock material and the absurd price of $25 (they even printed on the bottom to recycle it instead of throwing it away. For $25, I'm going to hold on to it until it's yellowed and brittle and must be kept in a nitrogen sealed environment to slow decay), as other reviewers pointed out, due to the material and tab insertion and whatnot, it doesn't exactly sit flat. Or level. Or consistent. If a precision calibration tool is not precise, what good is it?If it were made of hard plastic, I think it would be a winner and I - along with several reviewers - wouldn't feel gipped. As it stands, $25 for an inprecise cardstock bend-and-fold pyramid leaves a bad taste in my mouth - and question over whether my lenses are actually calibrated correctly.

Worked great and the instructional videos are good. Only problem is site certificate was expired, but I had already watched the video tutorial.TIP: Proactively overfold the cardboard before inserting the tabs. This will allow the product to lay flatter.It took about 30 minutes to calibrate two lenses.
