Description of 📷 DSLRKIT Lens Focus Calibration Tool: Precise Alignment Ruler for Accurate Results (Pack of 2)

This compact ruler allows you to determine if your lens is auto-focusing accurately as it should. It is an essential tool that is particularly useful when shooting with a shallow depth of field, where focusing should ideally be "spot on". You can use this ruler to determine how "off" the focusing is for a particular camera / lens combination and, on supported cameras, adjust the camera's auto-focus settings to resolve this. On Nikon cameras, this feature is known as "AF Fine Tune". On Canon and Sony cameras, it's known as "AF Micro Adjustment". Please refer to your camera's instructions manual to see if this feature is present. Size:28.1*18cm. Package Included: Lens Focus Calibration Card X 2.

Functionally good, but so weak

The item works but is so light that the wind blows it away when you use it to focus. You have to fix it. It's not quite what I expected. Probably overpaid! Not as much. Check the website and you can find deals where you can buy it cheaper.

Pros
  • On Nikon cameras, this feature is known as "AF Fine Tune". On Canon and Sony cameras, this is called "AF micro adjustment". Please check your camera manual to see if this feature is available.
Cons
  • Expensive

The target appears too small.

I am not a sizing specialist. The target seems too small for an accurate calibration, but I was able to find that my 100mm macro was very sharp, while my Tamron 24-70 was sharp at 70mm but soft at 24mm. I wouldn't feel safe doing a calibration for this purpose. I'll search for a bigger goal.

Pros
  • Size: 28.1 x 18 cm
Cons
  • Some errors

Good quality and price, but the target is too small for comfortable viewing in the frame after shooting.

The quality of this product and the price are excellent. Ultimately, however, the target is too small to accurately test lenses at the recommended distances of 10 to 25 focal lengths. I would have preferred a larger target to fill the frame more and zoom in less when viewing the image. Such a high magnification in the viewfinder or in the light room makes it difficult to read the imprint on the scale accurately. I sent the item back and printed something larger off the internet.

Pros
  • With this compact ruler you can determine whether your lens is autofocusing correctly. This is an important tool, particularly useful when shooting with shallow depth of field when the ideal focus should be "fine".
Cons
  • No performance
