Lens Calibration Microadjustment

Lens Calibration Microadjustment Workshop

Frustrated with slightly out of focus images? Come to our workshop, you can learn how to calibrate your lens and then bring your knowledge home to work on other lenses. If Amazon is out of stock, then PhotoWhoa has them too. We have two extra focus pyramids and participants can also share in case you do not have one or cannot get one in time.

Autofocus microadjustment is a procedure that allows a user to correct for small errors of front- or back-focusing.  Note that this adjustment is most noticeble will have the greatest benefit for lenses with fast apertures (f/2.8 and wider), because the thin depth of field at wide apertures makes even small focus errors more evident.

Make your photographs sharp! Give your lenses a new lease on life! The Focus Pyramid autofocus lens calibration tool makes it easy and affordable at half the size and cost of similar products!

• Canon 50D, 7D, 6D, 5DMkII, 5DMkIII, 1DMkIII, 1DMkIV, 1DsMkIII, 1DIV, 1Dx, 1Dc

• Nikon ( D7000, D7100, D300, D300s, D700, D800, D800E, D3, D3s, D3x, D4)

• Sony ( A850, A900, SLT-A77, A99, NEX-x with LA-EA2 )

• Olympus ( E-30, E-620, E-5 )
• Pentax ( K20D, K2000, K200D, K-5, 645D, K7D )

• Hasselblad ( H4D, H5D )
• Sigma USB Dock (any camera body)

• Some lenses ( i.e. Sigma 35mm f1.4 DG with USB dock) now allow for focus adjustments within the lens which provide fine-tuning with any cameras!

* Most modern DSLR camera bodies allow for AF Fine Tuning / AF Adjustment. Contact your camera manufacture if you’re uncertain your camera will allow for autofocus calibration and micro adjustment.

*** If your camera does not allow for Fine Tuning of its Autofocus System, don’t worry!

By using this product you will immediately know which of your lens front focus and which back focus and most importantly by how much. This provides you the information needed to make sharper photographs at the time of capture.(ie. When shooting portraiture, most agree focusing on the eyes is a good rule to follow but you may find that to obtain sharp, crystal clear, eyes may require you to focus on the persons ears or possibly tip of nose due to focusing problems found using this AF Lens Calibration Tool).

Everyone should calibrate their lens (either automatically if your camera has micro-adjustment or manually if not). At our last workshop we found that all of the participants' lenses needed adjusting -- and one person learned that his lens was NOT focusing at all; luckily he found out before he left for his big trip. Everyone should calibrate their lens!
We will reschedule this if bad weather occurs
