GhettoCAL: A DIY Lens Calibration Tool for Microadjustment-Enabled DSLRs

GhettoCAL: A DIY Lens Calibration Tool for Microadjustment Enabled DSLRs ghettocal

It’s fairly well known that not all lenses are created equal. Put that in combination with manufacturing variables and lenses don’t always perfectly align with the camera mount. Generally the differences are minor and for the most part negligible, but I buy old Minolta lenses from eBay and I want to get the best bang for buck out of them.

I started making micro adjustments to my lens/camera combinations when I first got Sony’s a77, and have now micro adjusted all my lenses for the a99 and D3. After reading what the Internet had to offer regarding “micro adjustment” or the “fine tune” functions higher level DSLRs offer, I quickly printed off some charts similar to rulers and taped them to my wall to start making adjustments.

The Blazing Fast Autofocus Speed of the New Fujifilm X100s

When Fujifilm announced the X100s last week, it made the bold claim that the camera had the world’s fastest autofocus system among cameras of the same class. Sluggish autofocus was one of the big complaints owners of the X100 had, so for this latest refresh the company focused its attention on making the camera faster.

Want to see how fast the new AF is? We captured the short video above during a brief hands-on time we had with the camera. It doesn’t show an in-depth test or much variety in subject matter, but should offer a taste of what “world’s fastest AF” looks like in the flesh.

Ever since the Canon 1D X and 5D Mark III were released, photographers have been complaining about sometimes not being able to see the black AF points in the new 61-point system.
