calibration

50mm f/1.8 @ ISO 100, f/3.5, ss 1/60
{that is a very slow shutter-speed for me, typically I try to shoot at least at 1/250}

50mm f/1.8 @ ISO 100, f/4, ss 1/1250

50mm f/1.8 @ ISO 400, f/4, ss 1/125

I purchased my camera {D7000 bundle) two years ago on a Black Friday deal.  I used the stock zoom lens one time and knew it wasn't going to work for me so I purchased my first affordable prime lens {35mm f/1.8} a week or so later.  Shortly thereafter I purchased the 50mm f/1.8 and finally the 85mm f1.8.  Once I started using the 85mm I hardly touched the 35mm or the 50mm due to the lack of image sharpness that they would produce.  Once I started digging more into the issue I noticed that my camera lens was focusing just past my selected single focal point (for portraits, the closest eye).  I wasn't having this issue with the 85mm.  I knew that my lens or camera needed to be calibrated but I didn't want to spend the money to get it fixed as these aren't the most expensive lenses.  Little did I know I owned a camera that I could calibrate the camera to each lens myself!  So I read these fancy instructions how to calibrate here and low and behold I fixed my other two lenses back focusing problem.

I also did another test on each lens to identify their sharpest apertures.  I was quite shocked at what I found on the lack of sharpness around the corners and what I would consider acceptable.  You can read how to test for your lens sweet spot here.

Happy Monday!
