4.0 out of 5 stars Does a good job., August 13, 2013

This review is from: Datacolor SpyderLensCal SLC100 (Camera)
I knew my lenses were not focusing correctly and I tried the manual approach of printing out focus test charts from the web and trying to do the 45degree angle thing with a tripod, it didn't work as well. This takes all the hassle of the manual process and makes the calibration easier to accomplish.

I'd agree with a lot of the reviewers that this is an overpriced piece of kit for the what you get but I think in the long run it will pay for itself. The parts are a bit flimsy and the ruler arm needs to sit right with the notch holding up the vertical part. The bubble level helps keep things square and the metal threaded hole makes it easy to mount this on a light stand or small tripod.

Every lens I owned needed a bit of adjustment. It was easier using this tool for lenses with lower F-Stops (i.e. 1.4 and 2.8.) where the short in-focus range is more pronounced wide open. You'll need to calibrate twice for zoom lenses; once for the wide and then for the tele end of the focal range. My Canon 24-105 and 16-35 had micro-adjustment settings for both ends of the focal length.

I noticed that it was harder deciding which lines around the zero mark on the ruler were in focus for the higher F-Stop lenses. In reality it may not make a difference since the subject would have also been in focus.

Dropped a star due to the cost.

Hi Siva,

How did you make two adjustments (one for the wide and one for the tele end) with a zoom lens? I know I can make one adjustment only (either wide or tele end, NOT both). So I appreciate if you can share your insight of how to do two adjustments.

It depends on your camera body. My Canon EOS 60D did not support adjustment at all, while my 5D Mark III supports W/T adjustments per lens. Check you camera manual to see what you can do with yours.
