Calibration Lesson (Explored)

Those Flickr friends who have followed me for a while will know my love of my Tamron 150-600mm lens. Sometime ago I did a manual fine tuning of my lenses, which improved sharpness considerably. A friend told me that manual calibration of this sort, whilst helpful, was no substitute for proper, software controlled calibration, but I always balked at the cost of around £70 for FoCal, to which I had been recommended. However, I bit the bullet at the weekend and bought it and after following the programme I have now calibrated all my lenses to my camera body. The results have somewhat surprised me, as indicated by this "snap" of the goldfinches, through glass from an upstairs window in bright, harsh sunlight at around 14.15hrs this afternoon. Not a time when I would expect to get optimum results. The sharpness for this shot, based on the FoCal recommendations is better than anything else I have achieved, irrespective of the fact it is through double glazing (I was focused on the centre goldfinch).

 

Have any other of my Flickr friends calibrated in this way and if so what were your experiences? I should love to know.

 

I now want to try all my other, similarly calibrated, lenses in the field!
