Created separate thread for these charts to hit more people who might know how to read them. These are from a lens that is a total mystery to me and many other fellow pentaxians as the lens has no branding on it, yet performs seriously better than average.
here is a link to the thread with my attempt to identify the lens :
Please help to identify this 135mm f2.8 lens
I thought however, that would be worthwhile to actually ask others how to read these famous resolution charts we see all over the net. Called MTF - - no idea why, still a mystery to me. If someone could be kind enough and have a look at these shots below. Were they taken good enough to be a credible source of any resulting informations ? How you actually read these ?
Thanks in advance!
Ok, here are the charts - to examine please click on each image to see full photo.
Each photo is 100% uncropped and unmodified - only description has been added. Images where shoot JPG in camera.
Click on the photos if you want to see the full frame - here are only small portions of each shot!
2.8 4.0 5.6 8.0
I tried to take as accurately framed shoots as possible and I know that it is possible to actually somehow "read" these lines and marks - but I have no idea how. Please somehow comment .
Thanks
