is there such things as LENS needed CALIBRATION?
Got a sigma lens recently, but i realise the pix quality is not good.
diff lens sigma 18-125 and canon 50mm 1.8
same setting(all set to 50mm, same fstop speed same SETTINGs)
The pix taken by the sigma lens is always less appealing,
tone is not gradual and easily has hot spots, too orangy
Some told me...."your lens lousy"
"Maybe when this sigma lens is used for Canon 300D, it needs some calibration"
1)WHY THE CALIBRATION, IS THERE A NEED TO? any expert can give me word of ADVICE??
2) IS there a need to also update CANON 300D "latest version software UPDATES?"
