purchased a sigma 30mm f1.4 very sharp lens pero pag contrasty condition blown out yung highlight or white areas.
pati color white stuff blown out even with stepped down aperture. can this be corrected by calibrating?

calibration can only fix front/back focusing...

you can try bracketing feature of camera to increase dynamic range of photo (show details of highlights and shadows)

Hi! I bought sigma 24-70 from JT about 2 years ago. I was using D90 then and now D7000, do I need to have the lens calibrated? How would I know if if it needs calibration.

Yes free calibration as long as Philippine unit

Sir as per you said pano yung mga unit na galing sa mga online sellers tulad nila Jeptall, Onestop o DBgadgets sa inyo ba galing mga Sigma unit nila? If ever may warranty ba sila ng JT? Thanks in advance sir...

Bro, pag ganun, check mo muna with the seller kung JT warranty yung unit nila. Nung nag-inquire kasi ako before kay DBgadgets, grey unit daw yung sigma 10-20mm nya so automatic na walang jt warranty.

Hi JT, meron akong Sigma 70-300mm DG then yung problem niya yung kapag mag-AF tumutunog at minsan hindi na nag A-AF tumutunog nalang. parang may naiipit na wire or something.

makukuha kaya yun kapag cinalibrate? how much po ang damage ng paayos? ilang araw bago makuha yung item?

Thanks in advance!
more power to JT
