K-x problem with Tamron 18-250mm (A18)
Need help, recommendation and advice from experts:
Using fine with this Tamron lens for several months. Unfortunately, abnormal was found intermittently while travelling at Korea.
Symptom: AF mode indication was strangely/suddenly changed to MF while trying to take a picture, and aperture value was abnormally flashing at the display. Even though you can still press the shutter to take a picture, the image certainly was in bad condition. Sometimes, it'll back to normal within a short time period. The worst case was replaced with a fresh new battery. I am not quite sure whether this was a battery issue, lens problem or K-x trouble...Should I bring the lens to Tamron or calling help at Pentax? Pentax may not provide any warranty service since I was using a 3rd party lens.
Look forward to hear your reply. Thanks.
