Hey PF,
I bought a da 50-135 in November 2011 from BHphotovideo and within weeks its SDM failed. BHphoto were kind enough to swap it for another (NEW) lens and payed all postage fees so no complaints there.. However, the other day when I pulled out my Da 50-135 it wouldnt autofocus for the first 3-4 AF activations. After that initial refusal to autofocus it worked perfectly.
I have an extended warranty which was also purchased with the lens, I am now wondering if i should send it in for repair or checkup whilst under warranty? or perhaps I am just being pedantic should I hold onto it and see if it becomes more recurrent..
It hasnt failed me once in the field!
Any others experienced similar situations??
Cheers
Dvaughan
