Nice shots Norman.
Was it the 400 f/5.6 you were having problems with ?? What were they ??
Matt.
Thanks Mtn Breeze... This was the third time my lens and camera made it back to Canon Repair, once by themselves and twice together because of focus issues.. First time the lens went, the replaced the USM assembly, wasn't working correctly.. It took a month this time to get it back this time, instead of a week... The focus problems were happening intermittently... Here's what they said the last time..
Service details Camera: It was found that the adjustment of the part (what part?) was incorrect causing rear focus from time to time... The part was reworked.. All adjustments and corresponding testing have been completed to Canon factory standards...
Service details Lens: We have examined the product according to your request, causing rear focus from time to time.. Adjusted back focus with body, check all..
