Okay, So my 50 1.4 has never been real sharp below f/2.8 and I just feel it has had always had focus issues. So I send it to the Factory Service Center and they have it for 2 whole weeks, only to send it back and say there is nothing wrong w/ it. They did NOTHING to it but lube it and check it over. So it comes back to me and is still the same. THEN I buy the 105 DC f/2 lens and that thing straight out of the box is front focusing a lot-- the tuning in camera didn't even touch it. So I send that in. They've had it for 11 days. They tell me today it's shipping back to me and that there is nothing wrong w/ it I know this is exactly 45 degrees b/c of my manfrotto tripod. I'm not a beginner, I know how to use my camera. I've been doing this for 5 years now. I called a higher up at Nikon and they really could care less, obviously. They tell me I would have to send the 50 1.4 back to them and I just can't be w/ out that lens for another 2 weeks only to get it back and have them tell me the same thing. Also, regarding the 105, don't you think if you order a $1000 lens and pay for overnight shipping that you should be able to use it right away? Not send it away and wait another 2 weeks? What kind of QC is that? So if it comes back to me still not focusing right, it's been over 2 weeks, B&H won't take it back and I'm stuck w/ it.............. What kind of testing do they do? Do they do real life shooting or just tripod? Any advice?
