My issues really are with the lenses or optics ... not the camera. I bought my KM AF 24-105mm f/3.5-4.5 "D" from B&H Video, from their "USED" department. I got a relative good price on it, so I made the move to acquire it. It is my own fault for trusting it to perform like a new one should. The thing about this issue is that with the quality of the A700, I almost know immediately whether these lenses are performing properly or not.
I had not gone through all the focus testing on most of my lenses, until recently ... and then they started "falling out." Back focusing primes, soft focusing 28-75, same with the 24-105. I won't even address the 28-300 ... even after adjustment, it is woeful. The 18-250 is a quantum leap over that utility lens. I highly recommend it as a "one lens solution."
The "film" glass has been pretty dismal, as far as returning sharp digital shots. It is obviously much older glass ... and I'm not expecting miracles from it, so over time I have replaced most of it. It really does not get much use. Sure, it'll serve the newbie who isn't too concerned about precision, yet. At this point, I'm a little further along with that ... and after experiencing what the CZ 135mm f/1.8 and the TAMRON 70-200mm f/2.8 lenses can turn out ... well, your tolerance begins to wane on the older glass results. Unfortunately, my current budget does not allow for more expansion, at this point. At $1500 per optic ... it gobbles up a wallet in short order.
I am going to heal back and watch the economy go through it gyrations ... and hopefully, on the other side, I can upgrade to the serious glass ... and end this constant struggle with having to get things adjusted right out of the factory (OOTB). The images do not lie ... they tell you the truth ... ugly or no.
AND about that secondary depot ... all I could get, at this point, was that it was a "SONY-Authorized Repair Facility." I will call, tomorrow, probe this question a bit further, if possible.
