Re: Reasons for buying a NEX-VG900 instead of an A99

I'll have to differ here as I've had precious few issues with lenses needing fine tuning in fact I can't think of any problems I had with A mount lenses. Yet both D7000's required AF fine tune for every single lens I put on it. With the D90's they had no AF tune so you were basically stuffed, that's why I sent it for service twice (first time front focus, second time back focus again) out of all 5 bodies none were what I consider to be at an acceptable level. And certainly not suitable for paid for work where the degree of focus errors is way too high. Slight errors in focus might not be an issue in the real world, all the Nikon's had quite a variation in focus in many cases to a shocking level (ie missing shots by feet and metres) Add to that the Nikon's almost never refused to lock (ie warn you if the contrast is too low to get accurate AF)
A57 no AF fine tune, but the 50mm f1.7 wide open nails it almost every time..it's in a completely different league to the Nikon's I've used a far superior more accurate AF. As much as I hate EVF's I hate out of focus shots even more.
There will always be the odd rogue lens, but IMO if you have to start using AF fine tune on lots of lenses and with hefty corrections, then there is something wrong with the calibration to start with. This seems all too common on Nikon bodies even the D800..kind of a DIY focus calibration which is not my idea of good.
I'd be fairly reluctant to spend £1500 on a camera that only has acceptable AF with one central AF point, but hey that's my take. I found all 39 AF points all quite hopeless in the 2 bodies I had. None of the settings helped much AF-C slightly improved, 3d tracking is only very useful in specific situations. I think I took over 1300 shots at a wedding with the D7000 (way over my normal number) and about 60% were binned due to poor focus. Out of the acceptable ones a good few had to go for some tweaking in focus magic. I just can't accept that level of poor focus, which is why I sent the D7k off again for service..and sold it.
I couldn't wait to get rid of it..I just need to get a refund off that one that went back to Amazon
