Slow - I completely understand where your coming from, This decision to buy sony was really hard for me because I am a Nikon guy!! Everyone has different ideas of a perfect camera and what brand name to use and I totally respect that. I wanted to kinda do some food for thought on what you said in your last post. Nikons holy trinity are all 2.8's 14-24 2.8, 24-70 2.8 and 70-200 2.8. In reality Sony is not any different with their lens except that the the 35 mm is a prime lens and is 2.8 vs 1.8 or 1.4, I used to use the 35 mm 1.8 nikon and honestly really never ever would I use 1.8. I would use 2.8 and usually higher because of the small DOF. Now this starts to make sense if you look at the sony 35mm starting at 2.8 as its supposed to be tack sharp at 2.8
I really feel that SONY is going to be big in this market and once they release more lenses I think folks will be really happy but, I also understand what you are saying. Personally if I did not sell my D700 I would not even consider getting another camera right now because the IQ on that camera was soooo top quality, it was fast and accurate. The best Nikon camera I have owned. Even compared to the D7100 I tested out I thought it was somewhat better in many ways.
But I sold it because it just was not fun lugging it around with all the other glass. When we would go on vacation I would be so tired and my back hurting I have a herniated L7 and L5 S1. I suppose I could have easily just kept it and got a point and shoot but, I know me no point and shoot would have ever compared and made me happy.
Now that I have been in the market and been able to play with different cameras, the features of the SONY's is just superior to NIKON. The Focus peaking, DMF, Eye AF, the EVF in these new SONY's is really close to looking through and optical VF and the fact that you can see your blur, exposure and iso right then and there and nail the shot before you take is in my book very very very cool. These are things now from trying and testing that I would WANT to have in any camera from this point on.
Now I am no SONY fan boy just very impressed with the IQ of these cameras and the features. I still am not sure if this camera either of the two a7 or a7r are really a replacement for a professional photographer. The fact that you can use adapters and use are your lenses with equal or better image quality now hhhmmmm thats quite interesting and maybe is a replacement However somewhere in the back of my mind I am not sure if I should have just stayed NIKON and waited this out until more direct fit SONY lenses are available and to see how things played out......
I can only hope that SONY will release some fantastic glass all I really need is a nice prime which I think the 55 1.8 zeiss will be fine and a nice ultra wide lens. All the other lenses beyond that I don't have a need for but maybe an 85mm other than that I would be set.
Things to think about and food for thought.
