I have A700, using it for almost 3 years. I am quite happy with it except Focus accuracy. Even with my 70-200G and using central double cross AF point in AF-A or AF-S, I miss-focus in broad daylight(3 out of 10). This is worse with other lenses like 50 1.4 and 135 1.8. Using outer AF points is more prone to miss focus. Low light situation is pathetic, I can't use outer AF points with my 135 1.8 at all.
Also I find AF speed is sluggish in AF-C, unless I use SSM lens.
My daughter has turned 2 and if I need to capture right moments I need a reliable and fast AF. I understand no camera can give me 100% success rate, but A700 is definitely not up to that work.
I am thinking of upgrading to A900 or A77. I'd like to know your opinion about A900 and A77 AF system. How accurate is AF system and how fast. Has anyone upgraded from A700 to A900 or moved from A700 to A77?
I really don't care much about noise. I rarely shoot higher than 1600 and if I am printing real BIG, probably those are landscape shots taken at ISO 200.
I read many reviews about SLT vs SLR, I personally prefer SLR but AF accuracy and speed is more important to me.
I'll either move to A900 or A77 or if nothing works in Sony world, I'll be forced to move to other system, but that would be my last option.
Appreciate your help.
