What is the quality and sharpness of the images like in comparison to the 70-200 f2.8 and the 18-70, 75-300 kit lens?
Does the weight differ much from the 70-200 f2.8 lens?
The 70-200 from Sony weighs over 1300 grams, the 70-210 weighs just under 700. So yes, there's a difference. Remember, the 70-200mm F2.8G SSM is a professional piece of glass, this is/was much more consumer orientated. That's also why the difference in final quality between the 70-200mm and the 70-210/kitlenses will be significant.
You really shouldn't be comparing these lenses to the G glass from Sony, because they're on a whole different level. It would be like comparing a Ford car to a Bentley. Both can suit your need perfectly, but the differences between them are so huge, they can not really be compared.
That's what I think at least. I'm not saying (or typing) that any of these lenses are bad, not at all. However, they're not as good as G glass. Why else would that be so expensive?
