Just some food for thought...
My opinion is just that...an opinion...but here goes!
I have stated many times that my goal was always to have the 28/2, the 50/1.4, the 100/2.8 macro and the 200/2.8G.
I had all but the 200mm when I had a mental lapse and spent the big money on the Sony 70-200 SSM G. I have since sold the others.
Why? After all, there are tons of reviews saying that the zoom does not compare to the 200G. There are pics to prove it. There is a thread all about it again right now on the black forum.
I took a chance. I prefer primes. They are usually bettor corrected, have less CA and better bokeh. They are smaller and lighter. Yet I bought the big zoom.
I have used the 200HS G a few times. It is STUNNING!! Quite frankly, if I don't pixel peep, so is the zoom. The zoom is bigger, but it is nearly the same IQ at 200mm. However, the IQ of the SSM is even better at 70mm and better still at 135mm. I have a full range of focal lengths to choose from. It means less time changing lenses and less chance of a dusty sensor. This zoom is so good that I am actually looking at buying the 24-70 SSM Z. These two lenses plus perhaps a TC and maybe a replacement 50/1.4 (for portraits) will be my lens colllection.
This lens is worth the money, and the pics I have posted here show how good it looks at different focal lengths.
If you can afford one, I highly recommend it. It was a big stretch for my budget, but I am extremely happy with it.
