Image stabilization question
I didn't know where to post this and since I have been looking at 3rd party lenses I picked here. This may have been addressed before but I can't seem to find what I am looking for. So here goes.....Over, lets say the last 5 years, has or how much has image stabilization in lenses improved. I have seen reviews where there will be a comment like....so and so lens has better IS then another lens. Then I see lenses listed as having like VR2, etc. So, I was just curious about the difference in today's IS compared to what I have on my 5 year old lenses.
