I know some will have a knee-jerk reaction to this but recently I have been shooting with my 50mm (no IS) and also turning off my IS on my 55-250, 17-55, 24-105 and here are the results I am seeing. When I am looking through the VF is the worst part of not having IS. My images are fine without IS if I get the shutter speed up to double the focal length.
IS makes looking through the VF WAY better but it's not doing as much for my images as I thought it was. I know it depends on if you shoot action or lanscapes but I do a bit of both.....and everything in between.
I am thinking about buying a 70-200 F/2.8L (non IS) and wondering if I will regret it. I don't think I will.......having the 55-250 to practice has been a help and having 2-3 stops of light with the 2.8 will make it even better. I don't think I need IS most of the time. It's nice....but isn't helping the IQ much.
Is this accurate? I'm asking you experienced photographers. Can I get by without IS and save myself hundreds.....maybe get another lens. maybe a 35mm F/2 with the extra money? What's your opinion on IS and IQ?
