Hi All

Im thinking of adding this lens to my arsenal so I don't always have to carry the 2.8. Due to the loss of speed, for stationary subjects only (obviously), Im interested in just how slow a shutter speed you can hand hold this for. Does anyone have any direct experience?

Thanks!
 
I have this lens.

How slow a shutter speed you can hand-hold depends on several factors, the main ones being:
  • Focal length. You can use a lower shutter speed at 24mm than at 70 mm.
  • How steady your hands are.
  • Your camera. With an APS-C sensor you also need to take the crop factor into account.
Better to bump up the ISO - again how much depends on your camera's handling of noise.

I have been down to 1/25th at 24 mm and the results seem sharp enough but ymmv.

yes of course, all of this goes without saying :)



What I was after was a subjective opinion on how good the IS is :)

It depends on the FL and how discriminating you want your images. If you are doing critical landscape work, I would err on the side of caution.

That said, I usually feel my shots at 1/10-1/15 in the wider FL range come out nice enough for me, and I often push down to 1/5 to 1/7 where I am dealing with pretty high ISOs. I do find that as I get slower than 1/10 to 1/15 that the sharpness takes a hit on many shots.

Here is one at taken at 1/10 with the 24-70F4.



 
I used to own the 24-70 f2.8 II, but sold it several months ago. Lately I picked up a 24-70 f4 IS and have been very pleased with its performance on my 6D bodies. I haven't done any scientific tests, but the AF speed seems very fast to me, so I don't think that will be an issue. I have also found the IS to work well, even at wide angle, e.g., shots taken at 1/15 or so are much sharper handheld with IS on.
