  • Replied in Not true
    I think it's covered in later responses by others, but my point was that for my usage envelope the 2.8 doesn't behave in the way that the f4 does. As I hopefully explained eventually I don't use ...
  • Yes, thanks for your considered response, unlike some...I went to the dealer to establish it's not a faulty lens and also saw that the Canon does the same. workaround is to re-zoom. all the best

    Maybe you're a Juan Kerr :-)

    Let me remind you again: 70-200 f4 and 70-200 f2.8II mounted on tripods and a nikon full-frame bodies. Make a composition using the zoom ring and then move the focus ring from 10ft to infinity. As ...

    Yes, maybe everyone in the camera dealer on Sunday had screwy eyes/brains....I'll defer to your clear superior knowledge on that :-)
  • Replied in Not true
    What is true is that if you focus much further away than the MFD, then there is noticeable zooming at all focal lengths on the 70-200 f4 that is not present on the 2.8....or are you saying that ...
  • Stacking is exactly as you say, fix the focal length and then focus from front to back without zooming. Our F4 friend changes the zooming a lot as you focus. Now, if people don't believe me that ...
  • Tends to be landscape details at longer focal lengths where even if you stop down it's very hard to get critical front to back sharpness. The last shot my flickr stream of the weathered fence... ...
  • I went to a dealer and tried another 70-200 f4, 70-200 f2.8II and the new 80-400, and a Canon 70-200f4L IS. The dealer's 70-200 f4 is identical to mine. He had never seen this effect before and was ...
  • I'm off to a Nikon dealer now. I expect to find that it's standard design, in which case it will have to go and I'll revert back to a 2.8II IIRC, most of the discussion around the 2.8II was when ...
  • You get same effect as me in your images. The fov has widened as you focus further away. Are you able to create a stacked image from these in PS?
  • But whatever the differences between the 2 lenses are, what I'm saying is that the f4 has an immediately noticeable effect when focusing that the 2.8 does not, at least for me. This is borne out ...
  • My example images clearly show the problem for this f4. It's a gross effect when you see it changing the image size in the viewfinder and it completely wrecks PS Stacking. If you never shoot stacks ...
  • Hi, Ok, so if I set the zoom ring to compose, say 135mm (happens at any focal length). If the closest part of the scene is at 5ft and the furthest part of the scene at 10ft then I might take 3 to 4 ...
  • Hi, no, I had the mk2. I have never seen anyone mention FB for any of the 70-200s at all focal lengths whereas this f4 is obviously shifting focal length throughout the range. I've shot hundreds of ...
  • Thanks Mike...this matches what I see. For tripod mounted work where you need to create stacks this is a real nuisance. I haven't tested how the stacking software copes yet.
  • Forgot to add that this occurs at all focal lengths
  • Created discussions 70-200 f4VR focus breathing?
    Hi, I just replaced a 70-200 f2.8 mkII for a 70-200f4 VR to save weight. What I'm seeing when I compose and then adjust focus is significant shift in focal length that I never saw on the 2.8 (or my ...
  • Calling Epson is a waste of time. They'll say "sorry, that's normal in order to keep the head in perfect order"...and our cash-flow high :-) Somewhere in one of my threads is a reply with a link to ...
