Help! I can't remove the lens hood on my new 100-400 and am afraid of damaging the lens if I use more force. Is it possible the hood is jammed? It looks like it's properly aligned...

I had the same problem when I tried to get the hood off the brand new lens. I did have the button pushed and it took a bit of pressure to get it off. I sometimes had a similar problem with the 80-400 but def not as tight as the 100-400.

Thanks. I didn't see the release button. The Reference Manual wasn't shipped with the lens. Everything's fine now.

The release button seems to be common on a number of Z lenses. Overall I think it's an improvement - the hoods are in much less danger of falling off.

I’m finding, in general, that the lens hoods for the Z lenses don’t operate very smoothly or consistently.
Some are on the loose side, some are so tight I worry about damaging the lens, and some don’t even really lock.
It’s very strange.
My hunch is that there’s very little variation in both hood size (injection molded) and lens barrel diameter (some for of machining). So I’m surprised they don’t play better.

Just something to get used to, I guess.

I wonder if others are finding this as well.

Nope. Thus far my hoods fit, lock, and lock just fine.

I have this issue with the 500 PF periodically for unknown reasons. I push/hold the button and jiggle the hood and that seems to work. That said I much prefer this design given those without the lock which are prone coming of with any type of twisting bump or friction.

I had the same problem with the same lens. It is getting better now but in the beginning I needed really strong power for the removing...

Barry,
Thanks for the helpful tip.
It takes patience and finesse, it seems, to get this hood on and off. But your technique definitely works.
I guess I just need to make sure I’m never in a position where I need the lens quickly.

Now if I can just figure out why the photos are soft with this lens and the Z TC1.4.
I took a few shots at 1/1000 @ f/8 (3D AF) from a tripod w/VR off) - and they’re soft focus.
I looked at them in NX Studio to verify the location of the focus point and it’s on the subject (a woodpecker)
But the bird isn’t close to sharp. Took another half dozen shots - same result.
This is discouraging - no where close to the 200-500 (the lens I sold yesterday…)
Haven’t tried it without the TC yet - that’ll be the next test. I’m just too far away from the bird in this setup.

…and I had such high hopes after all I’ve read about this lens…

I've had that happen before. Take the time to do some thoughtful testing with targets that are not moving, then graduate to more complicated tests. 1/1000 second is relatively slow for a bird. Often they quiver or move faster than it looks. While 3D works, it is more likely to miss or choose a target other than the one intended, so be sure to test using Single and Dynamic - which are more precise.

Thanks for the reply Eric.
I’ll give all of that a try - I’m not ready to give up quite yet. : )

It’s doubly frustrating because two days ago I took these same photos from the same spot with the same tripod and same camera settings (shutter speed, 3D, etc.) - except with the 200-500. And those were razor sharp. So the current results are very disappointing.

Forgot to add, the woodpecker was on a suet feeder - not the most artistic shot, but just a test. So the bird wasn’t really moving much…

I’ve had such great success with the 70-200/Z TC1.4 combo, I this this would be a snap…

Later update - now I’m noticing the lens can’t focus inside (think of your living room) at night. Even at 200mm zoom, I can’t get focus. It just hunts. I tried both settings in d9: View Mode and nothing.

Keep in mind the camera needs contrast to find a subject and focus. Once focus is acquired, maintaining focus can be easier. Make sure your exposure is set properly - including raising the ISO if needed. Sometimes raising ISO seems to help focus.

If it is still really struggling with focus, switch to AFS, Single or Pinpoint, and Low Light AF. Low Light mode is quite good if needed - just slower to focus.

Thanks Eric.
In hindsight, I think I may have been asking too much of the camera at that point.
I'll have to try that scenario again.

I placed a dab of yellow puff paint on all the shade's release button.

Easy to see and feel due to the puff nature of the paint.
