Moose Peterson. You always have the best Nikon reviews.. Waiting for them to send you a 800pf..

Great review, thank you.

Moose, I loved the video. I absolutely agree that this lens/camera combination is outstanding. Great wildlife and auto racing performance. I finally received the 1.4 thanks to NPS and really look forward to working with it. Thanks for the video!

AWESOME AWESOME AWESOME VIDEO .... THANKYOU❤❤❤

Sand dipper photos are sooo good!!

Brilliant explanation, best review Ive seen towards any lens.... Thank you :) i got this lens for christmas yet to try it out , am also on Z9 :) can't wait to try it out :)

This was very interesting to me in that I do a lot of walk around bird photography. I have been looking for a Z-mount lens to replace the 500 pf with my Z 9. Thank you for sharing your experience.

Brilliant explanation brother 👍

Great review

Thanks for your summary review of the 400mm f/4.5 S line Z lens. Enjoyed your straight forward responses of "It doesn't matter what I would pick, it matters what you need to tell your story". Well said, but rarely said. Have to say, I'm a bit surprised that there is no AF speed or IQ fall off with the Z TCs (even if it is small). The lack of weight with this lens (given the quality of the IQ) is clearly the standout if you do not need the flexibility of a zoom that covers the same range. I have heard (not used the lens yet) that the out of focus transitions are generally more pleasing than the 500mm PF. Your thoughts?

Good video, I love your work, please post some shots when you do these types of videos

I am trying to decide between the Z 100-400 and the 400 4.5. I have a Z9 (which is insane) and need a good birding/wildlife lens. As always, this helps a great deal Moose. Thanks!

What was the foot replacement and flash bracket you showed? Thanks so much for all your instruction over the years.

Thank you for the fantastic review Moose, I have been a fan of your work for a long time. May I know where to get the flash bracket you showed during the video? Greetings from Brazil

I love that black lens cover! Any chance I can find out the brand or where you purchased? Thanks

Nice story about 400f4.5! I'm wondering, what lens protection is on it, would you share the link, please, thanks?

What replacement shoe do you have on that lens

Thank's a lot Moose for this enthusiastic presentation of this remarkable glass! What is your judgement by comparing it with the Z 100-400 S which is highly praised for its versatility - what is the difference in image quality and background blur at 400mm? I will have to decide between these two lenses for wildlife ....

Best lens ever

Cheers Moose, like yer plain English, tell it how it is approach. All m gear is F mount, this may be the decider I was looking for.👍

How is the 400mm f4.5S compare to the Z70-200 with 2X? Thanks Moose!

Does the lens fit very loose on your Z9? Mine had alot of movement, even a tiny bit of non rotational movement

Which teleconverter would be your first choice for this lens 1.4 or 2x ?

I had to decide on 500pf and this, on a Z6II/D850, so it was a no brainer, 500pf coming, 200-500 retired, order 180-600 cancelled due to back order uk backlog, it won’t be here anytime soon.

I see in the video now RRS

I have a Z9. Would you take the 400 4,5 or a 500/4 fl?

Do you find the 400 better than your fab 100-400S

👍🏾🙏🏾

Why they never came back with a 400mm f 3.5 is a damn shame. That lens fabulous in it's day and a great cheaper alternative to the 2.8.

Great video Moose. For sports and aircraft (often very similar) would you choose this lens over the 100-400 z mount?

Thanks for a real (non-influencer hyped) view. Sitting on the wall waiting for the Nikkor Z 200-600mm and I may have to get the 400mm too...🦘

Yep, that's a list that on my "want" list, but not my "need" list. I'm afraid if I buy one then I'll get the Z9 as well - nice camera, but it doesn't give me anything my Z 7 doesn't already have. I do landscape and some travel. No interest in either sports or critters.

My personal thought is Sony sensors are currently the best, they are used in Z9 and a wide range of products from across the world like smartphones, dash cameras, movie cameras etc. But I think with the history behind Nikon being a dedicated camera and optical brand they have the upper hand in the things that give the best experience such as grip and button design and lenses. I'm really liking what Nikon are currently doing with their Z mount lenses and I know I would own at least 4 lenses from nikon, like the 800mm F6.3 and the 400mm 4.5, but currently with Sony I have 2 lenses, the 200-600mm lens which im really happy with and a 24-105mm which is not very inspirational and I feel my options are limited.

F4.5......? $ 3200??
