Late Edit: A few notes added in a separate post in this thread:

Thought I’d share some feedback and thoughts on my just-received Zemlin hood for the Nikon Z 400mm f/4.5 lens. Karl Zemlin first began make lens hoods for order on January 2. For the 400/4.5 he offers three versions: a short one, one that is the same length as the stock Nikon hood and one that is 150% of the length of the stock hood (call it the long version) which is just a hair under 5” or 125mm long. See his web site for more info. The hood does not flare at the long end and is uniform in diameter. It’s about 5mm (or about 3/16”) smaller in diameter than the Nikon stock hood at the long end.

I bought the ‘long version’ which when mounted is a little less than 1.5 inches longer than the stock Nikon hood. While I live in Arizona, my favorite destination is coastal British Columbia, Canada where I join others on tours for marine wildlife and bear photography; we shoot rain or shine and shooting is the rain is commonplace. So, with that in mind and while using a Lenscoat Raincoat, the long version provides more protection overall and for the front element from the rain, snow, sand or whatever compared to the standard length hood. This is the purpose for my using the longer Zemlin hood.

I almost always shoot this lens handheld on my Z9 and so my Kirk LP-70 tripod foot is seldom attached. That said, for the information of those who usually keep a tripod foot attached you might find the first image below of how the hood long fits on the 400/4.5, especially in the reverse or storage position useful. Note the clearance between the hood and the foot. The long hood does fit in the reverse position with the Kirk or standard Nikon foot attached - my un-exact measurements of the clearance between the hood and the foot showed just a ‘hair’ over 1/4” for the Kirk foot and about 5/16” with the stock Nikon foot. Not sure about vertical clearance with an RRS or the Hejnar foot as I don’t have any experience with either of those. However, with the long hood you lose some of the “carrying handle” ability of the tripod foot with the long hood. Only room for two of my somewhat chubby fingers. You can remove the Kirk and the Nikon foot unlocking and sliding them forward as usual even with the Zemlin long hood in the reverse storage position. Possibly the size of the long hood stored in the reverse position or deployed position on the 400/4.5 may be an issue for those of you who use a “holster” type of waist-mounted lens bag, e.g. a Think Tank holster. YMMV.

Karl does not make a lens cap for the 400/4.5. So you’ll continue to use your Nikon cap. With the long hood you can still remount or remove your lens cap (even if you have big hands like I do). That said, as the long hood is deeper than the stock Nikon hood you might find that you need to be just a little bit more diligent to ensure the lens cap is securely attached when using the long hood in position as you have to stick your hand further into the hood opening. Need some finger dexterity. After some thought I concluded that given the extra protection afforded to me with the extra length from any environmental elements, I’d be less likely to feel compelled to remove/replace the lens cap as often during a shooting expedition so I consider this a minor issue.

Bottom line: the Zemlin hood is beautifully designed and made as his other hoods have proven to be. The fit is great and the attachment is quite sturdy. FYI, when you do install the Zemlin hood mounting ring, you cannot use the stock Nikon hood without removing the Zemlin mounting ring altogether - which would be a bit of a pain. So, take note of that. For anyone that buys a Zemiln hood for this lens, note the installation instructions for a bayonet hood mount, e.g. 400/4.5 (and I think the 500 PF too) is a little different than for the hoods on the bigger prime lenses.

A few notes about my installation and some time to play around with this new hood while I sucked on the provided “Smarties”: I weighed the Zemlin long hood (without the mount ring) and the stock Nikon hood. Interestedly, both weighed 131 grams on my postage meter even though the Zemlin hood that I bought is 150% longer. Hey Nikon: There’s a message there !!

Karl’s included instructions are very precise. That said, one thing that I struggled with and didn’t fully grasp at first was when I tried to install the mount ring to the front of the Nikon lens. He clearly states in his instructions that the lock ring mounts flush with the front of the lens. I was not sure what that meant since when I first loosened the mount ring screw and mounted the ring to the front of the lens there was a ‘natural’ stopping point that the ring ‘hits’ given the shape of the front part of the Nikon lens. The trick I finally figured out - once I examined more closely why I could not get the bayonet features to ‘meet’ and engage - was that I had not mounted ring far enough onto the front of the lens. What tripped me up was there’s a small section of the front of the 400/4.5 lens that rises upward (i.e., the lens barrel is ever so slightly larger in diameter) that if the mount ring has not been loosened enough one cannot get the ring to mount far enough onto the lens so that the front of the ring is flush with the front of the lens. The “Ah Ha” moment …. I had to loosen the mount ring screw a lot more so that at the gap in the ring where the screw is was about 3/8” or more. Then I could push the ring further onto the lens where it needed to be. Then shift (rotate) the ring around until you feel the mount ring and lens bayonet slots and tabs engage. Hold the ring in place and tighten the screw with the supplied wrench. See the image accompanying this post which shows what the mount ring and the front of the lens will look like when the mount ring has been properly installed.

If you’ve watched Karl’s video that details the installation of the mount rings for the hoods of the big prime lenses, e.g. the big Nikons, you’ll note how secure and how much force he exerts in order to lock them into place or to remove them from a lens. On the Nikon 400/4.5 the hood does not attach as tight as what you see in his video about the big primes due to the hood attachment point design of the lens. One mistake I made initially was that I had over-tightened the mount ring screw on the mounting ring (once the bayonets seated) which has the effect of making the mount ring just a tiny, tiny bit smaller in diameter (I mean a fraction of a millimeter). So the result was the the hood does not mount as tight as it could. So I backed off on the ring screw until the ring was just a tiny bit loose but then snugged it back up so it would not wiggle or move. Then hood was more secure. Bottom line: Don’t over-tighten the ring screw. I sure none of you will have any problems with the instructions as this ‘knucklehead’ did.

Was asked in a private message about the overall length of the Zemlin long hood on the Z 400/4.5 plus a Z TC1.4 on a Z9 - front of hood to the back of the Z9 (allowing for the eyepiece) is 17.5 inches or 44.5 cm. With the Z TC2.0, instead of the Z TC1.4, add just over another half inch or 1.25 cm. Camera angle appears to make tape measure not correctly placed, but it is aligned with the end of the hood and back of Z9 eyepiece.

I just finished hood designs for the Nikon Z 100-400 - there will be 60mm, 90mm, and 120mm lengths available. The Nikon HB-103 seems to have been designed as more of a fashion statement than a functional hood as I was able to go out longer than 120mm with no vignetting at any focal length. The petal-style design of the HB-103 is totally pointless for this lens.

Great news. I'll order one when your site reopens.

The listing isn't up yet. Planning to get product photos tonight. My site is closed for sales right now while I catch up on some stuff - the hood will be available when I go live again on the 30th. Thanks.
