Top Rated Gear: Kirk Replacement Lens Collar for Nikon 300mm f/4 AF-S Lens (USA) Compatibility: Nikon Lens, Support Type: Replacement Foot

As with all Kirk products this collar is absolutely first rate.  Machining is spot on ans solid as a rock, fixing the glaring flaw in the 300 F4 AFS collar design.  Easy to install and retains all functionality.  Highly recommended.

What Nikon Should Supply as Stock

Extremely well designed 'cradle' (ie two saddles) design that holds the Nikkor 300mm f/4D Rock Steady. Something that was impossible to do for the stock Nikon mount (which I can flex between on thumb and forefinger indicating no possibility of stabilizing the lens when mounted to Mono/Tri-Pod.  The price may seem a bit steep but I assure you this is state of the art fabrication producing the last mount you'll ever need. 
Just budget for it and buy it with the lens if possible to save time or after the fact if the former isn't possible.
I rate this mount 11 out of 10 stars ... Perfection!!

A Must Have for the Nikkor 300mm f/4D AF-S

Wonderful fit and also becomes a useful carry handle for the lens + body. Works much better than the stock on my ball head than the stock which can slip out.

Very well made, worth the price.

This is a worthwhile upgrade on 2 counts - sturdier collar and built-in Arca-Swiss adapter. It is a mystery to me why OEM cannot do something so simple for a $ lens.

This is a worthwhile upgrade 

This tripod collar from Kirk is a must have for sharp photos on a tripod with this lens.
Nikon collar is not up to the task of supporting this lens steady.
Very happy with my purchase of the Kirk nc 300 Lens collar.

It's solid, smooth and works well. Nikon should have included a collar that was this good.

Perfect Replaced

The mount is very well made and even when I hand hold the lens, it provides a solid resting place in my palm. It's easier to remove than the Nikon version. I purchsed this used from Adorama and frankly couldn't find any evidence of use. I like the fact that it incorporates the Arca-Swiss dovetail, although it can also use the standard 1/4 20 tripod tread.
