iShoot IS-RT1 Tripod Mount Ring for AF-S 300mm F/4E PF ED VR and AF-S 70-200mm F/4G ED VR Lenses - Black

Value for money, well built, strong structure.

Thismis so much cheaper than competing products that my expectations were low.However I've been using it for over 6 months on my Nikon 300mm lens with no problems.I find that you need to loosen the nut quite a bit to rotate the lens, but other than that I'm barely aware that it's there in day to day shooting.

Bought a Nikon 70-200mm f/4 and noted no tripod ring so took a chance on this based on other reviews. Not disappointed as it fits great and seems very solid

Excellent product, really well made, finish suits the Nikon Lens and Camera. £150.00 less than the overpriced Nikon version. Grips the lens firmly, safely, without marking. Whole heartedly recommend this, you will not be disappointed. Fitted 70-200mm f4 VR and D810. Would have like to have given it 6 stars.

Very happy with this mount. Works perfect on the 80-200 f4 and Z6

There are a number of things going for this tripod mount. Firstly it is much cheaper than the Nikon version, it is quite well made and best of all it has an Arca-Swiss type foot, thus saving the need of another bracket if you use that type of quick release. However, I have also bought a second hand Nikon version and this has highlighted some important differences between the two products. I bought mine for less than a £100, so still expensive, but the Nikon version is a heavier moulding, the felt inner lining also goes to edges, unlike the iShoot, which is a narrow strip, which when worn might leave metal rubbing against the lens. There are small ridges on the Nikon inside which does allow smoother turning when changing from landscape to portrait. However, the differences so far don't amount to a deal breaker but the following difference does. The catch on the Nikon securing the lens is much more substantial with the iShoot catch being very thin at the bottom of the catch. My second hand Nikon is in very good condition with the only wear showing on that part of the catch, obvious really, as when the mount is in its loose position for turning the camera, it is going to take most of the weight. Therefore, I will keep the iShoot as a spare and not use it in its loose position as I wouldn't want to risk my £1400 pound lens on what appears to be a possible weakness in the iShoot design. If you intend only limited use I think the iShoot will do the job but perhaps not for extended use in its loose position. I have included three photos. The first shows the catch with the Nikon on the right and the second and third photos showing the felt, the third photo is the Nikon and you can clearly see the raised area which seems to help with smoother turning.

Nikon charge a preposterous sum of money for their own RT1 - about eight times as much as this. The Nikon is better made, but for the price this copy is excellent value.

I bought this for my Nikkor 80-200mm and it seems to work fine and probably just as well as the Nikon branded version but at half the price.

A construção é sólida pelo preço, o tamanho indicado está correto, apresenta velcro no interior do barril para não riscar as lentes e ao mesmo tempo rodar a lente suavemente para um micro ajuste perfeito. Apenas tive que usar uma tira de fita isuladora preta para um aperto mais forte já que não estou a usar este suporte para a Canon etc que mencionam na descrição

perfect voor de Nikon 300 F/4E PF, zit solide vast. en dat voor een fractie van de prijs van een originele Nikon.

Grazie al doppio passo presente sulla base ed il piede a coda di rondine idoneo per l’attacco arca swiss si monta su qualsiasi testa di treppiedi senza difficoltà. In questo è superiore anche all’originale che ha solo il passo standard. Soprattutto per chi ha teste arca swiss la differenza è sostanziale. La fattura è ottima, si fissa perfettamente al Nikon 70-200 f/4 permettendo la ripresa sia orizzontale che verticale. Vale tutti i soldi che costa e se lo raffrontiamo al costo del Nikon … non c’è corsa. Chiusura di sicurezza affidabile, l’obiettivo non rischia.

Ich hatte für mein AF-S 70-200/4G und das 300 PF eine Schelle eines Drittanbieters in Gebrauch, allerdings noch mit konventionellem Fuß in Kombination mit einer Arca-Platte. Die Schelle hatte meine Erwartungen nicht erfüllt, wurde dementsprechend nur zur AF-Feinjustage benutzt und bleb ansonsten im Schrank. Nach der ausgesprochen positiven Erfahrung mit einer Schelle dieses Anbieters dür das AF-S 200-500 kaufte ich dieses Exemplar für meine beiden anderen Objektive und bin damit total zufrieden.Die Passform ist sehr gut, d.h. Anbringen und Abnehmen klappt problemlos., weil die Feststellschraubne über einen Federmechanismus einrastet und anschließend angezogen und gelöst werden kann. Das Feststellen und Lösen erfolgt ebenfalls zuverlässig. Die Stellschraube läuft satt und spielfrei, das Objektiv wird auch mit kleinem Kraftaufwand zuverlässig arrettiert, ohne die Schraube "anknallen" zu müssen wie bei manch anderem Drittanbieter-Produkt. Bei gelöster Schraube ist das Objektiv leicht beweglich ohne in der Schelle zu wackeln. Auch abgesehen vom Arca-Anschluss finde ich, dass die Schelle besser ist als das Original. Hoffentlich gibt es von dem Anbieter bald einen Austauschfuß für das AF-S 500 PF :-)

Belle réalisation en métal très propre noir anodisé et très bien ajustée au Nikon 70-200/4 AFS VR.Possibilité de passer rapidement en mode portrait sans démontage, repère sur la bague.Simple, efficace et durable résument bien la bague i-Shoot is-RT-1, ravi de cet achat.
