Mcoplus EXT-Z-M, Macro Extension Tube Nikon Z Autofocus AF Lens Mount Adapter voor Nikon Z-Mount Z6 Z7 Camera Mirrorless Body voor Extreme Close-up Fotgrafie, Venidice Doek (12mm+20mm)

Marche parfaitement avec ma Nikon Z6 + 24-70mm /4S!

Sono di discreta fattura, e si adattano perfettamente alla fotocamera Nikon Z, preservando la possibilità di messa a fuoco.Non sono fornite istruzioni o specifiche tecniche di alcun genere.Ho provato in particolare il tubo da 11 mm, che è quello che ingrandisce di meno.Funziona bene, a parte l'onere di inserire un tubo fra macchina e obiettivo; ovviamente con questi tubi la distanza massima di messa a fuoco è molto piccola, ed il range di profondità di campo diventa limitato.Sono pervenute senza problemi come da tempi di consegna previsti.

I’m giving this a 5-star rating because it would be unfair to give it anything less. The rings are well made, lightweight, fit perfectly and match the Z-series beautifully. However, there are some caveats, especially in my case. First, I’m relatively new to photography and I’ve never used extension tubes before. So, I naively assumed they just added focal length to the lens. I now know that they don’t and only focus (manual or auto) at macro distances – about 12-18” away from the subject and if you are using a zoom, at the maximum focal length of the lens. There is no focus at all (just a blur) outside of this range. I usually shoot bugs, insects, flowers, etc and with my previous Nikon 750 and Sigma 105 macro, I could flip a switch on the barrel and change the focus range if I didn’t want to scare away my target. I generally only use autofocus to get within a rough range and then move myself slightly to really nail the focus (and then burst shoot to make sure). However, now as I can’t see anything but blur until I get to within 12-18” I’ve no idea how I can use the tubes and get so close to my subjects, especially if they are moving.Also, my 24-70 f4 focuses from this distance and because it’s not losing a couple of stops of light, I can get better depth of field and faster shutter speeds. In my case this important as I usually shoot hand-held. I did a few hand-held test shots with and without the tubes and once cropped, the 24-70 on its own performed better.That said, on a tripod with plenty of light and a fixed subject, they work brilliantly. I’ve not tried the focus shift (focus stacking) on the Z6 so I can’t offer any advice on that.I think that if you put these tubes on the super-sharp Z 85mm F1.8 you will get spectacular results (especially with a tripod). As I mentioned earlier, I’m only an enthusiastic amateur and maybe more experienced photographers have the knowledge to overcome the problems I had with them. I cannot fault the build quality and value for money.Amended: The 11mm ring can focus from about 24" from the focal plane of the camera, which allows me to move in closer to my subject if necessary. From its closest range of about 8" (focal plane) I get about a 1:2 magnification with the 11mm and easily 1:1 with the others. They also work with focus shift as well. According to some research online about ext rings and magnification, the Z85mm won't give better than about 1:4 as its closest focus is 0.8m, so even with all the rings attached it's still not very close. However, the same research suggests the Z50mm is the probably the best prime to use with these rings Just bought a sigma 105mm macro as I like the lens anyway but now I can keep the 11mm ring in my bag and always have a handy little macro attachment without carrying the 105 around.Still 5 stars..

Die Ringen passen - sehr gut - lassen sich leicht und gut anbauen - rasten praezise ein - ohne zu klemmen.Alles wird korrekt uebertragen der Fokus funktioniert einwandfrei keine Fehlermeldungen.Ob das Teil nun Plastik oder Metall ist - ist mir ehrlich gesagt egal - es tut was es soll und der Preis ist hervorragend.Absolute KaufempfehlungBeste Gruesse Bernd

Delivered without rear and front caps (as others do), the bayonet mount is not as stabile (tight) as at Meike, which seems otherwise very similar (bur has (11mm and 20mm long rings). The price for both is the sameThis is only the first impression as unboxed, up to now not tested.
