Gutes 10mm Objektiv für Nikon Z (Vollformat). Es ist aber kein Objektiv. dass eine 180°Rundum-Abbildung kann. Das geht mit einem 4mm Objektiv, wobei ich da noch keines für Vollformat gefunden habe. Objektiv ist jedocj für seine Größe relstiv schwer. Wer Autofokus gewöhnt ist muss sich erst an dem manueallen Fokus gewöhnen. Mich stört es wniger, das ich das Objektiv hauptsächlich für Astrofotografie nutze,

Objectif très bien construit et qui a un piqué de bonne qualité une fois qu’on arrive à maîtriser la mise au point manuelle. Très content de mon achat.

Obiettivo con risoluzione molto buona da f5.6 anche ai bordi. Di fatto è un 11.5 mm. Pesante ma ben bilanciato sulla macchina.

Buy it. Buy it buy it buy it. Genuinely unbelievable. I'm a lens snob. I use G masters and high end Sigmas. I bought this expecting it to be a cheap way to experiment with 10mm. I have other $200-$400 lenses that are pretty soft, low contrast, so wasn't expecting much. I certainly wasn't expecting a new favorite. It's now my first choice and lives on my A7R3 more than any other lens I own.Tack sharp. Nice contrast. You're gonna think I'm crazy for saying this - cropping this 10mm into 35mm actually compares to my Sony 35 1.4 G master (a $1600 lens). Yes, cropped in you lose pixels, but the optical quality is like 90+ percent the same.It's made me not worry about takint the 35mm 1.4 GM as often, because this is nearly as good cropped in if I need a tighter shot, and it's a HUGE amount to crop from 10mm to 35mm.Pretty easy to correct the fisheye effect in Lightroom, so don't pay more for a rectilinear lens. In fact I strongly prefer the wild fisheye for creative uses. It's awesome to aim straight up at the sky and still see two horizons on both sides of the image. AND have everything be sharp when you pixel peep. That's the insane part. You'd expect it to just be a blurry mess at that kind of wide angle, but no, not even close. Granted I have 42mp behind it, but that speaks to how much this lens can resolve.I cannot believe the price. With autofocus and f1.4, it would be a $2000 lens. With just autofocus and f2.8, I'd still pay $1200. As it is, manual focus and f2.8, I still think it's worth $600, almost in Voigtlander territory. And yet it's 1/4 the price of a Voigtlander, and 1/10th the price of a Sony G Master.The only thing I'd change is making the aperture clicky, or have a switch for it, or a lock. I accidentally moved it to f4 or f5.6 so many times while shooting video. You have to hold the lens far back to keep your hand out of view, so you're gonna move the sensitive aperture dial by accident, guaranteed. But do not let that stop you from enjoying this incredible lens.Oh yeah, the build quality is awesome too. Solid, heavy but not too heavy, all metal. Feels nicer than my Sony lenses for sure. Not as nice as a vintage FL mount Canon lens, or a Leica or something, but way above the modern Sony/Canon/Nikon lenses which still use plastic even for their high-end line.I digress. Go buy it.

I bought this to use as an Astro lens for my Canon R6Mk2. The lens is solid and well made. It comes with a handy leather case. Its totally manual with regard to focus and setting the aperture. The infinity focus is just on the "infinity symbol". Stars are pretty sharp edge to edge. Using f/2.8 there is a little distortion to the edges. stopping down a little these disappear.The 10mm and the 183degree gives me horizon to horizon view. Great value for the price and its native RF mount too.
