I was given the opportunity to review one of the new the Blackstone 15mm f2.4 IRIX Nikon mount lens on my JVC GY-LS300.
Here is my micro review…

I like your blog and I was eager to read your test about the Irix 15mm, you have been announcing long ago. I own, like you, a JVC LS 300 and I look for a wide angle. I’m a bit disappointed with your micro review. It’s far too micro for me. Not a word about resolution neither vignetting. OK, we can find that stuff elsewhere. But you explain in the video that you use a Nikon-MFT adapter, with no electronic connections (thats what I use with my set of AI-S Nikkors). The question is how to set the aperture. There is no ring to do it manually on the lens (I think) and you can’t use the camera (no connections). On my Nikon-Mft adapter, there is a ring to open and close the stops on the Nikkors. Does it work in the same way with the Irix. I’m sure that many readers and watchers of your blog would like to know more about this glass. More technical details.
Sincerely,
Guy
HDW : It’s called a micro review for a reason, I don’t go into resolution charts etc. The MTF has a ring which I don’t mention in the review to open and close the iris on the IRIX Nikon mount. Not very accurate I’m afraid.
