Quality exudes from this lens, the finish and markings are flawless, the focus is smooth and the focus lock is a nice added bonus as is the tripod collar that locks perfectly on my Really Right Stuff ball head. The hood fit well with a reassuring click Removing the hood however is easy with the lens facing away from you and grasping it with your right hand on the top, other positions may frustrate you as the hood doesnt seem to want to come off otherwise. The lens came with front and rear covers, the rear cover has been put away and replaced by a Nikon one as it was loose fitting and I didnt want to lose it. The packaging was fantastic, it arrived in a sealed box, and come with a semi-hard fitted zippered case which was another unexpected surprise. I received this lens in mid december 2018. “I ordered this lens because I wanted to be further away from my subject than was possible with my Nikon 105mm f/2.8 AFS micro. I am very happy to add this lens to my kit!” Last note: the manual focusing turns through 270 degrees, and is extremely smooth it is precisely what I want and need in a lens like this. I especially appreciate that the collar has an Arca-swiss compatible foot fits on my RRS BH-40 ball head & clamp perfectly. I have not yet used the Irix much at all, but on its maiden voyage (into sub-freezing weather, with my fingers moving slowly) it was super easy to use and seems to give superb results. I have now sold the Tamron with no regrets. So when I learned of this Irix 150 I decided to try it. But once I got my Nikon Z7 I found the Tamron caused the Z7 to do weird things (such as a bunch of weird clunking sounds in the Z7 each time I turned it on with the Tamron 90 mounted). I even had it get internal debris TWICE, though Tamron removed debris both times without hassle and at no cost to me. “I had the critically-acclaimed Tamron SP 90mm f/2.8 Di Macro 1:1 VC USD lens was never all that thrilled with it. This is my first lens by Irix but it wont be the last” Minor problems though when you consider the image quality and the fun of using a manual focus lens like this Irix. Maybe in time itll loosen up a bit, but for the moment it takes a small amount of force to remove it and reattach it to the lens. Ive attached a RRS lens foot to make it just a little longer, and the RRS lens foot also has two safety screws to keep the lens from sliding out of my ballheads clamp. Now for the two minor problems, no big deal but the lens foot is pretty small. The fit on the K1 is perfect, it balances very well on that camera. The lens looks and feels professional and is a little heavier than I expected, but thats a good thing for me. I love the focus ring, especially the focus lock feature where I can dial in a little resistance for dampening. Its great looking and has a nice feel and the photographs from my K1 are bright and sharp. “First let me say that Im enjoying using this lens. Special texturing allows for reliable and precise focusing, and dedicated embossing allows you to feel the position of the ring, making sharpening even easier. The rotation angle of the focus ring on the Irix 150mm f/2.8 Macro 1:1 is as much as 270 degrees, guaranteeing extremely smooth and precise sharpening.įocus ring ergonomics – after tireless testing, we have developed a material characterized by its high mechanical strength and resistance to adverse conditions. Thanks to this solution, the center of gravity of the camera lens remains neutral, and the vibrations associated with focusing and operating the camera are minimized.įocus ring – when shooting small elements, depth of field usually covers only a few millimeters or less, so it is important that sharpening is precise. We have good news for all photographers using a tripod: thanks to the tripod clamp, you can safely and securely attach your camera to the lens. Tripod clamp with foot (Arca Swiss standard) – macro photography requires extraordinary precision. Focus Lock – allows you to lock the focusing ring in a specific position, which is extremely beneficial when you want to be sure you set the correct magnification ratio, e.g.
