First of all you have to know what you are getting here. Basically this is a microscope lens placed in something that allows it to be used on a camera. As someone who uses microscope a lot yous have to appreciate at these magnifications your depth of field is razor thin. So to be honest probably the all-time manner to utilise this lens is on a macro slider, have multiple shots, then combine the images using software. That noted the lens, amazingly has a the ability to be stopped down to f16 (range f4-f16) with it'due south bizarre 3 aperture blades.I do this to increment, perhaps infinitesimally, the depth of field. When I do stop the lens downwards and haven't seen a terrible loss of sharpness, only I haven't really evaluated this lens scientifically. To exist articulate here, You FOCUS BY MOVING THE WHOLE Camera. Yep, I accept used it in the field with a macroslider and some additional light source needed with this lens. I use a telescopic with two LEDs and it works well. It is easier with the K1 considering you can use the moveable screen for macro piece of work. Personally I apply it mostly to document some of my really tiny seashells, we are talking about ones that are less than a cm in size, some of them half that. I have also used it professionally to photograph tick nymphs for id. It does open a whole world for you IF that is where you want to get. I don't have it merely a couple of the Laowa lenses are its all-time competitor, more functional anyway, simply probably twice as much. DON'T make this your outset macro lens; you will hate information technology. Practise become this lens if yous are on a budget and want these kinds of magnifications. Make certain you lot have a macro rail/slider and additional lighting. Warning: Being careless I put the lens on without matching the ruddy dot. I was getting an insect epitome, was in a hurry. Anyway, different every other lens I have it unfortunately went on my K1 in the wrong slots and couldn't come up off! I ultimately had to accept the lens cut off! I replaced information technology, lesson learned. If you get the lens, don't make my mistake.  | | | | Site Supporter Registered: Oct, 2009 Posts: 692 | | Lens Review Date: March xi, 2020 | I can recommend this lens: Yes | Price: $200.00 | Rating:ix |

I did not sympathise what a 4-iv.5x lens meant when I purchased it. Initially I was disappointed, and put the lens away for half dozen months. The lens is a groovy value when yous consider what it is designed to do, and the low cost of the lens. It is probably best described as a microscope objective for the forepart of your photographic camera, non a traditional lens. Equally such, it is not designed with a focusing band. One focuses past moving the camera forward and backward until the object is in focus. The extreme magnification & shallow depth of field means that a handheld image in practiced focus is in non possible for me, even if I could find an object shallow plenty to brand a good photo. If there are whatever dust spots on your sensor, await them to actually show upwards at this magnification. The lens is designed for very tiny objects, or focus stacking of sightly bigger objects. The depth of field at f2.0 is so shallow that a manual macro rail, while possible, is challenging to employ. It would be all-time to use an automated rig if yous can afford one. I've only used this lens for one session, as I don't accept much time for the fourth dimension consuming edit one must practice to put together a decent stack. Here is an paradigm stack (76 images) I took of the height half of a butterfly weed flower using the Grand-1 with the lens at 4x, 1/200 second. The shutter should be faster. I took it with a narrow aperture (did not record), so it is diffraction challenged. The instructions recommend y'all use it at f2.0. I practise not believe that I tin can advance the macro rails manually in fine enough increments at f2, so it was a compromise. There were plenty of slices missing as it was. Information technology is also natural lite, outside, on a medium duty tripod with manual macro rails. Best result would be studio lighting and/or flash with an automatic macro rail. With that in mind, hither is what I was able to accomplish with less than optimal conditions and gear. Corking for $200. It is less expensive and easier to employ than the Nikon plan acromat microscope objective I purchased for tiny objects. The outset image is the stack and edit, downsized for easier viewing. The second is an actual pixel crop.

A tragedy
Just as well the lens is cheap. I tin can't go any usable photos from this lens. Maybe I have a bad copy, merely the images await icky. I take a very solid rig to mountain the camera to a focusing rail. To confirm the rig works, I used a canon camera with the X5 60mm canon ultra macro lens. I become excellent photos from this setup even though I would get less shake from my pentax setup. It's difficult to sympathise the difference unless my Zhongyi Mitakon 20mm is shonky. The lens will gather dust in my lens cabinet. Happy for whatever users of this lens to provide their communication. | | | | New Member Registered: Oct, 2013 Location: Richmond, VA Posts: 21 3 usersouthward found this helpful  | | Lens Review Engagement: November 27, 2017 | I tin recommend this lens: Yes | Toll: $199.00 | Rating:N/A |

I picked upwardly this lens expecting it to work like my other macro lenses. I didn't do my research and empathize what this lens really is before I bought it, and that'due south on me. This lens is an extreme macro lens. There is no focusing ring, you focus information technology by moving the camera. To reach focus you need to exist 0.8" (20mm) from the subject. While there is an aperture band, fifty-fifty with it stopped all the style down, the area in focus is crazy sparse. Because of that, using a tripod is a nigh necessity. Due to the size of the front element, you lot'll need a lot of light on the subject which in some instances will be a claiming due to how close yous have to be to reach focus. One more quick note, there is no aperture actuator like you'll see on other One thousand-Mountain lenses - this is basically an extension tube with a tiny lens on the front. It is possible to become some good images with this lens, but be aware that information technology's a dissimilar kind of creature than you may be not used to and that information technology will take some trial and error to get information technology correct. EDIT: I was asked to upload some sample images, and so here you get. These were shot handheld in natural light at 1/200 and ISO 12800   | | |
