The 4x Aspheric Loupe from Rodenstock will minimize stray light even against very bright backgrounds. The base is built with a sliding hood that easily converts the loupe from opaque (for viewing film) to clear (for prints or ground glass focusing).

The multi-coated glass has been chosen for its high-quality and ability to minimize reflections. Your image will be sharp edge-to-edge, free from any distortion. The detachable neck strap gives you the freedom to roam around your office or studio and have the loupe handy when you need it.

    Pros

    • Bright

    Cons

    • Cheap feeling

    • Poor Construction

    Best Uses

    • Ground glass focusing

    Comments about Rodenstock 4x Aspheric Loupe:

    The optics are impressive and bright helping me focus my view cameras, but I feel the outer body construction is a bit poor and low rent. A plastic ring separating the retractable hood from a light diffuser fell out and is now precariously replaced. Not what I had hoped for but keeping it because the optics are amazing.

    A must for precise focusing in the field

    By Rebecca

    from Delaware

    About Me Photo Enthusiast

    Verified Buyer

    Pros

    • Diopter Adjustment
    • Easily Cleaned

    Cons

      Best Uses

      • Photography

      Comments about Rodenstock 4x Aspheric Loupe:

      I use the loupe for focusing my 4 x 5 in the field. The size is compact, but large enough to get a good radius for detail focus.One of the primary reasons I purchased this particular Loupe was because I now must wear bifocals and it has been becoming more and more difficult to get a clear focus on the ground glass. With this loupe I have the ability to adjust the diopter. It provides continuous adjustment rather than stepped, which makes adjustment easy and precise.

        Comments about Rodenstock 4x Aspheric Loupe:

        I use the lupe for focusing on groundglass for large format photography and the 4x is perfect, not too wide but not too tight so the grain on the glass itself isnt obscuring the image and makes focusing really accurate. A smartretractable hood to let light in over the surface you look at, and a diopter makes this perfect for GG focusing and checking negatives.

              Comments about Rodenstock 4x Aspheric Loupe:

              I use this loupe for examining negatives and for focusing the ground glass image of my 4x5 camera.
              The loupe is very bright and has excellent definition. The field of view is large. To focus the image in the corners of the ground glass I reverse the loupe and hold it a small distance away form the ground glass surface.
              The focus mechanism is smooth but a bit looser than I would like. By winding a couple of flat rubber bands around the barrel of the loupe just behind the rubber eyecup a pre-set focus stays put.

                    Works Great!

                    Excellent for ground glass focusing.

                    Plastic face runs smooth on the glass, it's light in weight and easy to carry.

                    The optics are excellent.

                    The only down side is the dioptre adjustment is rather loose. Some people have suggested adding a small screw to fix it into position, I might try it.

                      • Traditional Prints

                      Comments about Rodenstock 4x Aspheric Loupe:

                      The Rodenstock 4x Loupe is an ideal product for viewing slides and negatives on a light box, and because of the built-in retractable clear hood, it also works very well for viewing prints with reflected light. A third use, and one of equal purpose to the slides, is that of focusing on the ground glass on large format cameras -- here, the height is an added asset.

                      I have read some complaints about the loose diopter adjustment. It is on the loose side, somewhat like using an AF lens in manual mode; a manual focus lens offers more resistance for finite movement as well as less drift.

                      The optics are crystal clear, which honestly reflects the brand name and the price.

                      Once again, the built-in retractable clear hood is a major selling point.

                        Comments about Rodenstock 4x Aspheric Loupe:

                        I really like the plastic housing over the higher priced all metal units for groundglass viewing.
                        The plastic is easier on the glass for ware factor. It is light weight also. Maybe a square design would improve extreme corner access, but I've not had any issues with the design to speak of. The diopter adjustment is too loose. I actually took a small pin drill and cored a small hole and installed a small set screw. Resolved the diopter movement issue all together.

                            I needed a loupe for working with negatives on a light table and focusing images on a ground glass so I did close comparison of a few. This is a very nice loupe. There were two things I didn't like about it. The first is the diopter adjustment was too loose, I much prefer the adjustment on the Schneider loupes. The second is the optics are constructed in a way that allow the image to be cut off by a changing the how you look through the loupe. I'm not describing this well. I only noticed this by way of comparison to the Schneider 4x loupe which did not exhibit this characteristic. Acceptable spherical distortion at the edges comparable to the Schneider 4x. Has a built-in retractable clear hood for viewing with reflected light. All loupes should have this style of hood. Photographers have enough little pieces of stuff to carry around and loose, we don't need yet another piece. Has a soft rubber eye-cup which I like. Diopter adjustment smooth but very loose. It needs a little more friction to prevent it from going out of adjustment easily. I can imagine a situation where I would be spending my time adjusting the diopter on this loupe as well as the focusing an image on the ground glass, not something I look forward to. Neck strap mechanism functional and simple. Repair or replacement of neck strap would be trivial which is important.

                            Comments about Rodenstock 4x Aspheric Loupe:

                            I use my Rodenstock to view film and slides for focus and to identify any artifacts that may need my attention prior to scanning.

                            The 4x is a great loupe for reviewing the entire slide or negative. The large piece of aspherical glass has great eye relief.

                            I have no cons to report. This is a great loupe.
