Sure the D300 has a bright display but this makes it even nicer. Now if I had perfect eyesight I might not be as enthusiastic about it but it will help me do a better job focusing so it's worth the price. Hehe...unusual for a Nikon accessory.

The magnifying eyepiece works well in the sense that it makes manual focusing easier. For a person wearing glasses, however, it does make it difficult to see the entire viewfinder on a D300 or D200. This makes the accessory only useful for tripod work with non moving subjects. It would be great for macro work, not so good for sports.

    Comments about Nikon DK-21M Magnifying Eyepiece:

    Using a Nikon D200 and Nikkor 55mm f3.5 with the Nikon PK-13 to digitize old 35mm slides. This magnifying eyepiece makes the target focus much easier to see and adjust. It's a very useful add-on to my trusty D200 viewfinder.

        Comments about Nikon DK-21M Magnifying Eyepiece:

        I'm a tri-focal wearer and after adjusting the diopter for the magnification, I get a much better view of the finder now. I put my Hoodman eye cup on and even with glasses it is workable for quick shots. Added benefit is pushing my face back from the camera. I am left eye dominate and this helps get my nose away from the buttons and preview screen.

          Comments about Nikon DK-21M Magnifying Eyepiece:

          I have eyesight problems and find the 1.7 power helpful with close work and manually focusing. I do need to mention when using a zoom lens remember the 1.7 magnification when framing the shot.

                Could it have been an isolated eye piece? I don't know, but the DK-21M that was shipped to me, I felt perhaps magnified things "a little bit" but made images way to blurry in the viewfinder. Not worth it for me.

                  It's a simple add-on intended to magnify the ridiculously small viewfinder image in particular entry-level DSLRs. It fits, and does its job. The description above says it magnifies the image 1.7x. That is incorrect: it magnifies 1.17x which isn't much, but every little bit helps.

                    This eyepiece is quick and easy to install. It fits securely on my camera (D90). I use this when I need to make fine manual focus adjustments, for example when working with shallow depth of field or macro. It does make it easier to make focal adjustments, but it is a modest improvement at best. Anything that helps me take better pictures is a positive in my book. Anyone expecting a $[$] eyepiece to make a dramatic difference in the performance of the viewfinder on an expensive camera is being unrealistic.

                    Makes a slight difference but still useful. Considering the price I wouldn't buy it, I had extra credits so it was a why not type of buy. Its important to note that if you're wearing glasses the improvement is hindered a little bit.

                      Provides just enough added magnification to manually focus my wide angle lenses in poor light. Fits the D200 perfectly and the lens appears to have a very high quality multi-coating on it. Read some reviews stating that the rubber eyepice of the DK-21M was "hard" compared to the stock eyepiece, and that it bothered users' eyebrows. Yes, it is a harder rubber but I'm not sure what the complaint is. I notice no difference in actual use. A great addition to the camera and the price is a bargain.

This extender was made in Japan so you can trust is build excellent and you will see clear like nothing is there .

                                I wish it had more magnification. It doesn't help much.

                                I was hoping for good quality sharp device that will allow me to see display inside D7000 view finder a bit better. Unfortunately DK-21M is loosing sharpness in the corners (!), and display is out of view, unless you move eye up a bit above the center line.
                                I will consider product return.

                                  Comments about Nikon DK-21M Magnifying Eyepiece:

                                  Enough magnification to make manual tweaks to autofocus slightly more precise, but not enough to make a dramatic difference. I wear eyeglasses, and found I was losing a bit around the edges of the frame, but not to the extent that it made composition difficult. I decided to carry this with me but not keep it on the camera (a D90) all the time; it only takes a few seconds to snap off the standard eyepiece and replace it with this one.

                                      I use this for better manual focusing. Autofocus is somewhat limited for my type of photography and I need better control.
