The Nikon P7100 is Nikon’s premier Point and Shoot camera. Point and shoot is an oversimplification because the camera does offer raw image format for better post processing and a viewfinder which is often useful in bright sunlight. It is also one of the few compacts designed to accept filters and accessory lenses easily. While Nikon makes only one accessory lens, the WC-E75 wide angle converter, there are a number of third party providers with other lenses. I have the WC-E75 and the Raynox 15o macro converter. Both require an adapter tube for operation. The WC-E75 is designed to work with the Nikon UR-E22 and the Raynox uses a pinch type filter mount and will work with any adapter.
The photo on the left here shows a generic Polaroid branded mounting tube with the Raynox mounted and the Nikon UR-E22/WC-E75 combination. The right photo shows the Raynox ‘macroscopic’ lens with it’s pinch mount. The base of both tubes is the same. It has a bayonet type mount that surrounds the P7100 lens. You simply remove the cosmetic ring that covers the mount and place the tube on it. Once on, they look like this.
Raynox on the left, Nikon on the right. There is a difference in the mounting tubes. The generic tubes come in two pieces and allow the camera lens to be zoomed. When the shorter one piece Nikon UR-E22 is mounted, the lens is retracted to it’s wide angle position. There is a reason for this. If you click on the picture above, you will see that the fixed zoom of the P7100 is almost touching the back of the wide angle converter. Attempting to zoom with that on the camera could cause damage to the lenses or zoom and focus motors. The WC-E75 turns the 28mm wide angle position of the P7100 into a 20mm equivalent.
Using the Raynox is equally simple. Just put the tubes on the camera and put the Raynox 150 on the end of the tubes. Unlike the UR-E22, these tubes allow you to use the zoom capability. It is in two pieces so that at the wider end, you can still use filters if desired. That isn’t necessary for the macro adapter though because you will normally be shooting at the long end. Shooting at the short end doesn’t give you much magnification and does produce a lot of vignetting. Here are two shots at 28mm and 200mm equivalents using the Raynox. There is actually an ant in both pictures.
The vignetting and lack of magnification at wide angle is obvious. The raynox does not give the high quality of a good macro lens but, for non interchangeable lens cameras, it’s two element design is about as good as it can get. The pinch mount also means that you can use it on other lenses. Here is a shot of Spanish Needle seeds straight out of the camera and cropped for more detail. The individual seeds are about 1/4 inch long.
I am happy with the combination and it’s easy enough to carry around in a jacket pocket. Even easier in a small belt bag.
I have a Nikon P7100 and wonder if your mention above, “there are a number of third party providers with other lenses,” who those providers might be? I am looking for a 2x lens that would fit into the WC-E75 or the Raynox 150. I bought a lense and tube from Amazon and it was mechanically unreliable (it would fall off). I am a novice and am not sure what is considered good but also reasonable in cost. Thanks for any help. Rob
I tend to stick to name brands from places that are easy to return to. The tube I have is branded Polaroid but there are many others with varying degrees of quality control. The tube and lens are seperate components. If your tube won’t stay on the camera there is something amiss with the locking pin mechanism on either the camera or the tube. I would suspect the tube. To check, if the cover ring will lock in place and the tube won’t, then the camera pin is working and the notch it locks in to on the tube is not right. The pin is the little metal bar that is next to the release button. Just press the button and you will see the pin operate.
Since the Raynox works for many sizes with it’s pinch mounting needs to be secure. It might fall off the tube if you happen to bump one of the ears. I only have it on the camera when I am taking a picture to avoid that. The WC-75 is a screw on device and I have never had a proble with it coming off.
Thanks for your helpful comments. Rob
