Enhance your vision with the Nikon DK-20C +2.0 Diopter, compatible with many Nikon DSLRs. Ensures clear, sharp images. Shop now for optimal focus!

Take your photography to the next level with the DK-20C +2.0 Diopter, specifically designed for a wide range of Nikon Digital SLR cameras. This optional Nikon eyepiece diopter is engineered to enhance your SLR viewfinder's sharpness, tailored to your unique eyesight. Unlike standard eyepieces that come with Nikon SLR cameras, which serve primarily for dust protection, the DK-20C +2.0 Diopter offers a corrective value. This is identified by a plus, minus, or neutral numeric diopter value. Some select eyepieces even come with a rubber coating to minimize scratching on eyeglasses, making it a thoughtful choice for photographers who wear glasses.Nikon SLR cameras without built-in adjustable eyepiece correction have a base diopter value of minus one, considered the optimal starting point for most SLR users with normal vision. The DK-20C +2.0 Diopter, along with the camera's viewfinder components and a clear standard eyepiece, forms a virtual image of a subject on the camera's focusing screen. This is roughly equivalent to a viewing distance of one meter.Each Nikon eyepiece diopter, including the DK-20C +2.0 Diopter, incorporates a numerical value. This is represented by a minus value for nearsighted users or a plus value for farsighted users. This allows you to select the appropriate diopter for your vision and your camera model. The eyepiece's diopter value, combined with the viewfinder's minus one value, gives the end-result value. For example, if you require a diopter of plus 3, simply add a plus 3 diopter to your camera. Neutral correction eyepieces do not replace the supplied standard eyepiece but change the diopter value of the camera from minus one to zero. To determine the best Nikon diopter value for you, consult with your ophthalmologist, optometrist, or dispensing optician. They can help determine your diopter from your corrective prescription when viewing an object at a distance of approximately one meter. Please note, some Nikon SLR Cameras have built-in adjustable eyepiece correction. Refer to your instruction manual to see if additional threaded Nikon eyepiece diopters, like the DK-20C +2.0 Diopter, can be combined with your camera's built-in diopter control. For cameras with built-in diopter control, use additional Nikon eyepiece diopters only if your vision dictates that optimum viewfinder sharpness cannot be achieved with the built-in diopter adjustment control. In summary, the DK-20C +2.0 Diopter is a valuable addition to your Nikon Digital SLR camera, designed to optimize your viewfinder's sharpness and cater to your individual eyesight needs.

Great

Exactly what I needed to stop wearing my glasses on photo shoots.

Great Product

Item just as advertised. Very quick shiping

Works Great

The diopter adjustment worked very well and was easy to install

Diopter Correction Eyepiece

Since my eye surgery, using my Nikon 7100 has been difficult. This diopter solved the problem.

Focusing is easier

I'm glad these supplementary viewfinder eyepieces exist, in my case a +3.0. Many Nikon cameras short those of us needing viewfinder correction on the plus side. These add-ons make viewing a pleasure without the bother of wearing eyeglasses, which bring their own set of problems when operating the camera. You should remove the viewfinder rubber surround before fitting the diopter. It can't be used with the diopter lens. I highly recommend this inexpensive product unless you're happy wearing glasses while photographing.

I'm happy with the Nikon DK-20C +3.0 Diopter

eye correction lens

After figuring out that the protective eye piece had to be removed before installing the diopter, the view was so blurry that I had to remove it.

Very misleading

Ordering on-line was easy. Shipment was quicker than expected. I matched the diopter with my reading glasses but seems to be to strong. The only disappointing thing is that the rubber eyepiece does not slip into the grove of the new diopter, the grove is smaller that on the original.

 I matched the diopter with my reading glasses but seems to be to strong

The original diopter corrector embedded in the camera is almost in the borderline of my sight. So, by using this diopter corrector plus giving it the fine tunning with the camera one my view became a 20! However; I don't like the fact that the rubber viewfinder protector can not be used anymore! Nikon should develop the DK-20C so the rubber protection be use it on it!
My 10 cents!

Useful accesory

I have on on my D7200 and D80. Works well.

If you need it you will like it

I purchased an -2 diopter.  My glasses were too strong and the negative 2 worked excellent I could use the D7000 diopter adjuster to dial in my correction totally awesome!!!!!!!

Great fix to my camera!!!!!!!!

Best thing since poloroid; just kidding, works really well for those of us who are trying to get manually focused while burdened with lousy vision but love photography, should have bought this years ago.  Especially useful at longer focal legnths!  Mike

Absolutely great

A must if you want to focus through the lens and you're nearsighted like me.

Works with D3300

It's like reading glasses - if you need it - get it.

I use when I wear my contacts

Product as described. Critical as I don't shoot with my glasses on.  Ask your eye doctor how much correction you need and get more then use the diopter adjustment.  Just wish Nikon made it easy to put these on.  They are NOT easy.

A must if you need

The diopter correction eyepiece works well with a new D750. Easy to install / remove and effective as intended. But the eyepiece is similar to some other Nikon corrective eyepieces: It does not accept eyecups (at least, any that I've found - suggestions welcomed). Can be troublesome in bright sunlight. So, just pick your situation in which to use it.

Works well, but... eyecup?

Can't rate product since I ordered the +2 thinking  that was what I needed  since my reading glasses are that strenght. Big miss. Not worth the hassle to return because of the price. I will get the right one, once I visit my eye doctor and she tells me what the strenght should be. No problems fitting it into my D5000, the only thing is you will have to McGyver the rubber eye protector that came with the camera, otherwise it does not fit once you put this adapter in

Follow order instructions

It works perfectly with my viewfinder. Now I have to remember to take my glasses OFF! I can live with that.

Perfect!

It should come with installation instructions

nikon diopter

20/20 vision as a young wippersnapper, older than dirt now and this is a neccessity when using the viewfinder!

Needed this

Fits directly onto the camera and allows the eye ring to be fitted onto the diopter.

Allows me to use the viewfinder without my glasses. You just need to know which strength you need. I asked my optometrist.

Helps with Near Sighted viewing

It worked great. I was at the end of my adjustment on the camera, and now somewhere in the middle. I can finally judge focus without using glasses!

Excellent Product!

I got a Nikon 7100 — the only SLR I've used since I rented a Nikon and three great lenses for a trip to the Florida Keys in about 1975. I loved shooting that holiday, but have not had an SLR in my hands five times since then.

My eyes were very good until I began to age; now I'm 64 and currently trying trifocals. I use +2.5 reading glasses for computer screens, higher for books.

With this little lens inserted and a quick adjustment of the camera diopter, the focus through the viewfinder snapped like it had when I was 25. It is an enormous treat — my world is never in focus like this any more.

Before the DK-20C arrived, I had the in-camera diopter adjusted to work with the long  focal length of my trifocals; that was okay and no doubt I'll shoot that way a lot of times again, but with that setup I had to scan around the edges of the viewfinder to establish framing — and 'right focus' was a little too much hope and too little confidence.

There is plainly plenty of room for me to adjust the camera diopter as the months and years pass, so that I feel quite assured that this device will work for me (like this!) for years (or until I lose it and have to get another).

The nice way the D7100 puts the shooting controls on the right under hand means that, effectively, once I have located a subject with my glasses on I can inspect it, adjust and shoot, without needing to put them back on.

I'm just really happy with this and recommend it highly to someone who has aging eyesight.

Very satisfying

Best part - is just what my eyes need when not wearing glasses by letting me see more clearly through viewfinder.  No fun using the viewfinder with glasses.  The not so good part - came partially off when putting camera in bag, and ended up breaking one of the holding arms on the diopter.  Now to order another.  In fact, ordering 3 more.  If you buy - buy extra. But I do highly recommend if you don't like wearing corrective eyeglasses when shooting.

No more shooting with eyeglasses on!

I have 2.5 correction glasses so this was necessary to correct the diopter.  Easy to install and works, but the eyecup is difficult to re-install after the diopter is installed

works, but eyecup a problem

My eyesight is corrected using monovisison where my left eye is corrected for reading and my right eye is corrected for distance vision.  Since I use my left eye with my Nikon D300 viewfinder I needed more correction than the -2.0 diopter adjustment available through the camera viewfinder. The DK20C -2.0 snapped onto my eyepiece giving me a total of -4.0 diopter which was perfect for my needs.  Up till now I have struggled with a fuzzy viewfinder view.

Worked Great

Simple product that works as described, however it was a VERY tight fit with the rubber eyepiece that came with my D7000.  I had to file the edges of the diopter for the eyepiece to slip over it.  I am not accustomed to using carpentry tools on Nikon products...

Very tight with D7000

My perscription for reading is +2.25 but +1 puts the adjustment just right (for arms length).  Glad I didn't buy the +2.

I can see clearly now...(in viewfinder)

If one is nearsighted or farsighted a diopter correction eyepiece for your Nikon is a must.

They work!

Intallation takes about five seconds and badda-boom it's done.
